The United States is banning imports of some Canadian dairy, most alcohol categories, and motorcycles, sharply escalating a trade war that had until now moved almost entirely through tariffs. Prime Minister Mark Carney called the outright bans "a new phase" and said Ottawa was drafting matching product-level restrictions on US exports.

The move follows Canada's $27.6 billion retaliatory tariff round earlier this week and comes as Trump publicly pressures Canadian companies with US operations to relocate south of the border. Canadian producers of the affected goods are already telegraphing plant closures and export-diversion decisions to Asian and European buyers.

American forces destroyed five more Iranian oil tankers in the Gulf overnight, hours after Iran fired missiles at a US Navy warship in the strait. It was the fastest US-Iran exchange since the war began, and Brent crude touched $100 a barrel for the first time since July on the news.

Pentagon officials said the strikes came under standing rules-of-engagement authority tied to protection of US vessels, and that no US personnel were injured in the initial missile attack. Iranian state media confirmed the tanker losses but disputed the sequence, describing the US strikes as an unprovoked escalation.

A daytime Russian drone attack on Kyiv struck a television channel building on Tuesday and killed at least five people. It was one of the boldest hits on the capital in months, and President Volodymyr Zelensky called it a "new page in Russian degradation," singling out the daylight timing as deliberate.

The strike lands as Western capitals argue over how quickly to send fresh air-defense batteries and long-range munitions. Ukrainian officials say strikes on media infrastructure fit a pattern of chipping at civilian morale ahead of what forecasters expect will be another brutal winter of energy attacks.

A tech failure at UK air traffic control canceled more than 1,000 flights Tuesday, stranding tens of thousands of passengers on one of the busiest travel days of the fall season. Officials said full service will be restored by Wednesday morning as airlines scramble to reposition planes and crews.

Tung Chee-hwa, the shipping magnate who became Hong Kong's first chief executive after the 1997 British handover, has died at 89. His tenure covered the SARS epidemic, the Asian financial crisis, and the earliest post-handover struggles between Beijing and Hong Kong's democracy movement.

German authorities have arrested a suspect tied to a string of attacks on electricity substations, with investigators saying the individual claimed responsibility in written letters. The case sharpens European anxieties about critical-infrastructure sabotage after a year of unexplained cable cuts and pipeline incidents.

After losing in two courts and winning in a third, Missouri officials say they will press ahead with a redrawn congressional map designed to help Republicans. The whiplash leaves candidates, election workers, and voters unsure which district lines will govern the 2026 vote.

Former Senator John E. Sununu won the Republican Senate primary in New Hampshire, setting up a general election to replace retiring Democrat Jeanne Shaheen. It is one of a handful of races that could decide control of the US Senate in November.

The Social Security Administration pledged to resume providing basic data needed to process compensation claims from 9/11 responders and survivors, after months of holdups. Lawyers say the delays have stalled payouts for people who are sick and dying from exposure to Ground Zero debris.

Marvell Technology CEO Matt Murphy said customer trust in custom-silicon roadmaps has fueled the chipmaker's 241% run over the past year. The company has become a quieter beneficiary of the hyperscaler capex boom that keeps Nvidia in the headlines.

Oracle shares climbed as analysts declared "OpenAI is turning things around," a helpful line for a database giant with significant infrastructure exposure to ChatGPT's creator. The rebound in AI ecosystem sentiment is showing up across the second-tier cloud names.

Adani Enterprises shares jumped after its airport unit struck a deal to raise up to $1 billion. Investors including Temasek and BlackRock are reportedly backing the fundraise to fund airport expansion.

Stop losing deals you should be winning.

Bad leads. Slow deals. Objections you didn't see coming.

That's not a sales problem. You're selling to the wrong people.

Most founders never stop to define exactly who their product is actually for. So they pitch everyone, convert few, and wonder why the funnel's broken.

Apple's launch event lands today under new CEO John Ternus, and Xiaomi and Huawei are racing to get their own hardware out first. Chinese manufacturers have shipped foldables for years, giving them a head start Apple must now answer in a maturing phone market.

MIT engineers have engineered bacteria to behave like transistors, producing printable "living circuit boards" grown in a Petri dish. The work opens a path to biological computing devices that could sense chemicals or detect disease inside the body.

A decade-long randomized trial found that implantable cardioverter-defibrillators could benefit patients under 70 with mild-to-moderate heart dysfunction and cardiac scarring. The results could widen eligibility for a device that current guidelines reserve for sicker patients.

Frances Tiafoe came back from two sets down to beat Alex Michelsen 5-7, 3-6, 7-5, 6-3, 7-6 (6) and reach his third US Open semifinal in five years. He will face the winner of Carlos Alcaraz versus Ben Shelton in the last four.

The College Football Playoff has triggered an exclusive 30-day window to negotiate expanding the field to 24 teams, with a December 1 deadline to lock changes in for the 2027 season. It would be the second expansion in three years for a format that only recently moved to 12.

San Francisco starting defensive tackle Alfred Collins tore his patellar tendon in Tuesday's practice in Australia and will miss the entire 2026 season. It is a brutal blow to a 49ers front already thin on interior depth heading into Week 1.

What it is: A quiet argument among climate scientists this summer has spilled into public view, with growing evidence that global warming may be running ahead of what standard models predicted just a few years ago. Recent observations are forcing researchers to ask whether the unusual warmth is temporary noise or an early signal of a more persistent shift.

The detail: The spark was an online row over this summer's brutal heatwaves, which ran hotter and longer than the statistical baselines said they should. Ocean surface temperatures have stayed at record or near-record highs for more than two years, and satellite readings show Earth is absorbing more energy than it radiates back into space — the so-called "energy imbalance" — at roughly double the rate seen two decades ago. Researchers are still fighting over whether reduced sulfur pollution from cleaner shipping fuel, shifts in cloud cover, or a genuine change in climate sensitivity is driving the anomaly. Separating those effects matters because each explanation implies a different trajectory for temperatures over the coming decade.

Why it matters: If the acceleration is real and sustained, then the carbon budgets underpinning the Paris Agreement's 1.5°C target are smaller than governments have assumed, and impacts such as sea-level rise, crop stress, and extreme weather arrive sooner than current plans expect. Insurers, farmers, and coastal cities all price risk off climate projections that may already be out of date.

What to watch: Look out for updated attribution studies this autumn, along with fresh reanalyses of the Earth energy imbalance data that started the fight. The IPCC's next assessment cycle will have to decide whether recent observations justify tightening its central estimates of how fast the planet warms per ton of carbon emitted. Another year of exceptional ocean and atmospheric temperatures would make the acceleration argument substantially harder to dismiss as a short-lived anomaly.
