Scientists have identified about two dozen genes that control embryonic stem cell fate. The genes may either prod or restrain stem cells from drifting into a kind of limbo, they suspect. The limbo lies between the embryonic stage and fully differentiated, or specialized, cells, such as bone, muscle or fat.By ...

Human cancer cells divide and conquer. Unless physicians can control that division with surgery, chemotherapy or radiation, the wildly dividing cells will eventually destroy a person's life.Researchers have known for some time that an enzyme called telomerase is crucial to cancer's progress. Now, for the first time, researchers at the ...

As they design new drugs to fight off influenza, scientists may not need to attack the virus directly. Instead, they may be able to stave off infection by targeting one of more than 100 proteins inside host cells on which the virus depends.These potential drug targets are the result of ...

Scientists funded by the Wellcome Trust have identified a key mechanism that enables malaria-infected red blood cells to stick to the walls of blood vessels and avoid being destroyed by the body's immune system. The research, published in the journal Cell, highlights an important potential new target for anti-malarial drugs.Malaria ...

Agroup of common genetics variants that affect the nicotine receptors inthe nervous system could significantly increase the risk of developingnicotine addiction. These results, which could have powerfulimplications for policy preventing tobacco use in young people, werepublished on July 11, 2008 in the open-access journal PLoSGenetics. Singlenucleotide polymorphisms (SNPs) are variations ...
