People under 50 without preexisting conditions typically develop mild symptoms of coronavirus infection—but there are exceptions. Researchers are working to identify rare genetic variations that may explain why some in this group have succumbed to the disease.
For reasons that have long been unclear, cells stop dividing when the pH rises inside tiny cellular compartments called lysosomes. Now scientists have found an explanation for this phenomenon, with potential implications for drug development.
Researchers have identified a set of biological factors in mice that seem to determine one's ability to bounce back from a traumatic event, and provide preliminary evidence that a naturally-occurring substance may help boost resiliency in the face of stressful situations.
A new study finds that neurons affected in Parkinson’s disease can shut down without fully dying, allowing them to also switch off neighboring cells. The findings might give scientists a better understanding of how the condition wreaks havoc in the brain, as well as ideas for new treatments.
Allis, whose pioneering research established that enzymes that modify histone proteins, which package DNA in the nucleus, regulate gene expression, has been elected to the National Academy of Medicine.
Scientists have found a group of brain cells that influence body mass in two ways, by controlling how much we eat as well as how much energy we burn. The findings could lead to new drugs to help people shed weight.
