Displaying the sleuthing skills of Sherlock Holmes, Jerry Harris carefully tracks the footprints to a point where they disintegrate into a muddle of scratches. He vividly deduces what transpired here. “Came up out of Lake Dixie,” Harris says, pointing to prints leading up the slope. “Sat down on the side of the berm . . . sat down in such a way that it rested both its hands and feet.” Continue reading
Long-necked Sauropods, like Brontosaurus, were the largest animals on earth, but their brain, not their leg strength, is what kept them from getting any bigger.
“A tendency to melancholy, let it be observed, is a misfortune, not a fault.”- A. Lincoln Continue reading
One of the fundamental questions motivating neuroscientists is to understand the relationship between brain activity and lived experience: how the different parts of the brain work together to produce the key ingredients for behavior: memory, feeling, thinking and imagination. These motivating issues have been pretty much inaccessible for most of the history of neuroscience, because we could not observe very much of the brain in action in enough detail to identify individual circuits or on the time scale on which they work. That is starting to change.
Cochlear implants have restored hearing to thousands of deaf people, but what about when deafness is caused by a damaged cochlea or nonfunctional auditory nerve? A possible solution is to bypass the cochlea and stimulate the brain directly. Scientists are developing a new technology that uses laser light instead of electricity to stimulate brain cells to restore hearing.
We are on the brink of a new understanding of the neuroscience of violence. Like detectives slipping a fiber optic camera under a door, neuroscientists insert a fiber optic microcamera into the brain of an experimental animal and watch the neural circuits of rage respond during violent behavior.

No, not that President! Thousands of people are captivated by the live video stream of a pair of bald eagles, named Mr. President and The First Lady, nesting on top of a Tulip Poplar tree at the U.S. National Arboretum. The reality peek into the life of a pair of breeding eagles, together with new research just published in the journal Nature Communications, show how parents decide which of their hungry chick gets fed. Begging is important, but sometimes begging is ignored and the parents feed their favorite. Now we know why . . .
