David Suzuki is turning 90. Environmentalists may have ‘lost, big time,’ but he still has hope

David Suzuki admits defeat — at least in some respects.

The geneticist-turned-environmentalist, who is days away from his 90th birthday, reflected on his legacy as he prepared to release his latest book, "Lessons from a Lifetime," which compiles photos and stories from his life, as well as testimonials written by those he inspired.

"To me, the important legacy that I want to tell my grandchildren is, look, I tried. I love you. I did the best I could for you. And I tried," he said on a video call last month.

"The measure of a person is not whether they succeeded — because we've lost, environmentalists have lost, big time — but that we tried."

Churchill port could further stunt polar bear growth: U of M researcher

Manitoba’s bold plan to transform the Port of Churchill into a shipping powerhouse could have a negative effect on the area’s treasured polar bear population, which fuels its tourism trade, new research shows.

Oldest known whale recording could unlock mysteries of the ocean

A haunting whale song discovered on decades-old audio equipment could open up a new understanding of how the huge animals communicate, according to researchers who say it’s the oldest such recording known.

Speed limits and safety — follow the science

The premier of Manitoba recently appeared hesitant about collaborating with Winnipeg City Council on a public works proposal to lower the city’s default residential speed limit from 50 km/h to 40 km/h. Without a provincial amendment to the Highway Traffic Act, the city says implementing the change would require installing signs on hundreds of streets, at a cost of up to $10 million to taxpayers.

Years of training keep Artemis II crew mission-ready, researcher says

MONTREAL - Despite the delays for NASA's Artemis II mission around the moon and back, a space medicine researcher says the crew, which includes Canadian astronaut Jeremy Hansen, are physically ready for when the time comes to launch.

"They've been preparing for years, so what is a few more months," said Dr. Farhan Asrar, a physician, space medicine researcher and associate dean at Toronto Metropolitan University's School of Medicine.

"One thing that I've always kind of appreciated and respected in the life of astronauts … is it's always expecting the unexpected and how do you best prepare for that?"

NASA has targeted an April 1 launch for Artemis II, with a six-day launch window running through April 6 announced last week.

Pioneering scientist Suzuki reflects on his life’s work

It is hard to believe that Vancouver’s David Suzuki, an internationally renowned geneticist and environmental activist best-known in Canada for his popular television series The Nature of Things with David Suzuki, turns 90 years old on March 24.

Canada, Manitoba lagging behind promise to meet 2030 target of protecting more land and water

There are just four years left on the clock for Manitoba — and the rest of the country — to meet a promise to conserve 30 per cent of land and water by 2030.

But halfway through the timeline adopted at the United Nations Convention on Biodiversity in 2022, Canada has made little progress, adding less than one percentage point to its protected land tally and three points to its protected waters.

The country needs to double its protected areas to meet its target, known as 30-by-30. But conservation groups, including the Wilderness Committee and the Canadian Parks and Wilderness Society, warn progress could stall even further as federal funding for conservation initiatives is set to run out at the end of the month — and there’s no indication it will be renewed.

“We have a conservation economy that we can build on, that gives local jobs, that helps honour our Indigenous reconciliation commitments,” Sandra Schwartz, national executive director of the Canadian Parks and Wilderness Society, said.

NASA clears its Artemis moon rocket for an April launch with four astronauts following repairs

CAPE CANAVERAL, Fla. (AP) — NASA cleared its moon rocket on Thursday for an April launch with four astronauts after completing the latest round of repairs.

The 322-foot (98-meter) rocket will roll out of the hangar and back to the pad next week at Florida's Kennedy Space Center, leading to a launch attempt as early as April 1. It will mark humanity's first trip to the moon in more than 50 years.

The Artemis II crew should have blasted off on a lunar flyaround earlier this year, but fuel leaks and other problems with the Space Launch System rocket interfered.

Although NASA managed to plug the hydrogen fuel leaks at the pad in February, a helium-flow issue forced the space agency to return the rocket to the Vehicle Assembly Building for repairs, bumping the mission to April.

No time for stolen hours

I’m a time zone and time change veteran.

I spent almost two years living in Saskatchewan, where the clocks never change from Central Standard Time, and you just learn to live with it.

I also spent many years living in a province knocked askew from the top of the clock, where, when everyone else was celebrating New Year’s at midnight, we were already at 12:30 a.m.

I’ve lived in the Newfoundland time zone, along with Atlantic, Eastern, Central and Mountain zones, along with every one of their spring-forward, fall-back time changes.

King penguins are the rare species benefiting from a warming world. But that could change

WASHINGTON (AP) — The warming world has disrupted the timing for plant and animal reproduction, and it's usually bad news for species that depend on each other — like flowers blooming too early and pollinating bees arriving too late. But researchers have found the rare critter that's getting a boost from the change: King penguins.

A new study of 19,000 king penguins in a sub-Antarctic island chain found their breeding is starting 19 days earlier than it did in 2000. Mating earlier has increased the breeding success rate by 40%, according to a study in Wednesday's journal Science Advances.

The study of timing in nature is called phenology. It's been a major concern for biologists because predators and prey and pollinators and plants are mostly adapting to warmer climates at different rates. And that means crucial mismatches in timing.

It's especially common in birds and pollinating species such as bees. Most birds, especially in North America, aren't keeping pace with changes in phenology, according to Clemson University biological sciences professor Casey Youngflesh, who wasn't part of the study.

Pentagon’s chief tech officer says he clashed with AI company Anthropic over autonomous warfare

A top Pentagon official said Anthropic's dispute with the government over the use of its artificial intelligence technology in fully autonomous weapons came after a debate over how AI could be used in President Donald Trump's future Golden Dome missile defense program, which aims to put U.S. weapons in space.

U.S. Defense Undersecretary Emil Michael, the Pentagon's chief technology officer, said he came to view the AI company's ethical restrictions on the use of its chatbot Claude as an irrational obstacle as the U.S. military pursues giving greater autonomy to swarms of armed drones, underwater vehicles and other machines to compete with rivals like China that could do the same.

“I need a reliable, steady partner that gives me something, that’ll work with me on autonomous, because someday it’ll be real and we’re starting to see earlier versions of that," Michael said in a podcast aired Friday. "I need someone who’s not going to wig out in the middle.”

The comments came after the Pentagon formally designated San Francisco-based Anthropic a supply chain risk, cutting off its defense work using a rule designed to prevent foreign adversaries from harming national security systems.

Spacecraft’s impact changed asteroid’s orbit around the sun in a save-the-Earth test, study finds

CAPE CANAVERAL, Fla. (AP) — An asteroid that NASA used for target practice a few years ago was nudged into a slightly different route around the sun, findings that could help divert a future incoming killer space rock, scientists reported Friday.

It’s the first time that a celestial body’s orbit around the sun was deliberately changed. The asteroid that NASA's Dart spacecraft slammed into was never a threat to Earth.

“This study marks a notable step forward in our ability to prevent future asteroid impacts on Earth,” the international research team wrote in Science Advances.

The changes were slight — reductions of just one-tenth of a second and one-half of a mile (720 meters) to a solar lap spanning two years and hundreds of millions of miles (kilometers), according to the scientists.

Last spring forward for B.C. as it moves to permanent daylight time

VICTORIA - British Columbia's southern population centres will be facing winter sunrises around 9 a.m. — and around 9:30 a.m. in the north — after the decision to adopt year-round daylight time, springing forward by one hour this Sunday for the last time.

Premier David Eby said Monday the decision is about making life easier for families, reducing disruptions for businesses and supporting a stable, thriving economy.

"British Columbians have been clear that seasonal time changes do not work for them,” Eby said.

He announced the change inside the legislature's Hall of Honour, surrounded by about 40 local elementary schoolchildren, and he addressed them first.

Stargazers in Manitoba have the chance Tuesday to watch the last total lunar eclipse on this side of the world until 2029.

Big dreams, cold reality: Buzz builds for Port of Churchill, but risks could outweigh rewards

The marine town of Churchill, cherished for its wildlife, landscapes and history, has recently taken on a new sense of national importance. Plans to expand Canada’s lone deepwater Arctic port on the shores of Hudson Bay have gained momentum — and investment — in the last year as the country looks north for solutions to an unprecedented conflict with its southern neighbour.

Premier Wab Kinew has pitched the Port of Churchill as an answer to Canada’s trade concerns, and a means of galvanizing both provincial and national economies.

Prime Minister Mark Carney has designated a plan to upgrade the port facilities as “transformative,” committing millions in federal dollars to the project and touting its merits in meetings with European trade partners.

In late January, Kinew announced the province was in talks with several companies, including at least one major energy company, about investing in port expansion.

New football chinstrap designed to lessen force of blows to facemask

Erin Hanson wants to make taking it on the chin in football much safer in Canada.

Guardian Sports officially launched the Guardian Flex chinstrap on Thursday for individual and team sale, with the CFL being among the leagues to have reviewed the item. The product has been engineered to reduce the impact of blows to the facemask.

According to the company, the chinstrap reduces Head Acceleration Response Metric (HARM) scores by up to 35 per cent and targets facemask impacts, which research suggests account for about half of all hits and are an area where traditional helmets underperform.

The chinstrap will be far less noticeable to fans than the Atlanta-based company’s Guardian Cap. Introduced 14 years ago, the soft padded shell fits over a football helmet and is secured by elastic straps attached to the facemask.

The surprising complexity behind the squeak of basketball shoes on hardwood floors

NEW YORK (AP) — As he watched the Boston Celtics play from the stands of TD Garden, one noise kept catching Adel Djellouli's ear.

“This squeaking sound when players are sliding on the floor is omnipresent,” he said. “It’s always there, right?”

Squeaky shoes are part of the symphony of a basketball game, when rubber soles rasp against the hardwood floors as players jab step, cut and pivot and defenders move their feet to stay in front of their assignment.

Returning home from the game, Djellouli wondered how that sound was produced. And as a materials scientist at Harvard University, he had a way to find out.

First Nations awaiting Hydro consults

With licences for two major Manitoba Hydro projects set to expire later this year, affected First Nations await consultation — and want to see change.

Licences for the Churchill River Diversion and Lake Winnipeg Regulation projects, first issued in the 1970s, expire Sept. 1 and Aug. 1, respectively.

The diversion directs water to five stations accounting for roughly 75 per cent of Manitoba’s power generation. The latter project allows Hydro to generate power by manipulating Lake Winnipeg’s water levels.

There is no timeline for the licence renewals, said Environment Minister Mike Moyes. He said that would be dependent on consultations with impacted First Nations.

Family embraces challenges, rewards of launching a fruit orchard

Growing up on a farm near Boissevain taught Kelvin Hildebrandt many things. But becoming an orchardist has meant taking a comprehensive and strategic approach to acquiring a whole new set of skills.

In the process, Hildebrandt has consulted with local orchardists, including well-known growers like Betty Kehler and Bob Pizey who ran Plum Ridge Farm, a popular u-pick orchard located in the Interlake region near Teulon.

“They taught me a great deal,” says Hildebrandt.

Hildebrandt has also been influenced by Jean Spencer who owned a 150-tree apple orchard near Miami. “Jean was very welcoming and let me take care of her trees for a while,” he says.

The delicate art of pressing flowers

When early explorers travelled the four corners of the world in search of botanical treasures and plant knowledge, they faced many challenges collecting and transporting live plant material. In the 19th century, the development of the Wardian case — a glazed box that held soil and water — enhanced the survival rate of live plants on long sea journeys.

But highly detailed botanical illustrations also served as a visual record for early botanists and scientists to study plants from distant parts of the world. The technique of pressing and drying all the parts of individual plants on paper made it possible to preserve plant specimens.

Today, herbariums around the world, including those at Manitoba Museum and the University of Manitoba, house extensive collections of pressed, dried plants stored in specialized, climate-controlled conditions. Scientists use these specimens to determine the rarity of species and understand environmental changes.

Enduring art form

U of M partners with firm behind proposed sand mine to study Manitoba groundwater

University of Manitoba researchers will soon have a new, non-invasive tool to study the province’s vast groundwater resources after inking a partnership with Alberta-based mining company Sio Silica.

“If the technology works … it’s going to provide a mechanism to do real-time monitoring of changes in groundwater,” Ricardo Mantilla, an associate professor in the university’s civil engineering department and lead researcher for the project, said in an interview.

The emerging technology — called absolute quantum gravimetry — can measure changes in gravity caused by changes in groundwater levels, allowing researchers to better understand the flow and storage of underground water resources without the need for “expensive and disruptive” drilling, he said.

“That obviously has applications for (Sio Silica), but it can have very important implications for how we understand groundwater in aquifers in our province.”

More Canadian athletes powered by artificial intelligence at Winter Games

Just for fun, Xavier McKeever and his cross-country ski teammates once tasked ChatGPT to design a training plan for them.

"It was the craziest training plan we've ever seen," said the 22-year-old from Canmore, Alta.

"It basically said you should do intensity every single day. You should do three hours of skiing and then an hour of intensity, and repeat that a few times -- and then you should take a week off completely. We know you can't do that.

"It was pretty funny to see and do, to see Chat GPT can't write a training plan, and that we need our coaching to help us with that."
