Study shows indicator for cardiovascular events
A study appearing in this week’s (March 19) New England Journal of Medicine (NEJM) confirms that a combination of gene variants previously associated with cholesterol levels does reflect patients’ cholesterol levels and can signify increased risk of heart attack, stroke, or sudden cardiac death. Led by researchers from the Massachusetts General Hospital (MGH) cardiology division,…

Of flies and fish
During her schooldays in 1950s Germany, Christiane Nüsslein-Volhard rarely did her homework. In 1995, she won the Nobel Prize for physiology and medicine. Volhard is now director of the prestigious Max Planck Institute for Developmental Biology in Tübingen, where, decades before, she had been an undistinguished biochemistry undergraduate. She was at Harvard this week (March…

Newly identified gene variants associated with prostate cancer risk
Three studies presenting newly identified genetic variants that are associated with increased susceptibility to prostate cancer were published recently (Feb. 10) on the advance online site of Nature Genetics. The 10 gene variants double the number of known variants associated with risk of the disease and are the result of genomewide association studies.

Scientists identify gene responsible for statin-induced muscle pain
Statins, the popular class of drugs used to lower cholesterol, are among the most commonly prescribed medications in developed countries. But for some patients, accompanying side effects of muscle weakness and pain become chronic problems and, in rare cases, can escalate to debilitating and even life-threatening damage.

DNA reveals Neanderthal redheads
Ancient DNA retrieved from the bones of two Neanderthals suggests that at least some of them had red hair and pale skin, scientists report this week in the journal Science. The international team says that Neanderthals’ pigmentation may even have been as varied as that of modern humans, and that at least 1 percent of…

‘Speed limit’ found on rate of evolution
Harvard University scientists have identified a virtual “speed limit” on the rate of molecular evolution in organisms, and the magic number appears to be six mutations per genome per generation — a rate of change beyond which species run the strong risk of extinction as their genomes lose stability.

Gene variants significantly increase risk for breast cancer
Newly identified inherited variants of a single gene increase breast cancer risk for women of European ancestry approximately 20 percent if they carry one copy of the gene and by 60 percent if they carry two copies. These variants, in the FGFR2 (Fibroblast Growth Factor Receptor 2) gene, were found in more than half of…

Advances in genetics can help kids learn
Education was becoming a no-brainer, some people at Harvard’s Graduate School of Education (HGSE) complained. Kurt Fischer and his colleagues looked at the revolution in brain scanning, genetics, and other biological technologies and decided that most teachers and students weren’t getting much benefit from them.

World’s largest flower evolved from family of much tinier blooms
The plant with the world’s largest flower – typically a full meter across, with a bud the size of a basketball – evolved from a family of plants whose blossoms are nearly all tiny, botanists write this week in the journal Science. Their genetic analysis of rafflesia reveals that it is closely related to a…
