What to know about EPA decision to revoke a scientific finding that helped fight climate change

The Environmental Protection Agency on Thursday revoked its own 2009 “endangerment finding,” a scientific conclusion that for 16 years has been the central basis for regulating planet-warming emissions from power plants, vehicles and other sources.

The finding itself is straightforward: Carbon dioxide and other greenhouse gases — caused by burning fossil fuels such as coal, oil and gas — endanger public health and welfare.

It was adopted after the U.S. Supreme Court ruled in 2007 that greenhouse gases are air pollutants that can be regulated under the Clean Air Act.

The Trump administration says the finding hurts industry and the economy and that the Obama and Biden administrations twisted science to determine that greenhouse gases are a public health risk.

Get vaccinated for flu, COVID-19, measles to protect crowded hospitals: top doc

The province’s top doctor is asking Manitobans to get vaccinated as respiratory virus season threatens to strain hospitals and measles outbreaks tear though parts of Manitoba.

City sewage plant megaproject progresses amid need for more funding

The finishing touches are being put on four massive fibreglass sewage pipes inside a two-and-a-half metre thick concrete tunnel 20 metres underground.

When the work is done, they’ll start pumping out millions of litres of raw sewage per day.

The building that houses them may look modest, but it was made with as much concrete as half of the Canada Life Centre, with still some to go.

“We’ve got at least double that in the balance of the facility in other areas,” said Rob Black, the project director for the upgrade of the North End sewage treatment plant on Main Street North.

Babies given peanuts, fish, eggs early less likely to become allergic, study affirms

TORONTO - A new Canadian study says giving babies peanuts, eggs, fish and other common food allergens early and consistently decreases the risk they'll be allergic to them.

Senior author Dr. Derek Chu says researchers analyzed more than 190 food allergy studies from around the world to identify the strongest risk factors in developing food allergies.

Their findings, published Monday in JAMA Pediatrics, found that delaying the introduction of peanut-containing foods until babies were over 12 months old doubled their likelihood of becoming allergic to the nut.

The study showed similar results for fish and eggs.

Clear Lake group withdraws review against Parks Canada

Fairness for Clear Lake has decided to withdraw its judicial review against Parks Canada following a court delay that pushed the 2025 boat ban hearing to May.

As men’s health enters the national conversation, advocates call for co-operation

OTTAWA - The upcoming launch of a national strategy on men's and boys' health is a positive sign that men's well-being is becoming part of the mainstream conversation in Canada, advocates say — even as they warn that it should not become partisan political fodder.

The Movember Institute of Men's Health and researchers from the University of British Columbia called on the government to launch such a strategy in a report released last summer.

Health Minister Marjorie Michel said she plans to launch a national strategy on men's and boys' health in 2026 by working with colleagues in multiple departments, including Veterans Affairs, Women and Gender Equality and Indigenous Services.

Catherine Corriveau, Movember's director of policy and advocacy, said the government has taken an important first step by acknowledging the problem.

Bracing for a future global water shortage

Declaring bankruptcy is by all accounts a painful, traumatic and perhaps even humiliating process.

Manitoba has most measles cases in Canada — and it’s likely much worse, doctors say

Manitoba has the country’s highest number of reported measles infections in 2026 — a year after the province’s outbreak began — while a surge brings stronger messaging from the government.

Dr. Davinder Singh, who is Manitoba’s public health lead on measles, said the province is seeing its highest monthly totals since May.

“Unfortunately, we’re seeing an increase in the number of detected or reported cases. We also know the number of cases that are diagnosed are only a relatively small fraction of the true number of cases out in the community,” he said Wednesday.

“We can estimate that there may be about 10 times as many infections as we have that get reported to us or that get detected.”

Agricultural innovation takes hit in federal cuts

Everyone knew cuts to federal programs and jobs were coming.

Something must give if elected officials are to make good on promises to address what many characterized as Canada’s bloated bureaucracy and ballooning deficits, while boosting its military defence systems and protecting the economy from a neighbour gone rogue.

And while the Canadian effort to shrink the cost of governing is a little less dramatic than that in the U.S. a year ago, the application of across-the-board cuts has been anything but surgical.

Farmers and unions, who rarely agree on anything, are united in opposition to news Agriculture and Agri-Food Canada is closing three research facilities and four research farms, and cutting around 650 positions. The cuts include a host of programs, including those focused on organic farming, regenerative agriculture and climate adaptation.

Some blind fans to experience Super Bowl with tactile device that tracks ball

Some blind and low-vision fans will have unprecedented access to the Super Bowl thanks to a tactile device that tracks the ball, vibrates on key plays and provides real-time audio.

The NFL teamed up with OneCourt and Ticketmaster to pilot the game-enhancing experience 15 times during the regular-season during games hosted by the Seattle Seahawks, Jacksonville Jaguars, San Francisco 49ers, Atlanta Falcons and Minnesota Vikings.

About 10 blind and low-vision fans will have an opportunity to use the same technology at the Super Bowl in Santa Clara, California, where Seattle will play the New England Patriots on Feb. 8. With hands on the device, they will feel the location of the ball and hear what's happening throughout the game.

Scott Thornhill can't wait.

Agriculture and Agri-Food Canada announces closure of research operations, job cuts

Agriculture and Agri-Food Canada says it is closing seven of its research operations as part of the federal government's efforts to cut the size of the public service.

The federal department said research centres in Guelph, Ont., Quebec City and Lacombe, Alta., as well as four satellite research farms across Nova Scotia, Saskatchewan and Manitoba are closing.

It said so far, approximately 665 department positions have also been reduced and nearly 1,050 employees received notices on Thursday.

"There are no imminent site closures, and any wind-down of scientific operations would follow a careful decision process that could take up to 12 months," the department said in a statement Friday.

First Nation says Hydro misuse of river diversion destroying sturgeon population

A northern First Nation is calling on Manitoba Hydro to alter its use of the Churchill River diversion to protect a lake sturgeon population allegedly decimated by hydroelectric operations.

Tataskweyak Cree Nation Chief Doreen Spence said the culturally significant species is facing extinction on the river system without immediate intervention, 50 years after Manitoba built the diversion to send water to large power generating stations.

“The diversion has artificially altered the flow of the water… so much that the river is barely able to sustain life as it once did,” Spence told reporters in Winnipeg Thursday.

“Manitoba Hydro must operate the diversion in sync with the natural flow regime of the river for the sturgeon to survive.”

Funding shortfall undermines Canada’s ability to track diseases threatening wildlife, human health

The head of a national network that tracks the spread of wildlife diseases says a persistent funding shortfall is undermining Canada’s ability to detect and respond to emerging threats to biodiversity, agriculture and human health.

Damien Joly is the chief executive officer of the Canadian Wildlife Health Cooperative, a network of Canada’s five veterinary schools and the B.C. government’s Animal Health Centre. The CWHC works with federal, provincial and territorial governments to monitor wildlife diseases across the country.

In an interview with The Narwhal, Joly said the organization is “cash strapped across the board.”

“We do not have the resources we need to effectively monitor these diseases,” he said.

Manitoba enterprise at forefront in bolstering soil structure

Soil health has always been important to anyone who wants to grow plants that flourish but never more so than today. Soil degradation due to drought and extreme weather is a global problem that has a direct link to agricultural productivity and food security.

The status of soil health in Canada is not a concern limited to farmers and backyard gardeners. Scientists, policy makers and researchers are recommending urgent action to protect soils to safeguard the future of our food production.

In June 2024, following an 18-month study of soil conditions in Canada, the Standing Senate Committee on Agriculture and Forestry released the report Critical Ground: Why Soil is Essential to Canada’s Economic, Environmental, Human and Social Health. The report, which is based on testimony from more than 150 experts, concluded that soil in our country is at risk, with implications for food production, climate resilience and biodiversity.

Dale Overton takes soil health and its implications for fertility and food production seriously. His company, Overton Environmental Enterprises, manufactures several microbial products for large-scale agriculture as well as for the home gardener. Overton is deeply interested in regenerative farming practices and how biological amendments can benefit soil health, carbon sequestration and soil microbiomes, and boost growth rates and crop yields.

Body’s cellular makeup leads to big, existential questions

French science journalist and author Lise Barnéoud’s first book Hidden Guests is a fascinating, well-researched, atmospheric book on micro-chimerism — the presence of genetically distinct cells from one person circulating in another person.

Talking cows? N.S. researchers think they are getting closer to understanding moos

HALIFAX - If a cow moos in a barn and no one is around to hear it, could you still understand what it’s trying to say?

Researchers at Dalhousie University are hoping to answer that question.

Led by Dr. Ghader Manafiazar, the team at Dalhousie’s agricultural campus in Truro, N.S., has been recording and analyzing cow noises to see whether the animals have different vocal patterns.

Humans can utter words using various inflections and meanings, said Manafiazar, a professor in the faculty of agriculture. His research is trying to determine whether the same holds true for animals. “When they say ‘moo,’ is it different from saying ‘moooooo’?”

Animal Nation includes rural and Indigenous people in its portraits of Prairie and northern animals

At first glance, Winnipeg-born producer Jesse Bochner’s seven-part series Animal Nation brings to mind docu-series such as Wild America, Planet Earth and Nature.

Skating trail expected to open in time for New Year’s Day activities at The Forks

Skaters, rejoice: the Nestaweya River Trail at The Forks could be open as early as New Year’s Day, marking one of its earlier openings in recent years.

The port rink on the Assiniboine River and a small section of the the iconic river trail opened on Dec. 31 last year. The earliest recorded opening of the six-kilometre skating trail was Dec. 21, 2013.

“We had a good freeze this year… and we’re hoping for a nice, long season this year,” Adam Dooley, spokesperson for The Forks, said Monday.

Sections of the trail, which snakes along the Red and Assiniboine rivers and meets at The Forks port, have some slush owing to recent snowfall and may take more time to open, Dooley said.

Goats set for farm’s traditional Christmas tree feast

It’s a holiday feast fit for a goat.

Fir, spruce and pine trees are as delicious as turkey and trimmings to about 20 goats at a farm just south of Winnipeg.

Aurora Farms will once again welcome donations of trees once the presents have been opened, the lights turned off, and the ornaments removed.

“Goats are naturally browsers rather than grazers; in the wild, they’ll prefer bushes and shrubs, kind of heartier foraging, over pastureland,” said Aynsleigh Kerchak, general manager at Aurora. “For them, they like a chance to deal with the leaves and needles on the trees.”

U of M researchers studying whether genetic testing helps zero in on effective mental-health treatment meds

A team of University of Manitoba researchers is recruiting people seeking mental-health treatment for a study that could take the guesswork out of medication with the help of genetic testing.

The study will offer free pharmacogenomic testing — which predicts how a person may react to medications based on their genetic makeup — to 200 adults who are looking to start a new medication or switch their medication treating a mental-health issue.

“Someone with mental-health conditions, they (try) multiple medications, and sometimes it takes months or years to get to a point where those drugs work for them, or to have less side effects,” said Dr. Abdullah Maruf, the lead investigator on the study and assistant professor in U of M’s College of Pharmacy.

“Pharmacogenomic testing can find out how our body will respond to these kinds of medication.”

How does climate change affect the likelihood of extreme rain? Federal department aims to publish rapid results

Federal scientists will start to publish rapid results looking at how much more likely major rainstorms have become due to climate change.

Environment and Climate Change Canada says it's expanding its rapid attribution system, so far used to analyze extreme temperatures, to also include extreme precipitation.

"This area of research supports important decision-making that helps Canadian communities prepare for and adapt for the changing frequency and severity of extreme weather events," said Madalina Surcel, a climate extreme specialist with the department.

Officials say they have already run the tool on 42 extreme precipitation events across Canada since June. They say the vast majority of those events were up to two times more likely to happen because of climate change, and three were up to 10 times more likely.

Killer whales and dolphins may be helping each other hunt of B.C. coast: new report

HALIFAX - Scientists have found evidence that two unlikely collaborators — killer whales and dolphins — may be helping each other find and feast on salmon off the coast of British Columbia.

Sarah Fortune, an assistant professor in oceanography at Halifax’s Dalhousie University said it would appear the massive fish-eating whales may be working with Pacific white-sided dolphins, which have been spotted eating the salmon chunks the killer whales produce.

She is a co-author of a paper published Thursday in Scientific Reports that found the two species appear to be working together while they forage.

Recordings picked up "this audible crunch as the whale bites down, then you see these fragments of fish that are released,” and then dolphins swim in to eat the pieces, Fortune said.
