Prairie dogs, once abundant in the Rocky Mountains and Great Plains, have been decimated in recent decades by plague -- a virulent bacterial disease spread by fleas.
Plague outbreaks periodically sweep through large prairie dog towns with thousands of inhabitants, killing virtually the entire... Read More
GlaxoSmithKline PLC (GSK) Wednesday said a method of killing bacteria already resistant to existing treatments has been found which could help scientists develop new antibiotics to tackle bacteria responsible for many hospital and community-acquired infections.
The research results, published... Read More
Hematopoietic stem cells provide the body with a constant supply of blood cells, including the red blood cells that deliver oxygen and the white blood cells that make up the immune system. Hematopoietic - or blood - stem cells must also make more copies of themselves to ensure that they are pres... Read More

The type III secretion system allows Salmonella typhimurium to get the goods into your cells: bacterial effector proteins travel through the connected inner and outer membrane rings and down a protruding needle-like tube, into the host cell. Despite the importance of S. typhimurium as a human p... Read More

On the long and difficult road toward a carbon-neutral source of transportation fuels, the U.S. Department of Energy (DOE) is pursuing a diversified approach. This effort involves exploring a range of potential new fuel sources in nature: from plants that may serve as cellulosic feedstocks—fast... Read More
Occasionally, researchers stumble across something extraordinary in a system that has been studied for decades.
Ryan Kerney of Dalhousie University in Halifax, Nova Scotia, Canada, did just that while looking closely at a clutch of emerald-green balls--embryos of the spotted salamander (Ambys... Read More
Can the disease-causing capabilities of an organism be predicted from its DNA? This was a key question faced by a 13-member committee of the National Research Council (NRC). It was trying determine what it would take to develop a government system that spots bioweapons in the making by screening... Read More
