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.
To grow new hair, stem cells throughout the skin must work in sync. Researchers have discovered the molecular communication tool, part of the lymphatic system, that the cells use to synchronize their activities.
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.
In studying cell division, scientists happened upon a new way of understanding how a chemotherapy compound works. The findings could make it possible to predict which patients are most likely to benefit from the drug.
Scientists have found that many receptors with high potential for drug discovery take a different configuration inside the body than in the test tube. The findings could explain why some promising drugs fail in clinical trials, and potentially open doors to new drug-development approaches.
Researchers have shown that antibodies against Zika might be involved in causing birth defects in babies born to infected women. The findings might provide important caveats for the development of a vaccine.
Navigating fruit flies do not have the luxury of GPS, but they do have a kind of neural compass. In a new study, researchers found that the animals decide which way to turn by comparing this internal compass needle to a fixed goal.
To fight off invading viruses, bacteria have evolved a slew of creative defense tactics. New research shows that in some cases, microbes go to great lengths to keep an infection from spreading, even destroying bits of their own genetic material.
