A team of chemists in Canada has developed a way to process metals without using toxic solvents and reagents. The system, which also consumes far less energy than conventional techniques, could greatly shrink the environmental impact of producing metals from raw materials or from post-consumer electronics.

Ecosystems are a complex web of interactions. These ecological networks are being reorganized by extinctions and colonization events caused by human impacts, such as climate change and habitat destruction. In a paper published this week in Nature Ecology & Evolution, researchers from McGill University and University of British Columbia have developed a new theory to understand how complex ecological networks will reorganize in the future.

Astronomers have pinpointed for the first time the home galaxy of a Fast Radio Burst, moving scientists a step closer to detecting what causes these powerful but fleeting pulses of radio waves. FRBs, which last just a few thousandths of a second, have puzzled astrophysicists since their discovery a decade ago.

Experiential Learning (EL) refers to the active process of learning by doing, in a mindful and intentional manner. According to the Association for Experiential Education, “Experiential Learning occurs when carefully chosen experiences are supported by reflection, critical analysis and syntheses.”

The innovative CaPS ExL Program was created by professional career counsellors and is designed to:

On  Saturday, November 26 from 3am to 5pm, Facilities will be performing renovation work that will affect temperatures in the Schulich Library of Physical Sciences, Life Sciences and Engineering. The steam distribution system in the Macdonald-Stewart Library Building (Schulich Library) will be shut down in order to fix six leaks before the winter season sets in. As a result, library users may experience colder than normal temperatures. Spaces will be open for study but users should dress accordingly.

We apologize for any inconvenience this may cause.

The transition from being sea creatures to living on land, even if it happened over 300 million years ago, seems to have left its traces on the way we keep our balance today.

“It’s a discovery that is likely to be controversial,” says Kathy Cullen, the senior researcher on a paper on the subject that was published recently in Nature Communications. She has been working on this problem for over a decade with her colleague Maurice Chacron who also teaches in McGill’s Department of Physiology.

Much of the influence on climate from air pollution in East Asia is driven by consumption in the developed countries of Western Europe and North America, according to research co-led by McGill University atmospheric scientist Yi Huang.

In a paper published online this week in Nature Geoscience, Huang and colleagues from China, the U.S. and U.K. report that international trade shifts the climate impacts of aerosols -- solid or liquid particles suspended in air -- from net consuming countries to net producing countries.

Rare minerals from Siberia found to have same structure as some man-made metal-organic frameworks

One of the hottest new materials is a class of porous solids known as metal-organic frameworks, or MOFs. These man-made materials were introduced in the 1990s, and researchers around the world are working on ways to use them as molecular sponges for applications such as hydrogen storage, carbon sequestration, or photovoltaics.

Minimum daily temperature -3 C increases need of search and rescues in Nunavut, affecting culturally valued hunting activities of Inuit

Search and rescue operations in Nunavut have more than doubled over the past decade. In the communities of the vast northern Canadian territory, it’s commonly felt that climate change is one factor making hunting riskier in the spring and fall.

...In 2011, the mechanochemist Tomislav Friscic and his team used mechanochemical methods to make bismuth subsalicylate, the active ingredient of Pepto-Bismol, by grinding together bismuth oxide and salicylic acid. The method not only does away with solvents, but also uses bismuth oxide, a safe reagent, in lieu of toxic bismuth salts.
