Are environmental toxins reducing men’s fertility?
Exposure to DDT can trigger changes to the heritable sperm epigenome and may raise risk of birth defects and disease, finds McGill-led study In a study that signals potential reproductive and health complications in humans, now and for future generations, researchers from McGill University, the University of Pretoria, Université Laval, Aarhus University, and the University of Copenhagen, have concluded that fathers exposed to environmental toxins, notably DDT, may produce sperm with health consequences for their children.

Medicinal drugs pollute the St. Lawrence River
Medicinal drugs pollute the St. Lawrence River
The 3,000-km artery contains a large quantity and variety of pharmaceutical compounds, some of which could be harmful to ecosystems and human health. A new study shows troubling levels of pharmaceutical pollution in the St. Lawrence River and its largest tributaries, especially near and downstream of urban areas.

More reporting needed to show progress on Ontario municipal climate and sustainability plans
More reporting needed to show progress on Ontario municipal climate and sustainability plans
University of Waterloo researchers will help Canadian municipalities monitor, measure and achieve climate mitigation goals While sustainability reporting is a widespread practice in the private sector, new research shows that the same cannot be said for Ontario municipalities. Researchers at the University of Waterloo studied 38 municipalities in Ontario, representing more than two-thirds of the population, and discovered that almost all municipalities publish their sustainability and climate change goals, but under half are formally reporting on their progress.

Researchers advocate for sustainable logging to safeguard against global flood risks
Researchers advocate for sustainable logging to safeguard against global flood risks
It's time to recognize the power of healthy forests in managing global growing flood risk, and to shift towards more sustainable forestry practices and policy. This call is emphasized by UBC researchers in a peer-reviewed article published recently in the journal Science of the Total Environment . Dr. Younes Alila , a hydrologist and professor in the faculty of forestry, and his graduate student Henry Pham synthesized decades of hydrology studies and found that many "severely and consistently underestimated" the impact of forest cover on flood risk.

Bioretention plants not impaired by road salt
Bioretention plants not impaired by road salt
The salt used to de-ice our roads does not reduce the effectiveness of the plants used in bioretention areas, according to a new study by Henry Beral, a Ph.D. candidate at UdeM. Increasing numbers of municipalities across Quebec are building bioretention areas to manage storm runoff. These areas serve two important functions.

Air quality alerts on track to quadruple by 2100
Air quality alerts on track to quadruple by 2100
Air pollution expected to worsen with climate change, exacerbating disparities as only some can adapt Air pollution is the main environmental cause of early death, and new research from experts in Canada and the United States finds that, in about 75 years, climate change will see the number of air quality alerts in the U.S. to quadruple.

Researchers’ tool to be part of European Space Agency’s Climate Change Initiative
New machine learning model predicts lake ice conditions with 94 per cent accuracy To advance climate change monitoring and public safety, researchers at the University of Waterloo have developed new tools that bring an unprecedented level of accuracy to identifying lake ice conditions. The researchers are the first to use machine learning models for processing satellite radar altimetry data that can identify between open water, thin ice, growing ice, or melting ice with 94 per cent accuracy.

New dimension of the genome discovered
Distantly related organisms that live in extreme temperatures and pH conditions develop similar DNA It has long been thought that an organism's DNA provides clues only about its ancestry and how the various forms of life on Earth are related - the more similar their DNA, the more closely the species are related.

Wolves of Northern Quebec: from sedentary to migratory
Wolves of Northern Quebec: from sedentary to migratory
The Northern Québec caribou is the longest migrating land mammal in North America. The wolf is literally right behind it. If Santa's reindeer share the misfortune of migrating caribou in northern Quebec, there's a good chance they'll have a pack of wolves on their heels during their December 25 jaunt.

Toxic chemicals found in oil spills and wildfire smoke detected in killer whales
Toxic chemicals found in oil spills and wildfire smoke detected in killer whales
Toxic chemicals produced from oil emissions and wildfire smoke have been found in muscle and liver samples from Southern Resident killer whales and Bigg's killer whales. A study published today in Scientific Reports is the first to find polycyclic aromatic hydrocarbons (PAHs) in orcas off the coast of B.C., as well as in utero transfer of the chemicals from mother to fetus.

Finding more sustainable ways to use plastics in agriculture
International scientists including UdeM professor Kevin Wilkinson address the worrisome problem of millions of tonnes of plastic being used on farms around the world. Every year, according to the United Nations Food and Agriculture Organization, some 12.5 million tonnes of plastic are used in agricultural production worldwide.

What’s for dinner? Paleontologist finds out through remarkable specimen
1st-ever prey found inside fossilized juvenile tyrannosaur leads to deeper understanding about feeding habits of these iconic predators The difference between a juvenile and adult tyrannosaur is massive - both figuratively and literally. While adults weighed around 3,000 kilograms, the weight of a pick-up truck, juveniles were much leaner.

Transforming CO2 into valuable products
Waterloo research team partners with BMO to turn pollution into renewable energy  By Nicola Kelly Faculty of Engineering An interdisciplinary research team from the University of Waterloo aims to tackle CO2 emissions in the value chain by transforming CO2 into valuable chemicals needed by industry. Supported by BMO, the research focuses on the use of green hydrogen to capture CO2 from power plants as well as the iron, steel, and cement industries, and convert it into useful gases via reverse water gas shift reaction.

Researchers sound out Canadian military's plan to combat ocean noise pollution
Researchers sound out Canadian military’s plan to combat ocean noise pollution
A new study from Simon Fraser researchers examines the Canadian military's efforts to reduce the impacts of underwater noise pollution on species during training exercises in the Pacific Ocean but caveat that more can still be done. The paper, published today in Marine Policy , takes aim at a report commissioned by the Canadian Department of National Defence (DND) to reduce the effects of noise pollution from military small-arms munitions training within "Whiskey Hotel", a 330-square-kilometre area in the Strait of Juan de Fuca off the British Columbia coast.

When polar bears hunt like sharks in the movies
When polar bears hunt like sharks in the movies
Researchers describe a novel technique used by polar bears to hunt snow geese Bylot Island, Nunavut, August 8, 2021, 1 p.m. A polar bear approaches a pond where some thirty moulting snow geese - unable to fly - have taken refuge. The bear enters the water, swims stealthily along the surface towards a goose and, once within 30 meters of it, disappears beneath the surface of the wave, then suddenly emerges..
