POPSOne hundred tesla without self-destructing Why would anyone need a magnet that strong? Greg Boebinger, director of the Magnet Lab, says that this magnetic field strength is the only way to test the properties of newly discovered high-temperature superconductors like iron oxyarsenide, which may improve the performance of MRI machines and high-voltage power lines while lowering their cost. A 100‑T magnet would also let you conduct certain zero-gravity experiments without traveling into space and let you develop magnetic propulsion systems that could eventually replace those that burn rocket fuel.

POPSNanowires prefer Deep Purple The band, not ultra violet, but apparently they weren't offered a very wide selection, and the wires grown by exposure to Deep purple are described as kinky. The intention is for wires to grow straight,which can be done more easily with the standard plasma. But they also said, if they ever find a use for kinky nanowires, they know what to do. There was no mention of the way the wires grew with the other music, but I imagine the growth can be as varied as the type of music. They mention that it didn't like the German music. I wondered if nanowires like polkas

POPSWant to Enhance Your Brain Power? Give Your Neurons an Electrical Jolt Very little is known about how TDCS works. Scientists theorize that the mild current primes the neurons for action but does not trigger the voltage spikes that neurons use to communicate. "Presumably, it is polarizing neurons and making them more or less likely to respond to inputs," Cognitive enhancement with drugs such as Ritalin, prescribed for attention deficit disorder, is already widespread, of course. A survey published online at Nature in April found that one in five respondents, most of whom were academics and scientists, reported using such drugs for nonmedical use. Electrical stimulation may prove even easier to access. "Half the people in this room could build this type of device with parts from RadioShack," Wassermann told a crowd at a neurotechnology conference in Cleveland last week.

POPSHuman-frog hybrids reveal autism's secrets To see if abnormalities in neurotransmitter signalling also underlie autism, Miledi's team collected brain samples from six deceased autistic patients, aged eight to 39. They fused brain-cell membranes, which house neurotransmitter receptors, together with Xenopus egg membranes. As a control, they did the same thing with brain cells from patients with no history of mental disorder. Miledi's team then doused the frog eggs in neurotransmitter chemicals, and measured the voltage generated within each egg. The neurotransmitter chemicals tell brain cells to pump charged molecules in and out the membrane, creating a voltage across the membrane. Since Xenopus eggs do not respond to the neurotransmitters, the human proteins are completely responsible for any electric current generated. Four of six autistic brains responded to neurotransmitters chemicals less vigorously than the controls.

POPSWhat if Electricity Was FREE??? The life story and work of Nikola Tesla. He invented AC electricity, Neon Lights, Radio transmission, The Electric motor, Wireless electricity transfer, Remote control, Hydraulics, Lasers, Space weapons, Robotics, and many, many more things. As Tesla claimed to have invented a way to harness free energy from the voltage difference in the ionosphere that causes lightning, he was seen as a threat to the world energy economy and most of his inventions were classified for national security by the US government. A lot of his discoveries in physics have not been released to the public, despite being invented nearly 100 years ago. In 2006 the first company publicly announced it could successfully power items by remote power without wires, (news.bbc.co.uk/1/hi/technology/6129460. stm) something Tesla had invented nearly a century ago.

POPS'Smart dust' to explore planets The main article mentions "millimetre-sized devices to explore far-flung locations" - so what happens when someone (or something) breaths one of these devices in? Do we want to start a interstellar war because some alien kid choked on 'smart dust' ?
