Artificial skin grows hair and sweat glands
You've probably seen artificial skin before, but never has it been quite so... accurate. Japanese researchers have grown skin tissue that not only includes hair follicles, but all the glands that come with it -- including oil and sweat glands. The trick was to take cells from mouse gums, turn them into stem cell-like forms that generate skin, and implant those into mice with immune system deficiencies (which lets the new skin grow unimpeded). The resulting skin was a little creepy -- just look at the wart-like growth above -- but it was healthy, behaved normally and made connections with natural tissue.
Robear is a robot bear that can care for the elderly
It's 2024. An older Japanese gentleman wants to watch the International Space Station's closing ceremony, but he can't get out of bed. No problem! All he has to do is call Robear to help him get up. Yes, that's his caregiver's name, but you see, Robear isn't human: it's a bear-like robot. This machine is actually the third and latest iteration of the beary helpful caregiver robot being developed by Japanese research institute Riken. The first model announced in 2009 was called RIBA, followed by RIBA-II in 2011, though Riken also came out with a Pillsbury Doughboy-like model way back in 2006 called RI-MAN. Robear weighs 309 pounds, making it a lot lighter than its 507-pound predecessor. It also has new features that ensure it's gentler and more careful while carrying patients to/from their beds or wheelchairs than the older versions.
Researchers create 'programmable' stem cells through stress
Making stem cells in the lab is typically a complicated process, and there isn't much variety in the results without resorting to foreign DNA. However, researchers at both Brigham and Women's Hospital and Japan's RIKEN may have found a way to easily create most any stem cell a doctor would need. Their new technique subjects adult cells to extreme stress, such as oxygen deprivation. The victims that survive the process retreat into a state much like that of an embryonic stem cell; after that, scientists just have to grow the cells in the right environment to get the stem cells they want. It will be a while before the team tests this process with humans, but it could lead to stem cells tailor-made for specific patients -- you'd only have to provide a blood sample to get replacement tissues.
Fujitsu's 10.51 petaflop K supercomputer is fastest in the world
Fujitsu, sweaty palmed from the construction of the K supercomputer, swore the colossal machine would manage a speed of ten petaflops by the year 2012. The effort has paid off handsomely: the hangar-sized machine has a top speed of 10.51. If you wanted to duplicate that setup at home, you'd only need 864 racks, 88,128 processors and enough cash in your back pocket to front an annual electricity bill of $10 million a year. The company will be spilling all at November's SC11 conference in Seattle, where the K will cement its position as the fastest computer in the world. One last thing -- we have a hunch that this machine can just about play Crysis.
RIBA-II healthcare robot now stronger, smarter -- still a bear
RIKEN's original RIBA healthcare robot was already fairly adept at lifting patients while not completely terrifying them but, as is the case with such things, it's now been succeeded by a new and improved model. While its outward, bear-like appearance hasn't changed, the new bot boasts a series of upgrades that now lets it bend over and lift patients up directly off the floor, not just off a bed or wheelchair. It's also now able to lift patients that weight up to 176 pounds (41 pounds more than before), and it packs an array of new sensors that let it more accurately gauge a person's weight and carry them more comfortably -- not to mention some touchscreen controls on its back for when it needs a bit of direction.

Fujitsu K supercomputer will do 10 petaflops in 2012, eat Crays for breakfast
10's a nice round number, isn't it? Round, yes, but also wildly impressive when you put the word "petaflops" behind it as Fujitsu has done with its upcoming K supercomputer, which will be able to crunch through 10 quadrillion operations every second. Compare that to the current champ of processing farms, Cray's Jaguar, which can handle only (only!) 1.75 petaflops of workload and you'll know that we're talking about a seminal leap in performance. Japan's Riken Research Institute is the fortunate addressee on the crates of ultrafast SPARC64 VIIIfx processors that Fujitsu is now shipping out and the current plan is to have everything up and running by 2012. In total, there'll be 80,000 CPUs, each possessing 8 cores running at 2.2GHz, which will be housed within 800 racks. So yes, there'll be a machine somewhere on the Japanese isle with 640,000 processing cores at its disposal. Feeling safe?
Video: Human-carrying robot bear gets cuteness upgrade
The original RI-MAN may have had the whole human-carrying thing down while still managing to be somewhat soft and cuddly, but it looks like the robot-makers behind it have decided to go one step further with their new model, which has been given a complete bear makeover (sans teeth and claws, thankfully). Now dubbed RIBA (or "Robot for Interactive Body Assistance"), the new bot is still intended to more or less act as a robot nurse, and can reportedly lift patients up to 135 lbs out of bed or a wheelchair, while also making use of a full range of tactile sensors and some special "soft skin" material to ensure the short journey is as comfortable as possible. Did we mention there's a video? Of course there is. Head on past the break to check it out.[Via Pink Tentacle]
Video: Riken and BSI-Toyota robot goes on a neural bender
You're looking at a very Futurama like man-robot from the latest mashup to hit the industry. This one has a brain. It's the result of research from Riken and BSI-Toyota whose goal is to develop robots and automotive systems driven by neurotechnology akin to that of our carbon-based brains. The research is expected to result in more sophisticated auto-safety technology, mind-controlled machinery, and a new breed of baby-shoe wearing robots for domestic friendship and health care. Fortunately, this wobbly tyke has a long way to go before he begins bending the steel girders required to produce the forced-suicide booths of our doom. First steps after the break.[Via Impress]
Japanese supercomputer breaks the petaflop barrier
Japan, which once topped the list of world's fastest supercomputers with NEC's Earth Simulator, has seen its position deteriorate in recent years in the face of faster machines like IBM's 280-teraflop BlueGene/L. Well now it looks like a new Japanese rig is poised to regain the top of the charts, and the most amazing thing about Riken's MDGrape-3 -- besides its claimed 1 petaflop performance -- is the fact that it cost only $9 million to build, giving it a per-gigaflop pricetag of just $15 (compared to the $140/gigaflop cost of IBM's top dog). Developed in conjunction with Hitachi, Intel, and NEC subsidiary SGI Japan, MDGrape-3 is being tasked with helping the pharmaceutical industry model new drugs, as it can calculate the chemical bonding properties of a proposed drug-protein combo in mere seconds. While BlueGene/L contains a whopping 130,000 processors distributed over 65,000 nodes, Riken's closet-sized machine needs only 4,808 chips to achieve four times its speed for certain applications. Oh, and despite the impressive-sounding performance, due to the specialized nature of its design, its unlikely that you'll see MDGrape-3 rocking a game of Doom anytime soon.[Via Slashdot]
