Extremely low levels of the compound in marijuana known as delta-9-tetrahydrocannabinol, or THC, may slow or halt the progression of Alzheimer’s disease, a recent study from neuroscientists at the University of South Florida shows. Findings from the experiments, using a cellular model of Alzheimer’s disease, were reported online in the Journal of Alzheimer’s Disease. Researchers [...]

As Ebola Rages, Controlling The Deadly Spread

The outbreak of the deadly Ebola virus in West Africa has Americans concerned about their health and safety. The World Health Organization (WHO) has declared an international public health emergency in an effort both to contain the spread of the virus, which is considered 90% fatal, and to warn people about its seriousness. A WHO [...]

Fungus Deadly To AIDS Patients Found To Grow On Trees

This false-color electron microscope image catches the fungus Cryptococcus gattii in the act of producing its infectious spores. The club-shaped blue structure is a reproductive organ called the basidium, which projects off the fungus body like an apple off a tree. The spores are colored yellow, and are like seeds that can give rise to a new organism.

Researchers have pinpointed the environmental source of fungal infections that have been sickening HIV/AIDS patients in Southern California for decades. It literally grows on trees. The discovery is based on the science project of a 13-year-old girl, who spent the summer gathering soil and tree samples from areas around Los Angeles hardest hit by infections [...]

Laser-Based Glucose Monitor Could End Pin Pricks For Diabetics

A new system developed by Princeton researchers uses a laser to allow diabetics to check their blood sugar without pricking their skin. Members of the research team included, from left, Sabbir Liakat, a graduate student in electrical engineering; Claire Gmachl, the Eugene Higgins Professor of Electrical Engineering; and Kevin Bors, who graduated in 2013 with a degree in electrical engineering.

Researchers have developed a way to use a laser to measure people’s blood sugar, and, with more work to shrink the laser system to a portable size, the technique could allow diabetics to check their condition without pricking themselves to draw blood. “We are working hard to turn engineering solutions into useful tools for people [...]

Electronic Alerts Significantly Reduce Catheter-Associated Urinary Tract Infections

A Penn Medicine team has found that targeted automated alerts in electronic health records significantly reduce urinary tract infections in hospital patients with urinary catheters. In addition, when the design of the alert was simplified, the rate of improvement dramatically increased. The alerts help physicians decide whether their patients need urinary catheters in the first [...]
