BEIJING (AP) — While China's men's soccer team hasn't generated much excitement in recent years, humanoid robot teams have won over fans in Beijing based more on the AI technology involved than any athletic prowess shown.

Four teams of humanoid robots faced off in fully autonomous 3-on-3 soccer matches powered entirely by artificial intelligence on Saturday night in China's capital in what was touted as a first in China and a preview for the upcoming World Humanoid Robot Games, set to take place in Beijing.

According to the organizers, a key aspect of the match was that all the participating robots operated fully autonomously using AI-driven strategies without any human intervention or supervision.

Equipped with advanced visual sensors, the robots were able to identify the ball and navigate the field with agility

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

Greg Beacham, The Associated Press 4 minute read Friday, Oct. 3, 2025

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.

Swiss president pledges aid for Alpine villagers left homeless after glacier collapse

Associated Press, The Associated Press 3 minute read Monday, Oct. 13, 2025

GENEVA (AP) — Switzerland's president on Friday said evacuees from an Alpine village whose homes and businesses were destroyed by a landslide caused by a glacier collapse were “not alone," and the government was calculating ways to help.

Karin Keller-Sutter spoke after a helicopter flight to see for herself the damage to the village of Blatten that was largely destroyed on Wednesday as an estimated 10 millions of tons of mud, ice and rock thundered down from the Birch glacier overhead.

“The force with which the mountain here wiped out an entire village is indescribable,” Keller-Sutter said. “I’d like to tell you all that you’re not alone. The whole of Switzerland is with you, and not just (people) in Switzerland.”

Officials limited access to the area and warned that waters from the Lonza River, which has been dammed up by deposits stacked tens of meters high over a 2-kilometer (1.2-mile) swath of valley, had pooled into a lake. The future course of those waters could not yet be predicted precisely.

SPRINGFIELD, Ky. (AP) — The National Weather Service issued tornado warnings for parts of Kentucky, Tennessee, West Virginia and Virginia on Friday, hours after a harsh storm hit a remote area of central Kentucky, killing one person and injuring seven others.

In Kentucky, Washington County Judge-executive Timothy Graves said two or three houses were destroyed and downed trees temporarily blocked roads.

“We were fortunate this was located in a remote part of the county,” Graves said.

Gov. Andy Beshear canceled a visit planned for Friday to Pulaski and Laurel counties, which were hit by a tornado earlier this month. That storm left 19 dead in the state. Officials were responding to reports of a possible tornado in Washington County, he said in a social media post.

French Open tennis players say nasal strips aren’t just for snoring

Tom Nouvian, The Associated Press 4 minute read Sunday, Sep. 21, 2025

PARIS (AP) — If more tennis players find themselves breathing easier, it might just be thanks to Carlos Alcaraz.

The four-time Grand Slam champion, whose bid for a second consecutive French Open title was scheduled to continue with a third-round match Friday night, has often worn a nasal strip in matches since last season — although not during his first two contests at Roland-Garros this week — and the sport's other athletes took note.

After all, if Alcaraz finds something useful on the court, their thinking goes, maybe it makes sense to give the adhesive bands a shot.

“I saw Carlos playing in it,” said 18-year-old Mirra Andreeva, a semifinalist in Paris last year and the No. 6 women's seed this time. “I’d be pretty interested to try and see if there is really a difference. If he plays matches in it, then probably there is.”

Trump signs executive orders to boost nuclear power, speed up approvals

Matthew Daly And Jennifer Mcdermott, The Associated Press 6 minute read Monday, Sep. 22, 2025

WASHINGTON (AP) — President Donald Trump signed executive orders Friday intended to quadruple domestic production of nuclear power within the next 25 years, a goal experts say the United States is highly unlikely to reach.

To speed up the development of nuclear power, the orders grant the U.S. energy secretary authority to approve some advanced reactor designs and projects, taking authority away from the independent safety agency that has regulated the U.S. nuclear industry for five decades.

The order comes as demand for electricity surges amid a boom in energy-hungry data centers and artificial intelligence. Tech companies, venture capitalists, states and others are competing for electricity and straining the nation's electric grid.

“We’ve got enough electricity to win the AI arms race with China,” Interior Secretary Doug Burgum said. “What we do in the next five years related to electricity is going to determine the next 50" years in the industry.

Inquiry must be called to get answers on sand mine scandal

Tom Brodbeck 5 minute read Friday, May. 23, 2025

It’s pretty clear by now that an inquiry should be called into the Sio Silica scandal.

Ethics Commissioner Jeffrey Schnoor released his long-awaited report into the matter this week. He found that former premier Heather Stefanson, then deputy premier Cliff Cullen and then economic development minister Jeff Wharton, violated the province’s Conflict of Interest Act by attempting to approve a licence for a controversial silica sand mining project after their government was defeated in the Oct. 3, 2023 provincial election.

All three ministers pushed to have a Class 2 licence under the Environment Act approved for Sio Silica, days before the new NDP government was sworn into office.

They did so even though they knew, or ought to have known, that it violated the “caretaker convention,” a longstanding constitutional principle in Canada that prohibits governments from making major policy decisions once a general election is called (unless it’s related to an urgent matter of public importance).

Maximilian Scott is a vertebrate paleontologist who focuses on extinct animal behaviour and behavioural evolution. Scott, 27, from Ovid, Mich., is in the last year of his master’s degree at the University of Manitoba studying mosasaurs, an ancient marine lizard that lived in Manitoba during the late-Cretaceous period.

He also offers tutoring in geology, biology, animal behaviour and conservation to people of all ages. You can find him on Instagram.

Our story doesn’t start with the first book that was written, our story starts a long time before that, a long time before the first humans. It’s all one long story.

Humans have only existed for 200,000 years. The Earth has been around for 4.5 billion years. Life has been around for three billion years, and complex life has been around for 542 million years.

Auto detail shop poised to fight pandemic

Since COVID-19 has taught us to continually wash our hands, and many of us have already cleaned every corner of our homes, it's a sure bet a few of us have also turned our efforts to sanitizing our vehicles.

Your usual Saturday morning ritual of washing your car on the driveway with the garden hose and vacuuming the interior and wiping down hard surfaces with car cleaning products is likely all you'll need to keep your vehicle shiny and safe — but if you know or suspect your vehicle has come into contact with coronavirus, or just want to increase your peace of mind, it may be time to call in a professional.

The majority of auto detail shops, which fall under the same essential services category as automobile repair shops, have remained open during the pandemic.

Tom Segal, 45, the owner of Blue Ocean Auto Detailing in Headingley, has seen it all in the more than 25 years he's been cleaning cars, including dirty diapers, rotten food crammed between seats and rodent infestations, but this is his first pandemic.

L’avenir de l’Arctique au cœur de Breaking Ice

Morgane Lemée de La Liberté pour le Winnipeg Free Press 4 minute read Saturday, Apr. 7, 2018

Breaking Ice, c’est un aperçu de la vie sur un brise-glace de recherche, au beau milieu de l’Arctique. À travers son premier long-métrage documentaire, Christopher Paetkau transmet un message sur des enjeux environnementaux cruciaux pour le Canada et le monde entier. Entre frissons et passion.

Christopher Paetkau, Trevor Gill et Carlyle Paetkau ont fondé la maison de production manitobaine Build Films en 2013. Après plusieurs documentaires et publicités, Breaking Ice est leur plus grand projet. Il vise d’ailleurs à répondre au point central de leur mission: les enjeux de l’Arctique.

“Nous travaillons beaucoup dans l’Arctique, surtout sur des aires marines protégées. Au début, c’était une question de curiosité. Puis, ça nous a vraiment pris aux tripes. Une fois là, on réalise à quel point ces paysages sont complexes et fascinants. Pour nous, l’émotion n’est pas d’avoir une caméra entre les mains. Elle vient d’être capable de transmettre un message.

“Quand vous sentez le sol littéralement fondre sous vos pieds et que vous savez que des gens vivent ici, il y a vraiment de quoi se poser des questions. À mon avis, l’Arctique est d’une actualité brûlante. Il y a tant de choses à entreprendre.”

RÉAL Bérard est l’un des rares explorateurs des temps modernes à partir à l’assaut des rivières capricieuses armé de son canoë, de papier et d’un crayon.

Réal Bérard est en effet le premier à avoir entrepris de cartographier pour le gouvernement puis par passion l’ensemble des rivières manitobaines.

Depuis 1961 le cartographe parcourt ainsi des kilomètres de rivières et des jours durant, pour les dessiner et les décrire dans les moindres détails afin de créer des cartes uniques en leur genre.

“Après avoir fait les Beaux-arts de Montréal j’ai travaillé pour le ministère des ressources naturelles et je patrouillais sur les rivières jusqu’au jour où j’ai voulu intégrer mon art à mon travail de tous les jours en dessinant et peignant ce que je voyais.”
