A fluorescent protein derived from a Dead Sea microbe could be a novel way to track electrical signals in the brain, researchers say. It’s noninvasive and nontoxic, so it could enable neuron tracking without harming the neurons.
An updated version of a neurochip can monitor brain cells' communications at the clearest resolution yet, according to scientists in Canada. It's cellular-scale mind-reading -- or mind-listening, to be more precise.
A team of researchers from Japan and Michigan have built a molecular computer whose operation mimics a human brain. The tiny circuit, comprised of organic molecules on a gold substrate, is capable of super-fast concurrent calculations that rival the firing of neurons.
Wish you had a photographic memory? Well, Encyclopedia Brown, drugs may amp your brain up to that point soon. A group of Spanish scientists claim to have singled out a protein that can extend the life of visual memory significantly. When the production of the protein was boosted in mice, the rodents' visual memory retention increased, from about an hour to almost 2 months.
Scientists have achieved a new milestone in brain imaging: we have seen a memory in the process of being formed. Using brain cells from a lowly sea slug, which actually makes a good model for our brains, images were captured of proteins forming between the neurons. These proteins distinguish the memory as a long-term one rather than short-term, as the proteins solidify the memory in the neurons. This process had been suspected but not visualized until now.
If you cheat on your spouse, you can't yet plead biochemistry in divorce court. But rodent-brain research sheds light on why some lovers stay, some stray.

George is a typical Midwestern American male in the prime of his life, with an attractive spouse named Martha. George is a devoted husband, Martha an attentive wife. The couple has four young children, a typical home in a lovely valley full of corn and bean fields, and their future looks bright. But George is occasionally unfaithful. So, occasionally, is Martha. No big deal: That's just the way life is in this part of America.
