POPSScientists Identify Two Routes to Nerve Cell Regeneration In the long run, the optimal strategy for treating spinal injuries may involve a combination of therapies that restore neurons’ ability to grow axons and ones that counteract inhibitory signals near the injury. “You want to do each, and you may need to do both,”

POPSArtificial memory storage this is amazing. if it works it can be used not only for the sick, why not having an external hard drive to store memories, and new information, or to download some existing one, making space to newer? sounds intriguing, and yes it woulkd change human identity. But hey, why not?

POPSAn End to Paralysis with Artificial Brain-to-Muscle Connectors Say the researchers: Until now, brain-computer interfaces were designed to decode the activity of neurons known to be associated with movement of specific body parts. Here, the researchers discovered that any motor cortex cell, regardless of whether it had been previously associated with wrist movement, was capable of stimulating muscle activity. This finding greatly expands the potential number of neurons that could control signals for brain-computer interfaces and also illustrates the flexibility of the motor cortex. Human implementations for the technology are at least a decade away, but this discovery could be a game-changer for dealing with paralysis. One possibility would be to connect the motor cortex with an area of the spine below an injury. Signals would be re-routed around the damaged spinal cord, and could allow the brain to regain control of the paralyzed body parts affected by the injury.

POPSFrom Paralysis to function, how far are we? closer now Wow, very impressive progress! "the study, which appears in the journal Nature, scientists at the University of Washington in Seattle implanted ultra thin electrodes into the brains of macaques which had been trained to play a game that involved rotating their wrists to the left and right. While the monkeys played, the electrodes picked up electrical signals in their brains that made them tense different muscles. The scientists then injected the monkeys with a chemical that temporarily paralysed their arms. This time, signals from nerves in their brains were fed into a computer, cleaned up and magnified, and sent down a wire to muscles in the monkeys' wrists. When the monkeys tried to play the game again, they were unable to at first, but soon learned to control their wrist movements using the brain implant. when he found something worked, he quickly repeated it and adopted the strategy" very nice!

POPSSimple Low-Tech Home Wins Prize For Sustainability
Woodruff's house uses just 25% of the energy of a conventional house of the same size. His winter power costs are a $30 electricity bill each month and a cord of wood. In the summer, power is needed only for the hot water heater and appliances. Yet the little 1,100-sq.-ft. house is as straightforward as you can get. No high-tech gizmos. No elaborate contortions. The house relies on simple architectural principles -- windows oriented for sunlight, cross breezes for ventilation, overhangs for shade -- basics that were much lauded in the 1940s and '50s, but less emphasized since. They included large doors that can be opened for cross-breezes. They designed the heating so energy is used and reused within rooms. The living/ dining/kitchen area is one big room heated by a wood stove on rainy days, and the sun on sunny days. "The public rooms face east, the logic being you want those to heat up with the sun first in the winter and in the summer, you want to avoid the hot western sun.
