Scientists have devised a method for predicting how rising global temperatures are likely to affect the severity of diseases mediated by parasites. Their method can be applied widely to different host-pathogen combinations and warming scenarios, and should help to identify which infectious diseases will have worsened or diminished effects with rising temperatures.

For years, scientists have been inspired by nature to innovate solutions to tricky problems, even oil spills — manmade disasters with devastating environmental and economic consequences. A new USC study takes a cue from leaf structure to fabricate material that can separate oil and water, which could lead to safer and more efficient oil spill clean-up methods.

Most of us are used to turning on a tap and water coming out. We rarely question whether this will happen or whether the water is clean enough to bathe in or drink. Though the process of maintaining water quality is practically invisible to most of us, removing bacteria and contaminants from water requires a lot of effort from both humans and treatment systems alike.

Although scientists warn that urgent action is needed to stop climate change, public engagement continues to lag. Many social scientists say people are hesitant to act on climate change because, especially in Western industrialized countries like the U.S., it feels like such a distant threat.

U.S. Geological Survey scientists have developed the first laboratory test that can pick up traces of manatees’ genetic material in the waterways where they live.  Using a water sample collected in the field, the innovative environmental DNA test can reveal whether one or more of the elusive marine mammals has been in the area within the past month.

This year’s unexpectedly aggressive flu season reminds everyone that although the flu vaccine can reduce the number of people who contract the virus, it is still not 100 percent effective. Researchers report that a tweak to a small-molecule drug shows promise for future production of new antiviral therapies that could help patients, regardless of the strain with which they are infected.

The world drinks a lot of wine, and that means a lot of grapes are consumed every year. But not every part of the grape ends up in the bottle. Seeds, stalks and skins — roughly a quarter of the grapes —- are typically discarded in landfills as waste. But now, researchers say they have found some useful commercial applications, such as prolonging the shelf life of fatty foods, for these wine leftovers.

Summers in the city can be extremely hot — several degrees hotter than in the surrounding countryside. But recent research indicates that it may not have to be that way. The systematic replacement of dark surfaces with white could lower heat wave maximum temperatures by 2 degrees Celsius or more. And with climate change and continued urbanization set to intensify “urban heat islands,” the case for such aggressive local geoengineering to maintain our cool grows.

More Arctic sea ice is entering the North Atlantic Ocean than before, making it increasingly dangerous for ships to navigate those waters in late spring, according to new research led by the University of Manitoba.

Three University of Victoria researchers have been awarded a total $935,000 in federal funding to study the impact of underwater noise on endangered southern resident killer whales and the chinook salmon they depend on for almost 80 per cent of their diet.
