A study of over 17,150 male physicians found that taller men and those with higher waist-to-hip ratios were at increased risk of developing cataracts. The authors suggest a possible genetic link to height and abdominal adiposity as contributing factors.
A study by Dr. Adam Drewnowski suggests that using Mediterranean cuisine techniques can help overcome bitterness in vegetables, revealing potential health benefits.
Researchers found that interrupting therapy in rhesus macaques with HIV led to a vigorous immune response and controlled virus levels. The study's results suggest patients might be able to take fewer drugs, stimulating the immune system to better control the virus.
Vitamin D deficiency is common among elderly community-living women, associated with higher levels of disability. Elderly black women are at significant risk due to lower cutaneous synthesis of vitamin D3, while obesity is linked to deficiency in less-disabled women.
A pooled analysis of randomized controlled trials found that zinc supplementation reduced the duration of diarrheal episodes in infants in developing countries by 16% overall. The study also showed a significant reduction in treatment failure or death rates, particularly among malnourished male children.
A study found that household exposure to passive smoke is associated with lower serum concentrations of carotenoids and other micronutrients in non-smokers. This depletion may be due to cigarette smoke exposure, rather than shared inadequate diets, suggesting a possible causal link between passive smoking and nutrient deficiencies.
Eight-month-old babies demonstrate ability to bind attributes to form a whole object, as seen in the Kanizsa Square test. This skill, previously thought to develop later in childhood, reveals insights into early infant development and cognitive processing.
Researchers at Sandia National Laboratories discovered that dancing tin crystals can convert chemical energy into forward motion, overcoming friction between tin and the copper surface. This phenomenon could lead to surprisingly efficient nanomotors that can be controlled externally and refueled.
