After decades of public safety campaigns focused on drinking and driving, it may be time to focus on the seventh leading cause of injury-related death, according to Bureau of Occupational Health and Injury Prevention at New York State Department of Health and Columbia University scholars looking at New York State.
Child fitness levels are falling at an even faster rate than first feared - and it has nothing to do with obesity, according to a new study. Of more than 300 pupils aged between 10 and 11 who took part, the researchers expected that children with a lower BMI would do better than the heavier children they measured six years ago.But the follow-up to a 2009 study showed child fitness declined by 8% over the previous ten years - yet the children they tested were actually thinner than those measured in 2008.
There is no longer any doubt: We are entering a mass extinction that threatens humanity's existence, according to a rather ridiculous claim by doomsday prophet Professor Paul Ehrlich, the same author of the Population Bomb who has been saying this same thing since the 1960s. Ehrlich and fellow hysterics Anthony D. Barnosky of the University of California at Berkeley, Andrés García of Universidad Autónoma de México, Robert M. Pringle of Princeton University and Todd M. Palmer of the University of Florida, say there are threatened species, too many humans, and issues with habitat.
New, ultra-high-field magnetic resonance images (MRI) of the brain provide the most detailed images to date to show that while the brain shrinks with age, brain cell density remains constant.
The images of cognitively normal young and old adults provide the first evidence that in normal aging, cell density is preserved throughout the brain, not just in specific regions, as previous studies on human brain tissue have shown. The findings also suggest that the maintenance of brain cell density may protect against cognitive impairment as the brain gradually shrinks in normal aging.
Doctors often misdiagnose zinc deficiency, and seem to be unaware of the impact of excess zinc on the body, according to a small audit of clinical practice.
Zinc is an essential trace element that is required in daily quantities of 5.5 to 9.5 mg for men, and 4 to 7 mg for women. But zinc supplements are usually only available in formulations of 45 or 50 mg. The US recommended tolerable limit is 40 mg/day.
Working women are "leaning in" and supporting more females in leadership roles, but a new study finds that having a female manager doesn't necessarily equate to higher salaries for female employees.
Instead, women can sometimes take an earnings hit relative to their male colleagues when they go to work for a female manager.
Melanoma patients with high levels of a protein that controls the expression of pro-growth genes are less likely to survive, according to a study led by researchers at Icahn School of Medicine at Mount Sinai and published online in the journal Molecular Cell.
The research team found that the protein, called H2A.Z.2, promotes the abnormal growth seen in melanoma cells as they develop into difficult-to-treat tumors. H2A.Z.2 is part of the chromosome structure that packages genes, and has the ability to switch them on off. Having high levels of this protein aberrantly activates growth-promoting genes in melanoma cells.
Often referred to as the "body clock", circadian rhythm controls what time of day people are most alert, hungry, tired or physically primed due to a complex biological process that is not unique to humans. Circadian rhythms, which oscillate over a roughly 24-hour cycle in adaptation to the Earth's rotation, have been observed in most of the planet's plants, animals, fungi and cyanobacteria, and are responsible for regulating many aspects of organisms' physiological, behavioral and metabolic functions.
When a new type of drug or therapy is discovered, double-blind randomized controlled trials (DBRCTs) are the gold standard for evaluating them. These trials, which have been used for years, were designed to determine the true efficacy of a treatment free from patient or doctor bias, but they do not factor in the effects that patient behaviors, such as diet and lifestyle choices, can have on the tested treatment.
With warming summer temperatures across Alaska, white spruce tree growth in Interior Alaska has declined to record low levels, while the same species in Western Alaska is growing better than ever measured before.
The findings are the result of a study led by University of Alaska Fairbanks School of Natural Resources and Extension researcher Glenn Juday, Claire Alix of the University of Paris 1 Pantheon-Sorbonne, and Tom Grant, formerly an adjunct faculty member at UAF. Their findings were recently published online by the journal Forest Ecology and Management.
Political partisanship is rooted in affective, physiological processes that cause partisans to toe the party line on policies and issues, regardless of policy content, according to a new paper.
Social psychologists have said that party identifiers are more inclined to agree with policy proposals that are proposed by their own party, independent of the content of the proposal. If the same proposal is issued by a competing party, they will be inclined to respond negatively to it. In other words, liberals and conservatives don't care about what is best for society, it has to be filtered through their beliefs to be legitimate.
Partnerships with multinational companies like Coca-Cola in child health programs can work to help save lives but decades of well-funded public relations campaigns against corporations by NGOs has turned letting companies fund programs into an ethical minefield.
ColaLife, a charity formed by British couple Simon and Jane Berry, worked with Coca-Cola to learn about the distribution channels the company uses in developing countries. With this knowledge, they devised a system to ensure life saving treatments reach children with diarrhea in remote parts of Zambia.
In a new study, older women who lived in places with higher air pollution had significantly reduced white matter in the brain. For the study, a research team took brain MRIs of 1403 women who were 71 to 89 years old and used residential histories and air monitoring data to estimate their exposure to air pollution in the previous 6 to 7 years.
The findings suggest that ambient particulate air pollutants may have a deleterious effect on brain aging.
