Learning from experience is all in the timing
Animals learn the hard way which sights, sounds, and smells are relevant to survival. New research in flies shows that the timing of these cues plays an important role in how mental associations arise, and elucidates brain pathways involved in this process.
New research shows that mosquitoes sense repellent through their legs
Scientists made the surprising discovery that the insects’ displeasure for touching DEET, the active ingredient in many repellents, helps prevent bites.
Cellular rivalry promotes healthy skin development
Scientists have discovered a curious phenomenon taking place in mouse skin: cells compete with one another for the chance to develop into mature tissue. The findings indicate that this antagonism is key to creating healthy skin.
Researchers find genetic link to tuberculosis
Rockefeller scientists have identified a genetic condition that makes people prone to developing tuberculosis. In a British population, they found that the condition underlies one percent of cases of the disease—a finding that may ultimately lead to new treatment options.
Research on repetitive worm behavior may have implications for understanding human disease
Studying microscopic worms, Rockefeller scientists have identified a brain circuit that drives repetitive behavior—providing potential clues for understanding some human psychiatric conditions.
New microscopy technique peers deep into the brain
Using new imaging technology, researchers can now record the activity of large populations of brain cells with unprecedented speed, and at new depths.
Scientists find brain mechanism that naturally combats overeating
Studying a brain region involved in memory, researchers discovered a set of neurons that help mice control their appetite.
Scientists identify genetic factors that may cause some people to become obese
New research on leptin, a hormone that regulates appetite, reveals a previously unknown mechanism that may be responsible for at least 10 percent of obesity cases. The findings could help identify individuals with treatable forms of the condition.
Inside the brains of hungry worms, researchers find clues about how they hunt
When looking for food, the roundworm C. elegans searches the same area for up to 20 minutes before trying its luck at more distant locales. New research on the worm’s brain explains how this behavior arises at the level of molecules and cells.
New findings could make mosquitoes more satisfied—and safer to be around
Scientists have learned new tricks that could be useful in preventing mosquito-borne illnesses such as Zika and yellow fever. A new study shows that some appetite-reducing drugs can curtail the insects’ impulse to feed on warm-blooded hosts.
