Scientists at Washington University School of Medicine in St. Louis have found definitive proof that some of the bacteria that plague women with urinary tract infections (UTIs) are entrenched inside human bladder cells.

The U.S. Food and Drug Administration (FDA) has approved Bystolic™ (nebivolol) for the treatment of hypertension, also known as high blood pressure. Hypertension affects approximately 72 million adults in the U.S. and 65 percent of patients diagnosed with hypertension have not reduced their blood pressure to an acceptable range (blood pressure <140/90 mmHg), underscoring the need for additional therapeutic options.

The Forest Service’s Eastern Forest Environmental Threat Assessment Center (EFETAC) recently launched its forest threats summary viewer, a tool that will provide images, threat distribution maps, additional forestry contact information, and brief descriptions about forest threats throughout the eastern U.S. EFETAC partnered with the University of North Carolina Asheville's National Environmental Modeling and Analysis Center (NEMAC) to develop the tool, which is available on EFETAC’s Web site, www.forestthreats.org.

A genetic mutation expands lesions in the aorta and promotes coronary atherosclerosis, more commonly known as hardening of the arteries, according to a study by Yale School of Medicine in Cell Metabolism.

Successful reproduction is critical to pass genes to the next generation. In sexually reproducing organisms, sperm enter the female with seminal proteins that are vital for fertility. In a new study published on Friday, December 14, 2007 in PLoS Genetics, researchers at Cornell University knocked down the levels of 25 seminal proteins individually in male fruit flies, testing the males’ abilities to modulate egg production, sperm storage and release, and the females’ post-mating behavior and physiology.

The ability of Argentine ants to change from carnivorous insect eaters to plant sap-loving creatures has helped these invasive social insects rapidly spread throughout coastal California, according to a new study, displacing many native insects and creating ant infestations familiar to most coastal residents.

People suffering from chronic mental or physical disabilities should not resort to a dolphin "healing" experience, warn two researchers from Emory University. Lori Marino, senior lecturer in the Neuroscience and Behavioral Biology Program, has teamed with Scott Lilienfeld, professor in the Department of Psychology, to launch an educational campaign countering claims made by purveyors of what is known as dolphin-assisted therapy (DAT).
