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.

Manitobans will continue to spring forward, fall back

Premier Wab Kinew has rejected the idea Manitoba would make daylight time permanent.

British Columbia has announced it will adopt year-round daylight time. The one-hour time change this Sunday — a shift forward — will be the last for most people in that province.

“Not right now,” Kinew said after being asked whether Manitoba would follow suit.

“Everybody’s got an opinion on it, but we only have so many hours in a day, and we’re going to spend those hours on health care and lowering your cost of living.”

Last spring forward for B.C. as it moves to permanent daylight time

VICTORIA - British Columbia's southern population centres will be facing winter sunrises around 9 a.m. — and around 9:30 a.m. in the north — after the decision to adopt year-round daylight time, springing forward by one hour this Sunday for the last time.

Premier David Eby said Monday the decision is about making life easier for families, reducing disruptions for businesses and supporting a stable, thriving economy.

"British Columbians have been clear that seasonal time changes do not work for them,” Eby said.

He announced the change inside the legislature's Hall of Honour, surrounded by about 40 local elementary schoolchildren, and he addressed them first.

Infrequent lunar eclipse performs Copper Side of the Moon early Tuesday morning

Stargazers in Manitoba have the chance Tuesday to watch the last total lunar eclipse on this side of the world until 2029.

Big dreams, cold reality: Buzz builds for Port of Churchill, but risks could outweigh rewards

The marine town of Churchill, cherished for its wildlife, landscapes and history, has recently taken on a new sense of national importance. Plans to expand Canada’s lone deepwater Arctic port on the shores of Hudson Bay have gained momentum — and investment — in the last year as the country looks north for solutions to an unprecedented conflict with its southern neighbour.

Premier Wab Kinew has pitched the Port of Churchill as an answer to Canada’s trade concerns, and a means of galvanizing both provincial and national economies.

Prime Minister Mark Carney has designated a plan to upgrade the port facilities as “transformative,” committing millions in federal dollars to the project and touting its merits in meetings with European trade partners.

In late January, Kinew announced the province was in talks with several companies, including at least one major energy company, about investing in port expansion.

A total lunar eclipse will turn the moon blood red on Tuesday across several continents

NEW YORK (AP) — A blood-red moon will soon grace the skies for a total lunar eclipse — and there won't be another until late 2028.

The spectacle will be visible Tuesday morning from North America, Central America and the western part of South America. Australia and eastern Asia can catch it Tuesday night. Partial stages of the eclipse with small bites taken out of the moon can be seen from Central Asia and much of South America. Africa and Europe will be shut out.

Solar and lunar eclipses happen due to a precise alignment of the sun, moon and Earth. There are between four and seven a year, according to NASA.

The eclipses tend to follow each other, taking advantage of the sweet spot in the celestial bodies' orbits. Tuesday's total eclipse of the moon comes two weeks after a ‘ring of fire’ solar eclipse that dazzled people and penguins in Antarctica.

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.

First Nations awaiting Hydro consults

With licences for two major Manitoba Hydro projects set to expire later this year, affected First Nations await consultation — and want to see change.

Licences for the Churchill River Diversion and Lake Winnipeg Regulation projects, first issued in the 1970s, expire Sept. 1 and Aug. 1, respectively.

The diversion directs water to five stations accounting for roughly 75 per cent of Manitoba’s power generation. The latter project allows Hydro to generate power by manipulating Lake Winnipeg’s water levels.

There is no timeline for the licence renewals, said Environment Minister Mike Moyes. He said that would be dependent on consultations with impacted First Nations.

First Nations hopeful as Hydro’s first Indigenous chair eyes reversing years of enmity

Manitoba Hydro’s first Indigenous board chair says he has reconciliation on his mind as First Nations-driven lawsuits pile up against the Crown corporation and two of its major project licences are set to expire.

“I think there’s a lot of opportunity on the reconciliation side in Manitoba,” said Jamie Wilson, 58, a former treaty commissioner. “The more you understand the history, the more you understand the opportunity.”

Wilson, a member of Opaskwayak Cree Nation, grew up on a farm in The Pas. He remembered neighbours worked at Hydro but didn’t think much about the public utility — just enough to know it kept the house warm in the winter.

Opaskwayak recently took Ottawa to court over a Grand Rapids hydro dam and its impact on band members, CBC reported.

Galápagos park releases 158 juvenile hybrid tortoises on Floreana to restore the ecosystem

FLOREANA ISLAND, Ecuador (AP) — Nearly 150 years after the last giant tortoises were removed from Floreana Island in Ecuador’s Galápagos archipelago, the species made a comeback Friday, when dozens of juvenile hybrids were released to begin restoring the island’s depleted ecosystem.

The 158 newcomers, aged 8 to 13, have begun exploring the habitat they are destined to reshape over the coming years. Their release was perfectly timed with the arrival of the season’s first winter rains.

“They are large enough to be released and can defend themselves against introduced animals such as rats and cats,” said Fredy Villalba, director of the Galápagos National Park breeding center on Santa Cruz Island, noting that the best specimens with the strongest lineage were selected specifically for Floreana.

These released juvenile specimens, out of a total of 700 planned for Floreana, will be introduced gradually. According to Christian Sevilla, director of ecosystems of the Galapagos National Park, they carry between 40% and 80% of the genetic makeup of the Chelonoidis niger —a species that has been extinct for 150 years.

Data centres and infrastructure: an expensive pairing

Governments around the world — India being the latest — have been falling over themselves trying to lure power-hungry, water-thirsty data centre operations to build in their backyards.

Social media companies face legal reckoning over mental health harms to children

For years, social media companies have disputed allegations that they harm children’s mental health through deliberate design choices that addict kids to their platforms and fail to protect them from sexual predators and dangerous content. Now, these tech giants are getting a chance to make their case in courtrooms around the country, including before a jury for the first time.

Some of the biggest players from Meta to TikTok are facing federal and state trials that seek to hold them responsible for harming children's mental health. The lawsuits have come from school districts, local, state and the federal government as well as thousands of families.

Two trials are now underway in Los Angeles and in New Mexico, with more to come. The courtroom showdowns are the culmination of years of scrutiny of the platforms over child safety, and whether deliberate design choices make them addictive and serve up content that leads to depression, eating disorders or suicide.

Experts see the reckoning as reminiscent of cases against tobacco and opioid markets, and the plaintiffs hope that social media platforms will see similar outcomes as cigarette makers and drug companies, pharmacies and distributors.

Fossilized vomit provides insight on predator that lived 290 million years ago

BRANDON — A Brandon University paleontologist has helped identify prehistoric barf that’s nearly 290 million years old — and could be the oldest known example of fossilized vomit from a land-dwelling predator.

Mark MacDougall, an assistant biology professor, was part of a research team that identified 41 bones from at least three animals inside the regurgitated cluster by using CT scans and chemical analysis, the university said in a news release.

Signs point to the vomit coming from a top predator — likely an early relative of mammals — that gulped down a mixed meal that included a small reptile, a fast-moving lizard-like animal and part of a much larger plant-eater, and later coughed it back up.

“It’s rare to get such direct evidence of who was eating whom nearly 300 million years ago,” said MacDougall, co-author of the international study published last month in the journal Scientific Reports.

Manitoba to screen infants for defect that causes sight, hearing problems

Manitoba has become the third jurisdiction in Canada to implement universal newborn screening for congenital cytomegalovirus, which can lead to complications as a child grows up, including hearing loss, vision problems and developmental disabilities.

The delicate art of pressing flowers

When early explorers travelled the four corners of the world in search of botanical treasures and plant knowledge, they faced many challenges collecting and transporting live plant material. In the 19th century, the development of the Wardian case — a glazed box that held soil and water — enhanced the survival rate of live plants on long sea journeys.

But highly detailed botanical illustrations also served as a visual record for early botanists and scientists to study plants from distant parts of the world. The technique of pressing and drying all the parts of individual plants on paper made it possible to preserve plant specimens.

Today, herbariums around the world, including those at Manitoba Museum and the University of Manitoba, house extensive collections of pressed, dried plants stored in specialized, climate-controlled conditions. Scientists use these specimens to determine the rarity of species and understand environmental changes.

Province warns of measles exposure at Jets game as cases surge

Manitoba public health officials are warning attendees of a Winnipeg Jets game they may have been exposed to measles, as the province continues to grapple with outbreaks.

What to know about EPA decision to revoke a scientific finding that helped fight climate change

The Environmental Protection Agency on Thursday revoked its own 2009 “endangerment finding,” a scientific conclusion that for 16 years has been the central basis for regulating planet-warming emissions from power plants, vehicles and other sources.

The finding itself is straightforward: Carbon dioxide and other greenhouse gases — caused by burning fossil fuels such as coal, oil and gas — endanger public health and welfare.

It was adopted after the U.S. Supreme Court ruled in 2007 that greenhouse gases are air pollutants that can be regulated under the Clean Air Act.

The Trump administration says the finding hurts industry and the economy and that the Obama and Biden administrations twisted science to determine that greenhouse gases are a public health risk.

Get vaccinated for flu, COVID-19, measles to protect crowded hospitals: top doc

The province’s top doctor is asking Manitobans to get vaccinated as respiratory virus season threatens to strain hospitals and measles outbreaks tear though parts of Manitoba.

Babies given peanuts, fish, eggs early less likely to become allergic, study affirms

TORONTO - A new Canadian study says giving babies peanuts, eggs, fish and other common food allergens early and consistently decreases the risk they'll be allergic to them.

Senior author Dr. Derek Chu says researchers analyzed more than 190 food allergy studies from around the world to identify the strongest risk factors in developing food allergies.

Their findings, published Monday in JAMA Pediatrics, found that delaying the introduction of peanut-containing foods until babies were over 12 months old doubled their likelihood of becoming allergic to the nut.

The study showed similar results for fish and eggs.

As men’s health enters the national conversation, advocates call for co-operation

OTTAWA - The upcoming launch of a national strategy on men's and boys' health is a positive sign that men's well-being is becoming part of the mainstream conversation in Canada, advocates say — even as they warn that it should not become partisan political fodder.

The Movember Institute of Men's Health and researchers from the University of British Columbia called on the government to launch such a strategy in a report released last summer.

Health Minister Marjorie Michel said she plans to launch a national strategy on men's and boys' health in 2026 by working with colleagues in multiple departments, including Veterans Affairs, Women and Gender Equality and Indigenous Services.

Catherine Corriveau, Movember's director of policy and advocacy, said the government has taken an important first step by acknowledging the problem.
