“The current methods of restoring these sites are not as cost efficient or energy efficient as they could be, and can cause more environmental disruption,” said Susan Kaminskyj, a professor in the Department of Biology. “Our biotech innovation should help to solve this type of problem faster and with less additional disturbance.”Kaminskyj led a research…

For the first time, evidence of the zebra chip pathogen has been found in potato fields in southern Alberta, but the University of Lethbridge’s Dr. Dan Johnson cautions against panic.“So far, the zebra chip pathogen has appeared in only small numbers of potato psyllids,” says Johnson, a biogeography professor and coordinator of the Canadian Potato…

Wrap your mind around this: Neutron stars, the collapsed cores of once-large stars, are thought to be so dense that a teaspoon of one would weigh more than Mount Everest.These are the kind of amazing astrophysical features that help fuel the research interests of Professor John Bally of the Department of Astrophysical and Planetary Sciences,…

A new species of bird from the heart of Peru remained undetected for years until researchers identified it by its unique song.

Rising sea levels and human activities are fast creating a "worst case scenario" for Native Americans of the Mississippi Delta who stand to lose not just their homes, but their irreplaceable heritage, to climate change.

Delivering news about end-of-life issues is one of the most difficult tasks clinicians encounter in medical practice. Researchers from the Texas Medical Center on behalf of the ETHICS study investigators, in Houston, Texas, aimed to assess how prepared health-care providers feel in communicating end-of-life issues and determining if proper training had been given to health-care…

Northwestern Medicine scientists have used an innovative gene editing technique to identify the genes that may lead to Parkinson’s disease after exposure to paraquat, a commonly-used herbicide.

China is rapidly expanding its solar power supply, hoping to meet 10 percent of the nation’s electricity needs with solar energy by 2030. But there’s a problem: Severe air pollution is blocking light from the sun, significantly reducing China’s output of solar energy, particularly in the northern and eastern parts of the country.

In 1995, the Governing Council of the United Nations Environment Program called for a united, global effort to reduce persistent organic pollutants (POPs) — synthetic chemicals such as PCBs, DDT, and dioxins. The compounds were known to persist and accumulate far from their sources, polluting the environment and causing adverse health effects in humans.

Tuna is one of the most ubiquitous seafoods. It can be eaten from a can or as high-end sashimi and in many forms in between. But some species are over-fished and some fishing methods are unsustainable. How do you know which type of tuna you’re eating?Some tuna is certified as sustainably caught by groups such…
