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.

King penguins are the rare species benefiting from a warming world. But that could change

WASHINGTON (AP) — The warming world has disrupted the timing for plant and animal reproduction, and it's usually bad news for species that depend on each other — like flowers blooming too early and pollinating bees arriving too late. But researchers have found the rare critter that's getting a boost from the change: King penguins.

A new study of 19,000 king penguins in a sub-Antarctic island chain found their breeding is starting 19 days earlier than it did in 2000. Mating earlier has increased the breeding success rate by 40%, according to a study in Wednesday's journal Science Advances.

The study of timing in nature is called phenology. It's been a major concern for biologists because predators and prey and pollinators and plants are mostly adapting to warmer climates at different rates. And that means crucial mismatches in timing.

It's especially common in birds and pollinating species such as bees. Most birds, especially in North America, aren't keeping pace with changes in phenology, according to Clemson University biological sciences professor Casey Youngflesh, who wasn't part of the study.

‘Uncover what’s really going on’: UFO researcher in Manitoba supports AI tracking

WINNIPEG - Artificial intelligence is going to make it easier to spot whether a bird, a plane or an otherworldly creature is in the sky, as Canadians continue to report sightings of unidentified flying objects, says Canada's top UFO expert.

Chris Rutkowski has spent decades researching the phenomenon and is part of Ufology Research, a Manitoba-based organization that tracks UFO sightings in Canada and publishes an annual report.

The group's 2025 analysis, released Monday, includes data taken from observation stations set up by passionate UFO enthusiasts across the country.

"They're gathering scientific data above and beyond just the average person seeing something in the night sky. This is an attempt to quantify UFO sightings," said Rutkowski.

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.

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.

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.

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.

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.

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.

Manitoba has most measles cases in Canada — and it’s likely much worse, doctors say

Manitoba has the country’s highest number of reported measles infections in 2026 — a year after the province’s outbreak began — while a surge brings stronger messaging from the government.

Dr. Davinder Singh, who is Manitoba’s public health lead on measles, said the province is seeing its highest monthly totals since May.

“Unfortunately, we’re seeing an increase in the number of detected or reported cases. We also know the number of cases that are diagnosed are only a relatively small fraction of the true number of cases out in the community,” he said Wednesday.

“We can estimate that there may be about 10 times as many infections as we have that get reported to us or that get detected.”

First Nation says Hydro misuse of river diversion destroying sturgeon population

A northern First Nation is calling on Manitoba Hydro to alter its use of the Churchill River diversion to protect a lake sturgeon population allegedly decimated by hydroelectric operations.

Tataskweyak Cree Nation Chief Doreen Spence said the culturally significant species is facing extinction on the river system without immediate intervention, 50 years after Manitoba built the diversion to send water to large power generating stations.

“The diversion has artificially altered the flow of the water… so much that the river is barely able to sustain life as it once did,” Spence told reporters in Winnipeg Thursday.

“Manitoba Hydro must operate the diversion in sync with the natural flow regime of the river for the sturgeon to survive.”

Manitoba enterprise at forefront in bolstering soil structure

Soil health has always been important to anyone who wants to grow plants that flourish but never more so than today. Soil degradation due to drought and extreme weather is a global problem that has a direct link to agricultural productivity and food security.

The status of soil health in Canada is not a concern limited to farmers and backyard gardeners. Scientists, policy makers and researchers are recommending urgent action to protect soils to safeguard the future of our food production.

In June 2024, following an 18-month study of soil conditions in Canada, the Standing Senate Committee on Agriculture and Forestry released the report Critical Ground: Why Soil is Essential to Canada’s Economic, Environmental, Human and Social Health. The report, which is based on testimony from more than 150 experts, concluded that soil in our country is at risk, with implications for food production, climate resilience and biodiversity.

Dale Overton takes soil health and its implications for fertility and food production seriously. His company, Overton Environmental Enterprises, manufactures several microbial products for large-scale agriculture as well as for the home gardener. Overton is deeply interested in regenerative farming practices and how biological amendments can benefit soil health, carbon sequestration and soil microbiomes, and boost growth rates and crop yields.

Skating trail expected to open in time for New Year’s Day activities at The Forks

Skaters, rejoice: the Nestaweya River Trail at The Forks could be open as early as New Year’s Day, marking one of its earlier openings in recent years.

The port rink on the Assiniboine River and a small section of the the iconic river trail opened on Dec. 31 last year. The earliest recorded opening of the six-kilometre skating trail was Dec. 21, 2013.

“We had a good freeze this year… and we’re hoping for a nice, long season this year,” Adam Dooley, spokesperson for The Forks, said Monday.

Sections of the trail, which snakes along the Red and Assiniboine rivers and meets at The Forks port, have some slush owing to recent snowfall and may take more time to open, Dooley said.

U of M researchers studying whether genetic testing helps zero in on effective mental-health treatment meds

A team of University of Manitoba researchers is recruiting people seeking mental-health treatment for a study that could take the guesswork out of medication with the help of genetic testing.

The study will offer free pharmacogenomic testing — which predicts how a person may react to medications based on their genetic makeup — to 200 adults who are looking to start a new medication or switch their medication treating a mental-health issue.

“Someone with mental-health conditions, they (try) multiple medications, and sometimes it takes months or years to get to a point where those drugs work for them, or to have less side effects,” said Dr. Abdullah Maruf, the lead investigator on the study and assistant professor in U of M’s College of Pharmacy.

“Pharmacogenomic testing can find out how our body will respond to these kinds of medication.”

Killer whales and dolphins may be helping each other hunt of B.C. coast: new report

HALIFAX - Scientists have found evidence that two unlikely collaborators — killer whales and dolphins — may be helping each other find and feast on salmon off the coast of British Columbia.

Sarah Fortune, an assistant professor in oceanography at Halifax’s Dalhousie University said it would appear the massive fish-eating whales may be working with Pacific white-sided dolphins, which have been spotted eating the salmon chunks the killer whales produce.

She is a co-author of a paper published Thursday in Scientific Reports that found the two species appear to be working together while they forage.

Recordings picked up "this audible crunch as the whale bites down, then you see these fragments of fish that are released,” and then dolphins swim in to eat the pieces, Fortune said.
