University of Miami scientists find way to identify manmade biofuels in atmosphere

Researchers at the University of Miami have developed a technique to track urban atmospheric plumes using ethanol's isotopic signature, which can indicate the presence of manmade biofuels. The discovery has significant implications for understanding air pollution in urban areas and mitigating its effects on human health.

Cooked green vegetables, dried fruit, legumes, and brown rice associated with fewer colon polyps

A recent study published in Nutrition and Cancer found that high consumption of these foods was associated with a reduced risk of colon polyps by 33-40%, confirming the results of past studies. The protective effects may be due to their cancer-fighting agents, including fiber and detoxifying compounds.

Long periods of estrogen deprivation jeopardizes brain receptors, stroke protection

Researchers found that prolonged estrogen deprivation in aging rats reduces brain receptors for the hormone and its ability to prevent strokes. Early estrogen replacement therapy can forestall this damage. The study's results suggest a critical window for estrogen therapy, either right before or right after menopause.

Bilingual school counselors help narrow achievement gap

A recent study found significant improvements in reading and math scores for Spanish-speaking students who received a specialized bilingual/bicultural school counselor-led program, closing the traditional achievement gap. The evidence-based program positions school counselors to show their direct impact on student achievement.

How do you stop tasting?

Researchers at Monell Chemical Senses Center discover a protein called Serca3 that terminates bitter taste signals by removing calcium from taste cells. This finding may help explain why some people are supersensitive to certain tastes and could lead to the development of medicines to minimize unpleasant side effects.

BGU researchers develop webcam tool to improve office worker posture

A multidisciplinary team at Ben-Gurion University of the Negev developed a new training method using desktop webcams to improve ergonomic posture among office workers. The photo-training method provided effective short-term and long-term posture improvement, particularly for older workers and those with musculoskeletal pain.

Weakness in aging tied to leaky muscles

Research ties aging muscle weakness to leaky calcium channels in muscle cells. A drug already in Phase II clinical trials for heart failure may help repair these channels, restoring muscle function. The study's findings suggest a new approach to addressing age-related muscle wasting by focusing on muscle function rather than mass.

Study: Inexpensive method detects ALK rearrangement in lung cancer patients

A new, cost-effective method for detecting ALK rearrangement in non-small cell lung cancer patients has been developed. This approach is comparable to the established gold standard, fluorescence in situ hybridization (FISH), and could enable more patients to access potentially life-saving crizotinib therapy.
