Scientists dig deeper into the genetics of schizophrenia by evaluating microRNAs (5/12/2008)

Researchers have illuminated a window into how abnormalities in microRNAs, a family of molecules that regulate expression of numerous genes, may contribute to the behavioral and neuronal deficits associated with schizophrenia and possibly other brain disorders. ...> Full Article

Novel 'Gene Toggles' In Rice, World's Top Food Crop (4/15/2008)

Researchers have found a new type of molecule--a kind of "micro-switch"--that can turn off genes in rice, which is the primary source of food for more than half the world's population. ...> Full Article

Less can be more, for plant breeders too (3/25/2008)

Imagine you are a rice breeder and one day within a large field you discover a plant that has just the characteristics you have been looking for. You happily take your special plant to the laboratory where you find out that the spontaneous, beneficial event was due to inactivation of a single gene. This is a great observation; however, there are many different strains grown in different parts of the world, well adapted to the particular region they grow in. How can you now transfer the inactivated gene to other strains of rice? Conventionally, you would have to go through years and years of breeding, until you have successfully transferred that single gene, without affecting all the other genes that are responsible for the target strains being so well adapted to their local environment. Would it not be great, if one could do this faster? ...> Full Article

Short RNA strand helps exposed skin cells protect body from bacteria, dehydration and even cancer (3/4/2008)

Every minute, 30,000 of our outermost skin cells die so that we can live. When they do, new cells migrate from the inner layer of the skin to the surface of it, where they form a tough protective barrier. In a series of elegant experiments in mice, researchers at Rockefeller University have now discovered a tiny RNA molecule that helps create this barrier. The results not only yield new insight into how skin first evolved, but also suggest how healthy cells can turn cancerous. ...> Full Article
