Biology
The Washington University Department of Biology is par of the Division of Biology and Biomedical Sciences. The Division riginated in 1973 as one of the first interdisciplinary graduate programs in the nation. This interdisciplinary approach is key to solving emerging biological and biomedical problems in the "post-genomic" era. The Department is internationally recognized as outstanding, particularly in the areas of cell biology and molecular biology.

Workaholic
Single-celled bacterium works 24-7, converting light to energy by day, moonlighting at night
April 28,
2008 -- Researchers at Washington University in St. Louis have gained the first detailed insight into the way circadian rhythms govern global gene expression in Cyanothece, a type of cyanobacterium (blue-green algae) known to cycle between photosynthesis during the day and nitrogen fixation at night.

Marking milestones
DBBS marks 35th anniversary, 1,000th graduate
April 17,
2008 -- Washington University's Division of Biology and Biomedical Sciences (DBBS) celebrated two milestones May 1-2: its 35th anniversary and the graduation of its 1,000th student. The Division spans both the University's Danforth and Medical campuses to provide Ph.D. training programs in biology and the biomedical sciences. Established in 1973, the Division has become the national model for graduate education in biology and biomedical sciences because of its collaborative, interdisciplinary approach.

Tracing origins
Technique traces origins of disease genes in mixed races
April 8,
2008 -- A team of researchers from Washington University in St. Louis that includes Alan R. Templeton and the Israeli Institute of Technology (Technion) in Haifa has developed a technique to detect the ancestry of disease genes in hybrid, or mixed, human populations. The technique, called expected mutual information (EMI), determines how a set of DNA markers is likely to show the ancestral origin of locations on each chromosome.

Mimicking plant evolution proves fruitful
MSNBC.com
Jan. 11,
2008 -- By mimicking plant evolution, a team of Illinois researchers has improved upon nature's design to build a leafy energy-producing powerhouse — or at least a virtual one on a supercomputer. In a study published within the journal Plant Physiology, WUSTL biology and chemistry professor Robert Blankenship comments on the Illinois study.

Evolution Book Sees No Science-Religion Gap
The New York Times
and 6 others
Jan. 4,
2008 -- In 1984 and again in 1999, the National Academy of Sciences, the nation's most eminent scientific organization, produced books on the evidence supporting the theory of evolution and arguing against the introduction of creationism or other religious alternatives in public school science classes. Barbara A. Schaal, a vice president of the academy and an evolutionary biologist at WUSTL, comments on the third volume recently published.

Drought Can Destroy Diversity
LiveScience.com
Oct. 22,
2007 -- Scientists are more interested than ever in the effects of extreme climate swings, such as prolonged drought, because the computer models predict wilder extremes as one effect of the climate change now underway.
WUSTL biology professor and ecologist Jonathan Chase comments on his study that appeared in the Oct. 15 issue of the journal Proceedings of the National Academy of Sciences.

A leg up on efficiency
Los Angeles Times
and 3 others
March 19,
2007 -- THAT leggy friend who looks better than you in shorts also burns fuel more efficiently while walking or running, a researcher has found.
WUSTL biological anthropologist Herman Pontzer made this discovery while testing a mathematical model for calculating energy costs for locomotion.
His study is published in the February issue of the Journal of Experimental Biology.
