The Biology Club and the Department of Biology are co-sponsoring a photo contest for undergraduate Biology majors! The top three award recipients will receive prizes, as well as recognition at the Undergraduate Awards Ceremony. ...
Researchers visualize complex pigment mixtures in living cells
In a technical advance that could allow researchers to watch cells as they act during the process of photosynthesis, scientists have developed a method that extends the power of fluorescence-mediated bio-imaging to see discrete pigments ...
Solvent not included
I’m interested that Ruth Lynden-Bell is thanked for discussions; Ruth has pioneered this notion of a kind of counterfactual exploration of water’s role in structural biology, as a way of investigating the notion of ‘fine-tuning’ of ...
Study uncovers cause of flu epidemics
The exchange of genetic material between two closely related strains of the influenza A virus may have caused the 1947 and 1951 human flu epidemics, according to biologists. The findings could help explain why some strains cause major ...
National Zoo scimitar-horned oryx going into the wild
These four scimitar-horned oryx are among the nine that were returned in December 2007 to Tunisia, where they have been extinct since the late 1970s. A male oryx from the Smithsonian's National Zoo's Conservation and Research Center in ...
Tiny polyps need 2 kinds of carbon to survive coral bleaching
How well ocean reefs recover from the growing damage caused by warming sea temperatures depends both on how much the tiny coral polyps can eat, and how healthy they can keep the microscopic algae that live inside their bodies.

Conference on Skeletal Biology and Medicine (2nd : 2007 : New York, NY)
Viruses evolve to play by host rules, according to University of ...
Biologists at the University of Pennsylvania and Harvard University have examined the complete genomes of viruses that infect the bacteria E. coli, P. aeruginosa and L. lactis and have found that many of these viral genomes exhibit ...
Irritating smells alert special cells, NIH-funded study finds
If you cook, you know. Chop an onion and you risk crying over your cutting board as a burning sensation overwhelms your eyes and nose. Scientists do not know why certain chemical odors, like onion, ammonia and paint thinner, ...
