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 . . .
Tennis star Maria Sharapova has admitted to using the performance-enhancing drug meldonium, which boosts brain and body power and endurance. Here’s how it works.
I took a sip of sugary Coke and was struck by a hideous intense blast of aluminum. I rushed to the sink and spit out the tainted drink. Poison! What’s wrong with this Coke! I took another tentative sip. I was slammed again by the overwhelming metallic taste. I spat out the poison by rapid reflex. This can of Coke must have been contaminated during manufacturing! Or, had the likes of the Tylenol Killer switched to soft drinks? Then I remembered. . . the taste of Thanksgiving and mountain climbing!
The California Fish and Game Commission has banned crab fishing until further notice after detecting high levels of a neurotoxin in Dungeness and rock crabs. The toxin, domoic acid, is produced by certain types of planktonic algae, and it becomes concentrated in tissue of crabs and other marine organisms during plankton blooms. People who consume sufficient quantities of the toxin develop amnesic shellfish poisoning, so named because it kills neurons in a part of the brain that is critical for memory. Here’s how it works.
