A study published by University of Georgia researchers reveals a vast array of novel bacteria in Carolina bays, many of which remain unclassified. The discovery highlights the importance of the microbial world in shaping biodiversity.
Scientists at Sandia National Laboratories and France Telecom have developed a prototype memory-retention device that uses embedded protons to preserve information. The 'protonic' device is inexpensive, low-powered, and simple to fabricate, and can retain data even when power is turned off.
A 30-year follow-up study found that men who ate about 35 grams of fish per day had a significantly lower risk of dying from a heart attack than those who did not eat fish. The findings held true after accounting for various demographic and health factors, supporting the view that eating fish protects against heart attacks.
A Johns Hopkins researcher proposes that a tiny jet of liquid inside a bubble could be the cause of sonoluminescence, releasing energy as light. The theory suggests that the fluid's fracture creates a foothold for noble gas atoms to initiate luminescence.
A recent Penn State study reveals that older adults have a decreased ability to cool their bodies and pump blood efficiently in extreme heat, increasing the risk of cardiovascular problems. Even healthy older individuals with heart disease should take precautions to stay cool and minimize strain on their hearts.
A potent chemokine, AOP-RANTES, has been shown to inhibit HIV-1 entry into macrophages and lymphocytes at the nanomolar level. Researchers believe this could lead to a new treatment approach for HIV/AIDS by targeting host cells to prevent viral entry.
Astronomers have detected a giant solar eruption with particles hurtling towards the Earth. The NASA POLAR spacecraft will monitor the Earth's aurora in real-time, capturing enhanced activity on Wednesday afternoon.
Maintaining a surgical patient's normal body temperature has been shown to reduce infections, speed healing and shorten hospital stays. Results of a clinical trial suggest a 55% risk reduction in cardiac complications when near-normal body temperatures are maintained.
Researchers used non-invasive functional magnetic resonance imaging to test the theory that the prefrontal cortex stores information in working memory. The study found sustained activity in the prefrontal cortex, suggesting it plays a key role in maintaining information.
Researchers at Duke University found that pre-treating insulin-producing pancreatic islet cells with glutathione preserves their ability to regulate sugar levels. This advance could overcome a major hurdle in the transplantation of islet cells into humans as a treatment for diabetes.
