High Levels Of Testosterone Increases Appetite For Risk In Women; High Levels Connected To Choice Of Riskier Careers

The battle of the sexes rages on, this time from the trading floor. While there has long been debate about the social and biological differences between men and women, new research by the Kellogg School of Management at Northwestern University, the University of Chicago Booth School of Business and the University of Chicago's Department of Comparative Human Development explores how the hormone testosterone plays an important role in gender differences in financial risk aversion and career choice. Prior research has shown that testosterone enhances competitiveness and dominance, reduces fear, and is associated with risky behaviors like gambling and alcohol use.

New Journal Hormones Cancer To Be Launched In 2010

Springer, one of the leading publishers in the fields of science, technology and medicine, has signed an agreement with The Endocrine Society to co-publish a new journal, Hormones & Cancer, starting in January 2010. Hormonal cancers include two of the most deadly cancer subtypes, cancers of the breast and prostate. In addition to these cancers, Hormones & Cancer will include research articles covering other less-commonly occurring cancer subtypes, such as thyroid, gynecologic and pituitary cancer. The journal will help to bridge the gap between those working in the two often disconnected fields of endocrinology and cancer research. Hormones & Cancer will be a true translational journal, including basic scientific, epidemiological and clinical research papers.

Breast Cancer Drug Tamoxifen Appears To Raise Risk Of Developing New Type Of Tumor, Study Finds

Breast cancer patients taking a long-term course of the estrogen-blocker tamoxifen, which has been used widely to prevent recurrences of hormone-sensitive breast cancer, might have four times the risk of developing "an uncommon but aggressive" new tumor that is not estrogen-sensitive, according to a new study published Tuesday in the journal Cancer Research, the New York Times reports. According to the Times, the study by Christopher Li -- an associate member of the Fred Hutchinson Cancer Research Center in Seattle -- and colleagues was an observational study and not a randomized, controlled clinical trial. For the study, the researchers analyzed medical histories of more than 1, 000 women who were diagnosed with estrogen-sensitive breast cancer between ages 40 and 79.

Surprising Findings Of New Study: Plastics In Oceans Decompose, Release Hazardous Chemicals

In the first study to look at what happens over the years to the billions of pounds of plastic waste floating in the world's oceans, scientists are reporting that plastics - reputed to be virtually indestructible - decompose with surprising speed and release potentially toxic substances into the water. Reporting here today at the 238th National Meeting of the American Chemical Society (ACS), the researchers termed the discovery "surprising." Scientists always believed that plastics in the oceans were unsightly, but a hazard mainly to marine animals that eat or become ensnared in plastic objects.
