For 60 years, the DNA double helix has provided an iconic image of how our genetic information is held and how it reproduces. Now scientists at the University of Cambridge in the UK – where Watson and Crick developed their ideas about the genetic code – have provided another pioneering insight into the workings of human genes.

LONDON – An unexpected finding about how tadpoles control the regeneration of a tail that has been lost will trigger new research into healing and regeneration of wounds and tissues in humans.

For a healthy pregnancy to have the best chance of surviving, the cells lining the uterus must undergo a short-lived burst of inflammatory activity about five days after ovulation, which must come to a halt 48 hours later, researchers have found. The discovery suggested new ways of treating women who suffer recurrent miscarriages.

A candidate drug that has previously been evaluated as a treatment for stroke turns out to be able to kill some types of pathogenic bacteria, an international team of researchers has found.

In a discovery that has important implications for the future of HIV therapy, an international team of researchers has identified the molecule by which the virus enters the immune cells known as dendritic cells.

LONDON – Scientists have tracked the cause of a rare genetic condition that causes muscular weakness to a mutation affecting neurotransmission.

LONDON – Two major networks of genes and their encoded proteins, involved in lipid metabolism and inflammation, play an important role in determining a person's risk of developing coronary artery disease (CAD), a new study has found.
