Researchers develop battery boosting Power Felt, encourages you to sit on your phone
For whatever reason, researchers have long been stuck on the idea of harnessing the wasted energy potential of the human body. We've seen our nation's brightest try to siphon power off of our spare body heat, our breath and even our blood -- we haven't been able to cast off our wall chargers just yet, but progress is being made. Today's no-socket wonder comes from Wake Forest University's Center of Nanotechnology and Molecular Materials, and it falls into the body-heat category. Power Felt, a new fabric-like thermoelectric device comprised of layers of carbon nanotubes and flexible plastic fibers, can create an electrical charge from temperature differences. The Power Felt's layered nanotubes allow it to generate more electricity than standalone carbon nanotube / polymer composite films and, according to researchers, could add only $1 to the cost of a charging cell phone cover. "Imagine it in an emergency kit, wrapped around a flashlight, powering a weather radio, charging a prepaid cell phone," said project head David Carroll, "Literally, just by sitting on your phone, Power Felt could provide relief during power outages or accidents." The thermoelectric technology still has a long way to go before it's ready for the market, however, leaving the US military's technology savvy tailors hanging off the edge of their seats.
Bomb-sniffing crystals may save us from nuclear Armageddon, tea leaves agree
Worried that a nuclear attack might wipe out all of American civilization? You needn't be, because the scientific community's crystal ball says crystal balls may save humanity. Last week, the Department of Energy awarded a $900,000 grant to Fisk University and Wake Forest, where researchers have been busy exploring the counter-terrorist capabilities of strontium iodide crystals. Once laced with europium, these crystals can do a remarkably good job of picking up on and analyzing radiation, as the team from Fisk and other national laboratories recently discovered. Cost remains the most imposing barrier to deploying the materials at airports or national borders, though soothsaying scientists claim it's only a matter of time before they develop a way to produce greater crystalline quantities at an affordable price. The only thing Miss Cleo sees is a glistening press release, in your very near, post-break future.
Scientists restore memory of drugged rats, hope to do the same with people
Is there anything we can't learn from drugged up rats? Researchers at Wake Forest University and the University of Southern California used a group of medicated rodents to demonstrate a method by which memory can be restored with the flick of a switch. The rats were outfitted with tiny, rat-sized electrodes and exposed to pharmacological substances, which caused them to forget the connection between pushing a lever and getting water. By turning the electronic switch on, the scientists restored the rats' memory of the task -- turning it off made them forget again. The next step in the process is testing the experiment out on primates and perhaps some day utilizing the research to benefit victims of strokes, Alzheimer's, or injury-induced memory loss.
