Researchers have discovered how bacteria evade antibiotics by exploiting a protein complex with a diverse binding site. The findings may lead to the development of new antibiotics that can bypass this pump, allowing drugs to kill bacteria. Alternative strategies, such as disabling the pump, are also being explored.
The Bristol Bay sockeye stock is a biocomplex system comprising hundreds of discrete populations, each with local adaptations that stabilize the system. Management strategies focus on networks of habitat rather than just protecting today's strongest runs.
Researchers at Oregon State University have developed a new approach to managing natural resources using advanced mathematics. By applying mathematical models to predict the behavior of complex ecosystems, they aim to improve conservation efforts and address issues such as fisheries management and disease spread.
The RESPeRATE TM device is gaining acceptance for its non-drug treatment of hypertension, with a new chapter in the American Heart Association's textbook supporting its therapeutic effect. The device works by reducing sympathetic outflow and peripheral resistance, leading to blood pressure reductions.
Researchers discovered that humanin binds to Bax, preventing its targeting to mitochondria and blocking apoptosis. This finding suggests novel therapeutic approaches to prevent diseases associated with Bax activation.
Scientists at Johns Hopkins will pursue novel biological therapies to prevent abnormal heart rhythms and sudden death in patients recovering from heart attacks. They will also use modern imaging techniques to define the features of the heart posing the greatest risk for life-threatening arrhythmias.
Marine biologist Sara Lourie identifies a new species of pygmy seahorse, Hippocampus denise, found in tropical waters of the western Pacific Ocean. The diminutive fish, averaging 16mm in length, may be safe from over-exploitation due to its camouflage abilities.
Researchers at Oregon State University discovered that ground raisins can inhibit bacterial growth in beef jerky as effectively as sodium nitrite, a common preservative. The study found that adding raisins to jerky reduces fat content, increases antioxidants and fiber, making it a more appealing option for consumers on low-sodium diets.
Researchers found exponential killing of tuberculosis bacteria was more rapid with isoniazid, followed by rifampin's dominance. A study of acute monocytic leukemia revealed rapidly progressive respiratory distress, highlighting the need for early ICU admission and management.
Researchers have discovered that mouse models of Alzheimer's disease duplicate their DNA and make an attempt at cell division, just like human nerve cells. This suggests that the underlying mechanism of cell death is the same in both species, potentially making these model systems more suitable for testing experimental therapies.
