Brain encodes complex plumes of odors with a simple code

In the real world, odors don’t happen one puff at a time. Animals move through, and subsequently distort, plumes of odor molecules that constantly drift, changing direction as the wind disperses them. Now, by exploring how animals smell odors under naturalistic conditions, Rockefeller University ...

Protein found linking stress and depression

Stress, the ever-present threat to health and happy living, is tough on the brain. If the strain goes on too long, it can lead to debilitating psychological problems. Part of the reason, according to scientists at The Rockefeller University, may have to do with a little-known family of proteins c...

Brain protein may be a target for fast-acting antidepressants

It takes weeks or months for the effect of most antidepressants to kick in, time that can feel like an eternity to those who need the drugs the most. But new research suggests that a protein called p11, previously shown to play a role in a person’s susceptibility to depression, activates a seroto...

Gene linked to anxious behavior in mice

To measure anxiety in a mouse and suggest it’s similar to anxiety in a person may seem like a stretch, but the metrics sound uncannily familiar. Paralyzed by fear, afraid to leave the house or socialize with others, scared of new places, preferring the dark to the light of day. Researchers at The...

Dendritic cells as a new player in arteries and heart valves

In 1973, Ralph M. Steinman launched a new scientific discipline when he published his discovery of the dendritic cell, an odd-shaped player in the immune system. Since then, dendritic cells have proved to be critical sentinels on the lookout for foreign invaders, involved in early immune response...

Molecular machine turns packaged messenger RNA into a linear transcript

For RNA, the gateway to a productive life outside the nucleus is the nuclear pore complex, an amalgamation of 30 kinds of proteins that regulates all traffic passing through the nuclear membrane. New research from Rockefeller University shows that one of these proteins magnetically couples with a...

Stem cells in hair follicles point to general model of organ regeneration

Most people consider hair as a purely cosmetic part of their lives. To others, it may help uncover one of nature’s best-kept secrets: the body’s ability to regenerate organs. Now, new research from Rockefeller University gets to the root of the problem, revealing that a structure at the base of ...

Ritalin may cause changes in the brain's reward areas

A common treatment for attention deficit/hyperactivity disorder, prescribed millions of times a year, may change the brain in the same ways that cocaine does, a new study in mice suggests. Research from Rockefeller University shows that methylphenidate, commonly known as Ritalin, causes physical ...

Rockefeller neurobiologist proposes 'The end of sex as we once knew it"

Women are not from Venus any more than men are from Mars. But even though both sexes are perfectly terrestrial beings, they are not lacking in other differences. And not only in their reproductive organs and behavior, either, but in such unsexy characteristics as the propensity for drug abuse, fi...

Discovery could lead to a new animal model for hepatitis C

During its career, the potentially fatal hepatitis C virus has banked its success on a rather unusual strategy: its limitations. Its inability to infect animals other than humans and chimpanzees has severely hampered scientists in developing a useful small animal model for the disease. But now, i...
