New football chinstrap designed to lessen force of blows to facemask

Erin Hanson wants to make taking it on the chin in football much safer in Canada.

Guardian Sports officially launched the Guardian Flex chinstrap on Thursday for individual and team sale, with the CFL being among the leagues to have reviewed the item. The product has been engineered to reduce the impact of blows to the facemask.

According to the company, the chinstrap reduces Head Acceleration Response Metric (HARM) scores by up to 35 per cent and targets facemask impacts, which research suggests account for about half of all hits and are an area where traditional helmets underperform.

The chinstrap will be far less noticeable to fans than the Atlanta-based company’s Guardian Cap. Introduced 14 years ago, the soft padded shell fits over a football helmet and is secured by elastic straps attached to the facemask.

City report recommends reducing residential speed limit to 40 km/h

Winnipeg drivers may have to ease up on the gas pedal when they head down residential streets and minor collector roads.

The City of Winnipeg is looking at making the default speed limit 40 km/h, from the current 50 km/h.

A report to be presented to the public works committee next week suggests the change could improve safety for pedestrians, cyclists and others.

Committee chair Coun. Janice Lukes says she supports the recommendation, but stressed amendments to the provincial Highway Traffic Act are required before it could take effect.

The surprising complexity behind the squeak of basketball shoes on hardwood floors

NEW YORK (AP) — As he watched the Boston Celtics play from the stands of TD Garden, one noise kept catching Adel Djellouli's ear.

“This squeaking sound when players are sliding on the floor is omnipresent,” he said. “It’s always there, right?”

Squeaky shoes are part of the symphony of a basketball game, when rubber soles rasp against the hardwood floors as players jab step, cut and pivot and defenders move their feet to stay in front of their assignment.

Returning home from the game, Djellouli wondered how that sound was produced. And as a materials scientist at Harvard University, he had a way to find out.

More Canadian athletes powered by artificial intelligence at Winter Games

Just for fun, Xavier McKeever and his cross-country ski teammates once tasked ChatGPT to design a training plan for them.

"It was the craziest training plan we've ever seen," said the 22-year-old from Canmore, Alta.

"It basically said you should do intensity every single day. You should do three hours of skiing and then an hour of intensity, and repeat that a few times -- and then you should take a week off completely. We know you can't do that.

"It was pretty funny to see and do, to see Chat GPT can't write a training plan, and that we need our coaching to help us with that."

Three scientists at US universities win Nobel Prize in physics for advancing quantum technology

STOCKHOLM (AP) — Three scientists won the Nobel Prize in physics Tuesday for research on the strange behavior of subatomic particles called quantum tunneling that enabled the ultra-sensitive measurements achieved by MRI machines and laid the groundwork for better cellphones and faster computers.

The work by John Clarke, Michel H. Devoret and John M. Martinis, who work at American universities, took the seeming contradictions of the subatomic world — where light can be both a wave and a particle and parts of atoms can tunnel through seemingly impenetrable barriers — and applied them in the more traditional physics of digital devices. The results of their findings are just starting to appear in advanced technology and could pave the way for the development of supercharged computing.

The prizewinning research in the mid-1980s took the subatomic “weirdness of quantum mechanics” and found how those tiny interactions can have real-world applications, said Jonathan Bagger, CEO of the American Physical Society. The experiments were a crucial building block in the fast-developing world of quantum mechanics.

Speaking from his cellphone, Clarke, who spearheaded the research team, said: “One of the underlying reasons that cellphones work is because of all this work."

Ski jumper Mackenzie Boyd-Clowes takes to the air again for Canada

CALGARY - Mackenzie Boyd-Clowes has returned to ski jumping after a hiatus of two and a half years.

Boyd-Clowes laid down Canada's final jump of the mixed team event at the 2022 Winter Games for bronze and the country's first ever Olympic medal in the sport.

The four-time Olympian is back in the air again. Boyd-Clowes competed in a pair of September competitions and provisionally qualified for the 2026 Winter Games in Milan and Cortina, Italy.

"It's new and fresh and exciting. I took a long break and wasn't sure whether I would jump again and now I'm doing it," Boyd-Clowes said.

Rogers wins gold, sets Canadian record in hammer throw at world championships

TOKYO - Camryn Rogers set the tone early in the women's hammer throw at the world athletics championships Monday with an impressive opening toss of 78.09 metres.

Good enough for a world title. Not good enough for Rogers.

The 26-year-old from Richmond, B.C., put the competition out of reach with her second throw of 80.51 metres to claim her second straight world championship gold medal in dominant fashion.

Rogers's winning throw broke her own Canadian record and is the second longest ever behind the world record of 82.98 set by Poland's Anita Wlodarczyk in 2016. Rogers's previous personal best was 78.88 metres.

Le centre d’interprétation Saint-Léon: là où souffle l’esprit de la nature et de l’innovation

Avec ses galeries interactives, ses sentiers en pleine nature et son riche contenu éducatif, le Centre d’interprétation Saint-Léon est bien plus qu’un simple musée rural. En 2025, la communauté célèbre les 20 ans du premier parc éolien du Manitoba — une réalisation marquante racontée au cœur du Centre. Entre salamandres mystérieuses, énergies vertes et oiseaux migrateurs, les visiteurs y découvrent un territoire où science, nature et fierté locale se rencontrent.

Situé près du lac Saint-Léon, le Centre d’interprétation Saint-Léon a toujours eu pour vocation d’éduquer les curieux, qu’ils soient touristes ou de la région, mais aussi de rassurer. Lorraine Mabon, la présidente, raconte:

“Le but original, c’était de parler des salamandres et de leur rôle, parce qu’il y en avait énormément dans la région et les gens en avaient un peu peur. Mais les salamandres, qu’on trouve sur les terres humides, sont une bonne chose: elles sont indicatrices de la bonne santé de l’environnement.

“Un autre fait intéressant, c’est que si elles perdent un membre, elles peuvent le régénérer! Beaucoup de scientifiques étudient cette faculté exceptionnelle.”

FAA demands an accident investigation into SpaceX’s latest out-of-control Starship flight

CAPE CANAVERAL, Fla. (AP) — The Federal Aviation Administration is demanding an accident investigation into this week’s out-of-control Starship flight by SpaceX.

Tuesday's test flight from Texas lasted longer than the previous two failed demos of the world's biggest and most powerful rocket, which ended in flames over the Atlantic. The latest spacecraft made it halfway around the world to the Indian Ocean, but not before going into a spin and breaking apart.

The FAA said Friday that no injuries or public damage were reported.

The first-stage booster — recycled from an earlier flight — also burst apart while descending over the Gulf of Mexico. But that was the result of deliberately extreme testing approved by the FAA in advance.

Alexander Zverev says lightning struck his flight to Paris for the French Open

PARIS (AP) — German tennis player Alexander Zverev said Friday his plane was hit lightning on the way to Paris for the French Open and had to turn around, delaying his arrival for the clay-court Grand Slam tournament.

He wound up getting in at about 3 a.m.

“We were supposed to fly yesterday evening at 6:45 p.m., and we took off from Hamburg,” said Zverev, last year's runner-up at Roland-Garros and seeded No. 3 this year. “We got struck by lightning. We had to do an emergency landing back in Hamburg.”

By the time he got on a different flight, his journey resumed at 1 a.m.

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...

‘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.

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.

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.

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.

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.

Spacecraft’s impact changed asteroid’s orbit around the sun in a save-the-Earth test, study finds

CAPE CANAVERAL, Fla. (AP) — An asteroid that NASA used for target practice a few years ago was nudged into a slightly different route around the sun, findings that could help divert a future incoming killer space rock, scientists reported Friday.

It’s the first time that a celestial body’s orbit around the sun was deliberately changed. The asteroid that NASA's Dart spacecraft slammed into was never a threat to Earth.

“This study marks a notable step forward in our ability to prevent future asteroid impacts on Earth,” the international research team wrote in Science Advances.

The changes were slight — reductions of just one-tenth of a second and one-half of a mile (720 meters) to a solar lap spanning two years and hundreds of millions of miles (kilometers), according to the scientists.

No chance asteroid will slam into the moon in 2032, NASA says

CAPE CANAVERAL, Fla. (AP) — NASA issued a welcomed all-clear Thursday, saying there's now zero chance that asteroid 2024 YR will crash into the moon in 2032.

The space agency had been predicting a 4.3% chance of a direct hit. But observations by the Webb Space Telescope in February helped scientists refine the asteroid’s orbit.

This new information indicates that the asteroid will miss the moon by 13,200 miles (21,200 kilometers) on Dec. 22, 2032.

Discovered at the end of 2024, the asteroid at first looked like it might threaten Earth. Scientists last year ruled out a collision with our planet anytime in the next century, but kept the moon as a possible target. The asteroid is about 200 feet (60 meters) across.

Proposal to reduce Winnipeg’s default 50 km/h speed limit advances

A proposal in which Winnipeg drivers would be forced to slow down on residential streets is rolling forward.

On Wednesday, council’s public works committee voted to ask the provincial government to change the Highway Traffic Act, pending a final council vote. The change would give the city the power to alter the 50 km/h default speed limit for Winnipeg that applies to all areas, except where signs post a different speed limit.

Following that, city staff recommend that council reduce the default speed limit to 40 km/h for residential streets and “minor collector” streets.

Coun. Janice Lukes said she’d support the reduced speed limit in residential areas, which she expects would only create a minor delay for drivers.

Councillors back permanent bike lane for Wellington Crescent next year

The city is poised to scrap a long-awaited temporary bike lane pilot project on Wellington Crescent, which was expected this year, and speed up the construction of permanent bike lanes instead.

On Wednesday, council’s public works committee voted to accelerate the plan to construct permanent bike lanes in 2027, pending a final council vote. The city had planned to spend $5.5 million to do so in 2029.

Coun. Janice Lukes, chairwoman of public works, said the switch to pursue permanent protected bike lanes, with curbs to separate cyclists from vehicular traffic, is the best way to ensure lasting safety improvements.

“This is going to be a fundamental change in the way traffic moves, pedestrian cycling and vehicular traffic in this section, and I want to rip the Band-Aid off once… It’s going to be a big change for everyone,” said Lukes (Waverley West).

Councillor calls for permanent bike lanes on Wellington stretch

The chair of Winnipeg’s public works committee wants the city to scrap plans for temporary bike lanes on part of Wellington Crescent and immediately proceed with a permanent protected route.

Coun. Janice Lukes wants permanent lanes to be installed in 2027 if her proposal is approved, although some proponents worry there will be more delays if plans change for a road they consider unsafe.

“I know this is frustrating and it’s challenging, but we’ve got the money — move it up and let’s just do it right the first time,” Lukes told reporters.

The city on Wednesday published a staff report and design for temporary lanes on a one-kilometre section between Academy Road and Stradbrook Avenue, after getting public input on a proposed $436,000 pilot project.

Tony Hawk, Mark McMorris help open skateboard park expansion in Smithers, B.C.

Tony Hawk and Mark McMorris wanted their presence at the Smithers Skate Park expansion unveiling to amplify skateboarding's importance in the remote, northern B.C. community.

Skateboarding icon Hawk and Canadian snowboarding star McMorris travelled to the town of 5,000 people for Thursday's opening. They lauded the community's pluck in raising $1.8 million to increase the size of the street park and build a bowl for skateboarders next to the Yellowhead Highway that runs from Winnipeg to the West Coast.

"I don't go to many grand openings, to be honest, but this seemed like a really unique situation," Hawk said. "I don't want to say it's the most remote area, but in remote areas, skateboarding is still a valid option for kids to choose, and they want to do it. We need to provide facilities for them."

McMorris, a three-time Olympic slopestyle bronze medallist whose 24 X Games medals is the most among snowboarders, has a special place in his heart for skateboarding.

Josef Newgarden fastest in final Indy 500 practice. Takuma Sato and other contenders have problems

INDIANAPOLIS (AP) — Josef Newgarden spent the final 2-hour practice for the Indianapolis 500 on Friday carving through a track full of cars.

He'll have to do the same thing when it counts on Sunday.

The two-time defending Indy 500 winner, who will start in the last row as punishment for an illegally modified part found during qualifying, had the fastest lap of the 2-hour final practice on Carb Day at 225.687 mph. Teammate Will Power, who will also start at the back, was fifth while fellow Team Penske driver Scott McLaughlin was just 27th on the chart.

“We have the tools and the people to battle to the front,” Newgarden said, “which is what we plan to do.”
