Listen to David Bowie's First Album in 10 Years for Free Online (Legally)











You don’t have to wait until March 12 to find out whether David Bowie’s first album in a decade is more Tin Machine than Low; the long-awaited The Next Day is already available, streaming in full on iTunes for a limited period pre-release.


The stream continues Bowie’s current interest in previewing content from the album for free online before release; videos for both “Where Are We Now?” and “The Stars (Are Out Tonight)” debuted on YouTube in the last month with little fanfare, like this stream. Although iTunes’ page for the stream lacks any information about the individual songs, The Next Day’s track listing is as follows:


01. The Next Day 3:51
02. Dirty Boys 2:58
03. The Stars (Are Out Tonight) 3:56
04. Love Is Lost 3:57
05. Where Are We Now? 4:08
06. Valentine’s Day 3:01
07. If You Can See Me 3:16
08. I’d Rather Be High 3:53

SpaceX Reaches Orbit, But Problem Delays Power Supply



Update 10:40 a.m. EST: The Dragon spacecraft is in the proper orbit, but there is a problem with the spacecraft itself. Elon Musk messaged that there is an “issue with Dragon thruster pods. System inhibiting three of four from initializing. About to command inhibit override.” More details will be provided as they become available.


Update 11:10 a.m. EST: It appears the problem with the thrusters on the Dragon is keeping SpaceX from  deploying the solar arrays. There are 18 hours of battery life on board the Dragon that can be used during the flight, but for more duration, the solar arrays are needed to generate power. Elon Musk’s latest tweet reads, “Holding on solar array deployment until at least two thruster pods are active.”


Update 11:50 a.m. EST: SpaceX waited until the Dragon was over a ground station in Australia to communicate with the spacecraft, overriding an inhibit instruction that was preventing two of the three thruster pods from working properly. The pressure in one of the two inoperative thruster pods was “trending positive” according to Musk and the team was able to successfully deploy the Dragon’s 54-foot-wide solar arrays that will allow the spacecraft to generate electrical power. SpaceX says the delay in the deployment means there “may be a rearrangement of the planned burn sequences for the Dragon spacecraft” as it approaches the ISS.


SpaceX successfully launched its third flight to the International Space Station this morning carrying more than 1,200 pounds of cargo as part of the company’s ongoing orbital trucking contract with NASA. This morning’s launch was the first daytime launch of the Falcon 9 from Cape Canaveral, with the liftoff taking place at 10:10 a.m. EST.


After a hotfire test on Monday, the Falcon 9 was returned to its hangar at launch complex 40 earlier this week where final preparations were made for today’s launch. This is the third flight of the Dragon spacecraft to the ISS, but just the second contracted cargo mission for NASA. The first flight last May was a demonstration mission, though a small amount of cargo was delivered.


At the pre-launch press conference on Thursday, SpaceX’s Shotwell explained for the first time the root cause of the engine shutdown during the last Falcon 9 launch to the ISS in October. She said the SpaceX team traced the problem to a “material flaw in the jacket of the engine.”


Shotwell did not elaborate on the nature of the flaw, saying a final report was still being wrapped up and that the rocket engines are one of the main things covered by the International Trade in Arms Regulations (ITAR) the company must follow.


“I don’t look good in horizontal stripes,” she said half jokingly since breaking ITAR regulations could result in jail time, “and I want to see my kids graduate from college.”


The flaw in the jacket of the engine led to a breech causing a “depressurization in the combustion chamber. Though the engine did not explode as initially thought, Shotwell was quick to point out the upside to the failure. She told reporters the engine shutdown did show the redundancy in the Falcon 9 design works.


“Though you never necessarily want to see it happen,” she said of the eight- (out of nine) engine boost to orbit, “it’s nice that we’ve demonstrated the vehicle as it was designed.”


Today’s flight includes numerous scientific experiments, including one that will be both carried up by the Dragon spacecraft, and carried back to Earth when Dragon departs the ISS. The return schedule is partly dependent on the successful completion of the research, according to NASA.


In addition to the scientific cargo on board today’s flight, there are some crew care items including fresh apples from an orchard belonging to a SpaceX employee’s family according to SpaceX president Gwynne Shotwell.


“It’s a little bit healthier, I think, than the one that NASA sent last time,” she said, referring to the ice cream sent on the last Dragon spacecraft.


The flight also marks the first time cargo will be carried in the unpressurized trunk of the spacecraft. All of the cargo on the first two flights was carried inside the Dragon capsule, which is designed for human passengers. But the spacecraft also has room for cargo in the cylindrical section beneath the Dragon. On this flight a pair of grapple bars that will be used on the ISS are being carried in the unpressurized section.


In addition to a few firsts, today’s launch marks the last time SpaceX plans on using the first version of its Falcon 9 rocket. Beginning this fall, the launch company plans on using v1.1 of the Falcon 9 with upgraded Merlin engines which will be arranged in a circular pattern rather than the 3-by-3 grid used on v1.0.


Today’s rocket is familiar to Wired readers as it was being built in the SpaceX factory when we visited last spring, and was undergoing testing at the company’s testing facility in Texas when we watched the new Merlin engines being tested last summer. Right now the Falcon 9 and Dragon capsule are not used again, but SpaceX plans to use the hardware for multiple flights in the future.


Unlike the previous two flights to station, which took more than a day because of the phasing between launch and the orbit of the ISS, NASA expects Dragon to dock with the station about 20 hours after liftoff.


There are six astronauts on board the ISS right now, but three of them will return to earth aboard a Russian Soyuz capsule while the Dragon is on station. The SpaceX capsule is scheduled to return itself with more than a ton of cargo on March 25.

Good Eggs Aims to Be the Amazon of Local Food



Good Eggs, which launched last summer as the Etsy of local food, is expanding in a bid to become the Amazon of local food.


The San Francisco-based company launched a new web platform Thursday that lets users select items from local vendors and farmers and combine them in a single order ready for delivery or pickup. That’s transforming Good Eggs from a web stand for multiple vendors to a central hub for purchasing and delivering local food.


“We actually had the inventory for an awesome grocery store, but the missing piece was some kind of central distribution, some way for you place an order across all of these vendors and get a single pickup or delivery,” co-founder Rob Spiro told Wired. “We were experimenting with offices and pickup spots…. The model we found working well was very operational. You end up getting into the logistics game to provide a high quality of service.”


Unlike the traditional CSA (community-supported agriculture) deliveries, Good Eggs lets you customize what you want, to include specific amounts of fruits and veggies, fresh fish, prepared food, baked goods and more. You still pick from what’s in season, but if you hate potatoes, you don’t get potatoes.



To support its newfound operation, Good Eggs is moving into a giant warehouse where it can aggregate all of its vendors’ product and put together its made-to-order boxes of food. Spiro says that they’ve been running test routes throughout the San Francisco Bay Area to figure out which are most efficient, and naturally, the former Googler says that all routes are “optimized algorithmically.”


Delivery does, however, cost an extra $4, whereas pickups at various locations (there are seven in San Francisco) are free.


Unlike Farmigo, another online food startup, Good Eggs caters to the individual rather than the community. Farmigo CEO Benzi Ronen told Wired in December that his company opted out of home delivery because of high costs. Good Eggs’ Spiro says that isn’t so much a concern for him.


“We’re taking the challenge head on,” Spiro said. “We have all these producers already running their businesses through Good Eggs…. You place your orders, it goes directly to the producer, then it goes to this one warehouse…. The long-term goal is to build out hubs in hundreds of areas.”


Good Eggs is already in the process of signing vendors up in Brooklyn, New York City, and plans to expand to several other cities.

Private Plan to Send Humans to Mars in 2018 Might Not Be So Crazy



An ambitious private manned mission to Mars aims to launch a two-person crew to fly around the Red Planet and return to Earth in 501 days, starting in January 2018.


This bold undertaking is planned by the Inspiration Mars Foundation, a non-profit company founded by millionaire and space tourist Dennis Tito that was officially unveiled on Feb. 27 after early details leaked. Though the spacecraft would not land humans on Mars or even put them in orbit, it would bring people within a few hundred kilometers of the Martian surface — roughly the same distance between the International Space Station and Earth — and represent a major milestone in human spaceflight. If successful, the mission would go down in history as the first time a private company accomplished something government agencies were unable to do in space.


The mission is extremely ambitious, well beyond anything previously accomplished by the private sector and it faces plenty of obstacles. The company has an aggressive schedule to keep if it wants to hit its 2018 mark and needs to make sure the necessary technology is developed and well-tested. Despite its deep-pocketed backer, the mission has nowhere near the funding it needs to launch and will require raising greater sums than have ever been done for a private space endeavor. Its designers also need to figure out exactly how to keep the crew healthy, both physically and psychologically, for the 501-day duration of the flight as they face dangers from radiation, bone and muscle loss, fatigue, and depression. Mission designers will have to ensure they can get the crew safely to the ground when the capsule returns to Earth at a screaming 30,000 mph.


Yet despite these hurdles, of all the bold announcements from private spaceflight companies in recent years, this one seems the most achievable.


“The reason this entire thing is possible is because it’s actually a very simple mission,” said Jane Poynter, president of the Paragon Space Development Corporation, which makes life-support systems and has partnered with Inspiration Mars. “We’re not trying to land, we’re going to fly by and we’re using extant technologies that NASA and the space industry have been developing for years.”


Inspiration Mars isn’t looking to sell a product in an unknown market, like the asteroid-mining Planetary Resources or the national-moon-ferrying Golden Spike Company, and doesn’t have incredibly aspirational aims, like the planet-colonizing Mars One. It hopes to undertake a straightforward mission that could spur innovation, inspire young scientists and engineers, and move human spaceflight forward.


“You have to have a reasonable degree of skepticism and realism,” said Taber MacCallum, who co-founded Paragon with Poynter (and is also her husband). “We might run into some insurmountable obstacle 18 months in. But with proper engineering, support, and a good mess of luck, we could see this done.”


Now all they have to do is actually fly to Mars.




As currently outlined, the Inspiration Mars mission would be departing on what’s known as a “fast free return trajectory,” which both minimizes the amount of time spent in space and the amount of fuel required. A spacecraft would fire its rockets for a single burn to set off to Mars, make a few course corrections on the way, circumnavigate the Red Planet, and then slingshot back home using Mars’ gravity, negating the need for another burn. Because of the positions of Earth and Mars, opportunities for such quick flybys happen only every 15 years and, if they miss the 2018 deadline, the next chance won’t come until 2031.


Paragon estimates that the mission would need to launch a 10-ton spacecraft with roughly 33 cubic meters of volume, equivalent to the space in the back of a large moving van. About half that volume would be taken up with water tanks, food, and life support, leaving a cramped living space with an area barely bigger than a parking space. That means putting two people in a room for 1.4 years that’s probably smaller than your bathroom.


The crew would process urine and flush water to recycle about 75 percent of it as drinkable water. They would carry the bare minimum of personal provisions, such as clothing and hygiene items. An initial feasibility study co-authored by Poynter, MacCallum, Dennis Tito, and others didn’t make allowances for privacy, separate sleeping quarters, or even showers (just sponge baths) in the habitat, but it remains to be seen how these ideas would evolve for a real mission.


No existing launch vehicle is large enough to get such a mass into space, though SpaceX plans to have its Falcon Heavy rocket ready within a few years. If SpaceX is unable to meet that deadline, the mission could use two smaller existing launch vehicles, one to bring the tank carrying the rocket engines and necessary fuel and another to launch the crew habitat, which complicates the mission and could make it more expensive.


The number one danger during the journey will be radiation. Whether charged particles streaming from the sun or galactic cosmic rays accelerated by distant sources, space is chock full of radiation. Humans on Earth are protected from this fallout by our magnetic field, which also shields astronauts on the ISS. But out in deep space, the crew of a 500-day trip would be exposed to total radiation roughly equal to the dose an astronaut that flew five or six times to the ISS would expect to receive over their career.


Among other things, radiation damages DNA thereby raising the risk of cancer, and lowers blood cell counts. The effect would be like smoking a pack of cigarettes a day during the whole mission, MacCallum said.


The most severe event to watch out for would be a solar flare or mass ejection, where the roiling surface of the sun produces a burst of charged particles and radiation. If exposed to such an occurrence, a crew might experience nausea, vomiting, blistering, and potentially death. Apollo astronauts were spared a potentially fatal flare in 1972 that occurred between Apollo 16 and 17 but the Inspiration Mars mission would be out in space for a long time, raising the odds of getting hit.


Solar particle events like these happen randomly, though in 2018 the sun will be closer to the minimum part of its activity cycle, lessening the chances of a large event. In the case of a major event, sun-observing satellites would provide some warning and the crew could retire to a storm shelter built from vehicle hardware. But a large event or even several smaller ones could weaken astronauts’ immune systems, said radiobiologist Ann Kennedy of the University of Pennsylvania, who works on the effects of radiation for the National Space Biomedical Research Institute.


With the sun at minimum the crew would be exposed to a higher rate of galactic cosmic rays than normal, and the chronic low-dose of ionizing radiation “can not be shielded against with current technology,” said radiation physicist Jeff Chancellor, also of the NSBRI.


Even surrounding the spacecraft with a huge, thick shield, something like five or six times what the ISS has, would not significantly lower galactic cosmic ray exposure, he added. In fact the more shielding you have, the worse, because the charged particles can interact with molecules in the material to produce further harmful radiation.


The crew can help counteract some of the radiation’s effects with drugs for nausea and vomiting and pills or supplements to provide the daily recommended doses of vitamins.


“My gut feeling is there’s a good chance they can do this mission, but there’s a lot left to be seen,” Chancellor said. Space travel is always risky, he added, though there is hope that further research can provide a crew with effective radiation countermeasures before 2018.


Beyond radiation, the main biomedical problem will be muscle and bone deterioration, which occurs to the human body during extended stays in microgravity. To counteract this, Poynter said it would be of the utmost importance for the crew to have an exercise machine that they use daily for several hours.

Stuxnet Missing Link Found, Resolves Some Mysteries Around the Cyberweapon



As Iran met in Kazakhstan this week with members of the UN Security Council to discuss its nuclear program, researchers announced that a new variant of the sophisticated cyberweapon known as Stuxnet had been found, which predates other known versions of the malicious code that were reportedly unleashed by the U.S. and Israel several years ago in an attempt to sabotage Iran’s nuclear program.


The new variant was designed for a different kind of attack against centrifuges used in Iran’s uranium enrichment program than later versions that were released, according to Symantec, the U.S-based computer security firm that reverse-engineered Stuxnet in 2010 and also found the latest variant.


The new variant appears to have been released in 2007, two years earlier than other variants of the code were released, indicating that Stuxnet was active much earlier than previously known. A command-and-control server used with the malware was registered even earlier than this, on Nov. 3, 2005.


Like three later versions of Stuxnet that were released in the wild in 2009 and 2010, this one was designed to attack Siemens PLCs used in Iran’s uranium enrichment program in Natanz.


But instead of changing the speed of spinning centrifuges controlled by the PLCs, as those later versions did, this one focused on sabotaging the operation of valves controlling the flow of uranium hexaflouride gas into the centrifuges and cascades — the structure that connects multiple centrifuges together so that the gas can pass between them during the enrichment process. The malware’s goal was to manipulate the movement of gas in such a way that pressure inside the centrifuges and cascade increased five times the normal operating pressure.


“That would have very dire consequences in a facility,” says Liam O’Murchu, manager of security response operations for Symantec. “Because if pressure goes up, there’s a good chance the gas will turn into a solid state, and that will cause all sorts of damage and imbalances to the centrifuges.”


The new finding, described in a paper released by Symantec on Tuesday (.pdf), resolves a number of longstanding mysteries around a part of the attack code that appeared in the 2009 and 2010 variants of Stuxnet but was incomplete in those variants and had been disabled by the attackers.


The 2009 and 2010 versions of Stuxnet contained two attack sequences that each targeted different models of PLCs made by Siemens being used in Iran’s uranium enrichment plant — the Siemens S7-315 and S7-417 models of PLC.


In these later variants of Stuxnet, however, only the 315 attack code worked. The 417 attack code had been deliberately disabled by the attackers and was also missing important blocks of code that prevented researchers from determining definitively what it was designed to do. As a result, researchers have long guessed that it was used to sabotage valves, but couldn’t say for certain how it affected them. There were also mysteries around why the attack code was disabled — was it disabled because the attackers had failed to finish the code or had they disabled it for some other reason?


The 2007 variant resolves that mystery by making it clear that the 417 attack code had at one time been fully complete and enabled before the attackers disabled it in later versions of the weapon. And because the 2007 variant only contained the 417 attack code — with no code attacking the Siemens 315 PLC — it appears that the attackers disabled the 417 code in later versions because they wanted to change their tactics, dropping their focus on sabotaging the valves in order to focus instead on sabotaging the spinning centrifuges.

Air Force to Stealth Fighter Pilots: Get Used to Coughing Fits



The Air Force has some bad news for the pilots of its F-22 Raptor stealth fighters: Your planes are going to make you feel crappy and there’s not much anyone can do about it. And the message to the maintainers of the radar-evading jet is even more depressing. Any illness they feel from working around the Raptor is apparently all in their heads, according to the Air Force.


Those admissions, buried in newly released Congressional records, represent the latest twist in the years-long saga of the F-22′s faulty oxygen system, which since at least 2008 has been choking pilots, leading to confusion, memory loss and blackouts — combined known as hypoxia — that may have contributed to at least one fatal crash. Ground crews have also reported growing sick while working around F-22s whose engines are running.


The Air Force claims its has a handle on the in-flight blackouts. All 180 or so F-22s are having faulty filters removed and new backup oxygen generators installed. There have also been changes to the G-suits pilots wear. But the Air Force says the alterations won’t do anything to fix the so-called “Raptor cough,” a chronic condition afflicting almost all F-22 pilots.


The coughing — which, to be clear, is a totally separate issue from hypoxia — is due to a condition known as “acceleration atelectasis,” Maj. Gen. Charles Lyon, who headed the Air Force’s Raptor investigation, wrote in response to questions submitted following a September testimony before a House subcommittee. “Acceleration atelectasis results from pilots breathing high concentrations of oxygen (above 60 percent) while wearing anti-G trousers, and exposure to G-forces,” Lyon explained.


Maj. Jeremy Gordon, a Virginia Raptor flier who blew the whistle on the Air Force last year, described a typical room full of F-22 pilots where “the vast majority will be coughing a lot of the time.” One Air Force widow claimed her F-22 pilot husband’s coughing contributed to his suicide.


The coughing, Lyon continued, results from the closure of the lungs’ alveoli as oxygen-rich air is absorbed, leaving insufficient gas such as nitrogen behind to keep the alveoli open. “The normal physiologic response to re-open the alveoli is to cough,” Lyon wrote adding that an F–22 feeds its pilot higher concentrations of oxygen compared to other jets. Air Force spokesman Lt. Col. Tadd Sholtis told ABC News that the Raptor’s extreme performance — flying higher and faster than most planes — could also exacerbate the cough.


“The Air Force will continue to explore further potential causes through long term breathing air analysis and human systems integration efforts,” Lyon wrote. But he offered no solution to the condition. Apparently, from the Air Force’s point of view, coughing is the cost of sitting the world’s most high-tech fighter cockpit.


With regard to the maintainers who reported symptoms alongside the oxygen-deprived F-22 pilots, Lyon wrote that the Air Force conducted extensive testing and found no evidence that the ground crews were actually sick. “None of the ground incident aircraft cockpit testing revealed anything approaching a remarkable health guidance value,” Lyon explained. “None of the maintainer blood, breath or urine samples indicated anything remarkable.”


Lyon wrote that the Air Force has ruled out any adverse health effects from toxic fluid leaks, hazardous particles from the Raptor’s stealth coating and the possible impact of breathing the F-22′s engine exhaust. If the maintainers really were sick, as they claimed, the Air Force is “confident that factors other than the life support system or the aircraft caused the ground incidents,” Lyon wrote.


The F-22, arguably the most capable jet fighting in the world, is the mainstay of the Air Force’s frontline fleet and has even gotten more money, even while the rest of the military braces for impending budget cuts. Raptor pilots and ground crews shoulder a large part of the burden of deploying American power in the sky. The flying branch’s brass seem to believe coughing, and possibly imaginary illness on the ground, are just part of the job.

That Syncing Feeling



“Smart, or stylish?” That’s the question facing casual watch aficionados looking for a new, high-tech addition to their collection.

On one hand (er, wrist), you’ve got the Pebble and other smartwatch upstarts, which come with built-in smartphone connectivity, customizable screens, and burgeoning developer communities eager to feed their app ecosystems. They also, by and large, look like uninspired pieces of mass-produced Chinese plastic, and that’s because they are.


On the “stylish” end of the spectrum is … not much. Except this: Citizen’s Eco-Drive Proximity.


The Citizen learns the current time from your phone, and the watch’s hands spin around to the correct positions.


By all outward appearances, the Proximity looks like any another chronograph in a sea of handsome mechanical watches. It has all the features you’d expect, including a 24-hour dial, day and date, perpetual calendar and second time zone. But housed within its slightly oversized 46mm case is a Bluetooth 4.0 radio, so it’s capable of passing data over the new low-energy connectivity standard appearing in newer smartphones, including the iPhone 5 and 4S. And for now, the Promixity is only compatible with those Apple devices.


Initial pairing is relatively easy. After downloading Citizen’s notably low-rent iOS app, you can link the watch to your phone with a few turns and clicks on the crown.


The gee-whiz feature is the automatic time sync that takes place whenever you land in a different time zone. Once connected, the Citizen learns the current time from your phone, and the watch’s hands spin around to the correct positions — a welcome bit of easy magic, considering the initial setup is a tedious finger dance.



The watch can also notify you of incoming communications. Once you’ve configured the mail client (it only supports IMAP accounts), you’ll get notified whenever you get a new e-mail — there’s a slight vibration and the second hand sweeps over to the “mail” tab at the 10-o’clock position. If a phone call comes in, the second hand moves to the 11-o’clock marker. If the Bluetooth connection gets lost because the watch or phone is outside the 30-foot range, you get another vibration and the second hand moves to the “LL” indicator. And really, that’s the extent of the functionality around notifications.


But notable in its absence is the notification I’d like the most: text message alerts. And it’s not something Citizen will soon be rectifying because the dials and hardware aren’t upgradable.


I also experienced frequent connection losses, particularly when attending a press conference with scads of Mi-Fis and tethered smartphones around me. This caused dozens of jarring vibrations both on my wrist and in my pocket, followed by a raft of push notifications on my phone informing me of the issue. Reconnecting is easy (and generally happens automatically), but the lack of stability in certain environments matched with the limited capabilities of the notifications had me forgetting to reconnect and not even worrying about it later on.



But actually, I’m OK with that. I still like the fact that it never needs charging. Even though there aren’t any solar cells visible on the dial, the watch does have them. They’re hidden away beneath the dial, and yet they still work perfectly. And even when its flagship connectivity features aren’t behaving, it’s still a damn handsome watch. It feels solid, and it looks good at the office, out to dinner, or on the weekend — something very few other “smart” watches on the market can claim.


However, those things can be said of almost all of Citizen’s EcoDrive watches. The big distinguishing feature here is the Bluetooth syncing and notifications, and they just don’t work that well.


WIRED A smart watch you won’t be embarrassed to wear. Charges using light. Combines classic styling with cutting-edge connectivity. Subtle notifications keep you informed without dominating your attention.


TIRED Loses Bluetooth connection with disturbing frequency. Limited notification abilities. No text message alerts. Janky iPhone app.

Good Lookin' Out



The other strap-it-on-and-get-rad cameras out there — the GoPros and the Contours and the Ions — are all pretty sick in their own right. But for ease of use, no camera is sicker than Drift Action’s HD Ghost cam.


It has enough capability and pure oomph to keep up with the competition — it captures 1080p at 30fps and 720p at 60fps, and it can talk to your other devices via Wi-Fi — but it also comes stock with features other cams make you pay extra for: an integrated 2-inch color LCD screen; big, meaty navigation buttons on top of the camera; and a wrist-mounted remote control that lets you start and stop recording from up to 30 feet away. The whole thing’s waterproof up to 9 feet, too, so mountain biking through a rainstorm or snowboarding during a whiteout doesn’t require a separate waterproof case.


Now, 1080p at 30fps isn’t the best in class. The best camera for slow-mo footage is the GoPro Hero3 (also $400), which offers double the frame rate at 1080p. And all those additional features — the remote, the LCD screen, the waterproof case — are available in some form or another with other cams, albeit usually at an extra cost. What makes the HD Ghost stand out is how easy to use it is. Thanks to the clearly labeled buttons and the intuitive menu on the LCD screen, I was able to ditch the user guide and still access the majority of the Ghost’s functions.


The wrist-mounted remote is great, too. The controls can be operated with heavy gloves on, and the buttons make changing settings, swapping functions, and checking out the footage you just captured remarkably easy. Colored LED lights on the watch-sized unit let you know what mode the Ghost is in, as well as the camera’s status.



My favorite feature on the Ghost is the on-the-fly video-tagging capability. When it’s in what Drift calls “Flashback mode,” the camera records video on a continuous loop ranging in length from 10 seconds to five minutes. If something sweet happens on your bike ride, you can press a button and save the last minute of footage (or however long), then immediately start a new loop. Not only does this save precious space on your memory card, but it also saves you from having to wade through hours of boring footage to find the good clips.


During my test trip to Squaw Valley in Northern California’s Lake Tahoe area, I never lost footage due to user error (leaving the camera off and thinking it was recording when it wasn’t, which I usually do all the time), and the rotating lens let me mount it just about anywhere without tweaking my angles. I was satisfied with the footage. It was clear and sharp, and I was able to snag the occasional still photo while I was recording video.


Here’s a highlight reel. This string of clips is made up of raw video straight from the camera.





The GoPro Hero and the new Sony Action Cam are still the wearables to beat for image quality and (especially with the GoPro) capturing slo-mo shots. But I can heartily recommend the HD Ghost, especially for those who’d rather get outside and start recording than spend hours digesting a manual to figure out how it works.


WIRED Simple out-of-box use. Battery lasts about three hours. Waterproof to 9 feet without a case. Intuitive smartphone app interface. Awesome remote you can strap to your wrist, or anywhere. Rotating lens lets you position it pretty much anywhere on your body or board and still find acceptable angles. Can capture 11-megapixel stills while shooting video.


TIRED Heavy. Multicolored LED lights aren’t great for us red/green colorblind folks. Pricey — Sony’s camera is less expensive.

Cash-Strapped Army Still Plans on Helping Pakistan Fight Narcotics



The war on terrorism isn’t the only endless war the U.S. is waging. The drug war never went away, it just went overseas — and the U.S. military is lending new support to an effort to stem narcotics in Pakistan.


A series of new solicitations by the Army Corps of Engineers show that even in these cash-strapped times, the U.S. is willing to build new structures, including in major airports, for its Pakistani frenemies to sniff out drug smugglers.


At the southern Pakistani city of Karachi, the Army expects to build a 7,000-square-foot command center right inside Jinnah International Airport. Complete with a “cell/interrogation building,” the new center will help provide “quick-response to constantly evolving narcotics and contraband smuggling tactics.” Among the chief beneficiaries: Pakistan’s “Rummaging and Patrolling Section,” which apparently exists. Cost: up to $2 million.


Then there’s another 28,300-square-foot command center the Army wants to construct in Islamabad. This one will be operated by Pakistan’s DEA-mentored “elite, vetted” Anti-Narcotic Force Special Investigative Cell. At the command center, the Cell will “carry out liaison with international counterparts, compile sensitive drug related intelligence, conduct sophisticated investigations, and plan interdiction operations.” Cost: up to $5 million.



Pakistan is a hub for drug trafficking — not just the narcotics coming in through the opiate breadbasket next door in Afghanistan, but precursor chemicals like acetic anhydride, ephedrine and pseudoephedrine. The U.S. interest in assisting Pakistan hunt narcotics dealers is less clear, particularly as the military lights its hair on fire warning about the disastrous impact of automatic spending cuts looming on March 1. To scare Congress into reversing the cuts, the Army this week released a state-by-state breakdown of what a loss of $18 billion this year from its operations account would look like.


Yet counternarcotics is one of the most lucrative sources of government contracting, and one that ties the war on drugs into the war on terrorism. A Pentagon bureau known as the Counter Narco-Terrorism Program Office is staffing up in Kabul to run Afghanistan’s drug war. And in 2011, it disbursed a pot of money worth more than $3 billion for security contractors everywhere from Mexico to Azerbaijan, making it one of the most lucrative security-contracting agencies in the entire U.S. government. It’ll be a long time before the U.S. military gets out of the south-Asian anti-drug game, whatever the budget situation might be.

Turkish Soccer Fans Roar Loudly Enough to Damage Your Ears



ISTANBUL, Turkey — The Turks, who love football as much as anyone, have the loudest fans on earth.


The 51,998 people packed into Turk Telekon Arena, home to the Galatasaray football club, let out a 131.76-decibel roar during a match against Fenerbahçe two years ago, enough to secure a spot in the Guinness book of records. That’s louder than The Who during their 126-decibel gig in London in 1976, and louder even than standing behind a fighter jet at takeoff.


They haven’t gotten any quieter.


Check out a Galatasaray game and you’ll have no doubt how much the Turks love the sport Americans call soccer. Oh sure, their three biggest clubs, Galatasaray, Fenerbahçe and Beskitas, may not be the most successful, but they boast millions of followers.


Millions of very, very loud followers. The fans, profiled in Ford’s Fantastic World of Football documentary series, are passionate about the beautiful game, and want everyone to know it.


They pack the stands, screaming as if the the match will be won or lost on noise alone. I brought along a decibel meter for a recent match and the din hit 97 decibels — about as loud as a jackhammer, and enough to cause some serious hearing loss at sustained levels. It was modest compared to that derby game against Fenerbahçe, but enough to make your hair stand on end.


So even if the team can’t guarantee the right result, one thing Galatasaray’s fans can guarantee is an incredible — and incredibly loud mdash; atmosphere.

The 'One' Is a Huge Step Forward for HTC



HTC’s new flagship smartphone, the One, is an impressive bit of hardware and a big step forward for the company in three significant ways.


The One is a top-notch, beautifully designed handset packed with the best specs and a ton of compelling features. It also runs a unique, fresh take on Google’s Android operating system. And it’s available in exactly the same configuration across the three major U.S. carriers. This is the phone that could close the gap between HTC’s flagship and those from Apple and Samsung.


We spent a couple of hours with the One before its big unveiling in New York today, and were thoroughly impressed by the luxurious materials used on the handset, the expert build quality holding it all together, and a slew of thoughtfully crafted software features. Although the phone carries the branding established last year with the One X, One S, and other HTC phones, the One amounts to a reboot of the company’s vision for Android. The One X, HTC’s previous flagship, won critical praise, but as an AT&T exclusive it failed to generate the sales the company had hoped for.


“We think about the One X and we think ‘Wow, it was big, and it was one of the best phones we’ve ever done,’” Scott Croyle, HTC’s vice president of design, said. “But if I were to compare it to, say, other stuff that was out there, I wouldn’t say it was a step change different.”


The company set out to build a phone that could surpass, not just meet, the performance and quality of the Apple iPhone 5 and Samsung Galaxy SIII. So it put a huge effort into nailing the Sense user interface, packing the phone with the best tech and broadening its reach across carriers. Sense 4, the previous generation of HTC’s Android customization, has been thrown out. Every aspect of Sense has been rethought and redesigned. The result is a slick, clean user interface, full of artful icons that match the flat, understated look Google has been trying to push with its own stock version of Android. And there’s a focus in the new Sense on making things that users commonly do easier and more intuitive — such as sifting through social media and news apps, or snapping photos and video.


“I think we came to this recognition that, ‘Wow, there are these two other companies that are going to spend a lot more money than HTC,’” Croyle said. “This is the reality of the business. They have much deeper pockets and they can carpet bomb the industry and they have a tremendous amount of inertia there, particularly with Apple in the U.S. So, for the One, we really had to get it right, we really had to just go for it.”


While it’s easy to see the chamfered edges found on the One and think of the iPhone 5, the One is far from a copycat product. It has a massive — and gorgeous — 4.7-inch 1080p display with a pixel density of 468 pixels per inch. As with nearly every flagship phone out there nowadays, pixels are indiscernible on the One’s generous display. Colors look vivid and crisp as well.


The touchscreen dominates the front of the One, with aluminum capping each end. Rows of pinholes are machined into each strip of aluminum, serving as pathways for sound coming from a set of dual front-facing speakers. Every phone speaker we’ve ever heard has sounded like hell. While the One won’t replace your Jambox anytime soon, its onboard speakers sound immensely better than anything we’ve heard from a phone. Inside, the One features a 1.7GHz, quad-core Qualcomm Snapdragon CPU, 2GB of RAM, and NFC chip, Bluetooth 4.0 and connectivity to both HSPA and LTE networks.


Everything is packed into a sleek, aluminum unibody — shipping in either silver or black — that features a subtly curved back with inlaid antennas. The One weighs 5.04 ounces, and is just 0.36 inches thick.


The One will also sports a beefed up camera, with a ton of photo and video features — which are so plentiful we’ve written a separate story focusing on the One’s camera.



Along with all new hardware, HTC is using the One to introduce an all new take on Android. Sense 4, HTC’s last skin, was among the best versions of Google’s mobile OS thanks to its simplicity and gimmick-free implementation. The latest version — now just called Sense — brings users from a lock screen to a new Flipboard-like app called BlinkFeed, which displays a feed of information, stories, photos and video from various sources of your choosing. HTC has worked in integration with a few news outlets, so news stories by topic or by outlet can show up in your BlinkFeed. And the app can be connected to Twitter, Facebook, Flickr and other social networks as well.


See a news story you’re interested in reading? Just tap the tile in your feed and you’re taken to a view that shows the story and its accompanying artwork in a presentation that makes reading clean and easy — again, very much like Flipboard, Pocket, Pulse and other “read it later” services. Tap a tweet or post from Facebook you’ll be launched into that corresponding social network’s Android app. You can even set up BlinkFeed to pipe in your photos and videos. Everything is displayed in reverse chronological order, just like your Twitter timeline, Facebook feed and everything else that’s sorted online.


While BlinkFeed is a pre-installed app, it’s also the default view any One user will see once they unlock their phone. If you want to get to a traditional Android homescreen view — with apps, widgets and folders of apps — just swipe in from the right on BlinkFeed and Android as you know it will appear.


“If you want regular Android, it’s there,” Croyle said. “But, everybody’s snacking on information, whether it’s from their social networks or some news source that they’re just interested in. So [BlinkFeed] really is geared around that recognition of how people are actually using their phones.”


AT&T, Sprint and T-Mobile will sell the One, along with many smaller regional telecom companies. The significance of this can’t be overstated. Currently, only Apple’s iPhone and Samsung’s Galaxy S III are offered as widely. The iPhone is sold through AT&T, Sprint and Verizion — and it’s on it’s way to T-Mobile. The S III is sold by all four of the nation’s top carriers. All too often, a great phone, like last year’s One X, was confined to a limited audience due to carriers wanting exclusive rights to phones.


The fact that the One is joining it’s biggest rivals in a new paradigm that bucks the idea of exclusive phones is a good thing for HTC — because they get to sell their best device in more places — and consumers — because you have more choice when you go to buy your next phone.

<cite>Halo</cite> Creator Unveils Its Next Masterpiece, a Persistent Online World



BELLEVUE, Washington — Destiny, the new game from the creator of Halo, isn’t just another shooter. It’s a persistent online multiplayer adventure, designed on a galactic scale, that wants to become your new life.


“It isn’t a game,” went the oft-heard tagline at a preview event on Wednesday. “It’s a world where the most important stories are told by the players, not written by the developers.”


This week, Bungie Studios invited the press into its Seattle-area studio to get the first look at Destiny. Although the event was a little short on details — Bungie and Activision didn’t reveal the launch date, handed out concept art instead of screenshots, and dodged most of my questions — it gave an intriguing glimpse at what the creator of Halo believes is the future of shooters.


Bungie was acquired by Microsoft in 2000, and its insanely popular shooter was the killer app that put the original Xbox on the map. Bungie split off from its corporate parent in 2007, and Microsoft produced Halo 4 on its own last year. The development studio partnered up with mega-publisher Activision for its latest project, which was kept mostly secret until now.


Destiny, slated for release on PlayStation 3 and Xbox 360, isn’t exactly an MMO. Activision CEO Eric Hirshberg called it a “shared-world shooter” — multiplayer and online, but something less than massive.


“We’re not doing this just because we have the tech,” Hirshberg said. “We have a great idea, and we’re letting the concept lead the tech.”



Built with new development software created specifically for Destiny, this new game is set in Earth’s solar system and takes place after a mysterious cataclysm wipes out most of humanity. The remaining survivors create a “safe zone” underneath a mysterious alien sphere called “The Traveler.”


The enigmatic sphere imparts players with potent weapons, magic-like powers and defensive technology. Thanks to these gifts, people have begun reclaiming the solar system from alien invaders that moved in while humanity was down.


Bungie fired off a list of design principles that guide Destiny’s creation: Create a world players want to be in. Make it enjoyable by players of all skill levels. Make it enjoyable by people who are “tired, impatient and distracted.” In other words, you don’t have to be loaded for bear and pumped for the firefight of your life every time you log on to Destiny.


After this brief overview, writer/director Joseph Staten used concept art and narration to outline an example of what a typical Destiny player’s experience might be.


Beginning in the “safe zone,” a player would start out from their in-game home and walk into a large common area. From here, the player would be able to explore their surroundings and meet up with friends. Then, they might board their starships and fly to another planet, let’s say Mars, in order to raid territory held by aliens.


During this raid, other real players who traveled to the same zone (like visiting a particular server on an MMO) would be free to come and go as they please. For example, a random participant could simply walk on by. They could stop and observe. Or they could get involved in the fight. In this instance, Staten suggested that a passerby would join the raid and then break off from the group after the spoils were divvied up without any user interface elements to fuss with. Walk away, and it’s done.


Bungie made a point of saying several times over that Destiny will not have any “lobby”-type interfaces, or menus from which to choose from a list of quests. Instead, players will simply immerse themselves in the world and organically choose to participate in whatever activities they stumble upon. Bungie promised solo content, cooperative content, and competitive content, though it provided no further examples of these.


The developer said that by employing very specialized artificial intelligence working entirely behind the scenes, players will encounter other real players who are best suited for them to interact with, based on their experience levels and other factors.


Staten didn’t say how many players would be able to exist in the world at the same time, but said that characters will be placed in proximity to each other based on very specific criteria, not simply to “fill the world up.”







Bungie showed off three distinct character classes throughout the day’s presentations: Hunter, Titan and Warlock. Although no differences were outlined between them apart from the Warlock being able to use a kind of techno-magic, the developer was keen to emphasize the idea that each character in Destiny would be highly customized and unique, and will grow with the player over an extended period of time.


While many games make the same promise, Destiny’s vision of “an extended period of time” isn’t 100 hours. It’s more like 10 years.


Bungie’s plan is for the Destiny story to unfold gradually over the course of 10 “books,” each with a beginning, middle and end. Through this will run an overarching story intended to span the entire decade’s worth of games, although like many other topics covered during the day, Bungie gave little detail about how this will work.


The developer spent a lot of time emphasizing its claim that no game has been made at this scale before. Bungie says it has a whopping 350 in-house developers working on Destiny.


Senior graphics architect Hao Chen gave examples of the sort of impenetrable mathematics formulas that allow Bungie to craft environments and worlds at a speed that it claims was previously impossible.


Bungie’s malleable team system was also said to increase its output. With the ability to co-locate designers, artists, and engineers at any time, Bungie says it can go through exceptionally rapid on-the-spot iteration and improvement for each facet of the game.


Apart from highly improved technology and the basic concept of humanity taking back the solar system, there’s just not a lot of hard information on Destiny at the moment. One thing that was made quite clear is that the game will not be subscription-based. Every presenter was clear in stating that players will not pay a monthly fee to participate in this persistent world.


While fees may not be required, a constant connection to the Internet will be. Since the core concept of Destiny is exploring a world that exists outside of the player’s console and is populated by real people at all times, it “will need to be connected in order for someone to play,” said Bungie chief operating officer Pete Parsons.


Representatives from both Bungie and Activision gave vague answers when Wired pressed for further details, often stating that they “were not ready” to discuss specifics. Whether that means those things are still being kept from the press, or whether they have not yet been determined by the development team, was unclear.


Questions currently unanswered: How will players communicate? How will players interact with each other outside of combat? What content exists in the non-combat “safe zones”? Subscriptions may be out, but what about in-app purchases? Will player versus player combat be available? Will the game ship on a disc or be download only? Will its persistent world allow Xbox and PlayStation gamers to play together? What content and interactions will be possible via smartphones and tablets (which Bungie alluded to)? Will the fancy new tools be licensed to other developers?


And so on.


For now, Bungie is asking us to take it for granted that it will execute on a bold 10-year plan for a very different sort of shooter. In the history of the always-changing gaming industry, no one’s ever been able to pull off a 10-year plan for anything. Can Bungie do it?


Hey… they made Halo, right?

The Quirky World of Competitive Snow Carving Comes to California



The weekend at Northstar ski resort in Truckee, California, is beautiful, sunny, and in the 30s. For eight teams of snow carvers from around the world, though, it’s terrible — the melty snow is sloppy, hard to carve, and even dangerous.

Teams of three from Finland, Japan, Germany, Canada, and the U.S. were selected from more than 40 applicants for the inaugural Carve Tahoe, a five-day competition to hew works of art from 14-foot-high, 20-ton blocks of snow. But despite the bad snow, the teams rely on decades of experience, handcrafted tools, and creative techniques to fashion their massive sculptures. The team members are sculptors and artists and designers, but also doctors and lawyers. Though they spend weeks each year carving, nobody makes a living doing it.


“Everyone seems to have their own method of doing things,” says Team Wisconsin’s Mark Hargarten. “It’s amazing how different they are.”


The Wisconsin team uses a grid system for their carving — a Native American wearing an eagle costume, its feathers turning to flames, called “Dance of the Firebird.” The polyurethane model they built is scaled so 1/2 inch equals one foot on the finished snow sculpture. They cut a copy of the model in four, and covered each section with clay, sectioned in 1/2 inch increments. They etch corresponding lines in the snow, one foot to a side, and they peel off one piece of clay, carve the part of the sculpture they can see, and move on to the next.


“You never get lost using the method,” says Dan Ingebrigtson, a professional sculptor from Milwaukee. “Three or four guys can work from different angles, and meet in the middle.”


Wisconsin’s got several other strategies behind their carving as well. From the south, it looks like they haven’t even started; they left the southern side of the block intact to protect the rest of it from the sun, and the wall has been decimated by the heat. More than 20 percent of its thickness has melted by Sunday night, three days in. After the sun goes down, the team is hollowing out the interior of the structure, so it will freeze faster overnight.


Other teams are relying on nighttime freezing as well. A team partly from the U.S. and partly from Canada carves spires from blocks they removed from the sculpture, and plans to attach them to the top of their sculpture, “The Stand,” which incorporates four interwoven trees. They’ll use melty snow pulled from the middle of the block right when the sun goes down to cement the tops onto the trees, says team member Bob Fulks from the top of a stepladder as he cuts away at the sculpture with an ice chisel.


Fulks’ team is leaving Tahoe after the competition to go straight to Whitehorse, in the Yukon, for another competition, where he anticipates no problems with warm weather.


“It’s a good gig, you can travel all over the world doing it,” he says. “You go around and see the same people.”


Many of the carvers know each other from previous competitions.


“We’ve sculpted with almost everybody here before,” says Team Idaho-Dunham’s Mariah Dunham, who is working on “Sweet House (of Madness)” with her mother, Barb. The creation is a beehive, with the south side as the exterior, and the north side (intentionally placed out of the sun) as a representation of the comb, including hexagonal holds that perforate all the way to the hollow interior.


Though Carve Tahoe is new, snow carving is not. Many of the sculptors have been at it for more than 20 years, traveling around the world and meeting and competing against many of the same people — though each competition demands unique new designs from all the sculptors. Kathryn Keown discovered snow carving while Googling something completely different, and decided she wanted to host an international event.


“First we fell in love with the sculptures, then we fell in love with the sculptors,” says Keown, who founded the competition with Hub Strategy, the ad agency where she works.


Keown contacted several ski areas before Northstar, but the resort was on board right away; its owner, Vail Resorts also owns Breckenridge, where one of the biggest and most prestigious snow carving competitions is held.


But Keown wanted to commit to the design of the competition, not just the sculptures. Applicants submitted their designs last summer, and Keown enlisted Lawrence Noble, chair of the School of Fine Art at the Academy of Art University to help choose modern, complex, realist designs. She wanted no artsy, kitschy snowmen.


Then she chose a design-friendly logo and judges. In addition to Noble, the panel of judges features a sushi chef from Northstar, two interior designers, a photographer from nearby Squaw Valley, and Bryan Hyneck, vice president of design at Speck, which makes cases for mobile devices and was one of the event’s sponsors.


“The level of complexity and sophistication in this type of sculpture is just amazing,” says Hyneck, who has judged industrial and graphic design competitions, but never snow carving. “It’s amazing how organic some of the shapes can be.”


As a judge, Hyneck says he’ll focus on the craft and the execution of the sculptures, and how the sculptors use particular techniques to take advantage of the snow’s properties. But he adds that subject matter, point of view, message, and relationship to a theme are all important points as well.


“Anybody that is really going to push the limits of the capabilities of the media is going to get a lot of my attention,” he says.


For some, like the Germans, that means suspending massive structures made completely of snow. Their sculpture, titled “Four Elements”, features four large spires encircled by a tilted disc. Despite a trickle of melted snow dripping off the bottom edge, one — or even two — of the German carvers frequently stand atop the sculpture, using saws or chisels to shape the towers.


Sunday evening, after the sun has gone down and the temperature dropped, Josh Knaggs, bearded, with a cigarette in his mouth, is sitting in the curve made by the largest bear from the Team Idaho-Bonner’s Ferry sculpture, “Endangered Bears.” Wearing a blue event-issued jacket, he’s brushing out the hollow loop made by mama and papa bear.


Three days later, the judges award Knaggs and his team third prize, with Japan’s modern work, “Heart to Heart” coming in second and Germany’s gravity-defying “Four Elements” taking first. The teams disperse, and after a few more sunny days, Northstar tears down the structures before they get too soft and fall — all except the German piece, which can’t bear its own weight and collapses after judging is complete. But the ephemeral nature of the snow is part of what attracts the competitors.


“It’s for the moment, and it’s a beauty all in itself, creating something that’s gonna be disappearing, you know, it’s okay that it disappears,” says Team Truckee’s Ira Kessler. “We are making it for the moment.”

Watch Live: Record-Setting Asteroid Flies by Earth











The day has come for our planet to get a cosmically close visit from asteroid 2012 DA14. The 50-km-diameter space rock will make its closest approach to Earth at 11:24 a.m. PST/ 2:24 p.m. EST, at which point it will be only 27,700 km above the surface, less than one-tenth the Earth-moon distance and well within the orbit of geosynchronous satellites.


Wired will have live feeds from several sources all day long starting at 9 a.m. PST/12 p.m. EST. You can check back with us throughout the day as we update with the latest telescope views from observatories around the world. The first live show (above) is from NASA, which is streaming views from telescopes in Australia and Europe. NASA scientists will provide commentary of the event starting at 11 a.m. PST/ 2 p.m. EST and continuous coverage for several hours.


During peak viewing hours, astronomers in the Middle East and Europe will offer two chances to watch the flyby. The Bareket Observatory in Israel will provide images of the asteroid updating continuously every 30 to 60 seconds from 11 a.m. to 12:30 p.m. PST/2 p.m. to 3:30 p.m. EST. The Virtual Telescope Project will have live images from Italy along with commentary starting at 2 p.m PST/5 p.m. EST.


Once the sun sets in the U.S., several outfits will have feeds of the asteroid as it flies away from the Earth. One feed will come from the Clay Center Observatory in Massachusetts, which will last from 3 p.m. to 1 a.m. PST/6 p.m. to 4 a.m. EST. NASA’s Marshall Space Flight Center in Alabama will stream three hours of asteroid images starting at 6 p.m. PST/9 p.m. EST. And, if you need still more asteroid views, you can tune into two Slooh Space Camera shows, the first at 6 p.m. PST/9 p.m. EST and the second at 9 p.m PST/midnight EST. Slooh’s astronomers Paul Cox and Bob Berman will provide commentary and insight along with Prescott Observatory manager Matt Francis.

The Poisonous Chemistry of Chocolate


In honor of Valentine’s Day, I am posting an updated version of an earlier, favorite piece about the chemistry of chocolate:


The Latin name for the cacao tree – the tropical plant source of all things chocolate – consists of two words packed with candy-loving scientific exuberance. Theobroma cacao. It derives from the Greek words for god (theo) and food (brosi), roughly translating to “food of the gods”.


Well, sure you say. Obviously. This is chocolate, after all. But it’s not the heavenly reputation of chocolate that I’m here to talk about.  I’m instead trying to explain why the most potent chemical compound in chocolate – a plant alkaloid, slightly bitter in taste, surprisingly poisonous in some species – is called theobromine.


And while chocolate, as a whole, has a wonderfully seductive chemistry, this poison-obsessed blog will remain, well, obsessed. Today’s obsession is inspired by the fact that every Valentine’s season, in addition to stories about love and lace, newspapers run cautionary candy tales.  Or as a warning issued by the Dog Help Network yesterday noted: “Valentine’s Day is the single biggest day on which dogs are taken to emergency rooms because of ingested chocolate.”


And while we can certainly debate whether the fat and sugar in candy are good for dogs, what this warning refers to is ingested theobromine.


Theobromine is an alkaloid, which is basically another way of saying that it’s part of the everyday chemistry of the plant world. Plant alkaloids are nitrogen-based, typically with with flourishes of carbon, hydrogen and occasionally other atoms such as oxygen. The recipe (or as chemists like to say, formula) for theobromine is seven carbon atoms, eight of hydrogen, four of nitrogen and two of oxygen.


And while this may sound like a recipe for the routine, alkaloids are anything but. The first plant alkaloid isolated (in 1804) was morphine from the flowering poppy. Other notable examples include cocaine (1860), nicotine (1828), caffeine (1820), strychnine (1818) and a host of pharmaceuticals including the anticancer drug Vincristine; the blood pressure medication, reserpine; and the antimalarial compound, quinine.


By this standard, theobromine discovered in cacao beans in 1841, might sound to you like a basic wuss of the alkaloid family. It’s mostly known as a mild stimulant in humans; it contributes (along with caffeine and a few other compounds) to that famed lift that people get from eating chocolate.



There is some evidence that if people get carried away with chocolate consumption, of course, theobromine will make them a little twitchy. According to the National Hazardous Substances Database: “It has been stated that “in large doses” theobromine may cause nausea and anorexia and that daily intake of 50-100 g cocoa (0.8-1.5 g theobromine) by humans has been associated with sweating, trembling and severe headache.” Occasionally, people (mostly the elderly) have needed hospital treatment for a theobromine reaction.


But if one looks at LD50 values, it’s obvious that the alkaloid is far more threatening to other species. LD50 is shorthand for “Lethal Dose-50 percent”. In other words, its basically the dose that will kill 50 percent of a given population. It is  usually calculated in milligrams of poison per kilograms of body weight. The theobromine LD50is about 1000 mg/kg in humans. But for cats it’s 200 mg/kg and for dogs it’s 300 mg/kg – in other words, we aren’t the species most at risk here.


The risk varies, of course, by animal size and shape and breed. A few years ago, in fact, National Geographic published a fascinating interactive chart so that pet owners could search out the individual risk. The chart focuses on dogs because they are more likely than cats to eat something sweet. And it notes that theobromine is more concentrated in dark chocolates making them more dangerous than milk or “white” chocolate. The dark chocolate effects are so acute for canines, that the alkaloid has been tested with some success as a means of controlling coyote populations. (Interestingly, rats and mice are much less affected; their theobromine LD50 is much more like that found in humans.)


The different toxicities have to do with the way different species metabolize the alkaloid; humans process it much more efficiently than canines. And in small amounts, theobromine’s effects can make it medically useful. But even here, it shows complexity. It increases heart rate and at the same time it dilates blood vessels, acting to bring down blood pressure. It can also open up airways and is under study as a cough medication. It stimulates urine production and is considered a diuretic. It interacts with the central nervous system (although not as effectively as caffeine).


At toxic levels – in a characteristic dog death, for instance – all of this adds up acute nausea, convulsions, internal bleeding and often lethal over-stimulation of the heart. “See a vet immediately” is the message of one cautionary post, titled Toxic Chocolate. Another column, written by a vet, suggests rather hopefully that an evening walk is far more romantic and less likely to feature pet vomit (which she describes in revoltingly foamy detail).


We had that same foamy experience in our household  one Christmas  when our dog discovered our son’s holiday stash. We all survived but the humans in the house are a lot more careful about where they leave their chocolate. And this Valentine’s Day, we’re sticking to champagne. Sure, ethanol is also a poison in its own right. But that’s a different story.

Navy: No New Weapons System on Our Future Carrier-Based Drone



The admiral in charge of the Navy’s drone development says there will be “no new weapons development program” for the drone the Navy wants to operate on an aircraft carrier.


Rear Adm. Matthias Winter told a drone-industry conference on Wednesday that the Navy isn’t going to design any new weapons for its future Unmanned Carrier Launched Airborne Surveillance and Strike System, or UCLASS. The futuristic drone, which the Navy wants to take off and land from an aircraft carrier at the click of a mouse, will use weapons already in the magazines of aircraft carriers.


In other words, even though the UCLASS will likely be the most advanced drone in the U.S. fleet, its weapons — most likely missiles — are going to be familiar.


Very little has been public about the weapons that the UCLASS will carry. Winter, a senior official with the Navy’s aviation branch, indicated that’s because little has been decided about them. The demonstration model built for UCLASS, the batwing-shaped X-47B, will “never carry a weapon,” Winter said in response to a Danger Room question about UCLASS’ weapons systems.


The Navy intends to issue a solicitation to defense companies as early as this year for industry to compete for what UCLASS should actually look like. Winter said the Navy plans on a “dialog” with defense companies about the weapons systems aboard the carrier drone, and how it integrates into the other systems on the drone, rather than a set Navy dictate. “There will be strike capability as part of this solicitation,” Winter said, without elaboration. “The specifics will be in the trade space.”



Ruling out weapons aboard the X-47B demonstrator raises an issue for UCLASS. Since the demonstrator’s tests, currently occurring at Patuxent River, Maryland, are supposed to inform the specifications for UCLASS, how can the Navy learn anything about operating UCLASS’ weapons systems and integrating them with the other systems on the drone?


Winter said that the Navy staff is talking with fleet commanders to understand the “best strike capability that the UCLASS should carry.”


“I will tell you that it will be something that, from a munitions perspective, it will be something that’s already been certified … that is carried in our magazines on our aircraft carriers,” Winter continued. “There is no new weapons development program associated with UCLASS, and that strike capability will be organic to the UCLASS system.”


The point of the program is hardly just lethality. UCLASS is supposed to provide persistent surveillance, intelligence and reconnaissance for an aircraft carrier battle group as well. Testing is underway with the X-47B to understand how the futuristic drone will operate alongside a deck crew used to shepherding human pilots, and alongside manned Navy jets in the air. The Navy also wants a common operating architecture that will allow it to control its multiple drones and robots — including UCLASS and, Winter said, also its Tomahawk missiles that are already kind of drone-like — and seamlessly share data.


By the spring, the Navy intends to launch the X-47B from an aircraft carrier out at sea for the first time. That’s meant to keep the Navy on track to getting its follow-on, the UCLASS, onto a carrier and into the fleet by 2019.

Check the comments section on any tech blog: People love to hate Apple. They love to hate Microsoft. And Facebook. Each of these companies has spawned a parallel online hater community.


But Amazon? Not so much.


The Amazon haters are no doubt out there. But I contend that the intensity of that hatred just isn’t as high.


Top 5 companies by reputation


Backing me up on that is a new survey from Harris Interactive (HPOL) that found the general public respects Amazon more than any other U.S. corporation.


The marketing firm polled 19,000 U.S. residents in deep detail to find out how they felt about the country’s 60 “most visible” companies. For the first time in the “reputation quotient” poll’s 14-year history, Amazon came out on top.


Rounding out the top five were Apple, Disney, Google and Johnson & Johnson. (Apple’s number-two ranking shows great hate does not exclude great love.)


The poll — independently funded by Harris — broke down reputation into six main categories. Amazon trounced the competition in the category of “emotional appeal,” beating second-place Disney by five points on a 100-point scale – which seems bizarre considering the only contact most of us ever have with Amazon is via a cardboard box.


“Amazon is predominantly a virtual company where you don’t get to see the people. You don’t see brick and mortar,” says Robert Fronk, executive vice-president of reputation management at Harris. “For them to first of all have the highest reputation, but more importantly to be the company with far and away the highest emotional appeal, is amazing.” Harris defines emotional appeal as trust, admiration and respect, not whether you get weepy when your package arrives.


Amazon also topped the products and services category, which Fronk attributed not so much to Amazon-branded products like the Kindle, but the millions of other products it brings together and sells. Even Amazon’s customer service, which is sometimes criticized for being opaque and inaccessible, gets very high marks in the Harris survey from customers and non-customers alike.


Amazon is also helped in the overall survey results by what Fronk describes as the tech industry bump: Americans simply admire the tech industry more than any other. (In what other industry, he says, can a company take a swing at a product and miss and still get credit for taking a chance?) Industries at the bottom of the reputation rankings were tobacco in dead last, followed by government and banking.


Still, tech companies did not escape entirely unscathed. Despite its high rank, Fronk says Apple’s positive reputation is anchored in the survey by positive perceptions of its financial performance — the aspect of its business over which it has the least control. As the company’s plunging stock over the last several months shows, the investing public has no problem tarnishing the reputations of tech companies that don’t live up to expectations


“You don’t want to have the conversations about you moving from innovation and the joy you bring, to always being about the share price,” Fronk says.


Of the most talked-about tech companies, Facebook by far received the least love. While Amazon, Apple and Google all ranked in the top five with total scores above eighty out of 100, and Microsoft ranked 15th with a “good” score above 75, Facebook came in 42nd – sandwiched between Best Buy and T-Mobile – with a score of just over 65, or what Fronk described as the borderline between “average” and “poor.”


“Facebook suffers badly from lack of trust,” Fronk said.


Amazon arguably collects as much personal data about its customers as Facebook does about its users, or at least if not as much, then possibly more intimate: purchase history, product search history, home address, credit card numbers. The Harris survey didn’t ask specifically about individual companies’ use of personal data. Yet it’s hard not to infer that privacy concerns were on the minds of survey participants when answering questions about trust.


Forty-six percent of all respondents said they “definitely would trust” Amazon “to do the right thing.” Only 8 percent said the same about Facebook. Add in “probably would trust” and Amazon’s total shoots to 91 percent, while Facebook’s reaches 49 percent.


Whatever Amazon is doing, or not doing, to earn itself so many points, Facebook apparently needs to take some notes, at least according to this poll’s results. By Harris’ tally, Amazon is the first company in the survey’s history to score negligible negative results across every category. If the results are to be believed, no one really hates Amazon. Says Fronk: “There’s not a detractor base whatsoever.”

Watch Live: Historic Landsat Earth-Observing Satellite Launch











At 10:01 a.m. PST, a team of scientists and engineers will hold their breath as the newest Landsat satellite is launched into space aboard an Atlas V rocket. Landsat 8 carries one of the most sophisticated Earth-observing systems, but it also carries the weight of a record-breaking 40-year-long continuous mission.


The Landsat mission is the longest continuous effort to image the Earth, and it has endured many setbacks, failures and near cancellations to get to this moment. Landsat 8 will both rescue the continuity and advance the scientific capability of the mission, if it reaches orbit. If it doesn’t, it won’t be the first Landsat satellite to fail.

In 1993, Landsat 6 didn’t make it to orbit, leaving the nine-year-old Landsat 5 with the task of staying alive even further beyond its three-year planned mission. Fortunately, the satellite soldiered on until January of this year. Since then, Landsat 7, which was hobbled by a technical failure that affects its ability to image the entire 185-kilometer-wide swath of Earth it covers on each orbital pass, has been carrying the torch alone.


“The failure of Landsat 6 was a big setback,” said Landsat’s lead mission scientist James Irons. “We were very fortunate that Landsat 5 persisted as long as it did or we would have suffered a gap.”


But Landsat 6 was developed and launched outside of NASA’s control by a provate company, and Irons is confident that all should go well for Landsat 8.


“I’m reassured that the NASA process has the utmost rigor in insuring success,” he said. “Still, you realize all rocket launches have some inherent risk, so, it’s just hold your breath and hope everything goes well.”
