Few food innovations as polarizing as genetic modification

Laura Rance 4 minute read Saturday, Apr. 11, 2026

Most of us have been eating foods derived from genetically modified crops for a generation or so, and so far, none of the ills attributed to modern food systems have been traced back to their use.

Except, perhaps our propensity towards overeating.

Since their introduction in the mid-1990s, genetically modified crops have taken over nearly half of the global area sown to soybeans, canola and corn.

The foods from these varieties, which are most often genetically modified to allow farmers to use herbicides that kill weeds but not the crop, are the same as traditional varieties in every measurable way.

Motorboats to return to Clear Lake this summer

Connor McDowell 5 minute read Wednesday, Apr. 8, 2026

Motorboats will be allowed to return to Clear Lake this summer, a year after they were banned amid the discovery of invasive species.

Parks Canada officials said Wednesday watercraft inside the Riding Mountain National Park lake would be permitted under a mandatory tagging program and several other conditions.

“We’re pleased, but we also want to see how it will be implemented,” said Trevor Boquist, spokesperson for the Fairness for Clear Lake advocacy group.

“I would say we want to be part of the conversation of how this will be implemented.”

Artemis II astronauts make long-distance call to the space station as they head home from the moon

Marcia Dunn, The Associated Press 4 minute read Wednesday, Apr. 29, 2026

HOUSTON (AP) — Still aglow from their triumphant lunar flyby, the Artemis II astronauts made more history Tuesday: calling their friends aboard the International Space Station hundreds of thousands of miles away as they headed home from the moon.

It was the first moonship-to-spaceship radio linkup ever. NASA's Apollo crews had no off-the-planet company back in the 1960s and 1970s, the last time humanity set sail for deep space.

"We have been waiting for this like you can’t imagine,” Artemis II commander Reid Wiseman called out.

For Christina Koch on Artemis II and Jessica Meir aboard the space station, it marked a joyous space reunion despite being 230,000 miles (370,000 kilometers) apart. The two teamed up for the world's first all-female spacewalk in 2019 outside the orbiting lab.

NASA released new photos Tuesday captured by the Artemis II astronauts.

Artemis II’s lunar fly-around and intense observation period lasted seven hours.

A total solar eclipse greeted the three Americans and one Canadian as the moon temporarily blocked the sun from their perspective.

Venturing as close as 4,067 miles (6,545 kilometers) to the gray dusty surface, the astronauts zipped through a list of more than two dozen photo targets, using powerful Nikon cameras as well as their iPhones to zoom in on impact craters and other intriguing lunar features.

Energy-hungry Nova Scotia companies nearly doubled their solar power capacity in 2025

Devin Stevens, The Canadian Press 5 minute read Wednesday, Apr. 29, 2026

HALIFAX - Energy-hungry companies in Nova Scotia are heading toward the light.

New statistics from the province's private power utility show that commercial-scale players — which includes municipalities and First Nations — grew their capacity to generate solar energy by 82 per cent last year.

Energy consultant David Brushett says that’s partly because legislative changes a few years ago have allowed companies to install solar systems 10 times larger than before. The “net-metering” system gives firms a credit on their power bills for the electricity they generate, offsetting their own usage. Even with the new rules, they are not allowed to generate more power than their operations consume.

The program allows solar projects of up to one megawatt for commercial customers. Brushett says that size makes more financial sense. “So that allowed much larger installations,” Brushett said in an interview.

The Latest: Artemis II astronauts reach orbit on historic mission to the moon and back

The Associated Press 22 minute read Saturday, Apr. 25, 2026

Four astronauts embarked on a high-stakes flight around the moon Wednesday, humanity’s first lunar voyage in more than half a century and the thrilling leadoff in NASA’s push toward a landing in two years.

NASA's launch team loaded more than 700,000 gallons of fuel into the 32-story Space Launch System rocket early Wednesday, setting the stage for blast off in the evening at Kennedy Space Center in Florida.

Artemis astronauts Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen are on board. They’ll hurtle several thousand miles beyond the moon, hang a U-turn and then come straight back. No circling around the moon, no stopping for a moonwalk — just a quick out-and-back lasting less than 10 days. NASA promises more boot prints in the gray lunar dust, but not before a couple practice missions.

Unlike the Apollo missions that sent astronauts to the moon from 1968 through 1972, Artemis’ debut crew includes a woman, a person of color and a Canadian citizen.

‘Long overdue’: Prairie farmers welcome renewal of poison to target pesky gophers

Jeremy Simes, The Canadian Press 5 minute read Tuesday, Apr. 28, 2026

Prairie farmers say a move by Ottawa to temporarily lift a ban on a rodent poison is a good start to address rampant gopher populations that have decimated crops and injured livestock.

"I suspect maybe if the Bible had been written in Saskatchewan, it wouldn't have been locusts. It would have been gophers," Jeremy Welter, a farmer near Kerrobert, Sask., said Tuesday.

"I think (lifting the ban) is one of those things that is long overdue."

On Monday, federal Health Minister Marjorie Michel and Agriculture Minister Heath MacDonald announced producers can again start using two per cent liquid strychnine until November 2027 to control gophers, also known as Richardson's ground squirrels.

Federal government taking over vaccine injury compensation, aims to address backlog

Sarah Ritchie, The Canadian Press 5 minute read Tuesday, Apr. 28, 2026

OTTAWA - The federal public health agency is taking over administration of a program that compensates people who have been injured by vaccines, and pledging to review claims that were refused by a third-party administrator for being filed too late.

The vaccine injury support program began accepting claims in June 2021, after the widespread rollout of the COVID-19 vaccine in Canada.

People who experienced a "serious and permanent injury" as a result of receiving a vaccine authorized by Health Canada after Dec. 8, 2020, are eligible to make a claim.

It's also been the subject of complaints from claimants who say the process is slow and communication is poor.

‘Good day to be a polar bear’: Carney unveils nature strategy, new conservation areas

Nick Murray, The Canadian Press 4 minute read Tuesday, Apr. 28, 2026

LA PÊCHE - The Liberal government's new $3.8 billion nature protection strategy will put Canada's 2030 nature conservation goals within reach, Prime Minister Mark Carney said Tuesday.

Announcing the new plan at an event in Wakefield, Que., Carney said the federal government will create new national parks, urban parks and marine conservation areas.

Carney said his government is taking an "ambitious" approach to conservation spaces and urban parks. He said the plan will require "significant" federal funding and includes aspirations to spur private-sector investments.

The new conservation areas will include the Wiinipaawk Indigenous protected area and national marine conservation area in Eastern James Bay, and the Seal River watershed national park in Manitoba.

"He wants me out of there, to shut up," Bourassa said in an interview. "That's bullying and I'm not falling for that.

‘Fly WestJet, see a UFO’

Kevin Rollason 2 minute read Saturday, Mar. 21, 2026

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

Patrick Aftoora-orsagos And Mark Scolforo, The Associated Press 4 minute read Friday, Apr. 24, 2026

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

The Canadian Press 3 minute read Friday, Apr. 24, 2026

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.
