Prosthetics have come a long way since the days of wooden legs. Now a team of Stanford researchers says it's taken a big step towards developing an artificial skin that can actually "feel" pressure and could someday help amputees and burn victims.
Spray-on carbon nanotubes and deformable silicone storing an electrical charge form the stretchy, sensitive material that's being billed as a synthetic skin prototype by the team of Stanford researchers led by associate professor of chemical engineering Zhenan Bao that developed it. The flexible, skin-like sensor can be stretched in any direction without tearing, losing its shape, or wrinkling and it's sensitive enough to detect a wide range of pressure.
"This sensor can register pressure ranging from a firm pinch between your thumb and forefinger to twice the pressure exerted by an elephant standing on one foot," Darren Lipomi, a Stanford post-doctoral researcher who helped develop the artificial skin sensor, told PopSci.com.
According to the Japanese branch of Domino's Pizza, the company says it will have a branch affiliate on the moon at an undetermined time in the future.
"We started thinking about this project last year, although we have not yet determined when the restaurant might open," said Tomohide Matsunaga, a spokesman for Domino's in Japan.
"In the future, we anticipate there will be many people living on the moon, astronauts who are working there and, in the future, citizens of the moon."
Coming in at three feet four inches and 330 pounds, it’s Robonaut 2, NASA’s humanoid robot. Six months after it was first delivered to the International Space Station by Space Shuttle Discovery, the robot has been powered on for the first time.
Robonaut 2, or R2, tweeted the progress of its first test from the @AstroRobonaut feed, operated by NASA’s Joe Bibby, a multimedia specialist working out of Houston’s Johnson Space Center, where R2's ground support is located.
“My power cable is plugged in and my status LEDs on my power backpack are on,” Robonaut tweeted Monday morning.
How dark is dark within the solar system? We suppose black holes, by their very nature, are pretty dark. But high on the list of astronomical objects that don't reflect much light is a new contender: TrES-2b, a Jupiter-sized gas giant around 750 light-years from Earth that's now taking top billing as the darkest exoplanet that astronomers have ever discovered.
Brightness readings measured by NASA's Kepler spacecraft suggest that TrES-2b reflects less than 1 percent of the sunlight that hits it–and that's coming from a star a mere three million miles away from the planet itself (GSC 03549-02811). For comparison's sake, Earth is around 93 million miles from the Sun and, we should note, a whole lot cooler. The average temperature of TrES-2b hovers around 1,800 degrees Fahrenheit.
Although the super-heated planet's atmosphere is full of light-absorbing chemicals, there's no indication that their presence is the direct reason why the planet fails to reflect a great deal of light.
To celebrate its 50th birthday, Seattle's Space Needle is launching a contest to send someone into space.
"The Space Needle was built when our country was in a global space race," Ron Sevart, CEO of the Space Needle said in a statement. "With space travel moving into the private sector, a new race has begun that focuses on the best of what the Space Needle has become–a symbol of the aspirations of today's world of technology and science. What better way than sending a person from our midst into space to mark our first 50 years and look into the exciting future that lies ahead."
The contest, dubbed Space Race 2012, kicks off Monday. Potential astronauts can enter online via the Space Needle Web site through November 30.
NASA's James Webb telescope, the successor to the Hubble, is on the chopping block. With the U.S. Congress arguing over fiscal matters, one of the things that may get cut is NASA's budget, with the expensive James Webb telescope potentially getting the ax. If that happens, a generation of scientific discoveries about the nature of the universe may need to be put on hold.
Right now the future of the Webb telescope, scheduled to launch in 2018, is uncertain. Congress is looking to cut costs, and NASA's budget could be cut by as much as $1.6 billion (or about nine percent of its overall budget). Such a big cut would certainly be the death knell for the Webb telescope, which has so far cost $3 billion but whose final price is expected to hit the $6.8-billion mark.
"The cost overruns are driven by a couple things," says Rick Howard, the program director of the James Webb Space Telescope at NASA. "We've had ten or so technologies that needed to work in order to have this kind of telescope—mirrors actuators, the sunshade. We've made great progress, but it's taken longer and it's been harder than we thought. We've had to invent new adhesives for carbon fiber because what we thought was the right chemical equation didn't work at all. Another source was inadequate early funding of reserves."
If you've ever been cheated out of a window seat on a flight, you'll appreciate the concept plane Airbus just revealed at an airshow in Paris. In its vision of what air travel might be like in 2050, the aircraft manufacturer showed a plane with a transparent fuselage, giving all passengers a panoramic view of what's outside.
"The idea is to have a technology for the fuselage that's a bit like bones of birds that allows to have large spaces that can turn transparent, in order to look outside and 'live' the panorama in which you are flying," Charles Champion, Airbus' head of engineering, told London's Telegraph (see video below).
Airbus didn't hold back its designers' imaginations in conceiving features for the future plane. Besides a see-through hull that would make Wonder Woman consider a copyright infringement lawsuit, the concept aircraft would also discard the traditional class system of first, business, and economy. Instead, the Airbus from the future would have three zones: a Vitalizing Zone, with "organically grown" seats that can massage you; a recreational Interaction Zone, with pop-up "pods" for things like private dinners and a holographic gaming wall; and a Smart Tech Zone, where the seats adapt perfectly to individuals' size and shape.
If you're tired of waking up your significant other (or your significant other waking you up!) when the alarm clock goes off, you may want to take a peek at the Lark. They're calling it a silent "un-alarm" clock, and the promise is that it will wake you up without disturbing those around you. How does it work? You wear a sleep sensor on your wrist, and dock your iPhone, iPod touch, or iPad into the cradle. The device will now act as a bedside clock, while the sensor tracks all sorts of into about your sleep cycle. When it's time to wake up, the sensor on your write starts to vibrate, which is enough to wake you from your slumber.
The device will be available in Apple Stores starting on June 14th, and it'll cost $129. We've already got one in for review, so look for our thoughts on the Lark shortly.

UC Berkeley's Austin Whitney has been paralyzed since July 2007 as the result of a car accident that hospitalized the 22-year-old for a total of 41 days. And now, thanks to the research project of a team of Berkeley engineers, the history and political science double-major was able to stand up out of his wheelchair and physically walk across the stage to accept his diploma at the university's May 14 graduation ceremony.
"Ask anybody in a wheelchair; ask what it would mean to once again stand and shake someone's hand while facing them at eye level," said Whitney in an interview with Berkeley's NewsCenter. "It will be surreal, like a dream."
The exoskeleton project, run by Berkeley professor of mechanical engineering Homayoon Kazerooni, focuses on user comfort and affordability as its two chief design points. Instead of, "over-engineering" the machine, as Kazerooni and his team of researchers note, they designed the exoskeleton to seamlessly work with as few components as possible. That means fewer motors to impact movement, which necessitates a smaller amount of sensors to track movement, which leads to a simpler device that costs less than the current market price of a typical exoskeleton: $100,000 on up.
One of Richard Branson's Virgin Galactic spaceships on Wednesday completed a re-entry technique known as a "feather" configuration for the first time.
The SpaceShipTwo (SS2), known as the VSS Enterprise, has now completed seven solo flights since its December 2009 debut, but Wednesday's was the first that successfully tested out this re-entry procedure.
Virgin Galatic is Branson's commerical spaceflight program, which plans to take the average (albeit wealthy) tourist into space in the next two years.
The VSS Enterprise took off from a California runway this morning at 6:43am Pacific time attached to the WhiteKnight (WK2) carrier aircraft, the VMS Eve. The spaceship was controlled by Pete Siebold and Clint Nichols, test pilots from Scaled Composites, which designed and build the spacecrafts. Mark Stucky, Brian Maisler, and Brandon Inks manned the VMS Eve.
