Learning how to control HIV from African genomes

A study on almost four thousand people of African descent has identified a gene that acts as natural defense against HIV by limiting its replication in certain white blood cells. An international effort co-led by EPFL, Canada's ...

Team proposes a new view on euchromatin in the cell

Scientists studying cells have long held the view that euchromatin, the part of chromatin that is made up of genes and is genetically active, is open and can be transcribed. A research team, looking at new evidence from genomics ...

Study identifies new mechanisms driving genomic instability

A recent Northwestern Medicine study published in the Journal of Cell Biology has identified new mechanisms that cause genomic or chromosomal instability during cell division, findings that may improve the development of ...

Examining how cooperation benefits from peer-punishment

A multi-lab replication of a 2006 study supports the role of peer sanction in promoting human cooperation. Cooperation is imperative for society to successfully solve complex problems, including climate change. One approach ...

Researchers shed new light on the motor of DNA replication

DNA replication is the process whereby cells make an exact copy of their DNA before cell division. A key part of the intricate DNA replication machinery is a molecular motor called CMG, which has the vital task of separating ...
