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.

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...

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

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

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.”

Better protection needed for urban trees

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.

City non-profit inks deal with subsidiary of leader in phosphate-based fertilizers

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.

Steinbach, nearby communities flooded in massive overnight deluge

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.
