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...

After 15 years of building North American brand, Winnipeg-based XiteBio Technologies Inc. eyes overseas markets

Out of the laboratory and into farmers’ fields.

If you had to describe Manas Banerjee’s career trajectory in fewer than 10 words, you could do a lot worse than that.

Banerjee is the CEO and founder of XiteBio Technologies Inc., an agricultural biotechnology company based in south Winnipeg, but before that, he was a researcher, scientist and professor at a number of institutions.

After earning a PhD in soil microbiology from the University of Aberdeen in Scotland, Banerjee moved to Canada. He was a post-doctoral fellow at the University of Saskatchewan, a research associate at the University of Manitoba and an adjunct professor at Western University (Ontario), publishing numerous papers and book chapters related to soil science.

Records shattered as summer heat hits Southwest in March; ‘This is what climate change looks like’

WASHINGTON (AP) — The dangerous heat wave shattering March records all over the U.S. Southwest is more than just another extreme weather blip. It’s the latest next-level weather wildness that is occurring ever more frequently as Earth’s warming builds.

Experts said unprecedented and deadly weather extremes that sometimes strike at abnormal times and in unusual places are putting more people in danger. For example, the Southwest is used to coping with deadly heat, but not months ahead of schedule, including a 112 degrees Fahrenheit (44.4 degrees Celsius) reading in two Arizona communities on Friday that smashed the highest March temperature recorded in the U.S. Two places in Southern California also hit that same temperature. All four spots are clustered within about 50 miles (80.5 kilometers) of each other.

“This is what climate change looks like in real time: extremes pushing beyond the bounds we once thought possible,” said University of Victoria climate scientist Andrew Weaver. “What used to be unprecedented events are now recurring features of a warming world.”

March's heat would have been virtually impossible without human-caused climate change, according to a report Friday by World Weather Attribution, an international group of scientists who study the causes of extreme weather events.

Meteorite hunters scour Ohio for fragments of 7-ton space rock that crashed into Earth

MEDINA, Ohio (AP) — Meteorite hunters fanned out across a wide swath of Ohio on Thursday, hoping to collect fragments of an estimated 7-ton (6,350 kilograms) space rock that crashed into Earth this week after a dazzling fireball that was seen from hundreds of miles away.

The meteoroid broke apart around 9 a.m. Tuesday over Valley City, a half-hour south of Cleveland, after it sped through the atmosphere at about 45,000 miles (72,420 kilometers) per hour. It caused a sonic boom that rattled buildings and caused fears of an explosion. The fireball was seen from Wisconsin to Maryland, and NASA confirmed it was a meteoroid nearly 6 feet (1.8 meters) in diameter.

Medina resident December Harris didn’t have to go looking — her cousin and roommate, Ambra Sinclair, found a small black rock they suspect is a meteorite when she was leaving for work. They had heard the sonic boom Tuesday morning but figured it might have been noise from a nearby airport.

Harris said her roommate found the rock in a 4-foot (1.2-meter) area between the garage and the house late Wednesday morning. She described it as somewhat triangular shaped, less than 2 inches (5 centimeters) in diameter — and “very, very black,” with pits on the surface, grooves and a melted texture on its exterior.

‘Extreme’ workouts drive spike in ‘rhabdo’ cases among young N.L. women, says doctor

ST. JOHN'S - Intense workouts and social media pressure are driving a spike in rhabdomyolysis cases in young women in Newfoundland and Labrador, a physician with the province's health authority said Thursday.

Newfoundland and Labrador Health Services said it confirmed about 20 cases in the eastern part of the province in the past six months. Doctors typically expect to see a few cases a year, said Dr. Richard Barter, the clinical chief of emergency medicine in the authority's eastern urban zone.

"The cases that we've seen have been exclusively exertional rhabdomyolysis, and this is when a person takes their physical workouts to an extreme level," Barter said in an interview.

Rhabdomyolysis, or "rhabdo," occurs when muscle tissue is severely damaged and breaks down, leaking enzymes and other substances into the blood. The painful condition can cause urine to turn the colour of black tea and it can lead to kidney damage, Barter said.

Unusual atmospheric river will impact B.C. for days, even after it ends, says expert

VANCOUVER - Emergency officials say residents stranded by an early morning mudslide in Coquitlam, B.C., on Thursday have been safely extracted by helicopter, but a meteorologist warns such slides remain a possibility as an atmospheric river continues to drench the province.

RCMP say they were called to a rural area near the Upper Coquitlam River just after 5:30 a.m. following reports of a mudslide north of the Upper Coquitlam River Park. Coquitlam Search and Rescue said in a social media post that its crews started to rescue residents, who were stranded on the north end of Pipeline Road, just before 10 a.m.

The post said all eight residents, two dogs and one cat living in the area were extracted by a helicopter by 2:45 p.m.

BC Hydro said the slide knocked down a power line, temporarily leaving some 5,000 people without power. The utility expected power to be restored to all affected customers late Thursday or early Friday, but noted crews were having difficulty accessing the damage due to the unstable ground.

David Suzuki is turning 90. Environmentalists may have ‘lost, big time,’ but he still has hope

David Suzuki admits defeat — at least in some respects.

The geneticist-turned-environmentalist, who is days away from his 90th birthday, reflected on his legacy as he prepared to release his latest book, "Lessons from a Lifetime," which compiles photos and stories from his life, as well as testimonials written by those he inspired.

"To me, the important legacy that I want to tell my grandchildren is, look, I tried. I love you. I did the best I could for you. And I tried," he said on a video call last month.

"The measure of a person is not whether they succeeded — because we've lost, environmentalists have lost, big time — but that we tried."

Endometriosis painful, lack of research shameful

Endometriosis is a chronic inflammatory disease that causes debilitating pain, heavy bleeding, extreme fatigue, brain fog and other symptoms. It affects one in 10 women. I am one of them.

Ducks Unlimited provides $1-M pasture for farming research

A Manitoba farming research non-profit will have more space to let cattle roam and graze on prairie grasslands — and study how that foraging affects biodiversity — through a partnership with Ducks Unlimited Canada.

Churchill port could further stunt polar bear growth: U of M researcher

Manitoba’s bold plan to transform the Port of Churchill into a shipping powerhouse could have a negative effect on the area’s treasured polar bear population, which fuels its tourism trade, new research shows.

Oldest known whale recording could unlock mysteries of the ocean

A haunting whale song discovered on decades-old audio equipment could open up a new understanding of how the huge animals communicate, according to researchers who say it’s the oldest such recording known.

Indigenous partnerships key to wildfire preparation

More than 5.3 million acres in Manitoba burned — second only to Saskatchewan — as wildfires raged across Western Canada last summer, and 32,000-plus residents, most of whom were Indigenous, were evacuated from their communities.

In Winnipeg, air quality due to the smoke was so terrible that by August, the year’s poor conditions had broken a 65-year record.

In northern places such as Thompson, the smoke was life-threatening. For most of the summer the city was engulfed in smoke, causing wide-scale lung irritation. Anyone with respiratory conditions like asthma and heart disease was forced to stay indoors.

The fires began after the May 10-11 weekend, when temperatures rose above 35 C, drying the underbrush and creating dangerous conditions.

After 43-year career at the zoo, Janice Martin returns to lend a hand

Armed with a zoology degree from the University of Manitoba, Janice Martin started work at Assiniboine Park Zoo in 1980 and never looked back.

She spent 43 years in various roles at the zoo until she retired in 2023. Retirement, however, was just a long lunch break for Martin. After four months away, she was back as a dedicated volunteer.

“I first started in Aunt Sally’s Farm in the summer of 1976 before going into university in the fall. Right after I graduated, there was an opening at the zoo. It was the perfect opportunity and I grabbed it. I worked my way through different areas over the years, first as a zookeeper, then a supervisor and finally as a curator for 10 years before I retired,” Martin, 68, says.

She volunteers approximately three times a week. For two of those days, she supports the zoo’s enrichment program by creating items to engage and stimulate natural animal behaviour.

Speed limits and safety — follow the science

The premier of Manitoba recently appeared hesitant about collaborating with Winnipeg City Council on a public works proposal to lower the city’s default residential speed limit from 50 km/h to 40 km/h. Without a provincial amendment to the Highway Traffic Act, the city says implementing the change would require installing signs on hundreds of streets, at a cost of up to $10 million to taxpayers.

Years of training keep Artemis II crew mission-ready, researcher says

MONTREAL - Despite the delays for NASA's Artemis II mission around the moon and back, a space medicine researcher says the crew, which includes Canadian astronaut Jeremy Hansen, are physically ready for when the time comes to launch.

"They've been preparing for years, so what is a few more months," said Dr. Farhan Asrar, a physician, space medicine researcher and associate dean at Toronto Metropolitan University's School of Medicine.

"One thing that I've always kind of appreciated and respected in the life of astronauts … is it's always expecting the unexpected and how do you best prepare for that?"

NASA has targeted an April 1 launch for Artemis II, with a six-day launch window running through April 6 announced last week.

Pioneering scientist Suzuki reflects on his life’s work

It is hard to believe that Vancouver’s David Suzuki, an internationally renowned geneticist and environmental activist best-known in Canada for his popular television series The Nature of Things with David Suzuki, turns 90 years old on March 24.

NASA clears its Artemis moon rocket for an April launch with four astronauts following repairs

CAPE CANAVERAL, Fla. (AP) — NASA cleared its moon rocket on Thursday for an April launch with four astronauts after completing the latest round of repairs.

The 322-foot (98-meter) rocket will roll out of the hangar and back to the pad next week at Florida's Kennedy Space Center, leading to a launch attempt as early as April 1. It will mark humanity's first trip to the moon in more than 50 years.

The Artemis II crew should have blasted off on a lunar flyaround earlier this year, but fuel leaks and other problems with the Space Launch System rocket interfered.

Although NASA managed to plug the hydrogen fuel leaks at the pad in February, a helium-flow issue forced the space agency to return the rocket to the Vehicle Assembly Building for repairs, bumping the mission to April.
