Bear rescue takes RM to court over quarries

Nicole Buffie 3 minute read Wednesday, May. 27, 2026

Manitoba’s only black bear rescue is asking the court to quash a pair of quarry approvals in the Rural Municipality of Rockwood, saying the operations will have devastating effects on its operation.

Manitoba Bear Rehabilitation Centre Inc. and its owners have asked the Court of King’s Bench to declare the RM approvals invalid. It also seeks an injunction to prevent extraction at the site, pending the court’s decision.

The application claims the limestone quarry approvals were unlawful and the municipality failed to conduct a fair, transparent, and procedurally adequate decision-making process.

In March, the RM held a public hearing for two quarry applications by Amrize Canada. Hundreds of letters opposing the operations were submitted to the RM and dozens of people attended the meeting to voice their concerns, Black Bear Rescue Manitoba co-owner Judy Stearns said at the time.

Calls for more teacher training, consultation and updating Manitoba’s overhauled science curriculum are growing ahead of a mandatory rollout planned for the fall.

The Education Department is in the process of adjusting what scientific concepts students must learn and experiment with between kindergarten and Grade 10.

The new curriculum calls on teachers to regularly integrate Indigenous perspectives into their lessons and focus on building scientific literacy while leaving a lot up to professional discretion.

A pair of local researchers who’ve been surveying pilot participants have found “mixed responses.”

By winter, a pair of Winnipeg entrepreneurs aim to have portable vision and concussion-screening products circulating Canada.

“Designing a device that is portable, affordable and AI-based and smartphone-based is a puzzle,” Dr. Behzad Mansouri said, a prototype of the device on the desk in front of him at the Brain, Vision and Concussion Clinic off St. Anne’s Road on Monday.

He’s a neuro-ophthalmologist at the clinic. He’s also the co-founder of Neuroptek, the medical technology company behind headsets meant to help diagnose concussions and other vision and neurological injuries and disorders.

The products look like virtual reality headsets. Instead of games, users take visual tests they’d find at a doctor’s office. They might try to read letters or identify colours.

Proponents of solar power push for provincial infrastructure investment to boost grid resilience

Julia-Simone Rutgers 15 minute read Saturday, May. 23, 2026

In the early 1970s, licence plates were stamped with the slogan “Sunny Manitoba” — a nod to long summer days, crisp blue winter skies and frequent sun dogs reflecting off of blinding white snow. While the slogan later changed, Manitoba’s ranking as Canada’s second-sunniest province has not.

Despite that sunlit reputation, solar power — one of the most-developed renewable energy sources — makes up just a small fraction of the province’s electricity grid.

“It’s extremely marginal, especially when you compare to other jurisdictions like Alberta and Saskatchewan,” said James Wilt, policy development manager at Climate Action Team Manitoba.

Manitoba boasts a predominantly emissions-free grid, with 97 per cent of its power generated by a network of hydroelectric dams. But the provincial utility, Manitoba Hydro, has forecasted that its once-abundant renewable energy source will soon fall short. There is growing demand for power amid the electrification of sectors like transportation and heating, and the rapidly growing interest in developing electricity-hungry data centres. Combined with more unpredictable water levels owing to climate factors like extreme drought, it’s all prompted the utility to warn that capacity could run out as soon as 2030.

‘What you don’t know can’t hurt you.”

It’s an interesting maxim, accurate in some settings.

But equally accurate might be, “What you won’t know, can hurt you.”

The last few years of politics — particularly in the United States but in other places as well — have been remarkably fractious and absolutist. You’re on one side or the other. You choose who to listen to, and what to believe in. People you don’t agree with are obviously stupid.

Adverse weather slows pace of seeding to below 5-year average

Gabrielle Piché 3 minute read Thursday, May. 21, 2026

High winds and a cool spring have caused a lag in Manitoba’s crop-planting season.

At this time last year, more than half of crops — at least 57 per cent — had been seeded, according to reports. By Tuesday, just 37 per cent of 2026 seeding was complete.

The pace falls behind the five-year average: 43 per cent of seeding is usually done by May 19.

A crop report from the Manitoba government points to “extremely high winds” and rainfall slowing progress.

As permafrost thaws, some headwaters in Canada’s North turn orange and toxic: study

Jordan Omstead, The Canadian Press 7 minute read Friday, May. 22, 2026

Ancient bedrock exposed by disappearing permafrost is releasing toxic metals into Canada's northern rivers, a new study says, with once-pristine subarctic streams now comparable in some cases to highly acidic, contaminated mining sites.

The findings out of Yukon point to an "unfolding environmental disaster," one co-author said, and adds to alarm over the rapid climate-fuelled changes in the North.

"We don't know the end point, but there's nothing about this that gives me any feeling of like, 'oh, we're going to be OK'," said co-author Sean Carey, a professor at McMaster University.

"I'm not even a gloomy person. This looks pretty gloomy."

Generic semaglutide to hit Canadian pharmacies this week at a fraction of the cost of Ozempic

Nicole Ireland, The Canadian Press 5 minute read Thursday, May. 21, 2026

TORONTO - Two generic versions of Ozempic are set to start arriving in Canadian pharmacies this week, which means patients who use the drug to treat diabetes or for weight loss may have more options for a fraction of the cost.

Health Canada approved both Dr. Reddy's and Apotex's generic semaglutide — the active ingredient in brand-name Ozempic — about three weeks ago.

Apotex is based in Canada and said it began shipping its product on Tuesday.

India-based Dr. Reddy's said in an email that its semaglutide has already arrived in "select" Canadian pharmacies and will be available more widely across the country in the coming days.

I know things aren’t going well when cracks keep forming on my clay — but not to worry. I’d been paying attention when instructors Jillian Sheedy and Joanne Roberts told me how to deal with this problem.

So I confidently dip my brush into the water and start moistening my clay to smooth it out. Except I’ve added a bit more water than I should have, and now the clay is wet and extremely sticky.

Beside me, Roberts smiles reassuringly.

“It’s a task that requires a little bit of patience,” she says, carefully removing the brush from my hand.

Pair of bird books offer fascinating insight into the avian world

Reviewed by Gene Walz 6 minute read Saturday, May. 16, 2026

These two newly-released bird books couldn’t be more different. Jackie Morris and Robert Macfarlane’s The Book of Birds is artful and poetic; Louis Lefebvre’s A Bird’s IQ is analytical and academic. Each would make an attractive addition to the libraries of people interested in birds — but not without certain provisos.

The subtitle of The Book of Birds is deceptive — it’s not really a “Field Guide” in the usual sense, too substantial and beautiful to carry along on a bird outing. In hardback with a blue cloth spine and a blue-ribbon page-holder, it’s more like a church song missal than toteable identification helper. It’s best kept inside, protected from wind and weather and damp fingerprints.

The Book of Birds is a follow-up to Morris and Macfarlane’s previous collaboration The Lost Words. When the Oxford Junior Dictionary dropped a bunch of words connected to the natural world (such as acorn, otter, fern, newt and wren), the renowned artist and celebrated author created a “spell book” to conjure back 20 of those words and bring increased awareness of the things the words describe. It proved to be immensely popular.

Here they focus on 49 birds, presented alphabetically from avocet to kestrel to sparrow to yellowhammer, that are in danger of disappearing completely from the natural (European) world. Morris provides the spectacular bird illustrations, and Macfarlane waxes poetic on each of them in the hopes readers will not just identify birds, but “identify with them.”

The dangers of gambling on nuclear power

Anne Lindsey 5 minute read Friday, May. 15, 2026

Dismissing climate science, setting Canada apart from most nations and planting us firmly in the United States’ camp, the Carney government is betting the farm on a “nuclear renaissance.”

There have been numerous indications this was coming. But Energy Minister Tim Hodgson’s April 29 statement to the Canadian Nuclear Association, following immediately on the launch of the “Canada Strong Fund” left no doubt that our investment banker prime minister is determined to pursue his nuclear energy superpower dreams.

As the UN Climate Envoy, Mark Carney famously said there is “no path to net zero without nuclear.” This has been a mantra of successive Liberal governments even as Canada’s last nuclear build was in the 1980s, and nuclear’s share of global electricity production has been steadily declining. It’s also been the rallying cry of nuclear advocates spending big to persuade anxious populations experiencing floods, droughts and wildfires that nuclear power will solve our climate disaster in the making. That claim is false.

Eight years ago, the Liberals rolled out their “SMR roadmap,” predicting the first (slightly) smaller new reactors would be operational in 2026. It isn’t happening. A new report by M.V. Ramana and Susan O’Donnell — Assessing Small Modular Nuclear Reactors in Canada — details the $4.5 billion spent by Canadian governments on SMRs with zero kilowatts of electricity generated to date. Most of that money went to the potential first SMR in Canada, the BWRX 300, an American design by GE Hitachi that uses enriched uranium fuel, not available in Canada.

Astronomers believe they’ve detected an atmosphere around a tiny, icy world beyond Pluto

Marcia Dunn, The Associated Press 3 minute read Saturday, May. 16, 2026

CAPE CANAVERAL, Fla. (AP) — A new study suggests that a tiny, icy world beyond Pluto harbors a thin, delicate atmosphere that may have been created by volcanic eruptions or a comet strike.

Just 300 miles (500 kilometers) or so across, this mini Pluto is thought to be the solar system's smallest object yet with a clearly detected global atmosphere bound by gravity, said lead researcher Ko Arimatsu of the National Astronomical Observatory of Japan.

“This is an amazing development, but it sorely needs independent verification. The implications are profound if verified,” said Southwest Research Institute's Alan Stern, the lead scientist behind NASA's New Horizons mission to Pluto and beyond. He was not involved in the study.

The finding offers fresh insight into our solar system’s farthest, coldest objects in a region known as the Kuiper Belt. Researchers used three telescopes in Japan to observe the object in 2024 as it passed in front of a background star, briefly dimming the starlight.

Seeding clock ticks loudly on Prairie fields

Laura Rance-Unger 4 minute read Saturday, May. 2, 2026

If the forecast holds, Manitoba fields will be crawling with equipment this week, as the race to seed this year’s crop begins.

An early-May start to seeding is right on track by historical standards, but still feels late this year, partly because it’s been so cold. Seeding dates have been edging earlier over time, especially for crops such as wheat, as farmers discover they can get away with super-early seeding under the right circumstances.

Due to the compressed growing season characteristic to this part of the world, it’s well-documented the later the crop is seeded, the lower it yields. However, seed too early and there’s a risk that a late-spring frost will force farmers to reseed some fields.

For most, it’s a gamble worth taking.

Colin Rémillard is obsessed with the weather.

When he and his family opened Winnipeg gardener’s staple Jardins St-Léon Gardens for the 2026 season on Wednesday, it came after weeks of chilly weather. But with staff itching to go — and customers waiting — they decided to open the doors after a “mad dash” to bring in produce and tag every product in the store one day earlier.

“Everything seemed to roll fairly well. We’re in good shape. It’s going to be a colder spring, that’s just reality,” Rémillard said from the garden centre Friday.

“We’ve had really nice springs for the past one or two years. We always remember only one year in the past, so we think this is unusual, but it is pretty normal to have this amount of cold.”

Syrup season in swing

Louise May has been tapping the trees at the St. Norbert Arts Centre for 37 years, extracting the nectar that becomes maple syrup.

May began making syrup as a way to connect with the trees and continue in the footsteps of the Trappist monks who originally planted the maple trees more than a century ago.

Recently, the endeavour has taken a more spiritual turn as May began collaborating with kookum Christine Cyr and sharing the syrup for a strawberry heart medicine used during Sundance ceremonies, which include a four-day fast.

“This is a really powerful medicine,” says Cyr. “It physically and spiritually helps people to get through” the ceremony when it is typically taken on the third day of the fast. At the beginning of the season, community members drummed, sang, and offered tobacco to each tree as May put the taps in.

“This announcement is an absolutely historic moment in time where we have all different levels of government (and) … the nations coming together to preserve some of the most beautiful areas in the world,” Manitoba Environment Minister Mike Moyes said Friday.

“I am so proud to be part of a government that is moving forward on this historic agreement that is going to protect seven per cent of Manitoba.”

HOUSTON - When Canadian astronaut Jeremy Hansen first floated to the window after the Orion capsule's bone-rattling launch into space early this month, what he saw and felt left him grasping for words.

He saw the sweep of the ocean first, and then, drifting into view, the rich, dusty red of Australia. And behind it all was the vastness of space, with the edge of Earth's atmosphere shining like a bubble of blue glass in the black.

"It was pretty extraordinary," Hansen told The Canadian Press at NASA's Johnson Space Center in Houston Thursday.

The enormity of what Hansen and his Artemis II crewmates experienced is still settling in a week after they returned to Earth, splashing into the Pacific Ocean following a 10-day lunar fly-around.
