COVID-19 causes a host of diverse complications, from lung inflammation to blood clots, heart failure, and brain fog. A team of scientists believes these attributes may have a single culprit—and that findings from research on Alzheimer’s disease might give them a leg up in finding it.

Unlike most humans, bats are naturally resistant to coronavirus infection. Researchers are now searching their genomes for clues that might explain why SARS-CoV-2 can cause devastating disease in our own species.

Researchers have found the first evidence that telomere shortening is not just a sign of aging, but a key component of the body's cancer prevention system.

A study of marine microbes reveals that conservation of nutrients is a fundamental property of cells in all living organisms, from plants to humans.

The largest map of gene expression in over 4 million human cells charts the dynamic path to forming different organs.

New research suggests that our immune system may play an active role in shaping the digestive-tract flora, which is tightly linked to health and disease.

The novel compound, discovered in Jan L. Breslow’s lab and now licensed to Bridge Medicines, will be designed to treat immune-mediated diseases without harming the rest of the immune system.

Female mosquitoes are armed with syringe-like stylets that begin to pump furiously only in the presence of blood. Scientists are now studying the specific neurons that line the stylet, and asking what mosquitoes taste when they bite us.

Rice will receive the 2020 Nobel Prize in Physiology or Medicine for research that led to a cure for hepatitis C, a viral disease affecting 170 million people worldwide. His lab worked on the virus for three decades and became the first to produce a version of it that could be grown and studied i...

Researchers studying two forms of skin cancer identified a long-overlooked factor determining why some tumors are more likely to metastasize than others: the physical properties of the tissue in which the cancer originates. The findings might set the stage for new ways to monitor and treat the di...
