Prolonged drought stunts the renowned wild blueberry crop in the Maritimes

HALIFAX - This summer’s prolonged drought across Atlantic Canada has had a costly impact on wild blueberry growers in New Brunswick and Nova Scotia.

Donald Arseneault, general manager of the NB Blueberries industry group, says that as this year’s harvest was wrapping up, the total yield was believed to be 70 per cent less than the previous three-year average.

“This year has been tremendously dry and we haven't really seen this in a long time,” Arseneault said, adding that this year’s crop amounted to about 20 million pounds, down from the annual average of 68 million pounds.

The industry, which ships its product around the world, was also hurt by delays caused by the provincial government’s decision to temporarily shut down the harvest as it tried to deal with a growing number of wildfires that flared up amid tinder-dry conditions.

Chinese landscape architect Yu Kongjian among 4 killed in a plane crash in Brazil

RIO DE JANEIRO (AP) — The crash of a small plane in southwestern Brazil killed four people including Chinese landscape architect and urban planner Yu Kongjian, Brazilian authorities said Wednesday.

The accident happened late Tuesday during a landing attempt at a large farm about 100 kilometers (60 miles) from the municipality of Aquidauana in Mato Grosso do Sul state, firefighters said.

Yu, who was known for promoting ecologically sound development, was traveling with two Brazilian documentary makers, Luiz Fernando Feres da Cunha Ferraz and Rubens Crispim Jr., who were making a film about the Pantanal wetlands. All three were killed along with pilot Marcelo Pereira de Barros, authorities said.

Yu was know for developing the concept of “ sponge cities, ” with infrastructure that can absorb rainwater to mitigate flood risks and improve the urban climate.

Only moratorium can save moose population: MWF

The Manitoba Wildlife Federation is calling for a moose-hunt moratorium in two parts of the province after aerial surveys showed “significantly declining” numbers of the animal.

“The populations may never bounce back,” the federation’s Chris Heald said Tuesday.

The advocacy group representing sport hunters and anglers issued a news release calling for the complete closure of the fall moose hunt in Duck Mountain and Porcupine Forest. It follows Manitoba Conservation’s 2023 aerial survey results, which indicate “significantly declining moose populations” in the game-hunting areas in western Manitoba.

It wouldn’t be the first time for a moose conservation closure there. In 2011, licensed and Indigenous hunters supported a full closure of the moose hunt after a 2010 survey the showed moose population had fallen in both areas to 2,471 animals.

Another subdivision, another city problem

So, here we go again folks. We just get the protection of the Lemay Forest done and dusted and bingo, there’s another proposed subdivision for 23 homes on two-acre flood plain lots right across the Red River from the Lemay on the old Daman Farm site.

On World Rhino Day, South Africa marks progress but still loses a rhino daily to poachers

DINOKENG GAME RESERVE, South Africa (AP) — The Dinokeng Game Reserve in South Africa has a thriving rhino population, but their exact numbers and the details of the security operation that keeps them safe from poaching are closely guarded secrets.

They are the protocols that reserves with rhinos follow to ensure they're not the next target for poachers who still kill on average one rhino every day in South Africa for their horns despite decades of work to save the endangered species.

South Africa has the largest populations of both black and southern white rhinos of any country and sees itself as the custodian of the animals' future.

As conservationists mark World Rhino Day on Monday, South Africa remains in a constant and costly battle against poaching nearly 30 years after black rhinos were declared critically endangered, and more than a half-century since southern white rhinos were on the brink of extinction with just a few dozen left.

Bidding an unfond farewell to the fitness test

Goodbye — and good riddance.

A new collective bargaining agreement means a long-standing pre-season ritual — timed sprint skates, measured jumps, weight-lifting contests and lung-capacity tests — is about to become a thing of the past. This September marks the final round of fitness testing, a development that Winnipeg Jets centre Mark Scheifele nearly commemorated with a T-shirt on Wednesday.

So why was this such a sore spot for players?

“I think it stems from last year and a lot of injuries coming in the pre-season, a lot of marquee guys around the league,” said Jets winger Kyle Connor.

Province creates hunting buffer zone on Bloodvein First Nation

The Manitoba government is creating a buffer zone restricting where non-Indigenous hunters can harvest moose on Bloodvein First Nation’s traditional lands.

Manitoba Natural Resources and Indigenous Futures Minister Ian Bushie announced the change late Monday as moose season began for game hunting areas 17, 17A and 17B that includes the traditional areas of the First Nation, located 285 kilometres north of Winnipeg.

The community, which established a check stop to prevent illegal drugs and contraband from entering the First Nation, warned “outside hunters” on social media weeks ago that they’re not welcome to take moose on their traditional lands.

The Manitoba Wildlife Federation has questioned the First Nation’s authority to block licensed hunters with a moose tag from the area and called on the provincial government to intervene.

Very hungry caterpillars very good for biodiversity

Widely considered a pest and a scourge, a leaf-chomping defoliator dedicated to decimating crops, boring into buds and biting down blossoms as it works to satiate its inexhaustible appetite, a new nature documentary reveals there’s more to the much-maligned caterpillar than meets the eye.

The larval creature takes centre stage in Winnipeg filmmaker Jeff McKay’s documentary feature The Extraordinary Caterpillar.

His hour-long film takes viewers on a journey to understanding why the famously “very hungry caterpillar” is a key player in maintaining biodiversity.

“Caterpillars are right at the centre of the food chain, they are key to the food chain working as it should,” McKay says.

Supervised consumption site expected this year will ‘definitely’ open before NDP’s first term ends, addictions minister says

The province will have a supervised consumption site before the next election, Manitoba’s addictions minister promised Friday after unveiling a memorial stone to those who’ve died of drug overdoses.

Housing, Addictions and Homelessness Minister Bernadette Smith told reporters that the government isn’t going to rush the establishment of an overdose prevention site.

“We want to do our due diligence in terms of consulting, making sure that we’re getting it right,” Smith said on the grounds of the Manitoba legislature after an International Overdose Awareness Day rally.

Last month, Smith said the province was “forging ahead” with opening a supervised consumption site in Winnipeg this year. On Friday, she was asked again about an opening date — if it might not be until next year or later in the government’s four-year mandate, which is nearly half over.

One Tech Tip: Ditch the chatbots and take your AI nature apps on a birdwatching hike

I didn't notice the scarlet tanager until the alert appeared on my phone: “Merlin heard a new bird!”

Despite its brilliant plumage — jet-black wings on a crimson body — the songbird can be a hard one to spot in a forest because it prefers to stay high in the canopy. It sounds a little like a robin to an untrained ear.

But the free Merlin Bird ID app detected a scarlet tanager was likely nearby by using artificial intelligence to analyze my phone’s live sound recording. I paused my hike, quietly scanned the treetops, saw the bird as it kept singing and clicked a button to add the species to my growing "life list" of bird sightings. Digital confetti burst on my screen.

Like a real-world version of Pokémon Go, a gotta-catch-'em-all drive to add to my Merlin list has helped me find a great kiskadee in Mexico and a rusty-cheeked scimitar-babbler in the Himalayas. But sometimes the greatest revelations are close to home, as more AI nature app users are starting to discover.

Searing heat draws visitors to California’s Death Valley, where it’s tough to communicate the risks

DEATH VALLEY NATIONAL PARK, Calif. (AP) — Ray Estrada's 11-year-old grandson is used to Las Vegas' scorching summers, but he'd always wanted to experience the heat in one of the Earth's hottest places. So Estrada recently drove him to Death Valley National Park, with an umbrella, extra water and electrolytes in tow. That day, the thermometer soared to 118 F (47.78 C).

“We have to be very careful when we go out there,” Estrada told him. “If you start feeling dizzy or whatever... we’re just gonna turn back and be safe so we can do this again another time.”

The extreme temperatures in this stretch of California desert attract visitors every year, some determined to finish a grueling, multiday race, others just curious about the sizzling heat and the landscape's vast beauty. Yet despite the warnings, the heat kills one to three people annually, and park rangers respond to overheated visitors multiple times per week, making communication about heat safety a priority for the National Park Service.

But that's easier said than done.

McGill University team develops AI that can detect infection before symptoms appear

MONTRÉAL - Researchers at McGill University say they developed an artificial intelligence platform that can predict when someone is about to come down with a respiratory tract infection before they start to feel sick.

In what researchers are calling a "world first," the study involved participants who wore a ring, a watch and a T-shirt, all of which were equipped with censors that recorded their biometric data. By analyzing the data, researchers were able to accurately predict acute systemic inflammation — an early sign of a respiratory infection such as COVID-19.

Published in The Lancet Digital Health, the study says the AI platform can one day help doctors address health problems much earlier than they normally would, particularly in patients who are fragile and for whom a new infection could have serious consequences. It could also potentially reduce costs for the health-care system by preventing complications and hospitalizations.

"We were very interested to see if physiological data measured using wearable sensors … could be used to train an artificial intelligence system capable of detecting an infection or disease resulting from inflammation," explained the study's lead author, Prof. Dennis Jensen of McGill University's department of kinesiology and physical education.

From science experiments to ordering dinner, trying new things can pay valuable dividends

Among the many technical terms from fields such as neuroscience, artificial intelligence, applied mathematics and genetics found in this fascinating new book by bestselling Canadian science writer/distance runner/physicist Alex Hutchinson, the reader discovers “prediction error.”

It’s a term that comes from studies of how the brain makes sense of the impressions presented to it by the senses. The brain doesn’t simply receive sensory data; rather, it continually makes predictions based on partial sense data and feeds these back to the senses. When we get lost, the predictions we make tend to be errors.

We also carry a variant of the gene DRD4 that gives us a happy endorphin boost when our rate of prediction error declines. That genetic variant, Hutchinson writes, emerged 40-50,000 years ago, “right around the time when our ancestors began their long, multi-pronged march to the farthest corners of the globe. It was a march, the findings hinted, spurred in part by dopamine.”

Appropriately enough, The Explorer’s Gene will be picked up by many readers as a result of a prediction error. Judging by the title and the historic mountaineering photo on the cover, readers may assume the book is a story of outdoor adventure.

Commuter traffic stops for whales on Australia’s humpback highway

PORT STEPHENS, Australia (AP) — The ferry was late, but not because of the usual traffic. Sydney commuters watched from an idling boat this month as humpback whales the size of buses surfaced nearby, halting the vessel’s passage across the harbor. The curious mammals seemed to be watching them back.

In June and July, it’s not uncommon for whales to stop water traffic in Sydney. Winter heralds the opening of the so-called humpback highway, a migratory corridor along Australia's east coast used by about 40,000 of the massive creatures as they travel from feeding grounds in freezing Antarctica to tropical breeding areas off Queensland state.

“It’s blubber to blubber,” said Dr. Vanessa Pirotta, a wildlife scientist at Macquarie University in Sydney and author of the book “Humpback Highway.” During peak traffic periods the bustling coastal city of 5.5 million people becomes one of the world’s few urban centers where you might see a breaching whale on your morning walk, while buying a coffee, or waiting at a bus stop – anyplace you can see the ocean.

Whales cruise close to shore

More than 7,000 elms felled in Winnipeg last year due to disease

A city report reveals elm trees were chopped down more than expected last year due to Dutch elm disease.

Should you let pets sleep next to you? (Does it even matter what the experts say?)

It turns out, our furry best friend might be our sleep enemy.

Lots of pet owners let their animals sleep on the bed with them, which usually disrupts sleep. But many would say it’s worth it.

And researchers don't necessarily disagree.

Melissa Milanak, a professor at Medical University of South Carolina specializing in sleep health, said most people at her clinic say their pets disturb them often at night.

Enhanced Games perpetuate a growing problem

We appear to be entering a new golden age of steroids.

Years of scandals out of the Olympics, pro baseball, pro wrestling, and other athletic fields should have put to bed the notion that there is any athletic or cultural value in using performance-enhancing drugs, or PEDs, to get an edge. With every suspension, with every prize stripped from a competitor or left tainted by the way it was obtained, the message was clear — it’s cheating, and it’s not worth it.

Some haven’t received the message. The Enhanced Games hopes to hold its first-ever event in Las Vegas, Nev.

The Enhanced Games, as the name suggests, is a multi-sport athletic competition in which athletes are openly using PEDs. The games’ website makes much ado about the close supervision the athletes will be under, overseen by medical professionals to ensure their health and safety.

Olympic boxing champ Imane Khelif must undergo genetic sex screening to fight for new governing body

Olympic boxing champion Imane Khelif must undergo genetic sex screening to participate in upcoming events with the sport's new governing body.

World Boxing announced mandatory sex testing for all athletes Friday. The governing body specifically mentioned Khelif when announcing the policy, saying the Algerian gold medal winner must be screened before she will be approved to fight at any upcoming events, including the Eindhoven Box Cup next month in the Netherlands.

“The introduction of mandatory testing will be part of a new policy on ‘Sex, Age and Weight’ to ensure the safety of all participants and deliver a competitive level playing field for men and women,” World Boxing wrote in a statement. The fighters' national federations will be responsible for administering the tests and providing the results to World Boxing.

Khelif won a gold medal at the Paris Olympics last summer amid international scrutiny on her and Taiwan's Lin Yu-ting, another gold medal winner. The previous governing body for Olympic boxing, the Russian-dominated International Boxing Association, disqualified both fighters from its 2023 world championships after claiming they had failed an unspecified eligibility test.

Army Corps analysis finds Great Lakes pipeline tunnel would have sweeping environmental impacts

Building an underground tunnel for an aging Enbridge oil pipeline that stretches across a Great Lakes channel could destroy wetlands and harm bat habitats but would eliminate the chances of a boat anchor rupturing the line and causing a catastrophic spill, the U.S. Army Corps of Engineers said Friday in a long-awaited draft analysis of the proposed project's environmental impacts.

The analysis moves the corps a step closer to approving the tunnel for Line 5 in the Straits of Mackinac. The tunnel was proposed in 2018 at a cost of $500 million but has been bogged down by legal challenges. The corps fast-tracked the project in April after President Donald Trump ordered federal agencies in January to identify energy projects for expedited emergency permitting.

A final environmental assessment is expected by autumn, with a permitting decision to follow later this year. The agency initially planned to issue a permitting decision in early 2026.

With that permit in hand, Enbridge would only need permission from the Michigan Department of Environment, Great Lakes and Energy before it could begin constructing the tunnel. That's far from a given, though.

Mother of jailed Egyptian democracy activist hospitalized after resuming hunger strike

LONDON (AP) — The mother of a pro-democracy activist imprisoned in Egypt is seriously ill in a London hospital after resuming a hunger strike aimed at pressing for her son’s release, her family said Friday.

Laila Soueif was admitted to St Thomas’s Hospital on Thursday night with dangerously low blood sugar levels.

“A couple of hours ago I thought we were going to lose her,” her daughter, Sanaa Souief, said outside the hospital. “The bottom line is, we’re losing her.”

She added: “(Prime Minister) Keir Starmer needs to act now. Not tomorrow, not Monday, but right now.”

Dive-bombed or not, Vancouverites are still pro-crow, researchers say

VANCOUVER - Along her journey towards understanding Vancouver's crows, psychology professor Suzanne MacDonald says she made a friend.

It's a crow that brings her gifts after she set up a bird feeder at her home in the neighbourhood of Kitsilano.

Once, it was a barnacle-covered shell, which MacDonald treasures. Other times, it was "bits of garbage" that MacDonald doesn't fancy much, though she "appreciates the sentiment."

"I think he definitely recognizes me. When other people go out on my patio, he doesn't come to them. He knows me," said MacDonald.
