Red blood cell variation linked to natural malaria resistance
May 19, 2017 10:23 AM - University of Oxford

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.

Mosquitoes that spread Zika virus could simultaneously transmit other viruses
May 19, 2017 10:08 AM - Colorado State University

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.

During heat waves, urban trees can increase ground-level ozone
May 17, 2017 04:48 PM - American Chemical Society

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.

Super hearing: University of Toronto scientists study fly to develop better hearing aids
May 17, 2017 08:21 AM - University of Toronto

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.”

Researchers make waves in the ultrasound world
May 16, 2017 08:05 AM - Ryerson University

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.

Diesel vehicles produce 50 per cent more nitrogen oxide than originally thought
May 15, 2017 11:41 AM - University of York

A study, published in Nature, has shown that laboratory tests of nitrogen oxide emissions from diesel vehicles significantly underestimate the real-world emissions by as much as 50 per cent.

The research, led by the International Council on Clean Transportation and Environmental Health Analytics, LLC., in collaboration with scientists at the University of York’s Stockholm Environment Institute (SEI); University of Colorado; and the International Institute for Applied Systems Analysis, examined 11 major vehicle markets representing more than 80% of new diesel vehicle sales in 2015.
