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.
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 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.
Allis has received the March of Dimes Prize in Developmental Biology. The award, given to investigators whose research offers hope for the prevention and treatment of birth defects and other infant diseases, honors Allis for his groundbreaking work on gene regulation.
The centromere region of chromosomes retains the same DNA from one generation to the next. Scientists have gained new insights into how it avoids being scrambled in normal cells, and how it becomes unstable in cancer.
Researchers have identified a molecule that guides the formation of eggs and sperm by preventing a host of factors related to cell death and inflammation from killing the precursors to these cells. Their findings reveal new knowledge about how a mutation in this molecule leads to male sterility.
Some viruses can insert their genetic material into the genome of their host, creating a genetic fossil record. Researchers have uncovered how our ancestors may have wiped out one such virus around 11 million years ago.
