Researchers found that waddling actually helps penguins save energy by using their leg muscles more efficiently. They also discovered that penguins are not inefficient walkers because of their gait, but rather due to the short length of their legs.
A survey of over 6,700 individuals found that smoking and heavy drinking are linked to poorer food choices and increased health risks. The study suggests that targeting multiple risk factors simultaneously is crucial for effective health promotion.
Children of heavy smokers are at risk of inadequate asthma treatment due to decreased parental awareness and reluctance to quit smoking. Research found that the more heavily parents smoked, the fewer visits were made to healthcare services for asthma symptoms.
Researchers found a 2% survival benefit among patients undergoing colon cancer surgeries at high-volume hospitals compared to lower volume facilities. The study examined over 28,000 Medicare beneficiaries and controlled for age, sex, and cancer stage.
Researchers found that obese individuals were twice as likely to be diagnosed with asthma, but not more responsive airways. Underweight individuals, on the other hand, experienced increased airway responsiveness and reduced lung function.
A 20-year follow-up study of gifted students from 1980 reveals that women chose careers with more people interaction and less physical sciences. Despite higher male incomes, both sexes valued self-esteem equally.
Researchers found that mitochondrial organization in eggs is crucial for developing embryos. The study showed that the symmetry or asymmetry of mitochondria-carrying microtubules may determine an embryo's viability and success.
Scientists have discovered a vaccine that may prevent and treat Alzheimer's by blocking the production of toxic amyloid ß peptides, which accumulate in the brain and cause dementia. The vaccine has shown promise in removing amyloid plaques and preventing learning impairment in transgenic mice, paving the way for potential human trials.
A University of Florida study finds that New York, Chicago, and Washington-Baltimore lead the nation in bandwidth availability, while Florida's top cities, including Orlando, fall behind. The disparity puts Florida companies at a competitive disadvantage, hindering business growth and consumer access to high-speed Internet services.
A large case-control study found no association between cell phone usage and the development of primary brain cancer in a cohort of 891 participants. The study, published in JAMA, analyzed data from patients with primary brain cancer and controls without cancer, finding no correlation between cell phone use and brain cancer risk.
