Changes to Canada’s climate now ‘irreversible,’ federal report says

OTTAWA - The impacts of climate change in Canada are now largely irreversible and average temperatures are expected to rise by at least 3.5 C by the end of the century, a new government report warns.

The report, published Thursday, is the second released by Environment and Climate Change Canada examining changes to Canada's climate. It was authored by nearly two dozen government and climate science experts.

It says that even if the world reaches net-zero emissions by 2075 — which would mean any greenhouse gases would be captured by nature or technology — the effects in Canada will be stark.

The report says those effects include a nearly 50 per cent increase in the area burned by wildfires and glaciers in Western Canada losing more than 75 per cent of their mass.

Scientists studying cockroach milk and nose-blowing win Ig Nobel prizes for quirky science

Ten research teams were honored Thursday at a satirical science awards ceremony that was hosted outside the U.S. for the first time due to travel concerns.

Researchers who studied milk from cockroaches and analyzed soil health using underwear received Ig Nobel prizes celebrating unusual and imaginative contributions to science.

The awards organized by a digital magazine called the Annals of Improbable Research shifted to Europe after 35 years in the United States over concerns about attendees being able to get visas.

At a convention center in Zurich, Switzerland, research teams received a custom trophy resembling a cross between a mushroom and a human foot. Among them were Matilda Brindle and Stuart West from the University of Oxford and the Florida Institute of Technology's Catherine F. Talbot, who reconstructed the evolutionary history of kissing, and the late Dr. Tokuji Unno who investigated the science of blowing one's nose.

Japanese scientist Shirakawa, co-winner of 2000 Nobel Prize in chemistry, dies at 90

TOKYO (AP) — Japanese scientist Hideki Shirakawa, co-winner of the 2000 Nobel Prize in chemistry for discovering and developing conductive polymers, has died. He was 90.

The discovery by Shirakawa and two fellow American scientists, Alan Heeger and Alan MacDiarmid, demonstrated that plastic could conduct electricity like metal and be used in applications such as electronics.

Shirakawa died on Aug. 24, according to the University of Tsukuba, where he taught and researched after joining in 1979. The university did not specify a cause of death. Japan's largest newspaper, the Yomiuri, said Shirakawa died at a hospital in Yokohama, west of Tokyo.

Born in Tokyo in 1936, Shirakawa earned a doctoral degree in engineering at the Tokyo Institute of Technology in 1966. Ten years later, he became a researcher at the University of Pennsylvania, where he worked with McDiarmid and Heeger.

Recognizing the value of phys-ed for kids

The message from Premier Wab Kinew and Education Minister Tracy Schmidt last week about the importance of exercise for young people was timely and important — but it is not new.

Rare and tough to notice, sarcomas may lurk in the body

Last summer, Michelle Finley was going about a normal day.

She had just dropped her car off at a garage and was walking back to her office building downtown when, suddenly, she was stopped in her tracks by a searing cramp on the bottom of her right foot.

“It was so painful it took my breath away,” says Finley, now 52. “I stopped and held on to the side of a building for a second — like, it was bringing tears to my eyes.”

Finley thought she had a really bad case of plantar fasciitis. Nine months later she would lose her foot to sarcoma.

Beware invasive, ‘frightening’ waterhemp

There’s a threat lurking on the edge of Manitoba farmers’ fields this fall that’s even scarier than the escalating trade war with their biggest customer.

Provincial extension advisers are warning farmers to watch for a weed known as “tall waterhemp,” which, true to its name, may already be towering above ready-to-harvest crops.

Those wispy tentacles waving in the breeze look pretty innocuous from a distance. But this highly invasive member of the pigweed family produces hundreds of thousands of seeds that are just itching for dispersal through farmers’ combines and across their fields.

Each of those tiny seeds — one small pill container filled halfway holds 44,000 — can produce plants with stems the width of saplings and heights of two to five metres. One or two plants can quickly turn into a patch. If waterhemp takes over a field, it can choke out the growing crop and cut yields by more than 90 per cent.

U of M research role expands after $79-M federal injection

The University of Manitoba is playing in a new league.

A $79-million investment will bring five internationally recruited researchers to Manitoba to build “ambitious,” long-term research programs in areas of strategic national importance.

The five researchers will join the U of M thanks to the federal government’s $1.7-billion research talent initiative that’s designed to help Canadian universities compete globally for leading researchers.

The initiative’s flagship program, the Eddie Goldenberg Research Chairs of Canada, provides universities with the funding and resources to recruit world-class researchers, build research teams and pursue large-scale projects in fields considered important to Canada — from Arctic navigation and defence to sustainable mining, health equity and environmental law.

Entrepreneur Willow Wolfe conceived and crafted a better — and cruelty-free — paint brush

NAROL — Talk about a brush with fame.

Fifteen years ago, Willow Wolfe, the founder of Willow Wolfe Painting Courses and Art Supplies, read about American actor/artist Richard Grieco’s experimentations with a style of painting he’d coined as “abstract emotionalism.”

Wolfe, whose personally designed line of synthetic paint brushes and watercolour workbooks are sold at more than 450 retailers around the globe, mailed Grieco (21 Jump Street, Veronica Mars) a set of brushes she felt would suit his needs.

The two have since remained in touch and this spring Grieco contacted Wolfe again, to let her know about a semi-autobiographical movie called The Painter he was directing and starring in.

United Nations talks in Mongolia expose growing drought crisis as climate impacts worsen

BENGALURU, India (AP) — Representatives from nearly 200 countries wrapped up United Nations desertification talks in Ulaanbaatar, Mongolia on Friday, seeking ways to keep land productive as climate change heats the planet and degraded soils and landscapes lose their ability to hold water, produce food and support livelihoods.

Up to 40% of the world’s land is degraded, according to the United Nations Convention to Combat Desertification, which organizes the biennial talks. Droughts are also emerging in areas that were not considered highly vulnerable a decade ago, said Yasmine Fouad, the convention’s executive secretary.

“Drought is coming coupled with the impact of climate change,” Fouad said in an interview with the Associated Press. “It’s becoming more frequent, more intense and more prolonged."

Countries left Ulaanbaatar without resolving one of the talks' key issues — whether to create a legally binding global drought agreement — postponing a decision until the next round of talks in Egypt in two years. The issue had already been deferred at the previous meeting two years ago.

Wasp attack warnings as swarms surge in B.C. amid warm weather and abundant food

VANCOUVER - When the wasp swarm attacked a climber on a trail north of Vancouver this week, her reaction was so severe she needed helicopter evacuation.

But Maria Masiar, search manager with Lions Bay Search and Rescue, said the wasps weren't done, attacking rescuers, and then another group of hikers who were sent scrambling by the same stinging swarm when they came across the scene.

Pest control expert Mat Neale said he had seen a "dramatic increase" of wasp calls in British Columbia, as warm weather and abundant food contributed to a late summer surge in numbers of the stinging insects.

Backcountry and rescue groups have been warning against the unusual number of wasps on popular trails.

Researchers tracking Manitoba monarchs migrating to Mexico

Thirty monarch butterflies were outfitted with trackers at the Living Prairie Museum this week as part of a national effort to help preserve the endangered species, marking the first time the new technology has been used in Manitoba.

How to reset your child’s sleep schedule for back-to-school season

NEW YORK (AP) — After a summer of vacations and late nights, it's time to set those back-to-school alarms.

A good night’s sleep helps students stay focused and attentive in class. Experts say it's worth easing kids back into a routine with the start of a new school year.

“We don't say ‘ get good sleep ’ just because,” said pediatrician Dr. Gabrina Dixon with Children's National Hospital. “It really helps kids learn and it helps them function throughout the day.”

The amount of sleep kids need changes as they age. Preschoolers should get up to 13 hours of sleep. Tweens need between nine and 12 hours. Teenagers do best with eight to 10 hours of shut-eye.

Earth is simmering in its hottest water temps on record, and that’s bad for fish and us

The world's oceans simmered to their hottest temperatures on record over the weekend and are likely to warm even further in the next few months, putting stress on life in the water and on land too, the European climate service Copernicus announced Monday.

Spurred by a still growing but already supersized natural El Nino and human-caused climate change, the world's ocean temperatures hit 21.1 degrees Celsius (70 degrees Fahrenheit) on Friday and Saturday, narrowly edging out the average daily record set in March 2024, said Samantha Burgess, strategic climate lead for Copernicus.

“This is yet another sign of our climate system under strain and the ocean under immense pressure,” Burgess said.

Jane Lubchenco, an oceanographer and former chief of the U.S. National Oceanic and Atmospheric Administration called the record “very troubling.”

Pretty, purple and pernicious plants plaguing Prairies

After noticing mysterious purple flowers popping up in little patches around the Wolseley neighbourhood last summer, Vic Penner didn’t give it too much thought.

However, this summer, the deceivingly beautiful flowers were impossible to ignore.

“They were just everywhere,” said Penner, 37.

Wolseley isn’t the only neighbourhood being overrun by the plant.

Mobility tests can tell doctors a lot about how you’re aging, but there are many other factors

Hand grip strength. Balance tests. Standing up from a seated position on the floor. These physical challenges are often touted as measurements of healthy aging and even predictors of longevity.

They can provide valuable indications of your stamina and strength. They can estimate the risk of falls, which increase older adults ' risk of death. And they're useful to doctors who work to address aging or people with injuries.

But they're no crystal ball.

“A poor or declining result is a reason for a health professional to investigate why function is changing, rather than gauging how long someone will live,” said Auriel Willette, an expert on brain aging at Rutgers University.

Federal officials announce water cuts as Colorado River supplies continue to plunge

Federal officials announced sharp water cuts for the next two years on Friday for three Western states that rely on the imperiled Colorado River.

Under the Bureau of Reclamation's plan, California, Nevada and Arizona will collectively reduce water use by 1.25 million acre-feet (about 1.54 billion cubic meters) annually during that period, with the possibility of larger cuts depending on conditions.

Arizona will see the biggest cuts, while states upstream — Colorado, Utah, Wyoming and New Mexico — do not face any for now.

Meanwhile neighboring Mexico will reduce its intake by 250,000 acre-feet (about 310 million cubic meters) under a U.S.-Mexico treaty.

Wolseley residents put down roots to save elms

A neighbourhood group that raised thousands of dollars to inoculate publicly owned trees against Dutch elm disease hopes others will follow their lead.

Mole Mobile on move for your dermatological needs

This weekend, the Mole Mobile will set up shop at three Winnipeg Walmart locations. The mobile clinic will have certified dermatologists on site to screen suspicious-looking moles or lesions for skin cancer.

Before-and-after NASA images show crater carved by a SpaceX rocket that slammed into the moon

CAPE CANAVERAL, Fla. (AP) — A NASA spacecraft circling the moon is providing the sharpest views yet of the crater carved by a crashing SpaceX rocket.

The space agency released before-and-after photos of the impact area on Tuesday.

The Falcon rocket’s upper stage plowed into the moon at 5,400 mph (8,700 kph) on Aug. 5 after drifting through space for more than a year. It launched a pair of private moon landers with experiments and even a tiny rover in 2025 as part of NASA’s push to commercialize lunar exploration.

Based on these new photos by NASA’s Lunar Reconnaissance Orbiter, the fresh crater appears to be 60 feet (18 meters) across and less than 10 feet (3 meters) deep, according to scientists.

Trump administration moves ahead to end roadless rule on national forests

ALBUQUERQUE, N.M. (AP) — The Trump administration announced Tuesday it is moving ahead with plans to rescind a quarter-century-old rule that blocked logging, road building and other development on national forest lands, drawing the ire of environmentalists nationwide.

The U.S. Forest Service is filing a proposal that would scrap the so called roadless rule adopted in the last days of Bill Clinton’s presidency in 2001. The agency described the rule as a one-size-fits-all restriction that has frustrated land managers and served as a barrier to reducing wildfire risks in the nation’s forests.

“Our forests can’t afford another decade of inaction. Across the country, we’ve watched preventable conditions — overgrown stands, insect outbreaks and disease — turn healthy landscapes into tinderboxes,” U.S. Agriculture Secretary Brooke Rollins said in a statement.

Scientists say that worsening wildfires are driven by a combination of climate change that warms and dries out forests, less logging and decades of fire suppression that has allowed fuels to build up.

A grand jeté of climate-change denial

The first hurricane to hit Hawaii in 34 years. The Mediterranean on fire from Spain to Greece. ‘Heat domes’ one after another for months on end in Europe and North America. Thousands of excess deaths. A record El Niño piled on top of an average global temperature up from +1.2 C five years ago. Predicted high for this year: +1.7 C.

Surely they’ll get it now, you think — but no, they won’t. It once seemed sensible to think that when the climate damage gets bad enough and the trend line becomes impossible to ignore, ‘they’ (meaning the climate change deniers and their fellow travellers) will finally accept that the threat is real and urgent action is necessary.

A few of them will, but most will not.

It is becoming clear that as the old position of flat disbelief in climate science becomes untenable, the preferred response among former deniers is to admit that climate change is big, dangerous and already well underway — but to insist that it is already too late and nothing can be done about it now.

U of M exhibition brings ancient Roman Egyptian documents to life

Two thousand years ago, people in Roman Egypt wrote letters, kept receipts, made lists and dealt with the everyday bureaucracy of life. Some of those pieces of ancient life are now on display in Winnipeg.

Inside the Montreal lab working to prepare Canada against future pandemics

MONTREAL - In a biomedicine laboratory at Polytechnique Montréal, animal protein grows in a bubbling orange solution as researchers in white lab coats take samples with large syringes.

Neatly-labelled glass bottles filled with clear liquid line the shelves next to computer monitors, where the scientists examine the antibodies produced by the cells.

In a room down the hall, a large cryogenic freezer is filled with tubes containing samples of proteins and cells that can be used to develop vaccines and medicines.

Six years after the spread of COVID-19 caught the world by surprise, the Polytechnique lab is spearheading efforts to prepare Canada against future pandemics.
