Although epigenetic changes were long thought to largely act on the genome, rather than as part of it, research is now showing that these patterns can, directly or indirectly, change the genetic code.

Evidence is mounting that epigenetic marks on DNA can influence future generations in a variety of ways. But how such phenomena might affect large-scale evolutionary processes is hotly debated.

Most differences in gene expression among cells within a tumor are likely due to environment or noise, a study suggests. 

A team proposes that the addition of a small accessory subunit to the carbon-fixing enzyme was key to improving its catalytic properties and specificity to CO₂.

Off the western Australian coast, in Shark Bay, a field of seagrass big enough to cover Washington, DC, has flourished for more than four millennia, a new study finds.

Analyzing the whole genome sequences of more than 18,000 tumors, researchers catalog nearly 60 new patterns of mutations that could inform cancer treatment.

A first-of-its-kind gene therapy dramatically reduced misfolded protein levels in some clinical trial participants for up to six months and reduced levels in all participants for up to a year.

The genes are involved in pacing the development of inhibitory and excitatory neurons. An imbalance in these two types of signaling is thought to play a role in autism.

He famously identified the genetic mutation that causes the condition in 1991.

The SARS-CoV-2 variant was first detected in January, but its rising prevalence and potential resistance to vaccines has garnered it special attention from the World Health Organization.

Genetic, transcriptomic, and epigenetic data reveal molecular mechanisms tying these disorders to each other and to immune disfunction.

The FDA pauses the research program on a lentivirus-based treatment for a rare neurological condition after a patient developed a bone marrow disorder that could presage leukemia.

The genomes of the children of people exposed to fallout from the Chernobyl nuclear accident appear to carry no trace of the incident.

The P.1 variant, which has also been detected in five US states, could be responsible for cases of reinfection, according to a preprint.

Cells found in different branches of a tree have different patterns of DNA methylation, changes in which accumulate over time.

Researchers identify deletions in the N-terminal domain of the spike protein that allow the coronavirus to avoid antibody neutralization and that may contribute to the emergence of new variants.

A preprint casts doubt on vaccine effectiveness in light of certain mutations in the 501Y.V2 variant that emerged from South Africa.

Whole-genome sequencing reveals a wide range of UV-induced DNA changes in human skin cells, and lighter skin collects more mutations, sometimes to “sky high” levels.
