Body’s cellular makeup leads to big, existential questions

French science journalist and author Lise Barnéoud’s first book Hidden Guests is a fascinating, well-researched, atmospheric book on micro-chimerism — the presence of genetically distinct cells from one person circulating in another person.

Talking cows? N.S. researchers think they are getting closer to understanding moos

HALIFAX - If a cow moos in a barn and no one is around to hear it, could you still understand what it’s trying to say?

Researchers at Dalhousie University are hoping to answer that question.

Led by Dr. Ghader Manafiazar, the team at Dalhousie’s agricultural campus in Truro, N.S., has been recording and analyzing cow noises to see whether the animals have different vocal patterns.

Humans can utter words using various inflections and meanings, said Manafiazar, a professor in the faculty of agriculture. His research is trying to determine whether the same holds true for animals. “When they say ‘moo,’ is it different from saying ‘moooooo’?”

Skating trail expected to open in time for New Year’s Day activities at The Forks

Skaters, rejoice: the Nestaweya River Trail at The Forks could be open as early as New Year’s Day, marking one of its earlier openings in recent years.

The port rink on the Assiniboine River and a small section of the the iconic river trail opened on Dec. 31 last year. The earliest recorded opening of the six-kilometre skating trail was Dec. 21, 2013.

“We had a good freeze this year… and we’re hoping for a nice, long season this year,” Adam Dooley, spokesperson for The Forks, said Monday.

Sections of the trail, which snakes along the Red and Assiniboine rivers and meets at The Forks port, have some slush owing to recent snowfall and may take more time to open, Dooley said.

Goats set for farm’s traditional Christmas tree feast

It’s a holiday feast fit for a goat.

Fir, spruce and pine trees are as delicious as turkey and trimmings to about 20 goats at a farm just south of Winnipeg.

Aurora Farms will once again welcome donations of trees once the presents have been opened, the lights turned off, and the ornaments removed.

“Goats are naturally browsers rather than grazers; in the wild, they’ll prefer bushes and shrubs, kind of heartier foraging, over pastureland,” said Aynsleigh Kerchak, general manager at Aurora. “For them, they like a chance to deal with the leaves and needles on the trees.”

U of M researchers studying whether genetic testing helps zero in on effective mental-health treatment meds

A team of University of Manitoba researchers is recruiting people seeking mental-health treatment for a study that could take the guesswork out of medication with the help of genetic testing.

The study will offer free pharmacogenomic testing — which predicts how a person may react to medications based on their genetic makeup — to 200 adults who are looking to start a new medication or switch their medication treating a mental-health issue.

“Someone with mental-health conditions, they (try) multiple medications, and sometimes it takes months or years to get to a point where those drugs work for them, or to have less side effects,” said Dr. Abdullah Maruf, the lead investigator on the study and assistant professor in U of M’s College of Pharmacy.

“Pharmacogenomic testing can find out how our body will respond to these kinds of medication.”

How does climate change affect the likelihood of extreme rain? Federal department aims to publish rapid results

Federal scientists will start to publish rapid results looking at how much more likely major rainstorms have become due to climate change.

Environment and Climate Change Canada says it's expanding its rapid attribution system, so far used to analyze extreme temperatures, to also include extreme precipitation.

"This area of research supports important decision-making that helps Canadian communities prepare for and adapt for the changing frequency and severity of extreme weather events," said Madalina Surcel, a climate extreme specialist with the department.

Officials say they have already run the tool on 42 extreme precipitation events across Canada since June. They say the vast majority of those events were up to two times more likely to happen because of climate change, and three were up to 10 times more likely.

Killer whales and dolphins may be helping each other hunt of B.C. coast: new report

HALIFAX - Scientists have found evidence that two unlikely collaborators — killer whales and dolphins — may be helping each other find and feast on salmon off the coast of British Columbia.

Sarah Fortune, an assistant professor in oceanography at Halifax’s Dalhousie University said it would appear the massive fish-eating whales may be working with Pacific white-sided dolphins, which have been spotted eating the salmon chunks the killer whales produce.

She is a co-author of a paper published Thursday in Scientific Reports that found the two species appear to be working together while they forage.

Recordings picked up "this audible crunch as the whale bites down, then you see these fragments of fish that are released,” and then dolphins swim in to eat the pieces, Fortune said.

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.”

Beleaguered parents of young children with diabetes ask province for help in schools

Parents of children in elementary school with Type 1 diabetes pleaded for help from the province Tuesday at the legislature.

Two mothers — one who has to leave her job at lunch, the other who had to quit her job altogether — in order to get to their children’s schools in time to make insulin-pump adjustments say other provinces, including B.C. and Nova Scotia, have trained school staff to help.

“It’s heartbreaking to have to gauge whether or not I can maintain my livelihood or my child’s health care,” said Christy Peterson, whose five-year-old daughter Lillian is on an insulin pump.

The pumps support better blood-glucose management, help reduce the risk of long-term diabetes complications and their use results in fewer insulin injections.

Hydro to cut down more than 260 trees on stretch of Selkirk Avenue

Manitoba Hydro is cutting down 262 mature trees growing near power lines along a north Winnipeg street, drawing objections from the city and disappointment from canopy advocates.

U of M over the moon about satellite’s lunar launch

A milk-carton sized satellite built by Manitoba researchers will go where no Canadian spacecraft has gone before — the moon’s orbit.

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.

Greenwashing rules to be scaled back, but scope of change remains unclear

TORONTO - Canada's greenwashing rules are being scaled back, but it remains to be seen what the changes mean for businesses wanting to talk about their environmental record.

In the federal budget released last week, the government said it plans to remove parts of the greenwashing laws, passed in June last year, that are part of the Competition Act.

"These “greenwashing” provisions are creating investment uncertainty and having the opposite of the desired effect with some parties slowing or reversing efforts to protect the environment," the government said in the budget.

Specifically, the government says it plans to remove the rule that business environmental claims have to be backed up by internationally recognized methodology, as well as removing the option for third parties such as environmental groups to be able to challenge claims.

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.

Three scientists at US universities win Nobel Prize in physics for advancing quantum technology

STOCKHOLM (AP) — Three scientists won the Nobel Prize in physics Tuesday for research on the strange behavior of subatomic particles called quantum tunneling that enabled the ultra-sensitive measurements achieved by MRI machines and laid the groundwork for better cellphones and faster computers.

The work by John Clarke, Michel H. Devoret and John M. Martinis, who work at American universities, took the seeming contradictions of the subatomic world — where light can be both a wave and a particle and parts of atoms can tunnel through seemingly impenetrable barriers — and applied them in the more traditional physics of digital devices. The results of their findings are just starting to appear in advanced technology and could pave the way for the development of supercharged computing.

The prizewinning research in the mid-1980s took the subatomic “weirdness of quantum mechanics” and found how those tiny interactions can have real-world applications, said Jonathan Bagger, CEO of the American Physical Society. The experiments were a crucial building block in the fast-developing world of quantum mechanics.

Speaking from his cellphone, Clarke, who spearheaded the research team, said: “One of the underlying reasons that cellphones work is because of all this work."

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.
