How mice teach us about disease

Researchers have created a large new resource of more than 900 genes switched off one-at-a-time in mice to discover which genes are important for a wide range of biological functions such as fertility or hearing.

Researchers discover new mechanism for human gene expression

In a study that could change the way scientists view the process of protein production in humans, University of Chicago researchers have found a single gene that encodes two separate proteins from the same sequence of messenger ...

Scientists reveal drinking champagne could improve memory

(Medical Xpress)—New research shows that drinking one to three glasses of champagne a week may counteract the memory loss associated with ageing, and could help delay the onset of degenerative brain disorders, such as dementia.

Study reveals how melanoma evades chemotherapy

Nitric oxide (NO), a gas with many biological functions in healthy cells, can also help some cancer cells survive chemotherapy. A new study from MIT reveals one way in which this resistance may arise, and raises the possibility ...
