Environmental pressure seems to spawn changes in the intrinsically disordered regions of enzymes in polar yeasts, allowing them to adapt to extreme cold.
The gut microbiomes of city-dwelling animals, including coyotes, lizards, and birds, show similarities to those found in humans who also live in urban environments.
The immunizations are designed to target the latest Omicron subvariants, and are only authorized for people who have already received their primary vaccinations.
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.
Milk fortifiers of human origin show no evident advantage in the development of the gut microbiota of premature infants over fortifiers derived from cows, while the intake of the mother’s own milk does, two studies suggest.
The 81-year-old director says that he will step back from his positions this December, but that he will continue working to advance science and public health.
Tortoise leaf beetles enjoy the protection the fungus provides from insect predators such as ants, then carry the microbe to a mutual plant host, which their fungal symbiont infects.
The monkeypox virus can easily spread between humans and animals. A veterinary virologist explains how the virus could go from people to wild animals in the US—and why that could be a problem.
When consumed for as little as two weeks, common alternatives to sugar affect intestinal bacterial communities, with some reducing the body’s ability to regulate blood glucose levels, 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.
