Axons connect neurons with each other to form the neural networks that underpin the vital functions of perception, motility, cognition, and memory. In many neurodegenerative disorders, from traumatic injury or toxic damage to diseases such as Alzheimer’s or Parkinson’s disease, axonal degenerati...

A regime of anti-HIV drugs —Ìýcomponents of regimens to treat established HIV infection —Ìýhas the potential to protect against infection in the first place. But real life can interfere; the effectiveness of this prophylactic approach declines if the medications aren’t taken as prescribed. ...

A face is more than a static collection of features. A shift in gaze, a tightening of the lips, a tilt of the head, these movements convey important clues to someone’s state of mind. Scientists know that two particularly social and visual creatures, humans and rhesus macaque monkeys, have a netwo...

Forgetfulness, it turns out, is all in the head. Scientists have shown that fading memory and clouding judgment, the type that comes with advancing age, show up as lost and altered connections between neurons in the brain. But new experiments suggest an existing drug, known as riluzole and alread...

It’s the most basic of ways to find out what something does, whether it’s an unmarked circuit breaker or an unidentified gene — flip its switch and see what happens. New remote-control technology may offer biologists a powerful way to do this with cells and genes. A team at Rockefeller Univers...

Stem cells in early embryos have unlimited potential; they can become any type of cell, and researchers hope to one day harness this rejuvenating power to heal disease and injury. To do so, they must, among other things, figure out how to reliably arrest stem cells in a Peter Pan-like state of in...

Whether stubbing a toe or stroking a cat, the sensation of touch starts out as a mechanical force that is then transformed into an electrical signal conveying pain or other sensations. Tiny channels in neurons act as translators by helping to formulate that signal to the brain. However, scientist...

The female mosquitoes that spread dengue and yellow fever didn’t always rely on human blood to nourish their eggs. Their ancestors fed on furrier animals in the forest. But then, thousands of years ago, some of these bloodsuckers made a smart switch: They began biting humans and hitchhiked all ov...

In a significant technical advance, a team of neuroscientists at ÐÓ°É has devised a fast, inexpensive imaging method for probing the molecular intricacies of large biological samples in three dimensions, an achievement that could have far reaching implications in a wide arra...

Mice and humans share a lot more than immediately meets the eye, and their commonalities include their telomeres, protective ends on chromosomes. But in recent years, the role of one particular protein at telomeres has puzzled scientists. New work at Rockefeller University has solved the contradi...
