A 9V Battery To Your Brain Can Improve Your Gaming 167

autospa writes with an intriguing story found at Nature about direct electrical stimulation's effect on the brain. By applying low levels of electrical current to different parts of the brain via electrodes placed on the scalp, University of New Mexico researchers claim to have documented some significant changes in brain activity, which vary depending on the part of the brain targeted. Gamers, take note: in one experiment in which volunteers were recorded while playing a video war game, "those receiving 2 milliamps to the scalp (about one-five-hundredth the amount drawn by a 100-watt light bulb) showed twice as much improvement in the game after a short amount of training as those receiving one-twentieth the amount of current." The idea of affecting the brain by electric stimulation isn't new; but the battery-powered, non-invasive variety naturally leads some people to consider rolling their own.

Robotic Mold 118

Canis Lupus writes to mention that researchers from the University of West England are designing the world's first biological robot, constructed from mold. The robot, "Plasmobot," will be created using vegetative slime mold called plasmodium (Physarum polycephalum) that is commonly found in forests, gardens, and most damp places in the UK. "This new plasmodium robot, called plasmobot, will sense objects, span them in the shortest and best way possible, and transport tiny objects along pre-programmed directions. The robots will have parallel inputs and outputs, a network of sensors and the number crunching power of super computers. The plasmobot will be controlled by spatial gradients of light, electro-magnetic fields and the characteristics of the substrate on which it is placed. It will be a fully controllable and programmable amorphous intelligent robot with an embedded massively parallel computer."

More Climate Scientists Now Support Geoengineering 458

ofcourseyouare writes "The Independent is a UK newspaper which has been pushing hard for cuts in CO2 emissions for years. It recently polled a group of 'the world's leading climate scientists,' revealing a 'growing support for geoengineering' in addition to cutting CO2 — not as a substitute. For example, Jim Lovelock, author of The Gaia Theory, comments: 'I disagree that geoengineering the climate is a dangerous distraction and I disagree that on no account should it ever be considered. I strongly agree that we now need a "plan B" where a geoengineering strategy is drawn up in parallel with other measures to curb CO2 emissions.' Professor Kerry Emanuel of MIT said, 'While a geoengineering solution is bound to be less than desirable, the probability of getting global agreement on emissions reductions before it is too late is very small.'"

Geoengineering To Cool the Earth Becoming Thinkable 419

johkir writes "As early as 1965, when Al Gore was a freshman in college, a panel of distinguished environmental scientists warned President Lyndon B. Johnson that CO2 emissions from fossil fuels might cause 'marked changes in climate' that 'could be deleterious.' Yet the scientists did not so much as mention the possibility of reducing emissions. Instead they considered one idea: 'spreading very small reflective particles' over about five million square miles of ocean, so as to bounce about 1 percent more sunlight back to space — 'a wacky geoengineering solution.' In the decades since, geoengineering ideas never died, but they did get pushed to the fringe — they were widely perceived by scientists and environmentalists alike as silly and even immoral attempts to avoid addressing the root of the problem of global warming. Three recent developments have brought them back into the mainstream." We've discussed some pretty strange ideas in the geoengineering line over the last few years.
