16,000 fossil footprints in central Bolivia reveal dinosaur behavior

TORO TORO, Bolivia (AP) — Legend once had it that the huge, three-toed footprints scattered across the central highlands of Bolivia came from supernaturally strong monsters — capable of sinking their claws even into solid stone.

Then scientists came here in the 1960s and dispelled children's fears, determining that the strange footprints in fact belonged to gigantic, two-legged dinosaurs that stomped and splashed over 60 million years ago, in the ancient waterways of what is now Toro Toro, a village and popular national park in the Bolivian Andes.

Now, a team of paleontologists, mostly from California’s Loma Linda University, have discovered and meticulously documented 16,600 such footprints left by theropods, the dinosaur group that includes the Tyrannosaurus rex. Their study, based on six years of regular field visits and published last Wednesday in the peer-reviewed journal PLOS One, reports that this finding represents the highest number of theropod footprints recorded anywhere in the world.

“There’s no place in the world where you have such a big abundance of (theropod) footprints,” said Roberto Biaggi, a co-author of the study led by Spanish paleontologist Raúl Esperante. “We have all these world records at this particular site.”

What happens when your immune system hijacks your brain

“My year of unraveling” is how a despairing Christy Morrill described nightmarish months when his immune system hijacked his brain.

What’s called autoimmune encephalitis attacks the organ that makes us “us,” and it can appear out of the blue.

Morrill went for a bike ride with friends along the California coast, stopping for lunch, and they noticed nothing wrong. Neither did Morrill until his wife asked how it went — and he'd forgotten. Morrill would get worse before he got better. “Unhinged” and “fighting to see light,” he wrote as delusions set in and holes in his memory grew.

Of all the ways our immune system can run amok and damage the body instead of protecting it, autoimmune encephalitis is one of the most unfathomable. Seemingly healthy people abruptly spiral with confusion, memory loss, seizures, even psychosis.

Author goes far and wide on quest to document all plants native to Manitoba

When Diana Bizecki Robson was growing up in Saskatoon during the 1970s, she enjoyed riding her bike to parks and riverbanks where she spent hours studying the diversity of wild plants and their pollinators.

After deciding to become a biologist, Bizecki Robson worked for a few years as an environmental consultant which allowed her to conduct plant surveys. But it was when the opportunity to work at the Manitoba Museum came along — in October 2003 — that she could finally pursue the type of field work and research she loves.

Today, Bizecki Robson is the curator of botany at the Manitoba Museum. She oversees a herbarium which holds over 50,000 specimens.

“One of the things I discovered as part of a collection assessment project that I did when I first got here was that the museum did not have a specimen of every single species of plant or fungus or lichen (from this province) in its collection,” said Bizecki Robson.

How Canada can regain its measles elimination status

TORONTO - Infectious disease experts say Canada's loss of measles elimination status shows how badly investment is needed in public health, rebuilding vaccine confidence and solving the primary care crisis.

On Monday, the Pan American Health Organization (PAHO) revoked the measles-free status Canada has had since 1998 because an outbreak of the virus across several provinces has lasted for more than a year.

Dawn Bowdish, an immunologist and professor at McMaster University, said cuts to public health funding, the lack of a national vaccine registry and a shortage of family doctors — all while misinformation about vaccines is circulating widely — have contributed to the rise of measles.

"There's no two ways about this. This will take money — a lot of money — and a lot of investment. And it will take a lot of political will," Bowdish said

City tries to get the most bang for its (sewage) buck

The City of Winnipeg is exploring new ways to reuse its treated sewage sludge.

An expression of interest seeks feedback on the best options and technology available to recycle biosolids, a byproduct of the sewage treatment process. The document notes the treated sludge can be composted, used like a fertilizer, or even be transformed to produce energy.

A massive $3-billion upgrade to the city’s North End sewage treatment plant will add new biosolids facilities that improve the end byproduct, which means the city could soon have more options to reuse it, said Cynthia Wiebe, Winnipeg water and waste’s manager of engineering services.

“The key difference is that there are no pathogens in the (biosolids from the new facility),” said Wiebe.

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.

Will electric tractors gain traction? At a pilot event for farmers, researchers see possibilities

EAST LANSING, Mich. (AP) — In the soft dirt of an indoor horseback riding ring last month, a group of farmers got ready to test drive a new piece of equipment: an electric tractor.

As they took turns climbing in — some surprised by its quick acceleration — they gave real-time feedback to the Michigan State University researchers who have been developing it for over two years.

The farmers remarked on the motor's quiet whir. Most were intrigued, or at least open to the idea. Some were concerned that the battery on the underside of the carriage would mean a lower clearance over the field, while others worried that it would simply be too expensive.

“What we hope to do when we retire is we want to get everything electric on the farm. The tractor is the last electric implement to get,” said Don Dunklee, one of the farmers to provide feedback. He runs a small organic vegetable farm that's relied on wind and solar for decades.

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.

Residents pour cold water on proposed development in St. Vital

Some south St. Vital residents hope to stop a development proposal to build 23 new homes over fears the construction would put their well water at risk.

The proposal aims to add the homes at 45 Daman Farm Rd., 100 Jean Louis Rd. and 2974 St. Mary’s Rd., a 57-acre property on the west side of St. Mary’s Road in the St. Vital Perimeter South neighbourhood. The area is located within city limits but does not have city water and sewer service.

“This particular property lies in a sensitive groundwater area and every well that’s drilled in this area just contaminates the water even further by adding more salt,” said Michelle Olivson, who lives in the area.

City staff recommended the housing application be rejected over the groundwater concerns but city council’s property and development committee voted in favour of the project Friday, echoing a previous community committee vote.

Elon Musk’s Neuralink brain chip implanted into two quadriplegic Canadian patients

TORONTO - Two Canadian patients with spinal cord injuries have received Neuralink brain implants that have allowed them to control a computer with their thoughts.

They are part of the first clinical trial outside of the United States to test the safety and effectiveness of Elon Musk's Neuralink wireless brain chip, which he introduced to the public in 2020, and was first implanted in a paralyzed American in 2024.

The Canadian men, both around 30 years old – one from Ontario, the other from Alberta – have limited or no ability to use their hands.

Dr. Andres Lozano, a neurosurgeon at University Health Network who led the surgical team at Toronto Western Hospital, said the patients could move a computer cursor almost immediately after the surgery. They were able to leave the hospital following their respective procedures on Aug. 27 and Sept. 3 the next morning, he said.

Second summer of motorized boat ban, uncertainty going forward raise longer-term concerns for tourism-driven economy inside Riding Mountain National Park

WASAGAMING — As the sun shimmers over Clear Lake’s still waters, everything appears smooth. But there is an undercurrent of uncertainty running through Manitoba’s most popular national park.

Riding Mountain, and other national parks across Canada, are increasingly facing difficult environmental challenges.

For Riding Mountain, it’s the invasive zebra mussel species. In Alberta’s Jasper National Park, it was 2024’s devastating wildfire that caused more than $1 billion in damages. In Nova Scotia, tinder-dry conditions this summer led to the controversial decision to close back-country access in two national parks — Cape Breton Highlands and Kejimkujik.

This is the new reality for places such as Wasagaming, Riding Mountain’s picturesque townsite that borders on Clear Lake — where bureaucratic decisions to address environmental threats run counter to the desires of residents and tourists who want to enjoy popular summer destinations to the fullest.

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.

Gardening’s hidden benefits: How digging in the dirt could bolster mental wellbeing

If you spend any time gardening, you probably understand what I mean when I say it feels good — despite the lifting, sweating and straining involved. Yes, exercise is good for our bodies, but there’s something about digging in the dirt while listening to a bird soundtrack that lifts my spirits. Even the scent of the soil and mulch makes me happy.

As it turns out, there are scientific reasons for this.

In fact, there’s an entire field called horticultural therapy that’s dedicated to using “plant-based and garden-based activities to support people who have identified treatment needs,” according to Karen Haney, a horticultural therapy instructor at UCLA Extension in Long Beach, California.

“Research suggests 20-30 minutes (of gardening) a few times a week can reduce stress and lift mood, with benefits increasing the more regularly one gardens,” says Sarah Thompson, a professionally registered horticultural therapist in Boise, Idaho.

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.

Wildfire smoke changing outdoor sports landscape

Air quality concerns due to wildfire smoke are changing the landscape of sporting events in Winnipeg. From community centre-run programs to professional leagues, outdoor sports have been impacted by smoke delays, cancellations and playing in less than ideal conditions, leading some to rethink how summer outdoor seasons should be planned going forward.

Krista Fraser-Kruck, general manager of Riverview Community Centre in South Osborne, which offers baseball, soccer, softball, ultimate (frisbee) and summer day camps, says wildfire smoke has forced cancellations and caused rescheduling challenges, especially difficult in a short summer season.

“The priority is keeping kids safe,” said Fraser-Kruck. “For our community, we just want to keep our kids safe, and so doing what’s in the best interest of their health is our priority.”

For their youth soccer games, Riverview Community Centre follows the Winnipeg Youth Soccer Association’s policy, which calls for citywide cancellations if Environment Canada’s Air Quality Health Index (AQHI) reaches seven or higher.
