While you might have stopped and thought about the poetry of the trees that are a constant in the city of Winnipeg — big and small, sometimes healthy and other times failing, you probably haven’t thought about the value of a tree.

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.

Carney delays electric vehicle sales mandate by one year, launches review

Nick Murray, The Canadian Press 7 minute read Monday, Sep. 22, 2025

OTTAWA - The federal electric vehicle sales mandate will not be implemented in 2026 as planned, Prime Minister Mark Carney said Friday, pushing back by at least a year a policy that would have set minimum sales targets for electric and plug-in hybrid vehicles.

Introduced by the Liberals under former prime minister Justin Trudeau, the mandate would have required 20 per cent of all new vehicles sold in Canada next year to be electric.

The standard as written is to rise steadily each year until 2035, by which point all new light-duty vehicles sold in Canada were to be fully electric or plug-in hybrids.

But at a press conference in Mississauga, Ont., Carney said he is suspending the mandate for 2026 and launching a 60-day review of the program to help find "future flexibilities and ways to reduce costs."

American Eagle counts new customers after Sydney Sweeney ad frenzy and shares soar

Michelle Chapman, The Associated Press 4 minute read Monday, Sep. 22, 2025

Shares of American Eagle Outfitters spiked 34% Thursday after the teen clothing retailer said the frenzy surrounding its Sydney Sweeney ad campaign drew new customers during its most recent quarter.

American Eagle rolled out its new new ad campaign starring 27-year-old actor over the summer. The fall denim campaign sparked a debate about race, Western beauty standards, and the backlash to “woke” American politics and culture.

Negative reactions centered on ads that used the word “genes” instead of “jeans” featuring the blonde-haired, blue-eyed actor known for the HBO series “Euphoria” and “White Lotus.”

But American Eagle did get noticed, executives said late Wednesday in a call after the Pittsburgh retailer posted second quarter earnings.

Eight doctors from around the world have signed on to work in clinics across the Prairie Mountain Health region through a provincial program.

Six doctors have set up practice in Swan River, Neepawa, Roblin and Virden, while two physicians are scheduled to begin in Souris and Swan River in mid-September. All were recruited by the Medical Licensure Program for International Medical Graduates, which helps physicians gain Canadian citizenship or permanent residency in exchange for working in communities in desperate need of doctors.

The physicians are from Nigeria, Pakistan, Iran, the Philippines and Bangladesh. In exchange for assisting foreign-trained doctors to become fully licensed to practise in Manitoba, they’ve agreed to practise in those communities for at least four years.

While the program has been used since 2001 to recruit doctors to the underserved Westman area , the local health authority has ramped up efforts in the past two years to improve the chance that internationally trained doctors establish roots in rural Manitoba. The hope is that they’ll stay more than four years.

Russian hackers are likely behind suspected sabotage at a dam in Norway in April that affected water flows, police officials told Norwegian media on Wednesday.

The director of the Norwegian Police Security Service, Beate Gangås, said cyberattacks are increasingly being carried out against Western nations to stoke fear and unrest.

The Associated Press has plotted more than 70 incidents on a map tracking a campaign of disruption across Europe blamed on Russia, which Western officials have described as “reckless.” Since Moscow's invasion of Ukraine, Western officials have accused Russia and its proxies of staging dozens of attacks and other incidents, ranging from vandalism to arson and attempted assassination.

Intelligence officials told the AP that the campaign is becoming more violent.

Among the many technical terms from fields such as neuroscience, artificial intelligence, applied mathematics and genetics found in this fascinating new book by bestselling Canadian science writer/distance runner/physicist Alex Hutchinson, the reader discovers “prediction error.”

It’s a term that comes from studies of how the brain makes sense of the impressions presented to it by the senses. The brain doesn’t simply receive sensory data; rather, it continually makes predictions based on partial sense data and feeds these back to the senses. When we get lost, the predictions we make tend to be errors.

We also carry a variant of the gene DRD4 that gives us a happy endorphin boost when our rate of prediction error declines. That genetic variant, Hutchinson writes, emerged 40-50,000 years ago, “right around the time when our ancestors began their long, multi-pronged march to the farthest corners of the globe. It was a march, the findings hinted, spurred in part by dopamine.”

Appropriately enough, The Explorer’s Gene will be picked up by many readers as a result of a prediction error. Judging by the title and the historic mountaineering photo on the cover, readers may assume the book is a story of outdoor adventure.

BEIJING (AP) — While China's men's soccer team hasn't generated much excitement in recent years, humanoid robot teams have won over fans in Beijing based more on the AI technology involved than any athletic prowess shown.

Four teams of humanoid robots faced off in fully autonomous 3-on-3 soccer matches powered entirely by artificial intelligence on Saturday night in China's capital in what was touted as a first in China and a preview for the upcoming World Humanoid Robot Games, set to take place in Beijing.

According to the organizers, a key aspect of the match was that all the participating robots operated fully autonomously using AI-driven strategies without any human intervention or supervision.

Equipped with advanced visual sensors, the robots were able to identify the ball and navigate the field with agility

Commuter traffic stops for whales on Australia’s humpback highway

PORT STEPHENS, Australia (AP) — The ferry was late, but not because of the usual traffic. Sydney commuters watched from an idling boat this month as humpback whales the size of buses surfaced nearby, halting the vessel’s passage across the harbor. The curious mammals seemed to be watching them back.

In June and July, it’s not uncommon for whales to stop water traffic in Sydney. Winter heralds the opening of the so-called humpback highway, a migratory corridor along Australia's east coast used by about 40,000 of the massive creatures as they travel from feeding grounds in freezing Antarctica to tropical breeding areas off Queensland state.

“It’s blubber to blubber,” said Dr. Vanessa Pirotta, a wildlife scientist at Macquarie University in Sydney and author of the book “Humpback Highway.” During peak traffic periods the bustling coastal city of 5.5 million people becomes one of the world’s few urban centers where you might see a breaching whale on your morning walk, while buying a coffee, or waiting at a bus stop – anyplace you can see the ocean.
