Everything under the sun you need to know about protecting your skin.

With summer right ahead, you may be planning to relax poolside or at the beach. But enjoying summer's longer and sunnier days outdoors means your skin is vulnerable to sunburn. Unless you take the right precautions, sun exposure (even if you don't get scorched) can damage your skin, causing wrinkles, age spots and even skin cancer.

A University of Oklahoma Civil Engineering and Environmental Science Professor Robert Nairn and his co-authors have conducted a collaborative study that suggests exposure to trace metals from potatoes grown in soil irrigated with waters from the Potosi mining region in Bolivia, home to the world’s largest silver deposit, may put residents at risk of non-cancer health illnesses.

University of Texas Medical Branch at Galveston scientists have unlocked mysteries of how the Ebola virus hampers the body’s natural defenses to speed the rate of infection and its accompanying lethal disease, according to a new report in PLOS Pathogens. The study was conducted in collaboration with the University of Washington and The National Institute of Allergy and Infectious Diseases.

A new study has found that children, especially boys, whose mothers were exposed to higher levels of outdoor particulate air pollution at the same time that they were very stressed were most likely to develop asthma by age six. The study was presented at the 2017 American Thoracic Society International Conference. 

The team, led by senior investigator Rosalind Wright, MD, MPH, co-director of the Institute for Exposomics Research at the Icahn School of Medicine at Mount Sinai, conducted this study because of their overarching interest in understanding how these and other environmental factors interact to produce respiratory health disparities.

High levels of air pollution over time may get in the way of a good night’s sleep, according to new research presented at the ATS 2017 International Conference.

“Prior studies have shown that air pollution impacts heart health and affects breathing and lung function, but less is known about whether air pollution affects sleep,” said lead author Martha E. Billings, MD, MSc, assistant professor of medicine at the University of Washington. “We thought an effect was likely given that air pollution causes upper airway irritation, swelling and congestion, and may also affect the central nervous system and brain areas that control breathing patterns and sleep.”

A study from the Wellcome Trust Sanger Institute, the Wellcome Trust Centre for Human Genetics and their collaborators have identified a genetic rearrangement of red blood cell glycophorin receptors that confers a 40 per cent reduced risk from severe malaria.

A new study led by Colorado State University researchers found that Aedes aegypti, the primary mosquito that carries Zika virus, might also transmit chikungunya and dengue viruses with one bite. The findings shed new light on what’s known as a coinfection, which scientists said is not yet fully understood and may be fairly common in areas experiencing outbreaks.

Planting trees is a popular strategy to help make cities “greener,” both literally and figuratively. But scientists have found a counterintuitive effect of urban vegetation: During heat waves, it can increase air pollution levels and the formation of ozone. Their study appears in ACS’ journalEnvironmental Science & Technology.

Previous research has shown that planting trees in cities can have multiple benefits, including storing carbon, controlling storm water and cooling areas off by providing shade. This has spurred efforts in cities across the U.S. and Europe to encourage the practice. However, it’s also known that trees and other plants release volatile organic compounds, or VOCs, that can interact with other substances and contribute to air pollution. And when it’s hot, plants release higher levels of VOCs. Galina Churkina and colleagues wanted to investigate what effects heat waves and urban vegetation might have on air pollution.

Ormia ochracea's sense of directional hearing is second to none in the animal kingdom.

“These flies have highly specialized ears that provide the most acute directional hearing of any animal,” says Andrew Mason, an associate professor of biology at U of T Scarborough.  “The mechanism that makes their hearing so exceptional has even led to a range of bio-inspired technology, like the mini-directional microphones used in hearing aids.”

A team of Ryerson researchers, led by Scott Tsai, have developed a new method to create the uniformly minuscule microbubbles most desirable for use in ultrasound imaging.
