Paralyzed man first to move his arm by thinking about it
Helping paralyzed people move on their own has been a lot tougher than 1970s TV shows led us to believe it would be. For what they believe is the first time, researchers used tech to bypass a quadriplegic patient's severed spinal cord, helping him move his own hand with his mind and feed himself without aid. The work could lead to "a new generation of neurotechnologies that we all hope will one day restore mobility and independence for people with paralysis," says research lead Leigh Hocherg.
Paralyzed man regains use of arms thanks to 'wireless spinal cord'
Remember that paralyzed guy from Southern California who managed to walk on his own accord thanks to a revolutionary technique that bridged the gap in his severed spinal column with a wireless Bluetooth link? A team of doctors at Ohio's Case Western Reserve University have reportedly accomplished the same feat with a patient's arms.
Here's how Microsoft HoloLens could teach the next wave of doctors
Microsoft is big on using HoloLens to advance science and education, but what will that actually look like? You might have a good idea after today. The company has posted a video showing how Case Western Reserve University would like to use the holographic computer to teach medicine. Students could walk around anatomical models to see how bones, muscles and organs work in the context of a human body without resorting to cadavers. They could also produce simulations that let future doctors fail in a relatively low-stress environment -- there's no live patient here, after all. Although it'll probably be a while before you have to don HoloLens to complete a PhD, this clip shows that it's no longer an outlandish concept.
Researcher calls platinum wrong for fuel cell development, looks elsewhere for efficiency
Hearing that fuel cells aren't the most efficient thing in the world shouldn't take you by surprise, but a determination by one Alfred Anderson just might. The chemistry professor from Case Western Reserve University is now making a case for using something other than platinum as the "catalyst most commonly used to convert chemical energy to electricity." According to him: "Using platinum is like putting a resistor in the system." To be fair, Anderson still isn't sure which material should replace it, but he's adamant that wizards in the field should be spending their time looking for substitutes instead of tweaking platinum further. Currently, he's working with other researchers in order to find something that'll one-up what we're using today, and if you're into oodles of technobabble, you can dig into the ins and outs of his claims in the source link below.
Cyborg cockroaches inch closer to reality, blame science
Few things on this planet are more indestructible than the lowly cockroach -- except, of course, a cyborg cockroach. That's what researchers at Case Western Reserve University are looking to create, and they're a lot closer than you may think. In fact, chemistry professor Daniel Scherson has found a way to harvest energy from the chemicals swimming within these insidious insects, meaning that they may soon be able to create robot cockroaches with a more reliable power source. To do this, Scherson and his team incorporated enzymes capable of converting a cockroach's food intake into electrons, which can then be funneled through a fuel cell to generate electricity. Unlike similar developments, Scherson's technique doesn't rely on an external source like light, movement or batteries. All you need is a cockroach and a steady food supply -- basically, a college dorm room. [Image courtesy of The Life Files]
Self-healing polymer serves up quick fixes under UV rays (video)
As many self-healing polymers as we've seen roll across our screens, we never really tire of them -- chalk it up to our unending quest for perfection, but we like our gadgets devoid of nicks and scratches. Lucky for us, a team of scientists that shares our need for clean has produced a material that fixes its imperfections in a mere 60 seconds when exposed to UV light. The typically rigid material basically melts down when exposed to rays of a specific wavelength, allowing it to fill in any nicks or dings. When the light is lifted, the polymer goes back to its original form, and voila -- the surface is like new. Its creators say the material could be used on everything from cars to dining room tables, but we've already come up with laundry list of devices that could do with a truly scratch resistant surface. Video of the stuff in action after the break.
Study finds that text message-addicted teens more likely to have a life
According to a recent study lead by Dr. Scott Frank, an associate professor of epidemiology and biostatistics at Case Western Reserve University School of Medicine, kids in Cleveland who text over 120 times a day are more likely to have had sex or to have used drugs or alcohol than kids who don't send as many messages. We're guessing it's because it takes in excess of 120 text messages for kids to line up their drugs, alcohol, or sex partners. To explain the findings, Frank puts it this way: "If parents are monitoring their kids' texting and social networking, they're probably monitoring other activities as well." The study, based on a survey of 4,200 students, is one of the first to look at the correlation between texting and risky behavior in teenagers.
Infrared laser shown to quicken heart rate, gives hope for ultra-small pacemakers
Here's an interesting one. Just years after a researcher in Japan realized that lasers could stimulate nerves, a professor of biomedical engineering at Vanderbilt University along with cohorts from Case Western Reserve have found that the same is true with the heart. By using an Infrared laser on an early embryonic heart, tests were able to show that the muscle was "in lockstep with the laser pulse rate." The crew also found no signs of laser damage after a few hours of experimenting, though obviously more extensive research would be required before any medical agency allowed such a device to be beamed underneath a human chest. The hope here is that this discovery could one day lead to ultra-small, implantable pacemakers, or better still, to "pace an adult heart during surgery." There's nary a mention of when this stuff will actually be ready for FDA oversight, but there's a downright creepy video of it all in the source link. Consider yourself warned.
Justice Department settlement puts on-campus Kindle use on hold
Amazon may have recently announced it was beefing up the Kindle's functionality for vision-impaired users, but it looks like that's too little too late for three universities using Kindles as an alternative to textbooks, who have now agreed to shelve the e-readers until such enhancements are in place as part of a settlement with the Justice Department. Those universities include Pace, Case Western, and Reed College, who were all sued by two organizations representing the blind, which alleged that while the Kindle has a text-to-speech function, the menus do not, thereby making them impossible for blind students to use -- another university testing the Kindle, Arizona State, has already reached a similar settlement. Assuming Amazon lives up to its promises, however, it looks like the Kindles could be put back to use as soon as this summer -- and the universities in question will still be able to finish any pilot programs currently taking place this semester, just not expand their use.
Kindle DX college plans revealed: only 300 students total
We knew the Kindle DX pilot programs at Arizona State, Case Western Reserve, Princeton, Pace, Reed, and Darden School of Business at the University of Virginia would be limited in number, but it sounds like students at those schools will have be extremely lucky or well-connected to get their hands on Amazon's latest -- according to Pace reps at today's launch event, each school will only receive around 50 Kindle DXs for the trial. That's just about 300 total Kindles, and it makes Amazon's crowing about revolutionizing education seem a little hasty. Not only that, but it's not like the program is particularly ready to go, either: the schools still haven't figured out which classes they'll try and switch over to the Kindle, instructors have yet to be brought on board, and it's still not clear whether Amazon or the schools themselves will pay for the Kindles, although students will definitely have to shell out for the books. That's a lot of dealmaking to get done -- looks like Amazon just gave itself some summer homework.
