Differences in impulsivity between individuals are linked to both experience and gene expression, according to a study on the ancestor of domestic chickens, the red junglefowl.

Microorganisms have persisted below the seafloor for millions of years under extreme energy limitations and continue to evolve.

A new genome-wide association study pinpoints new target genes, cell types and mechanisms for treating chronic kidney disease.

Researchers have conducted a comparison of the genomes of multiple strains of the cacao tree to provide insights into the role of genomic structural variants in the regulation of gene expression and chromosome evolution.

When agricultural weeds evolve resistance to herbicides, they do it either by target-site resistance, a mutation that prevents the chemical from fitting in the protein, or non-target-site resistance, the plant deploys enzymes to detoxify the chemical. Researchers have identified gene regions responsible for non-target-site herbicide resistance in waterhemp.

A gene called PfAP2-HS allows the malaria parasite to defend itself from adverse conditions in the host, including febrile temperatures, according to a new study.

Researchers have completed the first sequencing of a Brazilian snake’s genome. The study suggests that the nine genes that encode toxins produced by the jararaca pit viper Bothrops jararaca probably originated in genes that had different functions in the ancestral species.

The antiviral drug molnupiravir has been shown to reduce the transmission of SARS-CoV-2. Now, researchers reveal the molecular mechanism behind its action – the drug incorporates RNA-like building blocks into the RNA genome of the virus.

Researchers have described a new method for counting mutations and have found that one in 15 men are likely to carry mutations that could adversely affect their offspring.

In one of the most comprehensive computational efforts to explore heritable genomic variations, researchers have pinpointed nine processes during which most human genetic mutations tend to arise.
