Alberta lets the dogs out, recruits more canine muscle in fight against mussels

CALGARY - Hilo, Jane and Winnie are a part of Alberta's muscle against invasive mussels that have spread throughout the Great Lakes and Canadian waterways since the 1980s.

So far, species of invasive mussels haven't made their way into Alberta, and the canines work among human teams that scan boats entering the province to maintain that streak.

But the threat is nearing, with golden mussels just recently established in California, said Cindy Sawchuk, the lead for the province's Aquatic Invasive Species Operations and Conservation Canine Program.

"These mussels really like to hide in damp, dark places (and) a lot of them are hard to see," said Sawchuk, emphasizing their small size.

Human-caused climate change made Spanish, French fires much more likely, scientists calculate

Climate change's fingerprints are all over the extreme fire weather that sparked this week's devastating wildfires in Spain and France and has spiked Southern Europe's burning the past eight years, two new studies conclude.

Human-caused climate change made the hot and dry conditions responsible for Spain's record-sized inferno 20 times more likely to happen, and it doubled the chances of extreme fire conditions for the flames in France, scientists at World Weather Attribution calculated in a rapid analysis Thursday, conducted while fires were still burning. Warming in the past 26 years has tripled the odds of the severe fire risk conditions in Spain and increased the chances in France 40%, the same report found.

At the same time, researchers published a separate study on Thursday — written and edited long before this week's fires began — that found the number of days that Southern Europe's weather reached extreme fire-prone levels has more than doubled compared to decades ago.

Both studies examined changes in the weather that creates fire-prone conditions. The measurements factor in air temperature, drought conditions, humidity and wind.

Ancient mummy DNA provides scientific evidence that colonization brought smallpox to the Americas

NEW YORK (AP) — Ancient mummy DNA recovered in Chile has yielded the firmest evidence yet that European colonization brought smallpox to the Americas.

Smallpox was one of the deadliest diseases in human history before it was eradicated in 1980, largely thanks to vaccination. For centuries, the virus had killed about one-third of the people it infected and left most survivors with deep and sometimes disfiguring scars.

Outbreaks struck Asia and Europe and eventually spread to the Americas, where colonial writings, administrative records and missionary reports documented how it killed millions and devastated Indigenous populations who had never been exposed to the virus.

Now there's scientific evidence for the spread: An analysis of Chilean mummies provides the strongest genetic link yet to the virus as it existed outside of the Americas, and provides a better picture of how it reached remote populations through colonization, said geneticist Shigeki Nakagome with Trinity College Dublin.

Poll suggests some Liberal supporters concerned about climate policy are leaning NDP

OTTAWA - A new online poll from the Angus Reid Institute suggests that one in six 2025 Liberal voters now say they would support the NDP.

The pollster found that half of these voters cite climate change as the issue that concerns them most. The poll also found that these voters are three times more likely to be concerned about inequality, with 34 per cent of red-orange switchers listing it as a priority compared to 10 per cent who are staying in the Liberal tent.

Angus Reid reports that 21 per cent of respondents nationally say that climate change is a top concern, an increase from the 14 per cent recorded just four months ago. The pollster said that wildfire season is a "stark reminder" of the threat climate change poses in a write up of its findings.

NDP Leader Avi Lewis told The Canadian Press Tuesday that he's been hearing from Liberals in Montreal are now looking to support his party.

Between prices and a diarrhea-causing parasite, lettuce is causing hard times at some restaurants

It’s been a choppy year for restaurants that lean into lettuce.

Lettuce prices rose sharply in the first half of 2026 due to hot weather in Arizona, where about one-third of America’s lettuce is grown. Now, restaurants are dealing with the fallout from a cyclospora outbreak linked to shredded lettuce that has sickened thousands of Americans.

Yum Brands, the parent company of Taco Bell, said Thursday that Taco Bell's U.S. same-store sales are down 2% so far in the July-September period due to customers' concerns over the outbreak. That compares to a 7% same-store sales increase in the April-June period.

Federal health officials first tied the diarrhea-causing outbreak to shredded iceberg lettuce served at Taco Bell restaurants in Indiana, Kentucky, Michigan, Ohio and West Virginia. Later, the U.S. Food and Drug Administration said customers in Illinois, Kansas, Oklahoma and Pennsylvania were also affected.

Climate change? It’s already here

Winnipeg’s roads are buckling. Ontario forests are burning. Toronto chokes on wildfire smoke. The summer heat dome in Europe has already killed thousands. Climate change is not some future dystopian vision. It’s right here, right now. And the cause is crystal clear: burning fossil fuels.

Wreckage found of Pan Am plane crash that helped lead to today’s safety briefings on every flight

Searchers have found the wreckage from a Pan Am flight that plunged into the ocean off Puerto Rico in 1952, an accident that killed 52 and led to requirements for the passenger safety briefings given on every commercial flight.

The plane, the Clipper Endeavor, made a hard landing after losing engine power shortly after takeoff. The 17 passengers and crew who survived told investigators everyone lived through the landing, but panic set in as many passengers struggled to find life vests and the crew had a hard time pulling out life rafts.

Within minutes, the plane sank. Explorers found the wreckage of the DC-4 last month by using an autonomous sonar drone to locate the fuselage and tail in 2,000 feet of water.

Now before takeoff, flight attendants instruct passengers about exit locations and where life vests are located and how to inflate them.

Nearly one in four watercraft fail inspection during roadside blitz to prevent aquatic pests

More than 120 watercraft failed a roadside inspection over the weekend aimed at slowing the spread of aquatic invasive species, including zebra mussels.

Blueberry First Nations says native plant orchard to help restore B.C. industry sites

FORT ST. JOHN - A First Nation in British Columbia says a new native plant orchard established in its territory could help reclaim and restore thousands of industrial sites around northeastern B.C.

The Blueberry First Nations near Fort St. John unveiled the orchard last week, and Chief Sherry Dominic said it will produce native plants for sale to industry partners in the oil and gas sector, as well as Indigenous communities.

The nation says in a statement the garden will eventually have 1.7 million seedlings from a representative supply of grasses, shrubs, wildflowers and trees to reflect various layers of a healthy forest system.

"So, eventually, (the orchard) will be putting the land back to its natural form," Dominic said in an interview.

Remains of dinosaur skull found in B.C. campground belonged to T. rex ‘great-uncle’

The remains of a dinosaur skull found in British Columbia campground belonged to a tyrannosaur that was lighter and faster than its more famous relative, the T. rex, say the authors of a new study.

University of Alberta and McGill University researchers studied the cast of a partial skull impression that was left about 76 million years ago and discovered it belonged to a horned dinosaur known as Gorgosaurus.

Their findings, published in the journal Palaeogeography, Palaeoclimatology, Palaeoecology last month, give new insight into a species that once roamed what is now Western Canada, said lead author Colton Coppock from the University of Alberta.

"We were able to identify (Gorgosaurus) based on a unique set of characteristics on this impression," Coppock said.

Birds’ evolution from feathery, winged dinosaurs chronciled in riveting, well-researched account

Whenever Steve Brusatte’s preschool-aged son was asked which were his favorite dinosaurs, the precocious boy would proclaim: penguins!

He had learned well.

Now his father has extended his educating beyond his family with The Story of Birds, which traces the “long, gradual evolutionary journey” (150 million years) of birds from their origins in the Jurassic period to the over 10,000 species that exist in the world today. It’s a marvelous story.

The connection between dinosaurs and birds has been known ever since 1868, when Thomas Henry Huxley first claimed that birds were the descendants of dinosaurs. Few believed him. It was hard to imagine that wrens and robins, even eagles and vultures, were in any way related to such ancient mega-fauna as T. rex or brontosaurus.

Cut the number of choices you make each day. Your brain will thank you

Jeans that fit perfectly. The ideal Netflix show for a Tuesday night. Your one and only soulmate. Modern life promises that with enough options, you will happily find the best of everything.

But behavioral scientists say the increasing flood of choices — whether it comes to shopping, social lives or relationships — is doing the opposite.

The idea that more choice is better is baked into Western culture, but research shows that having more options can make people anxious, indecisive and, paradoxically, less happy with what they pick, said Barry Schwartz, an emeritus psychology professor at Swarthmore College and author of “The Paradox of Choice.”

“There have been hundreds of studies showing that there can be too much of a good thing,” Schwartz said.

Fire-ravaged First Nations community accuses Ottawa of denying it federal aid

OTTAWA - A small First Nations community in Ontario that was burned to the ground by a raging wildfire on Monday is being deprived of the help it needs because the federal government doesn't recognize it as a First Nation, the community's lawyer says.

And its chief says she didn't hear anything from Indigenous Services Minister Mandy Gull-Masty for nearly a week after the fire broke out.

Residents of Collins First Nation, a remote community without road access more than 200 kilometres north of Thunder Bay, were forced to self-evacuate earlier this week in advance of fast-moving fires.

Videos show community members fleeing on small boats as the flames encroached upon the shoreline.

Lettuce at Taco Bell in 5 states confirmed as a source of diarrhea-causing parasite

ATLANTA (AP) — Federal health officials have identified lettuce from Mexico served at Taco Bell locations across five U.S. states as a source of a widespread outbreak of diarrhea-causing parasite cyclospora.

The Centers for Disease Control and Prevention late Thursday warned consumers not to eat shredded iceberg lettuce from Taco Bell restaurants in Indiana, Kentucky, Michigan, Ohio and West Virginia. A record number of cyclospora cases have been reported in more than 30 states, and experts have said not every recent U.S. illness might be caused by a single source.

A Food and Drug Administration investigation so far has identified a single supplier of the lettuce. The federal warnings to consumers did not identify the company, but Taylor Fresh Foods, of Salinas, California, said FDA testing indicated it was “a specific independent farm” affiliated with the company.

The FDA was working with the supplier “to determine if potentially contaminated shredded iceberg lettuce remains on the market,” including in other states, the CDC said. “Taco Bell has committed to stop using any lettuce from the supplier identified by FDA’s traceback investigation.”

SpaceX Starship launch aborted on the pad at the last moment

SpaceX’s mega Starship rocket came within a second or so from blasting off on a test flight Thursday, but some of the engines failed to ignite, triggering a launch abort amid billowing clouds of smoke and vapor.

Elon Musk, the company's founder and CEO, said two engines will be replaced “to be confident of a good flight” before sending Starship from Texas on a space-skimming journey halfway around the world. It will be the 13th flight for Starship, which at 407 feet (124 meters) tall with 33 main engines is the world’s biggest and most powerful rocket.

SpaceX's launch webcast showed the start of engine ignition three seconds before the planned liftoff, viewed from a drone high above the pad. Although the company did not elaborate, onscreen data showed four engines not firing, with the remaining 29 engines immediately shutting down and keeping the rocket anchored to the pad. It was the first time a full-scale Starship experienced a last-second abort like this.

The launch team immediately began draining the fuel from the rocket.

Manitoba documentary focuses lens on environmental defenders, beauty of prairies

Everything We Need Is Here is the latest sumptuously shot Manitoba film rooted in the Prairie landscape.

Though totally unrelated in subject matter, the documentary recalls the 2024 Daughters of the Sun with its saturated and slow-mo sweeps across boreal forests and limestone tinted lakes.

But while Daughters has much murmured narration and arthouse flair, Everything is a plucky film, a can-do sort of doc about the land and its grassroots defenders.

Their voices resonate strong and clear across storylines that weave together the joys of foraging and local environmental protests.

Hegseth announces new policy to test troops for low testosterone

WASHINGTON (AP) — Defense Secretary Pete Hegseth announced Wednesday that he is rolling out a new screening program for “testosterone deficiency” among troops, calling it necessary to allow them to operate at their "absolute best.”

The screenings will be conducted annually as part of service members' required medical screenings for those 30 and older, he said. Troops under 30 can volunteer to be tested. In a video on social media, Hegseth said receiving testosterone replacement therapy would be voluntary.

In the video, Hegseth simply refers to troops, though it appears he is talking about only testing men in uniform for hormone irregularities.

The move comes as other Trump administration officials have begun to advocate for men to have easier access to testosterone replacement therapies, but the messaging from Hegseth and others blends known science on the hormone with broader, and less substantiated, claims.

Buckled concrete gives drivers the heave-ho

Highways, local roads and sidewalks have buckled and broken thanks to extreme heat in recent days, wreaking havoc with travel.

Garth Thomson was driving on the Perimeter Highway, just north of Assiniboia Downs, around 4 p.m. Sunday when he suddenly came upon a major gap in the road.

“There was a big break in the highway, which was the heaving. I had about four seconds to decide what I was going to do. So, I kind of hit my brakes and drove more towards the centre, where the big chunks weren’t (located),” said Thomson. “It happened so fast … there were big chunks (of concrete), probably a foot (per) square, sticking up.”

His convertible had bumper damage and a hole in its gas tank, he said.

Federal researchers using driftwood to study and track seabird deaths off N.S. coast

HALIFAX - Federal researchers want to know where dead seabirds off the coast of Nova Scotia are most likely to wash up, and they’re using a low-tech solution to find out: driftwood.

Environment and Climate Change Canada has dropped about 600 wooden blocks in the ocean this summer. Coated in non-toxic, bright orange paint and affixed with contact information, the floating blocks are essentially standing in for bird carcasses.

Researchers are hoping birders and beachcombers who find them will report their date and location, ultimately helping to create a picture of where seabirds might drift after a mass death in the ocean.

“So you release these blocks and they help you figure out where carcasses could drift and what proportion of the carcasses end up on shore," Rob Ronconi, a biologist and wildlife emergency response coordinator for the federal environment department, said in an interview.

Chief says assembly will tackle effect of major projects push on First Nations rights

OTTAWA - Major projects and a coming meeting with Prime Minister Mark Carney and the premiers will be the main focus of the Assembly of First Nations annual general assembly this week, National Chief Cindy Woodhouse Nepinak said Monday.

The AFN gathering begins Tuesday and runs for three days.

Speaking alongside a handful of regional chiefs and First Nations representatives at a news conference, Woodhouse Nepinak blasted the federal government over its approach to major projects development and said it could threaten the rights of First Nations.

She said First Nations are not opposed to economic growth and are simply asking for a seat at the table as the federal government attempts to shore up the economy.

In a sweet discovery, astronomers find sugar lurking in the space between stars

NEW YORK (AP) — The space between stars just got a little sweeter.

Astronomers have detected a type of sugar in space that's also found in raspberries and self-tanners. The sugar, called erythrulose, lurks in what's called the interstellar medium: thin clouds of gas and dust littered between stars.

Sugar does more than sweeten tea and powder doughnuts. Different varieties fuel our cells and even make up DNA. Scientists are itching to know how sugars form because they're a key ingredient for life as we know it.

Using two dish-shaped radio telescopes in Spain, researchers collected data from a large gas cloud near the center of the Milky Way. They identified the sugar in gas form by comparing telescope signals to samples in the lab. It's the latest kind of sugar detected in space — in a region crossed by NASA's twin Voyager, the farthest spacecraft to ever travel from Earth.

If it works in Ontario, why not in Manitoba?

Grid-scale battery storage has fundamentally changed the global energy landscape — and Manitoba needs to get on board.

Battery systems store large amounts of excess electricity for when it’s most needed. While they can be charged from any generation source, they are especially beneficial for integrating wind and solar power, which vary with weather and time of day. Batteries allow electrical grids to meet the need for firm, dispatchable and affordable capacity using renewable energy, rather than relying on coal, nuclear and fossil gas. They also provide numerous other benefits, including reducing overloading of transmission infrastructure and helping to regulate the grid’s frequency and voltage.

Average costs for grid-scale batteries plummeted by more than half between 2023 and 2025 and installations have skyrocketed in China, the U.S., Australia and Europe. Texas now has 16,500 megawatts (MW) of battery storage, while California has 15,200 MW. Closer to home, Ontario recently awarded 640 MW of contracts to three battery storage projects in a competitive auction, with batteries beating out fossil gas-fired power plants on cost every time. One of these projects will be built near Dryden, only four hours east of Winnipeg.

Each battery system will provide eight hours of capacity but will cost considerably less than Ontario’s previous battery procurements, which provide only four hours of capacity. With this latest auction, Ontario has now secured 3,600 MW of battery storage capacity, including the operational Oneida (250 MW), Hagersville (300 MW) and Napanee (250 MW) projects. Almost all have significant Indigenous participation, with the latest procurements boasting 50 per cent First Nations ownership.

Tanmaxxing trend leaving gen Z cooked

Tanning isn’t new and, like every beauty norm, has seasons where it’s in and seasons where it’s out. But unlike their bronzed forebears, gen-Z tanfluencers know the risks of sun exposure.
