Russia launches 'largest telescope ever made'

To look at the Russian RadioAstron spacecraft, which launched from Kazakhstan this Monday, it doesn't seem particularly record-breaking. Its 10-meter (33-foot) antenna is certainly no match for those on earthbound radio telescopes, which can be up to 300 meters (984 feet) across. Once in orbit, however, its signal will join forces with those from ground-based telescopes to form one giant virtual telescope. Using a process known as interferometry, they will form the equivalent of a single radio telescope dish that at over 350,000 kilometers (217,480 miles) across is almost 30 times wider than the Earth. Although it's not actually one physical object, it is nonetheless being heralded as the largest telescope ever created.



Interferometry itself is nothing new, having been around since the 1960s. Very basically speaking, it involves combining the output of two or more geographically-separated telescopes to obtain one image with a resolution higher than either telescope could achieve on its own.
While radio telescopes have been sent into space for this purpose before, the plan is for RadioAstron's oval-shaped orbit to take it up to ten times farther than any of those other spacecraft have traveled, at 10,000 to 390,000 kilometers (6,214 to 242,335 miles) from Earth. Working with telescopes in locations such as West Virginia, Germany and Puerto Rico, it should be able to capture details at 10,000 times the resolution of the Hubble Space Telescope.
Plans for its use include the observation of a huge black hole at the center of a nearby galaxy, M87.
Although already launched, it will still be a few months before the spacecraft reaches the starting point of its orbit, and then goes through a check-out period with its ground control team at Russia's Lebedev Physical Institute Astro Space Center. Once it starts receiving and transmitting data ... well, there will be a lot of it. It's estimated that RadioAstron will be taking in up to 144 megabits per second, which will be continuously relayed to the ground.
So far, however, there is only one 22-meter (72-foot) dish set up to receive that data, near Moscow. This means that much of the data will simply be lost. It is hoped that throughout RadioAstron's five-year mission, more receiving stations can be set up.

Human Skin Now In Production in Germany

Skin Scaffold A matrix with a vascular system, or BioVaSc (biological vascularized scaffold), on which skin cells can be cultivated at the Fraunhofer skin factory.
The factory can produce 5,000 penny-sized discs of whitish translucent tissue every month. The designers say it can also come in shades of brown. Each disc will cost about $72, a bit more than expected when the project was in its planning stages two years ago. The German newspaper Der Spiegel took a tour of the facility with its director, Heike Walles; check out their coverage here.
Robots and computers control the skin-making process, which takes place in a sterile, climate-controlled setting. The skin broth is closely monitored for any signs of infection and computers guide the lasers and blades that cut swatches of skin. The goal is to pave the way for factory-produced human tissue, complete with blood vessels, that could be used to treat injuries or various medical conditions.
As Der Spiegel puts it, Walles believes factories like this one will be the only way to efficiently produce new tissue like bladders, tracheas, cartilage and even human organs. She and others have successfully produced engineered tissue for human transplantation, but the process is hugely expensive and labor-intensive. An automated manufacturing facility could make it cheaper and simpler, she says.
For now, the tissue is being used in animal testing and could even be used for products like cosmetics, but it is still a long way from being transplanted. European Union regulations require several stages of animal testing before it could be used in a clinical setting, Der Spiegel reports.

SmartBird flying robotic seagull created by Festo.

Festo has added to its robotic menagerie with the creation of a robotic seagull that weighs just 450 g (15.87 oz) and boasts a wingspan of 1.96 m (6.4 ft). Dubbed the SmartBird, the ultralight flying robot was inspired by the herring gull and can take off, fly and land autonomously, without the help of any additional drive systems.



In creating the SmartBird, Festo says it has succeeded in deciphering the flight of birds. The robot's wings not only beat up and down, with a lever mechanism increasing the degree of deflection to increase from the torso to the wing tip, but also twist at specific angles along their length in the same way that a real bird's do so that the leading edge is directed upwards during the upward stroke.
Directional control is achieved through the opposing movement of the robot's head and torso sections, which is synchronized by means of two electric motors and cables. This enables it to bend aerodynamically, with simultaneous weight displacement, and is responsible for the SmartBird's agility and maneuverability.
As with a real bird, the SmartBird's tail isn't just for show either. It produces lift and functions as both a pitch elevator and yaw rudder. In addition to stabilizing the robot in a similar way to an aircraft's conventional vertical stabilizer, the tail also tilts to initiate left and right turns and rotates about the longitudinal axis to produce yaw.
Packed inside the SmartBird's torso are the battery, engine and transmission, the crank transmission and control and regulation electronics. Wing position and torsion can be monitored via two-way ZigBee protocol radio communication and can be adjusted and optimized in real time during flight.
Festo says developing the SmartBird has provided insights that will help it in a variety of areas. The robot's minimal use of materials and lightweight construction will help increase efficiencies in resource and energy consumption, while the functional integration of its coupled drive units have provided ideas the company says it can transfer to the development of hybrid drive technology. Additionally, analysis of its flow characteristics during development has provided insights into ways to optimize future designs. Another plus is that it won't try and steal your chips at the beach.

DIY Human-Powered Exoskeleton Makes You Bigger, Stronger, Funnier

Skeletonics Exoskeleton
Skeletonics, a six-month-old Japanese student project, has resulted in an exoskeleton made of plastic and metal that's surprisingly dexterous and powered solely by the human embedded inside. As a bonus, the promo video looks something like a live-action Sonic the Hedgehog cutscene.


As the Skeletonics suit is unpowered, it doesn't grant any kind of crazy strength or Iron-Man-esque powers--the Skeletonics is mostly designed to extend the reach of a human's arms and legs, while keeping freedom of movement and dexterity. It looks like it succeeds at that, packing both working fingers that are delicate enough to hand candy to a child and spring-loaded legs that are capable of (hilariously) chasing a criminal through an underpass.






There's some kind of weapon-ish thing embedded in the right arm--without any Japanese, I'm not totally sure what's going on in there, but it looks like a water cannon of some sort, which keeps with the Gundam-y feel of the rest of the exoskeleton. Anyway, the video starts to get really great around the 4:00 mark, when the manufacturing clips give way to guitar-rock-scored clips of the suit in action. Check it out:

Crazy Realistic Geminoid Robot Now Comes in Cool College Professor Variety

Sweet merciful fates: this is a robot. Called a Geminoid, these things came into fame with an early version in 2005 by Prof. Hiroshi Ishiguro of ATR. This new version seems completely revamped and updated and, more interesting, this is the first Geminoid from outside of Japan.





Japanese roboticist Hiroshi Ishiguro was responsible for the first Geminoids—super realistic androids capable of reproducing facial tics and other subtle mannerisms—but a team of researchers at Aalborg University in Denmark has fired back with their own fair-skinned take on the creepily realistic robot: the Geminoid DK.


DK already looks startlingly familiar, like he's the cool guy who teachers your English composition class at Uncanny Valley University, but he's still very much a work in progress. Currently, he's programmed to breathe and make his own involuntary muscular reactions, though both actions currently seem a bit too pronounced from these first videos. Nevertheless, he's considerably cheaper than Ishiguro's Geminoids, meaning that he'll be more widely available to robotics researchers. Oh and if you're late to class he punishes you with laser beams that shoot out of his eyes.
