Hunger-controlling brain cells may offer path for new obesity drugs
Within the oldest part of the brain, scientists have found cells in charge of controlling appetite and eating. The discovery could revitalize efforts to develop drugs for obesity that make us less hungry.
Faster-acting antidepressants may finally be within reach
Neuroscientists have taken a major step toward answering longstanding questions about how Prozac and similar drugs act in the brain. Their findings could lead to better antidepressants that don't take weeks to kick in.
In brief: How a microRNA protects against liver cancer
New insights about gene regulation in liver cells could lead to better treatments for a common tumor type.
Bruce Cunningham, former Rockefeller professor, dies at 77
Cunningham, a cell biologist, had been professor and co-head of lab with Gerald M. Edelman for more than 20 years.
New animal models for hepatitis C could pave the way for a vaccine
In the rats that roam New York City’s streets and tunnels, scientists have found a virus that resembles hepatitis C. They have used it to create the first animal model of the human disease, a breakthrough that potentially could yield a much-needed vaccine.
Geneticist and Rockefeller emeritus Peter Model dies at 84
Model's research on bacterial viruses provided valuable details about the way genes are expressed and control one another. He died on June 9.
In brief: A glimpse into the origins of antibiotic resistance
Scientists have identified several genetic mechanisms by which antibiotic resistance may have arisen in a bacterium that causes deadly infections.
A hidden movement in the molecule that makes RNA
Researchers have uncovered new details about the molecular machine that separates DNA strands before copying a gene's sequence into RNA.
In brief: Mapping the errors that disrupt heartbeat
By determining the structure of a protein linked to a deadly form of arrhythmia, scientists have gained new insights about the condition.
