'Patchwork' tumors prevalent across multiple cancer types

Researchers at the Francis Crick Institute, as part of an international collaboration of scientists through the Pan-Cancer Analysis of Whole Genomes Consortium, have analyzed the whole genomes of tumor samples from over 2,600 ...

Viral sequencing can reveal how SARS-CoV-2 spreads and evolves

The emergence of SARS-CoV-2 virus variants that are adding twists in the battle against COVID-19 highlight the need for better genomic monitoring of the virus, says Katia Koelle, associate professor of biology at Emory University.

Could SARS-CoV-2 evolve resistance to COVID-19 vaccines?

Similar to bacteria evolving resistance to antibiotics, viruses can evolve resistance to vaccines, and the evolution of SARS-CoV-2 could undermine the effectiveness of vaccines that are currently under development, according ...

Happiness and the evolution of brain size

During human evolution, the size of the brain increased, especially in a particular part called the neocortex. The neocortex enables us to speak, dream and think. In search of the causes underlying neocortex expansion, researchers ...

Human brain size gene triggers bigger brain in monkeys

The expansion of the human brain during evolution, specifically of the neocortex, is linked to cognitive abilities such as reasoning and language. A certain gene called ARHGAP11B that is only found in humans triggers brain ...

TrackSig: Unlocking the history of cancer through tumor evolution

A tumor is often made up of different cells, some of which have changed—or evolved—over time and gained the ability to grow faster, survive longer and potentially avoid treatment. These cells, which have an "evolutionary ...

New clues into the genetic origins of schizophrenia

The first genetic analysis of schizophrenia in an ancestral African population, the South African Xhosa, appears in the Jan. 31 issue of the journal Science. An international group of scientists conducted the research, including ...
