Will electric tractors gain traction? At a pilot event for farmers, researchers see possibilities

EAST LANSING, Mich. (AP) — In the soft dirt of an indoor horseback riding ring last month, a group of farmers got ready to test drive a new piece of equipment: an electric tractor.

As they took turns climbing in — some surprised by its quick acceleration — they gave real-time feedback to the Michigan State University researchers who have been developing it for over two years.

The farmers remarked on the motor's quiet whir. Most were intrigued, or at least open to the idea. Some were concerned that the battery on the underside of the carriage would mean a lower clearance over the field, while others worried that it would simply be too expensive.

“What we hope to do when we retire is we want to get everything electric on the farm. The tractor is the last electric implement to get,” said Don Dunklee, one of the farmers to provide feedback. He runs a small organic vegetable farm that's relied on wind and solar for decades.

Province creates hunting buffer zone on Bloodvein First Nation

The Manitoba government is creating a buffer zone restricting where non-Indigenous hunters can harvest moose on Bloodvein First Nation’s traditional lands.

Manitoba Natural Resources and Indigenous Futures Minister Ian Bushie announced the change late Monday as moose season began for game hunting areas 17, 17A and 17B that includes the traditional areas of the First Nation, located 285 kilometres north of Winnipeg.

The community, which established a check stop to prevent illegal drugs and contraband from entering the First Nation, warned “outside hunters” on social media weeks ago that they’re not welcome to take moose on their traditional lands.

The Manitoba Wildlife Federation has questioned the First Nation’s authority to block licensed hunters with a moose tag from the area and called on the provincial government to intervene.

Very hungry caterpillars very good for biodiversity

Widely considered a pest and a scourge, a leaf-chomping defoliator dedicated to decimating crops, boring into buds and biting down blossoms as it works to satiate its inexhaustible appetite, a new nature documentary reveals there’s more to the much-maligned caterpillar than meets the eye.

The larval creature takes centre stage in Winnipeg filmmaker Jeff McKay’s documentary feature The Extraordinary Caterpillar.

His hour-long film takes viewers on a journey to understanding why the famously “very hungry caterpillar” is a key player in maintaining biodiversity.

“Caterpillars are right at the centre of the food chain, they are key to the food chain working as it should,” McKay says.

Residents pour cold water on proposed development in St. Vital

Some south St. Vital residents hope to stop a development proposal to build 23 new homes over fears the construction would put their well water at risk.

The proposal aims to add the homes at 45 Daman Farm Rd., 100 Jean Louis Rd. and 2974 St. Mary’s Rd., a 57-acre property on the west side of St. Mary’s Road in the St. Vital Perimeter South neighbourhood. The area is located within city limits but does not have city water and sewer service.

“This particular property lies in a sensitive groundwater area and every well that’s drilled in this area just contaminates the water even further by adding more salt,” said Michelle Olivson, who lives in the area.

City staff recommended the housing application be rejected over the groundwater concerns but city council’s property and development committee voted in favour of the project Friday, echoing a previous community committee vote.

Elon Musk’s Neuralink brain chip implanted into two quadriplegic Canadian patients

TORONTO - Two Canadian patients with spinal cord injuries have received Neuralink brain implants that have allowed them to control a computer with their thoughts.

They are part of the first clinical trial outside of the United States to test the safety and effectiveness of Elon Musk's Neuralink wireless brain chip, which he introduced to the public in 2020, and was first implanted in a paralyzed American in 2024.

The Canadian men, both around 30 years old – one from Ontario, the other from Alberta – have limited or no ability to use their hands.

Dr. Andres Lozano, a neurosurgeon at University Health Network who led the surgical team at Toronto Western Hospital, said the patients could move a computer cursor almost immediately after the surgery. They were able to leave the hospital following their respective procedures on Aug. 27 and Sept. 3 the next morning, he said.

Second summer of motorized boat ban, uncertainty going forward raise longer-term concerns for tourism-driven economy inside Riding Mountain National Park

WASAGAMING — As the sun shimmers over Clear Lake’s still waters, everything appears smooth. But there is an undercurrent of uncertainty running through Manitoba’s most popular national park.

Riding Mountain, and other national parks across Canada, are increasingly facing difficult environmental challenges.

For Riding Mountain, it’s the invasive zebra mussel species. In Alberta’s Jasper National Park, it was 2024’s devastating wildfire that caused more than $1 billion in damages. In Nova Scotia, tinder-dry conditions this summer led to the controversial decision to close back-country access in two national parks — Cape Breton Highlands and Kejimkujik.

This is the new reality for places such as Wasagaming, Riding Mountain’s picturesque townsite that borders on Clear Lake — where bureaucratic decisions to address environmental threats run counter to the desires of residents and tourists who want to enjoy popular summer destinations to the fullest.

One Tech Tip: Ditch the chatbots and take your AI nature apps on a birdwatching hike

I didn't notice the scarlet tanager until the alert appeared on my phone: “Merlin heard a new bird!”

Despite its brilliant plumage — jet-black wings on a crimson body — the songbird can be a hard one to spot in a forest because it prefers to stay high in the canopy. It sounds a little like a robin to an untrained ear.

But the free Merlin Bird ID app detected a scarlet tanager was likely nearby by using artificial intelligence to analyze my phone’s live sound recording. I paused my hike, quietly scanned the treetops, saw the bird as it kept singing and clicked a button to add the species to my growing "life list" of bird sightings. Digital confetti burst on my screen.

Like a real-world version of Pokémon Go, a gotta-catch-'em-all drive to add to my Merlin list has helped me find a great kiskadee in Mexico and a rusty-cheeked scimitar-babbler in the Himalayas. But sometimes the greatest revelations are close to home, as more AI nature app users are starting to discover.

Gardening’s hidden benefits: How digging in the dirt could bolster mental wellbeing

If you spend any time gardening, you probably understand what I mean when I say it feels good — despite the lifting, sweating and straining involved. Yes, exercise is good for our bodies, but there’s something about digging in the dirt while listening to a bird soundtrack that lifts my spirits. Even the scent of the soil and mulch makes me happy.

As it turns out, there are scientific reasons for this.

In fact, there’s an entire field called horticultural therapy that’s dedicated to using “plant-based and garden-based activities to support people who have identified treatment needs,” according to Karen Haney, a horticultural therapy instructor at UCLA Extension in Long Beach, California.

“Research suggests 20-30 minutes (of gardening) a few times a week can reduce stress and lift mood, with benefits increasing the more regularly one gardens,” says Sarah Thompson, a professionally registered horticultural therapist in Boise, Idaho.

McGill University team develops AI that can detect infection before symptoms appear

MONTRÉAL - Researchers at McGill University say they developed an artificial intelligence platform that can predict when someone is about to come down with a respiratory tract infection before they start to feel sick.

In what researchers are calling a "world first," the study involved participants who wore a ring, a watch and a T-shirt, all of which were equipped with censors that recorded their biometric data. By analyzing the data, researchers were able to accurately predict acute systemic inflammation — an early sign of a respiratory infection such as COVID-19.

Published in The Lancet Digital Health, the study says the AI platform can one day help doctors address health problems much earlier than they normally would, particularly in patients who are fragile and for whom a new infection could have serious consequences. It could also potentially reduce costs for the health-care system by preventing complications and hospitalizations.

"We were very interested to see if physiological data measured using wearable sensors … could be used to train an artificial intelligence system capable of detecting an infection or disease resulting from inflammation," explained the study's lead author, Prof. Dennis Jensen of McGill University's department of kinesiology and physical education.

Wildfire smoke changing outdoor sports landscape

Air quality concerns due to wildfire smoke are changing the landscape of sporting events in Winnipeg. From community centre-run programs to professional leagues, outdoor sports have been impacted by smoke delays, cancellations and playing in less than ideal conditions, leading some to rethink how summer outdoor seasons should be planned going forward.

Krista Fraser-Kruck, general manager of Riverview Community Centre in South Osborne, which offers baseball, soccer, softball, ultimate (frisbee) and summer day camps, says wildfire smoke has forced cancellations and caused rescheduling challenges, especially difficult in a short summer season.

“The priority is keeping kids safe,” said Fraser-Kruck. “For our community, we just want to keep our kids safe, and so doing what’s in the best interest of their health is our priority.”

For their youth soccer games, Riverview Community Centre follows the Winnipeg Youth Soccer Association’s policy, which calls for citywide cancellations if Environment Canada’s Air Quality Health Index (AQHI) reaches seven or higher.

More than 7,000 elms felled in Winnipeg last year due to disease

A city report reveals elm trees were chopped down more than expected last year due to Dutch elm disease.

Should you let pets sleep next to you? (Does it even matter what the experts say?)

It turns out, our furry best friend might be our sleep enemy.

Lots of pet owners let their animals sleep on the bed with them, which usually disrupts sleep. But many would say it’s worth it.

And researchers don't necessarily disagree.

Melissa Milanak, a professor at Medical University of South Carolina specializing in sleep health, said most people at her clinic say their pets disturb them often at night.

CDC removes language that says healthy kids and pregnant women should get COVID shots

NEW YORK (AP) — The nation's top public health agency posted new recommendations that say healthy children and pregnant women may get COVID-19 vaccinations, removing stronger language that those groups should get the shots.

The change comes days after U.S. Health Secretary Robert F. Kennedy Jr. announced that COVID-19 vaccines will no longer be recommended for healthy children and pregnant women.

But the updated guidance on the Centers for Disease Control and Prevention's website sends a more nuanced message, saying shots “may” be given to those groups.

“The announcement from earlier this week sounded like CDC was going to fully withdraw any statement that could be construed as a recommendation for these vaccines in these populations,” said Jason Schwartz, a Yale University health policy researcher. “It's not as bad as it could have been."

Dive-bombed or not, Vancouverites are still pro-crow, researchers say

VANCOUVER - Along her journey towards understanding Vancouver's crows, psychology professor Suzanne MacDonald says she made a friend.

It's a crow that brings her gifts after she set up a bird feeder at her home in the neighbourhood of Kitsilano.

Once, it was a barnacle-covered shell, which MacDonald treasures. Other times, it was "bits of garbage" that MacDonald doesn't fancy much, though she "appreciates the sentiment."

"I think he definitely recognizes me. When other people go out on my patio, he doesn't come to them. He knows me," said MacDonald.

Publix recalls baby food pouches after testing finds elevated levels of lead

The supermarket chain Publix has recalled fruit and vegetable baby food sold in eight states because product testing found elevated levels of lead, according to federal health officials.

Publix recalled 4-ounce Greenwise Pear, Kiwi, Spinach & Pea Baby Food pouches sold at more than 1,400 stores.

The pouches were produced by Bowman Andros, a French company with a manufacturing plant in Mount Jackson, Virginia, according to the company's website. Publix issued the voluntary recall on May 9, but it wasn't added to the U.S. Food and Drug Administration recall list until late Thursday.

The potential contamination was flagged by officials in North Carolina, the state that first identified a 2023 lead poisoning outbreak linked to tainted applesauce pouches that sickened more than 500 U.S. children.

Getting river rehab rolling: Other cities' success in stemming effluent offer splashes of hope for Winnipeg's waterways

From giant cisterns to rain gardens, storage tunnels and parks, cities across Canada — and the rest of the world — have shown there are plenty of options to stop the overflow of sewage into freshwater.

Locally produced renewable energy is the right call

At the start of Premier Wab Kinew’s government’s mandate, it signalled it would work to get Manitoba to a net-zero electricity grid by 2035. With 99 per cent of the province’s electricity already emissions-free, it is a small, but important gap to bridge.

Some doctors sneak education into their online content to drown out misinformation

TORONTO - When Dr. Siobhan Deshauer makes online videos, her primary goal is to demystify medicine. Her secondary goal?

"I call it 'smuggling in education,'" said the physician and YouTuber, who boasts nearly a million subscribers on the platform. "You're coming for this mystery and this excitement, but I'm smuggling in some topics that I think are really important and that I'm passionate about."

Some experts say one of the best ways to fight a rising tide of medical misinformation on social media is to drown it out with captivating content backed by science, and Deshauer, an Ontario-based internal medicine and rheumatology specialist, is among a growing cohort of doctors and researchers doing just that.

Take one of her medical mystery videos, for example. In it, Deshauer tells the story of a woman who had lead poisoning. Doctors took ages to figure out what was causing her symptoms, but ultimately realized they were a result of lead in the Ayurvedic supplements she was taking.

'Cheering for the mammoth': Scientists retrace the steps of 17,000 year-old animal

More than 17,000 years ago, a woolly mammoth roamed enough of the Alaskan landscape to circle the Earth twice.

That's according to a new paper from an international team of researchers who retraced the lifetime of one of the extinct ancient Arctic creatures.

The mammoth's story is written in its tusk through tiny isotopes, which are tiny atoms, said Mat Wooller, a paleoecologist at the University of Alaska.

"Isotopes are like a little chemical GPS (global positioning system) recorder," Wooller said.

Locals find loophole in laws of physics

A University of Winnipeg scientist leads an international team of researchers who may have found a loophole in the laws of physics.

Magnetricity could have practical applications down the road to store data in computers or conduct electricity, said U of W chemistry Prof. Chris Wiebe.

"All of magnetic (knowledge) is based on 'You can't have a single pole,' " explained Wiebe, a graduate of the U of W and Transcona Collegiate. There is always a north pole and a south pole, and a single pole cannot occur naturally.

So say the laws of physics, but...
