Peru court rules in favor of Kichwa territorial rights in the Amazon

Steven Grattan, The Associated Press 3 minute read Thursday, Oct. 16, 2025

BOGOTA, Colombia (AP) — A civil court in Peru has issued a landmark ruling recognizing the territorial rights of the Kichwa people within a protected area in the Amazon — marking a major breakthrough for Indigenous land claims.

The decision affirms that Indigenous stewardship is fully compatible with conservation goals, setting a powerful precedent for rights-based forest protection in Peru, according to the Kichwa people and lawyers involved in the case.

The ruling, issued on May 15 but made public on Wednesday, came after a legal challenge by four Indigenous organizations on behalf of Kichwa communities in the San Martín region. The communities say the state denied their ancestral presence for decades, creating protected areas without consultation or consent.

“The ruling validates their historical presence and their right to demand respect for those territories,” Cristina Gavancho, legal adviser to the plaintiff organizations, told The Associated Press on Thursday. “It recognizes that in doing so, they not only contribute to conservation but must be involved in any state-led measures to implement it.”

L’étudiante trilingue Camila Chacon a remporté au mois de mars le concours Ma thèse en 180 secondes pour l’année 2025 au Manitoba. En à peine trois minutes, elle a su convaincre les jurys à propos d’un sujet sur lequel elle travaille depuis quasiment une dizaine d’années. Elle s’en va maintenant pour le concours national qui a lieu le 7 mai.

Après les quatre présentations des autres candidats, c’est en cinquième et dernière que Camila Chacon, doctorante en physiologie et physiopathologie de l’Université du Manitoba passait pour présenter à l’oral son étude lors du concours Ma thèse en 180 secondes, lancé par l’Association francophone pour le savoir en 2012, dénommée désormais simplement Acfas.

Alors, comment se sentait Camila Chacon devant des jurys issus de différents milieux professionnels, ainsi que devant Jean-Éric Ghia, professeur en immunologie à l’Université du Manitoba et formateur en vulgarisation scientifique et à la présentation de Ma thèse en 180 secondes?

Sirop d’érable, le trésor de Saint-Pierre-Jolys

L’incontournable Festival du Temps des sucres se prépare à revenir au village de Saint-Pierre-Jolys les 5 et 6 avril. Prenant place dans la Cabane à sucre, une extension du musée, les visiteurs pourront festoyer et célébrer ce fameux sirop local aux teintes ambrées.

Le temps se fait plus doux dans le village de Saint-Pierre-Jolys où les récoltes de sirop d’érable ont doucement commencé depuis la semaine du 17 mars.

En effet, des gelées la nuit combinées à des températures plus élevées le jour créent les conditions propices à la saison des récoltes. Ce type de météo permet d’exercer une pression à l’intérieur de l’arbre favorisant ensuite l’écoulement de “l’eau sucrée” comme aime l’appeler Roland Gagné, le gérant de la Cabane à sucre du village.

“Grâce à Mère Nature, l’eau remonte des racines jusqu’en haut de l’arbre. Ça permet de nettoyer les veines de l’érable et ensuite le liquide s’écoule.”

At the start of Premier Wab Kinew’s government’s mandate, it signalled it would work to get Manitoba to a net-zero electricity grid by 2035. With 99 per cent of the province’s electricity already emissions-free, it is a small, but important gap to bridge.

À Saint-Eustache, la compagnie Tritec Concrete se lance dans la commercialisation d’une technologie d’élimination des déchets organiques aux nombreux avantages.

Sur le terrain de la compagnie Tritec Concrete, aux abords de Saint-Eustache à l’ouest de Winnipeg, une machine d’une dizaine de mètres de haut se dresse à l’extérieur, derrière les hangars.

Il s’agit d’un prototype de Rapid Organic Converter (ROC). Celui-ci fonctionne en continu depuis 2016 et a vu le jour sous l’impulsion de Jamie Dufresne, propriétaire de Tritec Concrete, qui a travaillé pendant une bonne partie de sa carrière dans la recherche et le développement.

“Je cherchais un moyen de récupérer les déchets agricoles, que nous brûlions à l’époque, et de trouver un moyen de le granuler ou l’ensacher. Le système actuel consomme tout ce qui est organique.”

Les intempéries hivernales ont parfois des impacts insoupçonnés. Alors que les déplacements ont été rendus difficiles à travers le pays, la Société canadienne du sang doit combler les pertes causées pour répondre à un besoin toujours plus important.

Le temps hivernal s’est montré quelque peu extrême le mois dernier. S’il n’est pas nécessairement évident de faire le lien entre les deux, et bien les aléas météorologiques ont un impact direct sur la collecte de sang au Manitoba et plus largement dans tout le pays.

Aujourd’hui, il faut savoir que, la branche manitobaine de la Société canadienne du sang (SCS), ne compte pas moins de 30 cliniques mobiles. Ces dernières se déplacent trois fois par semaine dans les communautés rurales de la province. Entre autres, Brandon, Portage la Prairie ou bien Selkirk.

Or les intempéries ont provoqué l’annulation de plusieurs centaines de rendez-vous, comme l’explique Rayna Porter, responsable du développement communautaire pour la SCS ici, à Winnipeg.

Slow fashion houses embrace made-to-order to reduce waste

TORONTO - On occasion, fashion designer and clothier Katelyn Woodburn is accused of running a scam.

When a customer makes a purchase without reading the "about" section on her website or following her on social media, they might send an email a week or two later saying something like: "Where's my order? It hasn't even shipped yet? What's going on?" Woodburn recounted from her Vancouver studio.

"Which is a totally reasonable response," she added. Consumers are conditioned to expect instant gratification when it comes to clothes shopping, but that's not really how Woodburn does things.

"I'll say, 'Oh, your shirt is being cut out. We're going to sew it tomorrow.' I tell them the whole process of what's happening. And 100 per cent of the time, I get a response going, 'Oh my gosh, I didn't even realize. This is so cool, no rush at all.'"

Bringing dental care to kids in schools is helping take care of teeth neglected in the pandemic

Michael Casey, The Associated Press 6 minute read Wednesday, Oct. 15, 2025

CONCORD, N.H. (AP) — Tucked away inside the teachers lounge at a New Hampshire elementary school, Amber Warner was having her teeth checked out for the first time.

The 5-year-old sat back on what looked like a beach chair and wore a pair of dark sunglasses as certified public health dental hygienist Mary Davis surveyed Amber's teeth and then with a tiny syringe applied traditional dental sealants, which had the consistency of nail gel.

“Close down and bite your teeth together, bite down like you are biting down on a hot dog or a cheeseburger," Davis told Amber, to ensure the sealants were done properly. After that, Davis flossed all of the “popcorn and the chicken, pizza between your teeth.” The whole visit took 15 minutes.

“Look at you. You are a pro on your first dental visit. I am so proud of you,” Davis said to the kindergartener, who got up from the chair and was hugged by a teacher's assistant.

Some doctors sneak education into their online content to drown out misinformation

Nicole Thompson, The Canadian Press 6 minute read Friday, Oct. 10, 2025

TORONTO - When Dr. Siobhan Deshauer makes online videos, her primary goal is to demystify medicine. Her secondary goal?

"I call it 'smuggling in education,'" said the physician and YouTuber, who boasts nearly a million subscribers on the platform. "You're coming for this mystery and this excitement, but I'm smuggling in some topics that I think are really important and that I'm passionate about."

Some experts say one of the best ways to fight a rising tide of medical misinformation on social media is to drown it out with captivating content backed by science, and Deshauer, an Ontario-based internal medicine and rheumatology specialist, is among a growing cohort of doctors and researchers doing just that.

Take one of her medical mystery videos, for example. In it, Deshauer tells the story of a woman who had lead poisoning. Doctors took ages to figure out what was causing her symptoms, but ultimately realized they were a result of lead in the Ayurvedic supplements she was taking.

Hadfield urges Shatner to 'soak up' spaceflight

One Canadian spaceman to another, former astronaut Chris Hadfield is encouraging William Shatner to follow the wise words of Captain James T. Kirk as he braces himself for a real-life blastoff: "Boldly go."

Hadfield said he quoted the "Star Trek" star's iconic mantra in a note wishing him well on his voyage aboard Jeff Bezos' Blue Origin rocket ship on Wednesday.

The flight was originally planned for Tuesday but Blue Origin has announced it is being delayed 24 hours due to forecasted high winds.

Hadfield, a self-identified Trekkie who commanded the International Space Station, said he's thrilled that after decades of service in the fictional Spacefleet, the Quebec-raised actor will soon get to experience the final frontier for himself.

2 win medicine Nobel for showing how we react to heat, touch

David Keyton And Maria Cheng, The Associated Press 5 minute read Monday, May. 18, 2026

STOCKHOLM (AP) — Two scientists won the Nobel Prize in medicine on Monday for their discoveries into how the human body perceives temperature and touch, revelations that could lead to new ways of treating pain or even heart disease.

Americans David Julius and Ardem Patapoutian separately identified receptors in the skin that respond to heat and pressure, and researchers are working on drugs to target them. Some hope the discoveries could eventually lead to pain treatments that reduce dependence on highly addictive opioids. But the breakthroughs, which happened decades ago, have not yet yielded many effective new therapies.

Julius, of the University of California at San Francisco, used capsaicin, the active component in chili peppers, to help pinpoint the nerve sensors that respond to heat, the Nobel Committee said. Patapoutian, of Scripps Research Institute at La Jolla, California, found pressure-sensitive sensors in cells that respond to mechanical stimulation.

“This really unlocks one of the secrets of nature,” said Thomas Perlmann, secretary-general of the committee, in announcing the winners. “It’s actually something that is crucial for our survival, so it’s a very important and profound discovery.”

I was standing in the backyard next to a very tall tree, sipping the first coffee of the day, trying to think of a topic for today’s column, when suddenly it hit me.

No, I was not struck by a sudden inspiration. I was bonked on the top of my head by a pine cone the size of a regulation volleyball.

In quick succession, several more potentially lethal pine cones plummeted from the sky and thudded into the ground near my feet.

“I can see you up there!” I shrieked, waving my fist at the sky. “You are not going to get away with this!”

Shoal Lake 40 toasts clean water

Melissa Martin 6 minute read Wednesday, Sep. 15, 2021

SHOAL LAKE 40 FIRST NATION – As he raised his glass, Chief Vernon Redsky looked at the water and a memory came rushing back. It reminded him of when he was a kid, he said, and the water in Shoal Lake was crystal-clear like that, back when he and his friends would splash along the shore, drinking from the lake when they got thirsty.

So he thought about that as he clinked his glass against two others, and took a sip. A toast, to the first officially safe tap drinking water in Shoal Lake 40: on Wednesday, after 24 years, the Treaty Three First Nation’s boil water advisory officially ended.

“It’s surreal to be at this moment,” Redsky said at a ceremony to celebrate the achievement, as well as the opening of the community’s new school.

One day earlier, a government official in Kenora, Ont., had officially approved the latest test results from Shoal Lake 40’s new water treatment plant, which started pumping this summer. That night, Redsky couldn’t sleep; he called a former chief to talk about the long road they had travelled to get to this point.

If it walks like a duck and talks like a human, chances are it’s getting scientists very excited and making headlines around the world.

For the record, we’re not talking about Donald or Daffy or some other cartoon duck. No, we’re talking about recordings of an Australian musk duck named “Ripper” repeatedly saying what sounds like “you bloody fool.”

The 34-year-old recording, recently made public, appears to be the first documented evidence of the species being able to mimic sounds and has researchers reviewing the evolution of vocal language learning in birds.

According to news reports, Ripper, a male musk duck reared in captivity at Tidbinbilla Nature Reserve, southwest of Canberra, was recorded vocalizing the sound of doors slamming shut as well as the words “you bloody fool,” a phrase he likely learned from his caretaker.

City eyes bird-friendly buildings

GLAZED windows and limits on lighting are options the City of Winnipeg is considering to save birds from flying into buildings.

Approximately 25 million birds die in Canada annually by colliding with windows, according to a study used as part of the city’s research into the problem.

“We’re losing our birds, especially our migratory birds, at a really fast rate,” said Kevin Fraser, a University of Manitoba associate professor who studies the species. “Light and windows are huge threats.”

Winnipeg is part of the Mississippi flyway, a major migration route for birds.

New show pits sand carvers against each other, Bay of Fundy tides

Alan Small 5 minute read Thursday, Sep. 9, 2021

A new CBC show aims to put the fun in the Bay of Fundy.

The series is Race Against the Tide, and it pits 10 teams of two sand sculptors from around the world against the one of the Earth’s most relentless of timers — the record-breaking tides of the Bay of Fundy, where Atlantic Ocean waves surge between New Brunswick and Nova Scotia.

The fast-paced show, hosted by comedian Shawn Majumder, debuts Thursday at 7 p.m. on CBC with its first two half-hour episodes kicking off a five-week run that combines the labour of packing pounds of sand for a base with the careful carving of grains of sand to create remarkable works of art.

The sculptures are temporary though. The teams are given six hours to create their works, but shortly after they are judged, the Bay of Fundy waves wash the works away.

On one side of the chain-link fence separating Glenelm School from the street, nervous elementary students fidgeted with their masks and bulky backpacks on the playground as they waited to meet new teachers and friends in lines.

On the other side, parents on the sidewalk — among them, Joisy Fernandez — peeked through the grey diamonds with anxieties of their own.

"I wish I could go in there and just stand next to her and say, ‘It will be OK,’" said Fernandez, who dropped off her daughter Natalie for the first day of Grade 5 on Wednesday morning. "As tough as it is on us, we have to show them that (a safe school year) is possible."

Glenelm, a K-6 building at 96 Carmen Ave., has kept its pandemic policy for drop-offs intact this year to prevent congestion on the playground. Parents are discouraged from entering both the Winnipeg school's grounds and building.

New book debunks Winnipeg-lab coronavirus conspiracy theory

CBC News 2 minute read Tuesday, Aug. 31, 2021

A new book concludes co-operation between Canada's National Microbiology Lab in Winnipeg and China's Wuhan Institute of Virology played no part in the origin of the coronavirus pandemic but raises questions about links between one of the researchers fired from the lab and a prominent Chinese virologist affiliated with the military.

Toronto-based freelance journalist Elaine Dewar says she set out to investigate the hypothesis that the coronavirus was leaked from the Wuhan lab by looking at the science and financial and geopolitical interests related to the theory.

As part of that, she looked into whether an approved shipment of Ebola and henipah viruses in March 2019 from the Winnipeg lab to Wuhan had anything to do with the pandemic after conspiracy theories suggesting it did surfaced online.

Japanese garden an enduring cultural experience

Colleen Zacharias 7 minute read Saturday, Aug. 28, 2021

The Japanese Cultural Association of Manitoba, 180 McPhillips St., opened to the public in 1987. The centre offers a wide range of programs which are designed to promote and enhance the understanding of Japanese culture. The centre also serves as the site for a beautiful Japanese garden. Built by Yoshimaru Abe who was born in Japan in 1914 and came to Canada with his family in 1927, the garden is an enduring cultural experience.

Prior to building the garden at the centre, visitors to the Japanese Folklorama exhibit in 1971 and in the years following had the opportunity to see a Japanese garden recreated by Abe. Using moss, rocks, and pieces of wood, Abe recreated an authentic Japanese garden on a concrete arena floor.

A gardener is called niwashi in Japanese. Abe was the distinguished niwashi at the Japanese cultural centre’s garden into his 90’s and was followed by Sam Matsuo, who maintained the garden for 10 years. Both Abe and Matsuo were assisted by dedicated volunteers. Today the niwashi is Raymond Normandeau, who has been involved with the centre for several years as well as in the building of the garden at the Japanese Pavilion at Folklorama. Normandeau will oversee an expansion of the garden at the Japanese Cultural Association — which is slated to begin this fall.

Currently, there are two different areas to the garden. The front garden is a long narrow strip on the outside of the building that faces into a concrete parking lot. The inner garden is an enclosed garden accessed by a short bridge and tall wooden gate. “It is not a pure Japanese garden,” says Normandeau. “It is representative of a Japanese garden. We don’t have the stalwarts of Japanese gardens — bamboo, clipped azaleas, and the black pine which is one of the most popular pine species in a Japanese garden.” But many fine elements of Japanese garden design can indeed be found here.

More than 17,000 years ago, a woolly mammoth roamed enough of the Alaskan landscape to circle the Earth twice.

That's according to a new paper from an international team of researchers who retraced the lifetime of one of the extinct ancient Arctic creatures.

Pit bulls legal, ball pythons banned?

Laura Baker has wanted a pit bull for 20 years, but hasn’t bought one because of the city’s ban.

“I just feel like the whole breed has been so misrepresented, misunderstood and given a raw deal in terms of being able to find loving homes,” the St. James resident said.

If proposed changes to a city bylaw pass, Baker will legally be able to own a pit bull, while it could become illegal to feed wildlife and to leave pets in vehicles at certain temperatures.

The city is looking for feedback on suggestions to its Responsible Pet Ownership bylaw. Winnipeg Public Service reviewed the rules this summer and came back with a number of ideas, including a removal of breed-specific bans.
