A world-first study led by University of Sydney has found that Australians aged 18-40 years who were regular users of sunscreen in childhood reduced their risk of developing melanoma by 40 percent, compared to those who rarely used sunscreen.
The components of the immune system that trigger allergic reactions may also help protect the skin against cancer, suggest new findings.
Contact with greenspace is known to have beneficial effects for mental health. A new study by the Barcelona Institute for Global Health (ISGlobal) suggests that it may also play a positive role against cognitive decline in elderly. In particular, this research published in Environmental Health Perspectives shows that the loss in cognitive functions expected as part of the aging process is slightly slower in people who live in greener neighborhoods.
California has one of the world's most progressive cap-and-trade designed to reduce greenhouse gases. Yet in disadvantaged communities, emissions of those pollutants has actually gone up.
Researchers' goal is to improve radiation testing through gene expression.
The American Chemical Society journal Environmental Science & Technology featured research by Carla Ng, assistant professor of civil and environmental engineering at Pitt's Swanson School of Engineering, on the cover of its June 19 issue. Dr. Ng tracked the presence of a class of synthetic flame retardants called polybrominated diphenyl ethers (PBDEs), which were once a popular additive to increase fire resistance in consumer products such as electronics, textiles, and plastics.
Students in dormitories without air conditioning performed worse on cognitive tests during a heat wave compared with students living in air-conditioned dorms. This is the first field study to show the detrimental cognitive effects of a heat wave in a group of young healthy individuals.
New Yorkers are getting heavier. And, like people across the country, many have difficulty sleeping and are suffering from depression. Diabetes rates in NYC remain high and racial and ethnic disparities persist.
In the eastern US, risk of contracting Lyme disease is higher in fragmented forests with high rodent densities and low numbers of resident fox, opossum, and raccoons. These are among the findings from an analysis of 19 years of data on the ecology of tick-borne disease in a forested landscape, recently published in the journal Ecology.
Exposure to cold prior to conception causes the resulting offspring to have more brown adipose tissue, which protects against excess weight and metabolic disorders. Scientists studying mice have discovered that this information is passed on by the sperm, and there is a similar correlation in humans.
