"A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects."
If diabetics are to keep their blood-sugar levels in a healthy range, they must rely on periodic visits to the doctor, but maybe, not for long thanks to an iPhone app and technology being developed now.
Sleep’s memory role discovered
The mechanism by which a good night’s sleep improves learning and memory has been discovered by scientists. The team in China and the US used advanced microscopy to witness new connections between brain cells - synapses - forming during sleep. Their study, published in the journal Science, showed even intense training could not make up for lost sleep. Experts said it was an elegant and significant study, which uncovered the mechanisms of memory. It is well known that sleep plays an important role in memory and learning. But what actually happens inside the brain has been a source of considerable debate. Researchers at New York University School of Medicine and Peking University Shenzhen Graduate School trained mice in a new skill - walking on top of a rotating rod. They then looked inside the living brain with a microscope to see what happened when the animals were either sleeping or sleep deprived. Their study showed that sleeping mice formed significantly more new connections between neurons - they were learning more. And by disrupting specific phases of sleep, the research group showed deep or slow-wave sleep was necessary for memory formation. During this stage, the brain was “replaying” the activity from earlier in the day. Prof Wen-Biao Gan, from New York University, told the BBC: “Finding out sleep promotes new connections between neurons is new, nobody knew this before. “We thought sleep helped, but it could have been other causes, and we show it really helps to make connections and that in sleep the brain is not quiet, it is replaying what happened during the day and it seems quite important for making the connections.” (via BBC News - Sleep’s memory role discovered)
Much like the computer on your desk or the iPhone in your hand, the entire Universe is programmable. Just as you can build apps for your smartphones and new services for the internet, so can you shape and re-shape almost anything in this world, from landscapes and buildings to medicines and surgeries to, well, ideas — as long as you know the code.
(Medical Xpress)—Northwestern Medicine scientists have newly identified a protein’s key role in cell and physiological aging and have developed – in collaboration with Tohoku University in Japan—an experimental drug that inhibits the…
In the next few months, highly secretive US military researchers say they will unveil new advances toward developing a brain implant that could one day restore a wounded soldier’s memory.
The Defense Advanced Research Projects Agency (DARPA) is forging ahead with a four-year plan to build a sophisticated memory stimulator, as part of President Barack Obama’s $100 million initiative to better understand the human brain.
The science has never been done before, and raises ethical questions about whether the human mind should be manipulated in the name of staving off war injuries or managing the aging brain.
