Happy People Are Healthier, Psychologist Says Happiness and other positive emotions play an even more important role in health than previously thought, according to a study published in the journal Psychosomatic Medicine by Carnegie Mellon University psychology Professor Sheldon Cohen. New Clues To Breast Cancer Development In High-risk Women Physicians who treat women with the breast cancer susceptibility gene BRCA1 often remove their patients'ovaries to eliminate the source of estrogen they believe fuels cancer growth. Yet they also know that anti-estrogen therapies don't work to treat breast or ovarian cancer that might develop. That paradox has led scientists to question exactly how, or if, estrogen is involved in cancer development and whether removal of ovaries makes sense. Singing In The Brain: Songs Are Stored As Snippets In The Minds Of Bir University of Utah scientists taught baby sparrows to sing a complete song even though the birds were exposed only to overlapping segments of the tune rather than the full melody. The study provides clues about how musical memories are stored in the brain and how those memories help birds learn to sing. Undergraduate Develops Antenna To Help Robot Move Like A Cockroach Can a robot learn to navigate like a cockroach? To help researchers find out if a mechanical device can mimic the pesky insect's behavior, a Johns Hopkins engineering student has built a flexible, sensor-laden antenna. Ulcerative Colitis Treatment Reduces Need For Surgery By Almost Half, A new study has found that ulcerative colitis patients had a 41 percent reduction in colectomy after a year when treated with infliximab. Prehistoric Aesthetics Explains Snail Biogeography Puzzle An odd distribution pattern of a rare snail has had biologists scratching their heads since at least the 1880s.

Stem Cell Licensing Deal Positions Toronto As World Leader In Technolo A $20-million deal announced June 21 to license Canadian stem cell technology in the US underscores the Toronto area's global leadership in stem cell research. Stem Cell Research Targets Birth Defects And Cancer After conducting research at Scotland's Roslin Institute (birthplace of Dolly, the cloned sheep) and creating in-vitro models of obesity and Parkinson's disease for the pharmaceutical giant Pfizer, Gabriela Cezar has returned to the University of Wisconsin-Madison. TechniqueProvides New Look On Response Of Diseased Canine Heart Using newly available biological technology, researchers have developed the first molecular portrait of multiple gene activity in diseased heart tissue taken from dogs near death from a devastating disease. The discovery sheds new light on the heart's response to dilated cardiomyopathy (DCM), a disease of large-breed dogs.
