'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.

Pit bulls legal, ball pythons banned?

Laura Baker has wanted a pit bull for 20 years, but hasn’t bought one because of the city’s ban.

“I just feel like the whole breed has been so misrepresented, misunderstood and given a raw deal in terms of being able to find loving homes,” the St. James resident said.

If proposed changes to a city bylaw pass, Baker will legally be able to own a pit bull, while it could become illegal to feed wildlife and to leave pets in vehicles at certain temperatures.

The city is looking for feedback on suggestions to its Responsible Pet Ownership bylaw. Winnipeg Public Service reviewed the rules this summer and came back with a number of ideas, including a removal of breed-specific bans.

Chasser, pour avoir la conscience tranquille

Vanessa Ahing a été végétarienne pendant plus de quatre années. Par refus de l’industrie de la viande qui, à son avis, est cruelle et nuit à l’environnement. Pourtant, un bon steak lui manquait. Pour réconcilier conscience et palais, un choix nouveau s’imposait...

Un soir de septembre, 2013, Vanessa Ahing rentrait de la campagne, où elle avait abattu son premier chevreuil. Souvenir de l’enseignante de 31ans: “J’étais toute seule. J’avais suivi une formation de chasse pour femmes, organisée par la Manitoba Wildlife Foundation. Mon chevreuil, coupé en quarts, était dans un sac de hockey dans le coffre de ma Honda Civic. C’était mon premier animal. Je voulais vivre l’expérience complète de la chasse. Donc pas question pour moi d’aller chez un boucher. D’ailleurs, j’étais étudiante. Je n’avais pas le fric pour me payer un tel service.

“Je me demandais comment j’allais faire pour préparer cette viande. Je n’ai pas été élevée dans une famille de chasseurs, ou même de jardiniers. Mes parents n’étaient pas prêts à avoir un chevreuil chez eux. Et moi, je vivais dans un petit appartement pour célibataires au centre-ville de Winnipeg.

“Il était tard. Trop tard pour dépecer l’animal tout de suite. Alors, j’ai ouvert les fenêtres de mon appartement. Je me suis endormie dans mon sac de couchage. Le lendemain, j’ai tapé ‘Comment couper de la viande de chevreuil’ sur YouTube. Et je me suis mise à l’œuvre.”

Investors behaving badly

Finance professor Chi Liao’s background in mathematics often comes in handy in her line of work.

After all, both corporate and investment finance are built upon numbers. Yet financial reporting — balance sheets and cash-flow analysis — is not her area of interest.

In fact, her expertise has less to do with the numerical side of money and more to do with how our emotions affect how we manage our hard-earned cash.

“I’ve always been fascinated by people-watching and why it is we do what we do,” says Liao, who studied mathematics and finance before completing a PhD in behavioural finance from the University of Toronto in 2014.

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.

‘Fly WestJet, see a UFO’

The truth is out there — or at least it could be outside the cockpit of a WestJet flight.

In an incident reported by NAV Canada to Transport Canada on Friday, WestJet pilots had reported they had flown by “a basketball-sized object at 13,000 feet” during a flight from Winnipeg to Calgary on Jan. 19.

The pilots, of flight WJA485, were flying just northwest of Canmore at the time and descending to land in Calgary when the incident occurred.

NAV Canada has classified the incident, under occurrence event information, as a “weather balloon, meteor, rocket, CIRVIS/UFO.” CIRVIS stands for Communications Instructions for Reporting Vital Intelligence Sightings.

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.

Winnipeg and ground squirrels

In a move shocking to many local animal lovers, the City of Winnipeg has opted to go ahead with its plan to kill ground squirrels at nine city parks and fields via methods that animal advocates say will cause prolonged pain and suffering.

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.
