U of M partners with firm behind proposed sand mine to study Manitoba groundwater

Julia-Simone Rutgers 5 minute read Friday, Feb. 13, 2026

University of Manitoba researchers will soon have a new, non-invasive tool to study the province’s vast groundwater resources after inking a partnership with Alberta-based mining company Sio Silica.

“If the technology works … it’s going to provide a mechanism to do real-time monitoring of changes in groundwater,” Ricardo Mantilla, an associate professor in the university’s civil engineering department and lead researcher for the project, said in an interview.

The emerging technology — called absolute quantum gravimetry — can measure changes in gravity caused by changes in groundwater levels, allowing researchers to better understand the flow and storage of underground water resources without the need for “expensive and disruptive” drilling, he said.

“That obviously has applications for (Sio Silica), but it can have very important implications for how we understand groundwater in aquifers in our province.”

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.

Agricultural innovation takes hit in federal cuts

Laura Rance 4 minute read Saturday, Jan. 31, 2026

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.

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.

U of M chemist earns award for work on new drug candidate for treating Lou Gehrig’s disease

Conrad Sweatman 3 minute read Monday, Nov. 17, 2025

A University of Manitoba PhD candidate with a dramatic life story has been awarded the Mitacs Innovation Award for co-inventing an aspiring new drug candidate for treating amyotrophic lateral sclerosis (ALS), better known as Lou Gehrig’s disease, announced Monday.

“I thought, like, it’s a spam call. Then someone told me that, ‘You have been selected for the (award),’ so I was numb for 10 to 20 seconds,” says medicinal chemist Nitesh Sanghai, currently pursuing a doctorate at the U of M’s college of pharmacy under the supervision of Prof. Geoffrey K. Tranmer.

Sanghai doesn’t talk about “rags to riches” but instead “grass to grace” in describing his trajectory. The 43-year-old from Jharia, a small town in the Jharkhand district of India, says he was the first person in his family to pass India’s Grade 10 board examination, a gateway to further secondary and post-secondary education.

“I thought of breaking the cycle and pursuing studies with passion and privilege, which my family never had,” he says.

Elementary students share struggles with reading after report reveals education system failing

The Manitoba Human Rights Commission published the long-awaited results of a probe into how schools are teaching children to read — or failing to do so — at the end of October.

The 70-page report represents Phase 1 of a special project that’s become known as “Manitoba’s Right to Read.” A followup on the implementation of investigators’ recommendations is expected in 2026-27.

Local investigators concluded many teachers do not have training in structured literacy, a neuroscience-backed philosophy founded on explicit instruction in phonics, which stresses recognizing the connection between sounds and letters/letter combinations.

The structured-literacy method of teaching had all but lost the so-called “reading wars” by the 2000s, amid concerns memorizing letter-sound associations was repetitive and, as a result, was destroying students’ motivation to learn. Schools pivoted to prioritizing exposing children to a wide variety of interesting and increasingly difficult texts.

U of M research underscores importance of polar bears to future of Arctic

Katie May 5 minute read Tuesday, Oct. 28, 2025

Polar bears are generous hunters whose leftovers feed many other animals, new research shows, casting the protected species as a major provider, not just a vulnerable predator in a province that attracts thousands of polar bear watchers every fall.

Arctic foxes, wolverines, eagles, hawks, gulls and even younger bears are among at least 11 species who feast on the prey left behind by polar bears. The latest study calculates the leftovers: 7.6 million kilograms per year in picked-over seal carcasses left on sea ice.

That’s a conservative estimate, said biologist and University of Manitoba PhD candidate Holly Gamblin, lead author of the study published Tuesday in the journal Oikos from the Nordic Ecological Society.

“A bunch of my co-authors are in that polar bear research world and have been thinking about investigating (this issue), knowing that it’s this really under-represented and under-studied component of the story, when we think about polar bears as apex predators,” said Gamblin, who has studied Arctic foxes. “They had had this idea for a while and I was just sort of in the right place at the right time.”

A Winnipeg non-profit committed to advancing digital agriculture has inked a deal with the North American subsidiary of a global leader in phosphate-based fertilizers.

Leaders from Enterprise Machine Intelligence and Learning Initiative and OCP North America signed a collaboration agreement last week. They said the collaboration will focus on advancing agricultural innovation through field-based research that will take place through EMILI’s Innovation Farms powered by AgExpert.

Innovation Farms spans more than 14,000 acres across two Manitoba farms to provide demonstrations, testing and validation of agriculture technology and production practices in commercial farm settings.

The partnership will allow EMILI to give Manitoba farmers a first-hand look at new innovations, said Jacqueline Keena, managing director.

One day, I won’t need to keep up.

I look forward to that. When I won’t need to know what is happening with tariffs and governments, when I won’t have to fill my morning cup with a daily dose of man’s inhumanity to man, when I don’t have to dig through dross.

I’m just back at work after a few weeks out in a non-media world, realizing after several days I felt like I was coming up from underwater — and that, crucially, I was actually thinking about things beyond the regular churn of news. That I was having thoughts not directly connected to work purposes, that delightful meanderings of mind were still possibly in my weary head.

Thoughts about the domed shape of a sea urchin’s pale-green shell once all of its spines have fallen away; about the feel of small smooth beach rocks as you hold them in place against your index finger and rub them with you thumb. About the distance and weight of the horizon on a grey day, and the slap and lop of small waves on a beach protected by offshore rocks.

Ottawa earmarks $29M for energy retrofits for Manitoba households

Julia-Simone Rutgers 3 minute read Friday, Sep. 12, 2025

Manitoba homeowners and renters will be the first to benefit from a new federal program to reduce — and for some, eliminate — the cost of energy retrofits.

Federal environment and natural resources ministers Julie Dabrusin and Tim Hodgson joined provincial officials in Winnipeg’s Chalmers neighbourhood Friday to announce $29 million for Efficiency Manitoba under the greener homes affordability program.

“The way we heat, cool and power our homes impacts our environment, our wallets and the comfort of our daily lives,” Hodgson said, adding that 7,000 modest-income households in Manitoba would have access to no-cost energy retrofits.

“That will make their energy bills hundreds of dollars cheaper, their homes more comfortable and their carbon footprint smaller,” he said.

It is an incredible economic and political gift that could keep giving to Manitoba’s NDP government for years, if not decades, to come.

This week, Prime Minister Mark Carney released a list of five major projects that his government would fast-track to give Canada more economic independence from the United States. No Manitoba projects made that first short list, but something called “Churchill Plus” was identified as being under consideration for approval in the second round.

Churchill Plus includes improvements to the Port of Churchill in Manitoba’s North, including the provision of an icebreaker ship and possibly an all-weather road, to allow greater access to the port and provide improved transportation links for northern and Indigenous communities.

There is no way to exaggerate the economic and political dividends that could flow from Churchill Plus.

Some residents of Steinbach were mopping up and assessing damage Friday after the southeastern Manitoba city was swamped by two months’ worth of rain in about four hours.

An animal rescue charity was hit by catastrophe again when basements and streets flooded almost a year to the day a deluge inundated buildings.

“Last year, they told us it was a one-in-1oo-year event, and here we are 11 months later with the same event,” said Graham Pollock, vice-president of Steinbach and Area Animal Rescue.

He said the organization moved almost two dozen cats and kittens to foster homes after nearly 2.1 metres (seven feet) of floodwater filled the shelter’s basement overnight Thursday.

As the province tries to move away from its reliance on private agency nurses, data show the practice continues to increase in Manitoba.

A report Thursday from the College of Registered Nurses of Manitoba shows there were 1,611 nurses working for private agencies in 2024, up from 1,418 in 2023.

“Our fundamental mandate as the professional regulator is to ensure public protection and provide the conditions that work towards supporting and ensuring patient safety,” said college spokesman Martin Lussier.

“When there is a significant shift in the practice of (nurses) that we regulate, part of our work is to assess: does that create new challenges or risks.”

Churchill and LNG would mix like oil and water

Chris Debicki 5 minute read Tuesday, Sep. 9, 2025

Churchill has always been a place of connection and of change. However, last week’s remarks from Prime Minister Mark Carney that Churchill could become a year-round export terminal for liquefied natural gas (LNG) suggest a risky vision for the future that could imperil the balance and diversity that has allowed this unusual community on Hudson Bay to endure.

At its founding, Churchill connected Inuit, Dene and Cree communities with the Hudson Bay Company’s vast trading network. In the waning days of the fur trade, Churchill re-emerged as an important cold war base, housing thousands of troops.

When North America’s defence needs changed, Churchill again reinvented itself as a research hub for aerospace and a broad array of scientific enquiry. Through the second half of the 20th century, Churchill also became a critical social service centre for much of Hudson Bay and the central Arctic. Now it has emerged as one of Canada’s great ecotourism destinations. Few places better capture the adaptability and resilience of the North.

The prime minister and Premier Wab Kinew have both described Churchill LNG exports as a “nation-building” project. Investment in the transportation corridor that connects the Arctic to southern Canada through the port and railroad is indeed overdue. The Port of Churchill is a national asset with enormous potential and diverse strengths.

There’s more to a burl than meets the eye. On the surface the flawed wood is a gnarly, lumpy mess. But beneath the scars hides something rather special.

“Burls are an unappealing wart-like growth on a tree,” artist Gary Foidart, 69, explains.

“They are horrific looking on the outside. Some of them look terrible. You never know what you are going to hit when you cut a burl open but the wood inside is the most beautiful wood there is. Each one is totally unique.”

Bulbous and rough, a wood burl forms when a tree experiences stress or disruption to its growth. Burls can also develop from insect infestation, bacterial or fungi growth, and environmental injuries.
