By engineering structures out of DNA, scientists could potentially prevent larger viruses, like coronaviruses and influenza viruses, from interacting with cells.

By analyzing the genomes of 23 remarkably long-lived fish species, a study found two metabolic pathways associated with longevity.

This year, cancer researchers uncovered a variety of ways that tumors can survive and spread, ranging from damaging their own DNA to exploiting the nearby microenvironment for nutrients.

The HIV protein Nef can cause long-term genetic changes that lead to hyperreactive immune cells, according to research in human cells and mice. 

Researchers find signatures pre- and post-vaccination that correlate with a more robust immune response. 

In the wake of Elon Musk’s takeover, many researchers are exploring their options with the open-source platform Mastodon.

King Charles III has a long history of promoting homeopathic or alternative medical treatments not supported by scientific evidence.

The Biogen-developed treatment, called lecanemab, appears to have a more clear-cut effect on slowing the disease than the company’s previous Alzheimer’s drug, Aduhelm.

A protein duo increases transcription of growth-related genes to enhance axon regeneration and boost plasticity, a study finds—but fails to improve mobility.

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.

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