Researchers put hail under microscope, take stock of June 9 storm

Jack Hamilton, a researcher with the Canadian Severe Storms Laboratory, and his team have been gathering evidence and data from the June 9 storm that brought record rainfall to Winnipeg and surrounding communities

Growing number of Manitoba youths are addicted to vaping

A few minutes after the final classes of the day end at Grant Park High School on a recent afternoon, students stream out of the building, headed in myriad directions.

At the railing outside the front doors, several teens stop to vape.

Classmates and teachers walk past without a second glance. Behaviour that once might have raised eyebrows now barely registers.

For many Manitoba teens, vaping — using a battery-powered device to heat flavoured “juice,” most often containing highly addictive nicotine, into an inhalable vapour — is a habit deeply woven into their daily lives.

Montana DEQ works toward impairment designation for Big Hole River

The Big Hole River, a blue-ribbon fishery that’s become a focal point in a years-long debate over nuisance algae growth, is poised to receive an impairment designation.

At an open-house meeting in Divide on Tuesday, the Montana Department of Environmental Quality announced that the Big Hole, a mellow freestone river critical to southwest Montana’s outdoor recreation and agriculture economies, is struggling as a result of ecologically detrimental nutrient loading.

The term DEQ is using in its discussion of the Big Hole is eutrophication, which describes the link between algae growth and excess nutrients such as nitrogen and phosphorus. When there’s too much algae in a river or lake, dissolved oxygen falls, imperiling fish and the aquatic life they feed on.

Algal growth is also unpopular with members of the recreating public because it can make wade-fishing a slipperier — and therefore more perilous — endeavor. And it drives down biodiversity in the macroinvertebrate population, which has repercussions for fish and other species higher up the aquatic food web. Andy Ulven, who leads DEQ’s water quality division, told Montana Free Press on Tuesday that a eutrophication listing would “formalize that there is an issue on the mainstem” of the Big Hole. He added that the agency proposal is still in draft stage and he doesn’t anticipate a final designation for the Big Hole until 2027 at the earliest.

What to know about earthquake early warning systems

As earthquakes struck from California to Venezuela to Japan, millions of people received warnings on their mobile phones, providing critical seconds to seek protection.

Venezuela was struck with a pair of deadly earthquakes Wednesday evening and Thursday morning that brought significant shaking to the northern coast of Japan. Earlier in the week residents in the U.S. state of California experienced a moderate earthquake, and at the start of June, 37 people in the Philippines died in a quake near Mindanao.

Many nations have developed systems for alerting people seconds before shaking begins. Even in countries like Venezuela that do not have such systems, Google Android Earthquake Alerts can send warnings.

B.C. government marks 5 years since heat dome killed hundreds

VANCOUVER - A stifling heat dome that sat over much of British Columbia five years ago is being remembered by the provincial health officer as traumatic for people who lost loved ones and overwhelming for those trying to care for those affected. 

More than 600 people died during the first provincewide heat dome in 2021, but Dr. Bonnie Henry says it will not be the last such event. 

Henry says in a statement issued Thursday that most of the people who died during the period between June 25 and July 1 lived alone and weren't able to keep cool inside their homes. 

She says her thoughts are with those who live with trauma from the event and she knows of the "tremendous effect" on people who lost loved ones and on the first responders and health-care workers who were overwhelmed with people needing help. 

The 2 earthquakes that struck Venezuela are known as a ‘doublet.’ Here’s how they happen

SAN JUAN, Puerto Rico (AP) — The two powerful earthquakes that struck Venezuela’s northern coast, killing more than 180 people, were an event known as a “doublet.”

Doublet earthquakes happen when a pair of similar-sized quakes hit close in location and time, according to the U.S. Geological Survey. On Wednesday evening, a 7.2 magnitude quake hit first, followed by a magnitude 7.5 just 39 seconds later.

The deadly one-two punch toppled buildings in Venezuela’s capital, Caracas and beyond. Some 1,500 people were injured and thousands were reported missing. The coastal region of La Guaira, which is north of Caracas, experienced some of the heaviest damage and casualties, officials said.

How rare are doublets?

Get a load of this: Humans and great apes share similar giggles

Humans and great apes have been giggling in similar ways since branching off the evolutionary tree, a new study suggests. How do we know this? Researchers tickled 13 captive apes — including gorillas, orangutans, chimpanzees and bonobos — and recorded the results.

Grade 7 students learn about environment in Seine River cleanup

On a rainy Wednesday morning, Grade 7 students from École Lacerte traded their classroom desks for rubber boots as they headed out along the Seine River to help plant native shrubs, test water quality, and clean up the riverbank.

JJ Swidersky, one of about 40 students taking part in the work, says protecting the environment is important to him and his classmates.

“Planting the trees, planting the shrubs,” Swidersky said when asked about his favourite part of the effort. “Just trying to keep the river clean, trying to keep it as clean as we possibly can.”

The planting Swidersky is referring to is part of the Niakwa Trail Rain Garden, which is located next to the St. Anne’s Superstore.

Health Canada approves weight-loss drug for sleep apnea in patients with obesity

TORONTO - Health Canada has approved weight-loss drug Zepbound for treating obstructive sleep apnea in adults with obesity.

The department confirmed that the authorization granted on June 11 makes Zepbound the only GLP-1 drug in Canada approved for the sleep disorder that causes people to stop breathing temporarily because their upper airway is blocked.

That blockage can happen when throat muscles relax or when there is too much fatty tissue around the upper airway.

Sleep apnea causes daytime sleepiness and other potential risks including high blood pressure, heart attacks and strokes, said Dr. Mandeep Singh, a clinician investigator in sleep science at University Health Network in Toronto.

When a rip current sucks you out to sea, try not to panic

SAN DIEGO (AP) — To someone who is getting sucked out to sea by a rip current, “Don’t panic!” may be difficult to heed, even if that’s exactly what you should do. But lifeguards say to not only relax but flip over and float out of the danger.

Rip currents are one of the coast’s greatest dangers and account for the most beach rescues every year. About 100 people drown from rip currents along U.S. beaches each year, according to the United States Lifesaving Association. And more than 80% of beach rescues annually involve rip currents.

Already this year, there have been at least 21 people killed from rip currents in U.S. waters, according to the National Weather Service.

Here are some things to know about rip currents:

Depave paradise, tear up a parking lot

Concrete is ubiquitous “wonder” material called concrete, celebrated by architects and city planners everywhere because it’s cheap, strong and so malleable it’s capable of taking almost any shape. But like all purported wonder materials, it can be hugely destructive when used in vast quantities.

A Serbian town is known for raspberries that are exported around the world

ARILJE, Serbia (AP) — Serbia 's town of Arilje is known as the Balkan country's “raspberry capital,” with its fame reaching beyond borders.

Arilje and its surroundings yield berries that are exported as far as the United States and Japan. Serbia is among the top three exporters of raspberries globally.

“We are born, we live and we die with raspberries,” said Mileta Pilcevic, who heads a local association of raspberry producers. “Arilje is unique in the world. You can’t find a smaller place with such big concentration of raspberry production.”

The hilly landscape has ideal climate for raspberry cultivation. The berries from Arilje are grown without chemicals and picked by hand for high quality.

Archaeologists find huge Viking textile production site in Denmark

SØFTEN, Denmark (AP) — Archaeologists have discovered a huge Viking Age textile production site in Denmark that dates back more than 1,000 years and underlines the sophistication of Viking society.

Experts from the Moesgaard Museum said this week that the sprawling 100,000-square-meter (more than 1 million-square-foot) site features an area for processing flax as well as more than 80 pit houses — semi-buried huts that were used as workshops and dwellings in Viking times.

It's located in Søften, 10 kilometers (6 miles) north of Denmark’s second-largest city, Aarhus, on the Jutland peninsula. The site dates back to the late Iron Age and early Viking Age, sometime between A.D. 600 and 950.

Archaeologist Liv Stidsing Reher-Langberg, who led the 10-month dig, said that “we have a clear focus on textile production, which makes this settlement different from other kinds of settlements of this period.”

In a visit to Capitol, Jessie Diggins and other Olympians push for climate change solutions

Olympian Jessie Diggins visited Capitol Hill with her four medals in hand Wednesday to advocate for clean air, clean water and a healthy planet.

America’s most decorated cross-country skier is part of “Protect Our Winters,” an athlete-driven environmental group that sent a coalition to Washington to meet with lawmakers Tuesday and Wednesday. The group is most concerned with how the Environmental Protection Agency has weakened key climate, water and pollution regulations since President Donald Trump returned to office.

“I don’t want to stick my head in the sand and ignore the world burning,” Diggins said in an interview. “I feel like I have a responsibility to use my voice to advocate for change. And so that’s why it’s so important to me, because I want my great-grandkids to be able to build a snowman and try cross-country skiing someday, and be able go hiking and fishing and camping in the summer, and breathe clean air. I want that for them very badly.”

Diggins retired from professional ski racing this year after earning bronze in the women’s 10‑kilometer interval start at the 2026 Milan Cortina Winter Olympics. Many skiers expressed concern during these Olympic Games about climate change and the accelerating melt of the world’s glaciers. A warming world jeopardizes the future of their sport.

COVID-19 vaccine study that was blocked from CDC journal is published elsewhere

NEW YORK (AP) — A study on COVID-19 vaccine effectiveness has finally been published after being blocked from a government health journal.

The vaccine was found to be about 55% effective against COVID-19-associated hospitalizations, and reduced COVID-19-related trips to emergency departments and urgent care clinics by 50%, according to the study published Tuesday by JAMA Network Open.

The findings are not particularly surprising: Researchers have repeatedly found that COVID-19 vaccines work. But the paper drew public attention after Trump administration political appointees decided not to run it in a Centers for Disease Control and Prevention publication.

They argued that the study's design was too vulnerable to false assumptions that could produce flawed results. But many public health researchers maintain it's a reliable design that's been used for decades and offers the best way to understand how well a vaccine is working currently.

Wanted: The Teton Range’s few remaining mountain goats

Every now and then, a hiker, climber or biologist lays eyes on a mountain goat in the nooks and crannies of the mighty Teton Range.

There’s a good likelihood that the unwanted, nonnative animal doesn’t survive long after the authorities pinpoint its presence. That’s because the National Park Service is now removing all mountain goats that survived an intensive three-year effort to rid the Tetons of the species.

A striking white alpine species, mountain goats are being targeted by gunners because they’re seen as a threat to native bighorn sheep. Mountain goats are more aggressive, overlap habitat and can also spread diseases that can be catastrophic.

“We have seen mountain goats — and we have removed those when we have found them,” Grand Teton National Park Superintendent Chip Jenkins told WyoFile in February. “We hire a private contractor who does the flying in terms of doing the survey, and we hire a private contractor who does the removal.”

How a heat dome is formed and why experts blame one for Europe’s baking temperatures

Europe is sizzling under an early heat wave this week, with millions of people experiencing extremely high temperatures, and experts say a phenomenon known as a heat dome is to blame. Here's what to know.

A soothing cup of herbal tea can begin in your garden

Drink a fragrant cup of herbal tea, and the intoxicating scent of steeped herbs might calm your mind before you even take a sip. Even better is when they come from your own backyard herb garden.

Mine includes several ingredients for my daily cup, and they’re all easy to grow and prepare.

Herbal teas are distinct from true teas — such as black or green — which comes from the leaves of the Camellia sinensis plant. (You can grow that in your garden, too.) Brew herbal teas with either freshly harvested or dried herbs.

Either way, settling in with a cup of homegrown herbal tea — hot or iced — can be a relaxing ritual.

AI companies should release environmental impact, commit to clean energy, says UN chief

United Nations Secretary-General António Guterres on Tuesday called on artificial intelligence companies to release information about the carbon pollution they create, along with the water and land used to power their operations.

While urging action in an address at London Climate Action Week, Guterres proposed the AI Environmental Transparency Initiative, arguing AI companies should measure and disclose the impact of their increasingly in-demand technology — impact which has been cited by opponents as reasons to curb the rapid growth of data centers. These companies have faced mounting pressure, both from governments and locally in areas with data centers that support AI, for increased transparency and more standardized reporting across the industry.

Guterres said AI companies should also commit to powering their facilities with electricity produced with renewable technologies, such as wind and solar, by 2030.

“No more hidden costs,” Guterres said at Europe’s largest independent climate conference. “No more shifting the burden onto those least able to bear it. It is time to come clean.”

Not just a blip in the news cycle

It wasn’t, as is said, “a good look.”

When the U.K. tabloid newspaper the Daily Mail published a report on its website last week that the U.S. Centers for Disease Control and Prevention had issued a travel advisory for visitors to Manitoba, warning of a hepatitis A outbreak, there were likely audible groans in several Winnipeg offices.

The dailymail.com website gets over 35 million unique monthly visitors in the U.S. alone, making it one of the most popular news sites in the world.

So, when America’s leading public health agency issued a notice telling people to be mindful of their interpersonal interactions in Manitoba and to be vaccinated against hepatitis A before visiting, officials with tourism agencies and government ministries knew they had a job to do.

Confronting the scourge of polio

From 1928 to 1953, polio epidemics occurred in Manitoba every three to five years. The pain for the young victims was often excruciating. The vast majority of children recovered, yet many experienced lifelong disabilities from the disease.

Close encounters of the amphibian kind

Frogs, snakes and horses, oh my!

Liam Peterson, an 11-year-old outdoor enthusiast, encountered all of those during summer camp last year at Circle Square Ranch.

“There were always frogs hopping around our cabin, and I let one in because I wanted it to have company because it was bored — it was just sitting there,” recalled Liam.

“And then my friend freaked out because it was on top of (his foot) in the morning. Everyone in the cabin woke up and he woke up with a red bump on his head after hitting his head on his bunk.”
