Study Nearly Doubles Known Cancer-Linked Mutational Signatures
Analyzing the whole genome sequences of more than 18,000 tumors, researchers catalog nearly 60 new patterns of mutations that could inform cancer treatment.

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.
Epigenetic structures appear to reduce the rate of changes in genes essential for survival and reproduction, a study finds, challenging the notion that mutations are evenly distributed throughout the genome prior to selection.
Anecdotal reports and results from small studies on the diagnostics’ accuracy have prompted questions about the devices’ usage with the new variant, but researchers say more data are needed and emphasize the continued importance of SARS-CoV-2 testing.
The Scientist interviews evolutionary biologist Carles Vilà about how a large genomic inversion detected in common quail affects the birds’ physical characteristics and migratory behaviors.
Researchers find that surges in COVID-19 case numbers are associated with deletions in the SARS-CoV-2 genome in an antigenic site of the spike protein. Some of these mutations are present in vaccine breakthrough infections or reinfections.
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.
An additional mutation in the spike protein of the coronavirus may help it elude antibody recognition, and scientists are investigating if current vaccines will protect against it.
Officials had initially linked 97 cases to a single conference held by Biogen in February in Boston, but a new study tracking viral genomes suggests the number may be as high as 20,000.
Wing development in females is environmentally controlled, but in males, an insertion on the sex chromosome appears to dictate whether the insects grow wings, according to a study.
