Researchers made the find using an algorithm that purportedly distinguishes between mutations that were selected for and those that came along for the ride by coincidence, a feat that has long eluded scientists.

Several mechanisms contribute to the increased transmissibility of this SARS-CoV-2 variant.

Dozens of intranasally delivered vaccines targeting SARS-CoV-2 are in development. Could they pave the way for widespread nasal vaccination in the future?

Researchers find that tissue-resident memory T cells in the corneas of mice engender a lasting immune response.

A study identifies a gene that appears to be partially responsible for the health effects of a limited diet.

Two recent papers provide insight into possible risk factors for developing the chronic condition, including autoantibodies and diabetes.

An independent lab fails to replicate results suggesting mammals exposed to pathogens could pass on immunological protections through epigenetic mechanisms.

Researchers continue to debate whether US President Abraham Lincoln was coming down with smallpox as he delivered his famous Gettysburg Address, and if he had been immunized.

Researchers find that the protective outer layer that lungfish make to survive extended dry periods—once thought to be a simple mucus shell—contains immune cells that trap bacteria and protect the animals from infection.

While the weather isn’t currently the dominant factor driving SARS-CoV-2 transmission, experts say that in the future COVID-19 may become a disease of winter.

It’s unclear whether differing odds of dying between men and women reflect inherent differences between male and female immune systems or differences rooted in gender norms.

Offspring of animals subjected to a real or simulated pathogen were more able to fend off disease, a study finds.

The temporary loss of olfaction stops the flies from eating any more of whatever it is that made them sick.

The protein, apolipoprotein L3, destroys invading microbes by acting as a detergent in the cytosol.

Scientists are on the hunt for a shot that will protect against not only SARS-CoV-2, but other members of its family that may emerge in the future.

Mix-and-match shots could simplify vaccine rollout and stimulate more-robust immune responses. Ongoing clinical trials will soon give answers.

Two preliminary reports from the UK provide real-world evidence in support of the Pfizer/BioNTech and Oxford-AstraZeneca vaccines.
