Microbes in the gut may influence metabolism
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.
Scientists uncover antiviral protein that blocks coronavirus infection
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.
How mechanical forces nudge tumors toward malignancy
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...
Newly discovered anti-CRISPR protein gives viruses a leg up against bacteria
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.
Study uncovers the molecular events by which popular antidepressants work
Scientists have outlined a molecular program by which serotonin reuptake inhibitors reshape the brain to alleviate depression. Their findings provide clues for how to make better and faster-acting versions of these drugs.
Will SARS-CoV-2 escape future drugs by mutating? The answer may be a nuanced “no.”

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...

A never-before-seen image of the coronavirus copy machine
The high-resolution 3D image can speed COVID-19 drug discovery.
How toothless mock viruses could advance research on COVID-19
Scientists have engineered four viruses resembling SARS-CoV-2 to enable faster and safer research on vaccines and treatments.
Bacteria in the gut have a direct line to the brain
Scientists find that microbes inside the intestines can control the activities of neurons connecting the gut and brain.
Amid the rush for COVID-19 drugs, a case for the helicase
The enzyme is essential for the virus to replicate itself inside our cells. Scientists already have ideas for how to block it.
