A 12-year study shows variation among primate groups in how the animals clasp hands during grooming, but consistency within them, even as group membership shifts over time.

For researchers who work with study participants in person, lockdowns made it impossible to obtain fresh data, a survey finds.

Some of the blood specimens collected in the United States for the NIH’s All of Us research program starting on January 2, 2020, have antibodies against SARS-CoV-2.

Researchers say evidence of hybridization between leukocytes and cancer indicates that this is a primary means of metastasis. Others disagree.

The largest study to date of the animals’ genetics provides robust evidence that they are adapting to survive a highly lethal, contagious cancer scientists feared would cause their extinction.

The material turns bright pink when it comes in contact with an enzyme produced by the fungus Candida albicans.

Researchers find that surges in COVID-19 case numbers are associated with deletions in the SARS-CoV-2 genome in an antigenic site of the spike protein. Some of these mutations are present in vaccine breakthrough infections or reinfections.

The NIH shared new data detailing complaints it has received in recent years, the latest in a series of steps taken by funding agencies and professional organizations to address misconduct.

Turkish officials are scrambling to clean up a massive, gooey plankton bloom that’s sliming the country’s ports and could suffocate the area’s marine ecosystems.

Having two different endosymbionts may allow the ciliate Pseudoblepharisma tenue to live in both oxygen-rich and oxygen-poor zones of the muddy bogs of southern Germany.

A pool of neural stem cells that ordinarily lies dormant in the brains of adult mice spawns two types of never-before-documented glial cells when artificially reactivated, potentially pointing to a novel mechanism of brain plasticity.

In an unexpected twist in neuroscience dogma, the cells on the receiving end of neurotransmission appear to be able to release glutamate to regulate the transmitting cell’s activity.

Researchers identify live bacteria in fetal guts, skin, lungs, and placentas that activate memory T cells, indicating that early exposure to microbes could help educate the developing immune system.

Researchers find traces of SARS-CoV-2 in the stool and blood of kids with the post–COVID-19 inflammatory disorder, and signs of increased intestinal permeability.

Researchers report chemical and molecular signatures of microbial activity from millions of years ago in mineral samples from abandoned mines in Sweden and nearby countries.

New analyses find that divergent transcription, in which one promoter directs the expression of two adjacent genes oriented in opposite directions, is conserved across all domains of life.

New genomic analyses reveal that piscine orthoreovirus first came to the Pacific in 1989, around the same time that salmon farms in the area started importing Atlantic salmon eggs from Europe.

Removal of the 14-day limit for culturing human embryos is one of the main changes in the revised recommendations from the International Society for Stem Cell Research.

TMAO appears to both stabilize other plant proteins and influence the expression of stress-response genes, researchers report.
