One sponge-like material, three different applications

A new sponge-like material that is black, brittle and freeze-dried (just like the ice cream astronauts eat) can pull off some pretty impressive feats. Designed by Northwestern University chemists, it can remove mercury from polluted water, easily separate hydrogen from other gases and, perhaps mos...

Environmental exposures may damage DNA in as few as three days

Scientists discover that three molecules may be developed into new Alzheimer's drugs

A team of scientists has discovered three molecules –?from a search of 58,000 compounds –?that appear to inhibit a key perpetrator of Alzheimer's disease. Each of the three molecules protects the protein called "tau," which becomes hopelessly tangled in the brains of patients with Alzheimer's. Th...

Researchers make surprise discovery that some neurons can transmit three signals at once

Generations of neuroscientists have been indoctrinated into believing that our senses, thoughts, feelings and movements are orchestrated by a communication network of brain cells, or neurons, each responsible for relaying one specific chemical message called a neurotransmitter. Either neurons relea...

Scientists discover that three overlapping signals in embryo help get the backbone right

A major step in the development of the vertebrate embryo - the establishment of a back that morphs into a brain, spinal cord and muscles - turns out to be so important that the body uses at least three signals to make sure it happens properly. The discovery, reported this month in the journal De...
