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.

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...

The findings explain why some people are so vulnerable to the infection, and suggest new avenues for treatment.

A growing number of studies find that microbes in the gut directly influence biological processes from bowel movements to behavior. New research reveals how they impact levels of glucose in the blood.

New research identifies a protein that blocks infection by SARS-CoV-2, the coronavirus that causes COVID-19, along with several other types. The findings could inform treatment strategies and help us better prepare for future outbreaks.

Molecular CRISPR-Cas systems, most commonly known for their usefulness as gene editing tools, are ancient defense mechanisms employed by bacteria against viruses. The discovery of a counteracting viral trick could inform scientists' efforts to develop future gene-editing technologies.

Scientists hope to deploy antibodies in the quest to end COVID-19. A recent study moves them closer to accomplishing a key step: finding out if the virus may acquire resistance to antibody-based drugs or vaccines, and how to potent...


Scientists have engineeredĚýfour viruses resembling SARS-CoV-2 to enable faster and safer research on vaccines and treatments.

New findings characterize human antibody response to SARS-Cov-2, with implications for convalescent plasma therapy, vaccine design, and antibody-based drugs.


Llamas make antibodies that are much smaller than their human counterparts, yet still potent. Scientists hope that future drugs based on these molecules could provide new weapons against SARS-CoV-2.
