Researchers at UT Southwestern Medical Center discovered that alpha-lipoic acid reduces oxidative stress and blood levels of bad cholesterol. The compound may improve blood-glucose control and has potential implications for aging and heart disease prevention.
Researchers at the University of Michigan have identified a key mechanism by which some viruses, including Kaposi's sarcoma-associated herpesvirus, can hide in human cells for extended periods. The study reveals that a protein called LANA binds to host chromosomes, allowing viral DNA to remain dormant until the immune system is weakened.
Jobaria tiguidensis, a 70-foot-long plant-eater from the Cretaceous period, has been discovered with nearly complete skeletons of an adult and juvenile. The species' unique spoon-shaped teeth and short neck set it apart from other sauropods.
A study by University of Washington researchers found that individuals with aggressive and low dependency personalities are at higher risk for recurrent major depression. The findings suggest that patients who enjoy activities and have moderate social support are less likely to relapse.
A team of scientists at CIIT published an up-to-date risk assessment for cancer from inhaled formaldehyde, integrating the latest mechanistic knowledge and incorporating a two-stage clonal growth model. The new model predicts lower risks for environmental and workplace exposures compared to earlier models.
Researchers are developing a new sandwich structure made from lightweight honeycomb core and curved composite panels, which can contribute to faster boats and fuel-efficient airliners. The key attribute of the material is its light weight, resulting from the honeycomb-like design of the inner core.
