Menopausal whales are influential and informative leaders Posted: 05 Mar 2015 09:53 AM PST Menopause is a downright bizarre trait among animals. It's also rare. Outside of the human species, only the female members of two whale species outlive their reproductive lives in such a major way. Female killer whales typically become mothers between the ages of 12 and 40, but they can live for more than 90 years. Males rarely make it past 50. Now, researchers have new evidence to explain why.

Molecule found in tree leaves helps female mice combat weight gain; males unaffected Posted: 05 Mar 2015 09:53 AM PST A small molecule that binds to a receptor found on muscle cells speeds up energy metabolism -- but only in female mice. Researchers have shown that female mice treated with a molecule found in tree leaves could indulge in high-fat foods without gaining weight or accumulating fat. Males did not enjoy similar benefits, highlighting the need to study both sexes while developing drugs.

Biomolecular force generation based on principle of a gas spring Posted: 05 Mar 2015 09:52 AM PST The mechanical basis of mitosis has only been understood in fragments so far. Now scientists have been able to add another piece to the puzzle of cell biological mechanisms.

Baby mantises harness mid-air 'spin' during jumps for precision landings Posted: 05 Mar 2015 09:52 AM PST High-speed videos reveal that, unlike other jumping insects, the juvenile praying mantis does not spin out of control when airborne.

Immune abnormalities in patients with psychosis have been recognized for over a century, but it has been only relatively recently that scientists have identified specific immune mechanisms that seem to directly produce symptoms of psychosis, including hallucinations and delusions.

Cardiovascular disease kills 51% of women in Europe and breast cancer kills 3% Posted: 05 Mar 2015 05:13 AM PST Cardiovascular disease (CVD) kills 51% of women in Europe and breast cancer kills 3%, bucking the misperception that CVD is a man's disease. CVD is the top killer in women and is largely preventable.

'Life-prolonging' research for cystic fibrosis patients underway Posted: 05 Mar 2015 05:13 AM PST Preventing lung infections in childhood could stop later life-threatening infections for people with cystic fibrosis (CF), according to recent research. Scientists are investigating how bacteria found in children with CF can disarm their natural defence mechanisms, making it easier for more virulent bacteria to infect their airways. By the time many CF patients reach adulthood, they have already contracted the chronic Pseudomonas aeruginosa bacterial strain, which can cause extensive and eventually fatal damage to the lungs. The infection is currently extremely difficult to treat effectively.
