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.
Scientists have long seen parallels between healing wounds and growing tumors. In studying the molecular changes that occur within both, a research team has discovered a new cancer-fuelling mechanism that potentially could inform drug development.
In some people whose cognitive functions are weakened due to Alzheimer’s, the disease can be traced back to changes in the brain’s blood vasculature. Scientists have found that a protein involved in blood clotting and inflammation might offer a potential path to new drugs.
Two new technologies are helping scientists understand new aspects of organ and nervous system development in C. elegans. One allows them to image worms developing in a natural environment, while the other makes it possible to track single neurons as the worms grow.
Since the first case was documented in the United States in 1938, the causes of autism have remained elusive. Hundreds of genes, as well as environmental exposures, have been implicated in these brain disorders. Sex also seems to have something to do with it: About 80 percent of children diagnose...
New findings from Rockefeller University researchers could guide the development of potent combination therapies that deliver more effective and durable treatment of leukemia. In recent work published in Nature, they show it’s possible to deactivate cellular programs involved in tumor growth by d...
