- Losses of long-established genes contribute to human evolution
12-13-2007 · EurekAlert!
While it is well understood that the evolution of new genes leads to adaptations that help species survive, gene loss may also afford a selective advantage. A group of scientists at the University of California-Santa Cruz led by biomolecular engineering professor David Haussler has investigated this less-studied idea, carrying out the first systematic computational analysis to identify long-established genes that have been lost across millions of years of evolution leading to the human species.

- Wildebeest or malaria parasite -- same rules determine number of offspring
01-14-2008 · EurekAlert!
New research published today (Jan. 15) in Proceedings of the National Academy of Sciences by a Biotechnology and Biological Sciences Research Council Fellow shows that the same community ecology principles that determine how different animal species on the savannah affect each other's population sizes through competition for food and hunting by predators also affect parasite species interacting within the microcosm of a single host. The research has implications for treating many human and animal infections.

- Younger African American women at significantly higher risk for breast cancer
11-07-2006 · EurekAlert!
Despite recent overall declines in invasive breast cancer in the United States, African American women, particularly younger ones, have not seen a significant decline in their rates. These findings, which are being presented at the American Pubic Health Association (AHPA) Annual Meeting in Boston, November 4-8, suggest the need for research to understand why these differences persist and to determine whether avoidable or preventable factors account for these patterns.

- Canadian breast cancer guidelines do not meet their objective
03-12-2007 · EurekAlert!
The Canadian Practice Guidelines for the Care and Treatment of Breast Cancer, first published in 1998, were developed to reduce variation in the way that breast cancer was being treated. Steven Latosinsky and colleagues performed a population-based study to determine whether the guidelines have influenced practice.

- Scientists seek marijuana's isotopic fingerprint
06-21-2007 · EurekAlert!
Scientists at the Alaska Stable Isotope Facility can tell whether marijuana confiscated in a traffic stop in Fairbanks likely came from Mexico or the Matanuska Valley.They're also working on a way to determine whether it was grown indoors or out.A few more years and enough samples and they hope to have something even more precise: an elemental fingerprint that could tell police where and under what conditions a sample of marijuana was grown.
