Canada Fires Back at US With Sweeping Retaliatory Tariffs

The US imposed 50 percent tariffs on nearly $20 billion worth of Canadian goods this week, and Prime Minister Mark Carney responded by announcing dollar-for-dollar retaliation on US steel, electronics, and other imports starting September 8. Canadian provincial premiers publicly backed Carney's hardline stance, with several declaring that trust in the Trump administration has collapsed entirely. The standoff marks a significant escalation in what has become a sustained trade war between the two largest trading partners in North America, and the September 8 deadline will test whether either side blinks first. Carney's retaliatory package is structured to mirror US measures precisely, a deliberate signaling strategy rather than a negotiating gesture.

Iran Threatens Neighbours Over US Economic War

Iran's newly appointed security chief Mohsen Rezaei publicly warned this week that any neighbouring country joining US efforts to squeeze Tehran's economy would be treated as an enemy, with Iranian retaliation targeting their economic interests. The threat landed as Trump doubled down on his claim that the Strait of Hormuz falls under US territorial jurisdiction — a position that has no basis in international law and has further inflamed tensions. Iraq moved quickly to de-escalate, with its president stating that Iraqi territory would not be used to attack other states, after which Iran granted passage to some Iraqi oil tankers through Hormuz. The episode has reshuffled regional allegiances at speed, with US military refuelling aircraft quietly withdrawn from a Bulgarian base that Iranian officials had reportedly been weighing as a strike target.

Judge Strikes Down Trump's 75-Country Visa Ban

A federal judge ruled this week that the Trump administration's ban on issuing visas to citizens of 75 countries was illegal, finding it discriminated on the basis of nationality in violation of US immigration law. The policy had been justified on the grounds that nationals of those countries were likely to require public assistance — a rationale the court rejected as a pretext for blanket nationality discrimination. The ruling is a significant legal setback for the administration's immigration agenda, though the White House is expected to appeal and may seek emergency stays. The ban had blocked visa processing for citizens of roughly a third of the world's countries simultaneously.

Russia Holds Secret Talks With Unconventional US Envoy

The White House dispatched Rodney Mims Cook Jr. — an architect and Russia enthusiast best known for overseeing Trump's new ceremonial ballroom — to hold secret negotiations with Russian officials in St. Petersburg this week, the Financial Times reported. Putin simultaneously rejected Ukrainian peace proposals in a broadcast interview, warning that Kyiv had opened a "Pandora's box" and threatening its most vulnerable economic sectors. The choice of envoy has baffled diplomatic observers and raised questions about whether the back-channel carries any real mandate or is a gesture designed to signal openness to talks without committing to anything. Cook has no diplomatic background but is known for having built a dacha-style home in the United States.

mRNA Cancer Vaccine Shows Breakthrough Results, Faces US Funding Cuts

A personalised mRNA vaccine designed to train each patient's immune system to hunt and destroy melanoma cells has produced results that oncologists are calling transformative, with trial data showing the treatment can target the deadliest form of skin cancer with a precision no previous therapy has matched. The technology is a direct descendant of the mRNA platform developed for COVID-19 vaccines, now repurposed for oncology. The research is now colliding with sweeping cuts to NIH and FDA budgets under the Trump administration, creating uncertainty about whether US clinical trials can continue at their current pace. Thousands of patients — including in Europe — are waiting on expanded trial access.

Chinese Humanoid Robot Breaks Usain Bolt's 100m Record

A Chinese humanoid robot completed 100 metres in 9.39 seconds at an international humanoid games competition this week, surpassing Usain Bolt's standing world record of 9.58 seconds set in 2009. The feat was achieved on a standard athletics track under timed conditions, marking a milestone in bipedal robotics that engineers have been working toward for years. The result signals that humanoid locomotion has crossed from the laboratory into territory where machines can outperform the peak of human athletic capacity in straight-line speed, raising both excitement and pointed questions about what comes next. The competing robot was developed by a Chinese team whose identity and institutional affiliation have not been fully disclosed.

Sudan's Kordofan Crisis Displaces 200,000 More People

Intensified fighting in Sudan's Kordofan region has displaced at least 200,000 people since late last year, with thousands more fleeing this week toward the relative safety of El Obeid as Rapid Support Forces and army units continue to clash across the area. The humanitarian corridor into El Obeid is itself under strain, with aid organisations warning that the city cannot absorb continued mass arrivals. Sudan's civil war, now well into its second year, has produced one of the world's largest displacement crises with almost no sustained international diplomatic attention. Meanwhile, in Khartoum, residents are attending an open-air cinema that has reopened as an act of cultural defiance amid ongoing conflict.

Israel Strikes Syria Without Alerting Washington

Israel carried out strikes on a Syrian military base this week without giving the United States advance notice, prompting a rare public rebuke from US envoy Tom Barrack, who said Washington had not been adequately warned — a claim Israeli officials denied. The strikes came as Israel also continued operations in the West Bank, where settlers and military units injured multiple Palestinians and Israeli construction bids opened for new housing units in occupied territory. The Syria episode has exposed genuine friction between Washington and Tel Aviv over operational coordination, even as the broader US-Israel alliance remains intact. A separate Israeli strike near Damascus drew condemnation from Syria's new government, which called it a violation of international law.

Hawaii Hit by Second Storm in a Week

Tropical Storm Moke advanced toward Hawaii's Big Island this week carrying heavy rain and strong winds, arriving just days after Hurricane Lala had already inflicted significant damage on the same region. The National Weather Service warned of serious flooding and mudslide risk, particularly in areas where Lala had already stripped vegetation and saturated soils. Two major storms striking the same island chain within a week is highly unusual and has prompted renewed scrutiny of whether the eastern Pacific storm season is intensifying beyond historical norms. Emergency services were still responding to Lala damage when Moke's approach forced a second round of evacuations.

H5 Bird Flu Reaches Australian Mainland Mammals

A long-nosed fur seal found dead at Beachport on South Australia's Limestone Coast has tested positive for H5 bird flu, becoming the first confirmed case of the virus killing a mammal on the Australian mainland. Australia's environment minister warned the death presages "significant losses" as the strain continues its global spread into new species and geographies. Scientists are monitoring whether the virus has begun circulating in Australian marine mammal populations, which would represent a major escalation in the country's exposure to a pathogen that has already killed millions of seabirds and thousands of marine mammals worldwide. The seal was found dead on Wednesday.
