Plant-based omega-3 polyunsaturated fatty acids (PUFA) may have a protective effect on bone health, according to a team of Penn State researchers who carried out the first controlled diet study of these fatty acids contained in such foods as flaxseed and walnuts.
The genomes of the largest collection of families with multiple cases of autism ever assembled have been scanned and the preliminary results published in Nature Genetics (February 18, 2007). They provide new insights into the genetic basis of autism.
By first probing the way primitive yeast make cholesterol, a team of scientists has discovered a long-sought protein whose human counterpart controls cholesterol production and potentially drug metabolism.
A Johns Hopkins-led study has found evidence that a genetic tendency toward suicide has been linked to a particular area of the genome on chromosome 2 that has been implicated in two additional recent studies of attempted suicide.
A 46-year-old former fitness instructor, suffering from biventricular end-stage heart failure and in irreversible cardiogenic shock, has become the first to receive a new temporary Total Artificial Heart in the Northeast US by cardiac surgeons at the University of Pennsylvania Health System.
A new study from Saint Louis University researchers shows that young transplant patients who lose their federally provided insurance coverage are more likely to stop taking necessary anti-rejection drugs, which can increase the risk of losing the transplanted organs.

New results in the field of RNA research establish that the RNA splicing factor SF2/ASF can act as a cancer-causing protein by changing the alternative splicing of other genes critical for growth-control of cells.
Tomorrow AAAS Fellow, Robert C. von Borstel will talk about how cancer cell mutation and selection are metaphorically similar to the evolution of a new species.Like the first pregnant finch that landed in the Galapagos, the first cancer cell in a body has to undergo many mutations through many generations to establish itself. But once there, like any newly stabilized species in different ecological niches, cancer is tough to get rid of.
Women who eat seafood while pregnant may be boosting their children’s IQ, says new research.
