Bacteria's natural foe fights drug-resistant infections

Researchers at Rockefeller University have developed a novel approach to combating antibiotic-resistant infections by using a natural enzyme derived from tiny viruses that live inside bacteria. This enzyme can target and kill disease bacteria on the surface of cells, providing an alternative method for combating resistant pathogens.

Museums must play a bigger role in conservation

Natural history museums are critical forces for understanding and conserving the world's biological diversity. They must focus on conservation, make collections accessible, collect and disseminate information faster, engage local communities, and promote science-based advocacy to advance conservation goals.

Single enzyme may be linked to obesity

Research suggests that a single enzyme, 11beta hydroxysteroid dehydrogenase type 1 (11 beta HSD-1), is involved in the accumulation of visceral fat and metabolic symptoms. Increasing this enzyme's activity in fat cells leads to obesity, diabetes, and other diseases.

Folate supplements during pregnancy could protect against leukaemia

A population-based study in Western Australia suggests that folate and iron supplementation during pregnancy may reduce the risk of childhood acute lymphoblastic leukaemia by up to 60%. The protective effect was found to vary little with time of first use or duration of supplementation.

Studying, recreating sound in three dimensions

UC Davis researchers have captured the critical information needed to reproduce actual sounds as each listener perceives them. By analyzing changes in sound waves as they bounce off surfaces and ears, the team has developed personalized software and hardware for spatially accurate sound reproduction.

Benefits of government-mandated folic acid fortification greater than expected

Government-mandated folic acid fortification has improved red blood cell folate levels by more than expected, benefiting women of childbearing age and other populations. This increase is also linked to reduced homocysteine levels, a risk factor for vascular disease, heart attacks, strokes, and certain cancers.

The ecological consequences of 'promiscuous' boating

A study found that recreational boating can transport zebra mussels via entangled aquatic weeds, engine cooling systems, and live wells. The risk of spread to new water bodies is significant due to the high volume of transient boat traffic.

Study puts a damper on extent of new brain cell growth

A study published in Science found no new neurons in the neocortex of adult monkeys, contradicting previous reports. Researchers used advanced imaging techniques to analyze thousands of cells and conclude that mechanisms other than neurogenesis may be needed to understand brain function.

Enzyme mimetic reduces joint disease in rheumatoid arthritis model

Researchers developed a superoxide dismutase (SOD) mimetic that substantially reduced cartilage and bone erosion, as well as chronic inflammation, in a standard animal model. The SOD mimetic also significantly reduced elevated levels of pro-inflammatory cytokines TNF-α and IL-1β.

Gene triggers stem cell differentiation in the intestine

Scientists discover that the Math1 gene triggers the differentiation of three types of intestinal cells from stem cells, including goblet, enteroendocrine, and Paneth cells. This finding provides significant insights into the regulatory control of intestinal stem cells and their role in disease treatment.

Prediction of chronic fatigue syndrome and mood disorders after infection

A study of 250 primary-care patients found that infections like glandular fever can trigger chronic fatigue syndrome (CFS), while mood disorders are predicted by factors such as psychiatric history and social adversity. Early physical activity may help prevent or treat CFS after infectious mononucleosis.

Parents’ behavior affects development of low birth weight babies

A study found that mothers who perceive their small babies as difficult are less involved and responsive, leading to lower developmental test scores. However, infants born small for gestational age show a stronger link between early temperament and parental behavior, emphasizing the importance of sensitive interaction.
