SpaceX's scorched Dragon cargo capsule is on a ship making its way back to Los Angeles after Thursday's?historic descent from orbit.

The California-based company reported that the 14.4-foot-high (4.4-meter-high) spacecraft and its more than 1,300 pounds (620 kilograms) of cargo were in good shape, despite its plunge from the International Space Station. On the way down, the Dragon weathered re-entry temperatures in excess of 3,000 degrees Fahrenheit (1,650 degrees Celsius). At a height of 40,000 feet, the Dragon started deploying its parachutes and drifted into the Pacific, about 560 miles west of Baja California. A recovery team got to the craft, towed it to the ship and used a crane to hoist it aboard, as planned.

SpaceX spokeswoman Kirstin Brost Grantham told me that a few items will be delivered to NASA officials with a 48-hour turnaround, as a demonstration of the procedure for returning time-sensitive cargo from orbit. But the Dragon itself and most of its payload will be taking a slower ride to the port of Los Angeles. Arrival is expected around June 6, depending on weather.

From California, the craft and cargo will be trucked to SpaceX's rocket test facility in MacGregor, Texas, for postflight processing. Then the cargo will be turned over to NASA.

The handover of the Dragon's contents will be the last item to check off on NASA's list of requirements. That should clear the way for a $1.6 billion series of 12 Dragon cargo flights, with the first launch probably scheduled sometime in September.

NASA and SpaceX released a slew of awesome pictures and video documenting the Dragon's return, via SpaceX's Zenfolio gallery as well as NASA's Flickr and YouTube accounts. Here's a selection:?

During the re-entry of SpaceX's Dragon capsule, NASA and the United States Navy flew a P-3 Orion Cast Glance aircraft to capture airborne views of the spacecraft's descent. The aircraft, based at the Navy's VX-30 squadron at the Naval Air Station Point Mugu, Calif., was able to record Dragon's re-entry, parachute chute deployment and the capsule in the water.

The Dragon capsule nears American Marine's recovery ship, which is equipped with a crane to take the spacecraft on board.

Eventually, SpaceX is aiming for extensive reusability of its spaceship components, including a first stage that can fly itself back to the launch pad and a "Dragon 2.0" spacecraft that can do propulsive soft landings.

"That's how spaceships land in sci-fi movies," SpaceX's billionaire founder, Elon Musk, told me during a post-splashdown news conference. "And that's what also enables landing in other parts of the solar system. ... It's the way spacecraft ought to land."

But NASA won't be using this particular Dragon again. The space agency is buying a fresh spaceship for each of the 12 cargo supply missions. Musk speculated that SpaceX might send the scarred spacecraft on "a little tour of the country and show it to people around the country, [to] get students excited about space." In the future, Dragons could be refurbished for return trips to space.

Meanwhile, SpaceX is working to make the Dragon suitable for carrying astronauts as well as cargo. The development of the SuperDraco thruster system is a key part of that plan, because it fits into the propulsive-landing strategy as well as the launch escape system that NASA will require for safe human spaceflight. Musk said the system could go into operation in three years if the development effort goes well, "maybe four or five if we encounter some challenges along the way."

Other spaceship companies are making strides as well, with advice and financial support from NASA. Here's a quick progress report:

Orbital Sciences Corp., like SpaceX, has been receiving hundreds of millions of dollars to support the development of an unmanned cargo resupply system. Orbital is developing a new rocket called the Antares as well as its Cygnus cargo capsule to do the job. Last month, Orbital, Aerojet and NASA oversaw a full-duration hot-fire test of the AJ26 engine that will be used on the Antares. The first test launch from the Mid-Atlantic Regional Spaceport in Virginia is planned sometime in the next few months, and if all goes according to plan, cargo flights to the space station could begin by early next year under the terms of a $1.9 billion contract.

Blue Origin, the company founded by Amazon.com billionaire Jeff Bezos, is working on a spacecraft that could carry astronauts to the space station, with United Launch Alliance's Atlas 5 rocket to be used as the launch vehicle. On Thursday, Blue Origin reported that it successfully completed a systems requirement review of its orbital Space Vehicle. Blue Origin's president and program manager, Rob Meyerson, said in a statement that the review "paves the way to finalize our Space Vehicle design." Representatives from NASA and the Federal Aviation Administration took part in the review.

The Boeing Co. is developing its CST-100 capsule for NASA's potential use as a taxi for space station astronauts, to be launched by the Atlas 5. The company carried out drop tests in April and May to check the workability of its parachute-plus-airbag landing system. The most recent test involved dropping a CST-100 test vehicle from a helicopter, 14,000 feet above Nevada's Delamar Dry Lake Bed. Boeing's John Mulholland said the test validated the landing system design. Further ground tests of CST-100 components lie ahead, and test flights could begin in 2015-2016, Boeing says.

Video traces a parachute drop test of Boeing's CST-100 space taxi in the Nevada desert.

Sierra Nevada Corp. is developing a mini-shuttle known as the Dream Chaser, to be launched atop an Atlas 5 as a taxi for space station astronauts. This week, Sierra Nevada put the Dream Chaser through its first full-scale, captive-carry flight test. For this test, the space plane was suspended by cables beneath a heavy-lift helicopter. The first free-gliding drop tests are planned for later this year, and Sierra Nevada says the Dream Chaser could be operational by 2016.?

SpaceX, Blue Origin, Boeing and Sierra Nevada, along with other aerospace players such as ATK, Lockheed Martin and Astrium, are expected to compete for further funding from NASA later this year. Which means it's not likely to be a slow summer in the aerospace business. Has the successful Dragon mission made SpaceX the far-and-away frontrunner, or is the commercial space race up in the air? When will U.S. astronauts be flying once again on U.S.-made spaceships?

ALBUQUERQUE, N.M. (AP) ? A wall of smoke advances across a vast swath of rugged country in southwestern New Mexico where the nation's wilderness movement was born nearly a century ago.

From the air, the smoke stretches as far as the eye can see. On the ground, firefighters talk about the steep canyons that keep them from directly attacking what has become the largest wildfire in New Mexico's recorded history and the largest currently burning in the country.

Sure, things might look bad. But to land managers and scientists, the record-setting blaze represents a true test of decades of work aimed at returning fire to its natural role on the landscape ? a test that comes as many Western states grapple with overgrown forests, worsening drought and a growing prospect for more megafires.

The Whitewater-Baldy fire has destroyed a dozen cabins while marching across more than 354 square miles of the Gila National Forest. A pair of lightning-sparked fires grew together to form the massive blaze.

Unlike last year's megafires in New Mexico and Arizona, this blaze is burning in territory that has been frequently blackened under the watchful eye of the Gila's fire managers.

Starting in the early 1970s, the Gila has been leading the way when it comes to implementing such an active fire management strategy. Instead of immediately dousing flames in the wilderness, forest managers have let them burn as long as conditions are favorable.

The question that the Whitewater-Baldy fire is expected to answer is whether that strategy will pay off with more natural, less intense fires.

"There's a great opportunity here to study a fire like this," said Matthew Rollins, the wildland fire science coordinator with the U.S. Geological Survey's National Center in Virginia.

"The opportunity exists to look at how this fire has behaved differently in terms of vegetation mortality, effects on wildlife and fish habitat and water quality," Rollins said. "We can study how it burned in the wilderness relative to areas with other types of fire management strategies and other types of ignition patterns."

So far, the word from the fire lines is that the majority of the 227,000-acre blaze has burned with low to moderate intensity, not the kind of near-nuclear strength that was exhibited last year with the Las Conchas blaze in northern New Mexico. In that case, entire mountainsides were vaporized, leaving nothing behind but the white ashy skeletons of what used to be trees.

And as for those unburned pockets within the fire's boundaries, Rollins said he believes many of those spots have experienced low-intensity fire numerous times over the last century to make them more resilient.

Previously burned areas have also helped slow the flames on the fire's eastern flank.

"The fact that this is wilderness and the wilderness of the Gila has seen a lot of fires, we are comfortable with allowing it to burn. What we do is monitor it and help steer it around to keep some of the impacts lower than they would otherwise be on their own," said Danny Montoya, an operations section chief with the Southwest Incident Management Team.

Montoya said the rugged terrain has forced firefighters to attack the flames indirectly by starving the fire of fuels along its perimeter.

The smoke also has prevented direct attack from the air. Several helicopters and small planes are helping ground crews with backburn operations.

While a burn severity map has yet to be released, members of the incident management team are estimating that only 20 percent of the fire has burned at high intensity.

Last week, the fire made a 60,000-acre run in one day, scorching mixed conifer at high elevations as the flames were pushed by gusts of up to 60 mph.

That kind of fire can be devastating, experts said.

With fire behavior ranging from active to extreme, it will be some time before the scientists can get on the ground to see how the Gila has fared. Until then, they are working on gathering the decades of research done on the Gila, which is home to the world's first designated wilderness. It was the father of the wilderness movement, forester and conservationist Aldo Leopold, who pushed for the formation of the Gila Wilderness in 1924.

Tree ring data that dates back to the 1500s tells of the forest's fire history and the age of its trees. The perimeters of the Gila's fires along with information about their severity and vegetation mortality for the last century have also been compiled by the U.S. Forest Service.

There's also more ecological data from the federal Joint Fire Science program that can be used for comparisons.

"I think it's going to be a success story for the use of fire for managing forests," Rollins said. "It might not look like it on TV right now, but we haven't had any fatalities or dramatic housing loss like we see in Southern California or it burning so dramatically close to communities like last year's Las Conchas fire."

Experts agree that the Gila will see changes regardless of the severity of the fire. In the worst spots, aspens and other shrubs are expected to take over.

"When we're punching multi-thousand-acre holes in areas of ponderosa pine and drier mixed conifer types with no seed sources surviving, it's very difficult for those conifers to be re-established," said Craig Allen, a USGS ecologist based at Bandelier National Monument in northern New Mexico.

Fire managers are also expecting flooding. As the Las Conchas fire showed, steep denuded areas resulted in walls of water washing down canyons during the rainy season.

Residents in Glenwood are already worried about the prospect of flooding, and federal wildlife managers are concerned about what sediment and ash in the waterways could mean for the native Gila trout.

The U.S. Fish and Wildlife Service is also monitoring two packs of endangered Mexican gray wolves that are situated to the north and east of the fire. Last year, wolves in Arizona were able to escape the massive Wallow fire with their pups, but it's unclear how mobile the packs in New Mexico are since their pups are much younger.

The fire is about 15 percent contained, which much of that being on the fire's northern and northwestern flanks.

On Saturday, the more than 1,200 firefighters who are battling the fire continued to build lines to corral the flames before more threatening winds and dry conditions developed.

"We're going to continue fighting this fire aggressively without putting our firefighters in danger," fire information officer Lee Bentley said. "We're getting as much of a black line as we can around this fire."

Training cells to perform Boolean functions? It's logical

Thursday, May 31, 2012

Johns Hopkins scientists have engineered cells that behave like AND and OR Boolean logic gates, producing an output based on one or more unique inputs. This feat, published in the May issue of Nature Chemical Biology, could eventually help researchers create computers that use cells as tiny circuits.

Study leader Takanari Inoue, Ph.D., an assistant professor in the Department of Cell Biology and member of the Institute of Basic Biomedical Sciences' Center for Cell Dynamics at the Johns Hopkins University School of Medicine, explains that many researchers are striving to mimic devices in everyday use by engineering new qualities into biological materials, including biomolecules and cells. Several of those engaged in this relatively new field, known as synthetic biology, have tried to create biological computers.

At the heart of both the biological and the more everyday silicon-based variety of computers are Boolean logic gates, which produce responses that vary depending on what type and how many inputs they receive. For example, AND gates need two unique inputs to generate an output. In contrast, OR gates generate an output based on whether they receive one input, or another, or both.

Inoue says that previous research has shown some success in generating logic gates based on biomolecules in test tubes or petri dishes. However, he adds, developing logic gates using whole cells has proven significantly trickier. Most previous efforts have taken advantage of cells' transcriptional machinery ? the cellular processes that read genes to create proteins ? to generate an output signal. But transcription can be a slow process, taking from minutes to days to produce the desired response.

"People like to have speedy computation," Inoue says. "We were hoping to achieve computation in cells on the order of seconds, which is significantly faster than what people have achieved thus far."

To accomplish their goal, the researchers used a technique called chemically inducible dimerization, or CID. This tool takes advantage of natural biological mechanisms that bring together two proteins into a complex in the presence of a chemical.

Since AND and OR gates generate a response based on two different inputs, either together or separately, the researchers needed two different CID systems that didn't compete or overlap with each other. They relied on one system that's been studied for years, which brings two proteins, called FRB and FKBP, together in the presence of a drug called rapamycin. Rapamycin comes from bacteria, and FRB and FKBP come from animals.

In addition, they used a second CID system that brings together two other proteins, known as GID1 and GAI, in the presence of a plant hormone called gibberellin. Since this system is native to plants, the gibberellin-based system doesn't compete with the rapamycin-based one, Inoue explains.

The researchers engineered mammalian cells that produce all four of the requisite proteins, as well as a response when the right two proteins came together. When either FRB and FKBP or GID1 and GAI linked up, the cell's membrane developed ruffles easily visible under a microscope.

To create the OR gate, FRB and GAI were bound together at the cell membrane, while FKBP and GID1 were bound together floating freely in the cell. Adding either rapamycin, gibberellin, or both to cells brought the freely floating complex to the one at the cellular membrane, linking up the matching proteins and triggering the output signal.

To create the AND gate, the researchers placed just GAI at the cell membrane, with just FRB and complexes of FKBP and GID1 free-floating in the cell. This system required all four proteins to link up to produce membrane ruffling, which wouldn't occur without both input chemicals.

Tests showed that each of the engineered cellular logic gates produced the desired response reliably, in a matter of seconds. Additionally, as a second proof of principle, the researchers generated similar logic gates that used fluorescence as an output, which worked just as well and quickly.

Eventually, Inoue notes, researchers might use similar cellular logic gates to build larger, more complex circuits that could form the basis for computers that use cells as basic units. In the meantime, these individual cellular circuits could be engineered to produce specific outputs in the presence of chemicals, making them useful detectors or diagnostic agents. He adds that researchers might also use synthetic logic gate systems like this one to study how cells naturally produce outputs to keep bodily functions running smoothly.

VIA ARTiGO A1200 lets you roll your own miniscule, fanless PC

Most ultra-compact, fanless PCs are intended for the embedded market -- that is, not for the proletariat to tinker with directly. VIA's no stranger to serving that crowd, but it's making a point of addressing home users who want this class of PC for DIY projects, like home media servers, with the ARTiGO A1200. The new design is still using the dual-core, 1GHz Eden X2 of VIA's usual embedded PCs at its heart, but it comes wrapped in a smaller, more eye-catching package with HDMI video out and support for Windows 7. That's not to say that the A1200 represents a softening, inside or out. The PC can still survive temperatures between 32F and 113F with dust resistance in the bargain, and there's an array of ports you're still less likely to find on an everyday computer, such as a CFast slot (for storage) and dual gigabit Ethernet jacks. The $320 it costs to buy the new ARTiGO today won't get you an OS, RAM or a hard drive, but its ability to survive for years in a hot, dusty closet just might be worth the cost.

Get Radar Detectors ? Blog Archive ? Social Marketing

16:36 Social Media social marketing The Facebook IPO has failed even in the social network because nobody talks about it: the conversation is on Twitter. In spite of much talk of social networks and users, not much data about the real situation of women and their full extent. The Cocktail Analysis IV presented the wave of social networking Observatory. In this study we can observe several points, the general trend of users in the use of social networks since its inception to the present. 91% of Internet users have an active account and the average is 2.3 accounts. In the field of mobile, 55% of Internet users access this device from the same social networks. Plasma is also how social networks are an established reality, and that 92% of users leave a social network that is maintained in others. Due to the proliferation of platforms more and more offers and more options. So, the question is where are the Internet. Facebook has had a slight increase, reaching 85%. But more importantly, has become universal, with some users of 30.5 years on average. Tuenti is shown standing, with no growth, with younger users (25.5 years on average). Regarding Twitter, is booming, its use is increasing and has doubled its penetration from the previous study with 32%. As for the performance of brands in social networks, although the comments on the same purchase aroused the interest of consumers, are not priority areas to search for information on products. Social networks should not overshadow the other channels, as the websites and search engines are presented as the most important spaces for information when there is intent to purchase. The official website is still the option that most weight, being also important the search engines, forums and blogs in the case of mobile operators and technology, and less fashionable. A new bottle of red summer There are many brands for which the results they get from their online presence is clearly inadequate, more than 84% according to a report by BaseKit.
