The outbreak of the Sudan strain of ebolavirus, which includes eight other suspected cases, is the first to hit Uganda in more than a decade.

Immune cells deliver packages of telomeres to T cells, helping them retain their virus-fighting function over time, research suggests.

Researchers report that vaccination against proteins found on profibrotic cells reduced liver and lung fibrosis in laboratory rodents.

The results from two large clinical trials don't support the idea that supplements of the vitamin bolster immune defenses against SARS-CoV-2.

A bacterium that produces an insulin-like peptide can give mice type 1 diabetes, and infection with the microbe seems to predict the onset of the disease in humans, a study finds.

Immune defense genes in bacteria and archaea can identify viral proteins, a study finds, revealing similarities between the immune systems of prokaryotic and eukaryotic organisms.

Evidence thus far shows that pregnant people infected with SARS-CoV-2 are at higher risk for severe disease and death, as well as complications in their pregnancies.

The newly authorized intradermal vaccination only requires one-fifth of the usual vaccine dose. This will help stretch out the limited vaccine supply, experts say, but only if healthcare personnel receive sufficient training.

The Scientist asks Brigham and Women’s Hospital infectious disease specialist Lindsey Baden about testing for prior infections.

Research traces the evolution of a gene variant that reduces the risk of Alzheimer’s disease, finding that it originally evolved in response to infectious bacteria.

IgA antibodies appear to bind to specific species of commensal gut bacteria in mice, according to a study.

The marine animals have evolved a unique molecular pathway enabling them to use toxins to fight off invaders without poisoning themselves in the process.

Researchers are going beyond fecal samples to understand how the patterns of commensal microbes in the gastrointestinal tract influence development and health.

The Scientist spoke with Brigham and Women’s Hospital and Harvard Medical School researchers Scott Weiss and Yang-Yu Liu, who propose that people bank stool samples when they’re young and healthy so that they can be transplanted to rejuvenate the gut microbiome later on.
