A new study out of Harvard University reveals that the protective stratospheric ozone layer above the central United States is vulnerable to erosion during the summer months from ozone-depleting chemical reactions, exposing people, livestock and crops to the harmful effects of UV radiation.

Powerful storm systems common to the Great Plains inject water vapor that, with observed temperature variations, can trigger the same chemical reactions over the central United States that are the cause of ozone loss over the polar regions, according to a new paper published in the Proceedings of the National Academy of Sciences.

Engineering researchers at The University of Texas at Austin have developed the most detailed and extensive local map of air pollution ever produced for an urban area, using specially equipped Google Street View cars to measure air quality on a block-by-block basis. This new hyper-local mobile approach to measuring air quality, which reveals that air pollution can vary dramatically even within a single city block, could address major air quality monitoring gaps worldwide.

A new study led by Northern Illinois University geography professor Wei Luo calculates the amount of water needed to carve the ancient network of valleys on Mars and concludes the Red Planet’s surface was once much more watery than previously thought.

“Online technologies have transformed communications in practically every aspect of our lives, and now we’re seeing they’re also allowing patients to take an active role in their care and get immediate access to their care provider,” said ASCO Expert Harold J. Burstein, MD, PhD, FASCO. “It’s impressive that something as simple as this not only improves quality of life, but in this case, helps patients live longer. I think we’ll soon see more cancer centers and practices adopting this model.”

Research presented at the ASM Microbe 2017 meeting by Bryan Sanchez of California State University–Northridge in Northridge, Calif., show that antibiotic-resistant bacteria are present in many ready-to-eat foods such as fresh produce and dairy products and may serve as a source of human exposure to antibiotic-resistant bacteria. About 2 million people become infected with antibiotic resistant-bacteria annually in the United States, resulting in over $35 billion in additional health care costs. Examining potential ways that humans can be exposed to antibiotic-resistant bacteria can help in understanding how to counter the threat.

Simon Fraser University researchers are investigating why some older Canadians living with multiple chronic health conditions maintain their resiliency.

Professor Andrew Wister, director of SFU’s Gerontology Research Centre, is SFU’s principal investigator for the multi-university Canadian Longitudinal Study on Aging (CLSA). He leads one of 25 research teams benefiting from a share of $1.7 million in CLSA catalyst grants, funded by the Canadian Institutes of Health Research (CIHR), announced today.

The rift in the Larsen C ice shelf in Antarctica has grown by 17km in the last few days and is now only 13km from the ice front, indicating that calving of an iceberg is probably very close, Swansea University researchers revealed after studying the latest satellite data.

A Queen’s University researcher has led an international team of scientists to the discovery of a new material, which could finally bring an end to the misery of cracked smartphone and tablet screens.

A computer's ability to predict a patient's lifespan simply by looking at images of their organs is a step closer to becoming a reality, thanks to new research led by the University of Adelaide.

The startling extent to which man-made pollution is devastating China’s vital ecosystem’s ability to offset damaging carbon emissions has been revealed.
