New Light Shed On Hybrid Animals
What began more than 50 years ago as a way to improve fishing bait in California has led a researcher to a significant finding about how animal species interact and that raises important questions about conservation. In the middle of the 20th century, local fishermen who relied on baby salamanders as bait introduced a new species of salamander to California water bodies. These Barred Tiger salamanders came into contact with the native California Tiger salamanders, and over time the two species began to mate. Plants, Too, Have Ways To Manage Freeloaders
Many organisms pair off in symbiotic relationships, exemplified by the mutualism of legumes and nitrogen-fixing bacteria in the soil. But how does one organism prevent exploitation by the other? A recent study by UC Berkeley ecologists shows that lupines, a common, flowery legume, do have a way to manage the bacteria that infect their roots. They appear to select bacteria good at sharing nitrogen by limiting the size of nodules housing bacteria that don't share. Inheritance, Smoking Spawn Mysterious And Deadly Lung Disease
An incurable, deadly lung disorder, "idiopathic interstitial pneumonia"(IIP), whose causes were mysterious arises from a combination of a genetic predisposition and damage due to inhaled chemicals, notably from cigarette smoking, Duke University Medical Center researchers have found. Engineer Develops Laser Technologies To Analyze Combustion, Biofuels
Mechanical engineers are using laser technology to develop advanced sensors capable of analyzing the combustion inside engines, power generators and heating systems. The sensors will be used to study -- and potentially improve -- the combustion of alternative fuels. Connection Between Job Loss And Poor Health Confirmed
Employees who lose their jobs because of their health suffer more significant depression and detrimental health outcomes than people who lose their jobs for non-health reasons, new research shows. The Center for Education and Research in Retailing

Procedure May Save Patients From Developing Diabetes
Transplanting a patient's own islet cells is a simple procedure that can save pancreatitis sufferers from developing diabetes, but many are unaware the therapy exists. The University of Illinois Medical Center at Chicago is the only hospital in the state and one of only a few in the country to offer patients autologus islet cell transplantation.
