Trump pauses new tariffs on Canada for three days as countries move toward trade deal

Background

China has long relied on Microsoft's Windows operating system in its government agencies. Now Beijing is moving to reduce its use of US technology. The Chinese Ministry of State Security has ordered state agencies to switch away from Windows.

What happened

Government officials told state agencies to uninstall Windows 10 from their computers. They must move to domestic systems based on Linux instead. Bloomberg reported this shift is happening a few months earlier than originally planned.

Why it matters

For most people outside China, this shows countries are building their own tech systems. China's move may prompt other nations to do the same. It reflects growing tension over US technology and global supply chains.

Background

Sarah Wynn-Williams worked at Facebook (now Meta) as a director of public policy. She left the company and wrote a memoir called Careless People. It came out on March 11, 2025.

What happened

The book is highly critical of Facebook's choices during Wynn-Williams' time there. She accuses the company of contributing to the Rohingya genocide in Myanmar. She also says CEO Mark Zuckerberg tried to censor content for the Chinese government. Wynn-Williams names other executives, including Sheryl Sandberg and Joel Kaplan, as part of these choices.

Why it matters

This memoir offers a rare inside look at how one of the world's largest social media companies makes decisions. It shows how tech companies can affect real-world crises and governments.

Background

Unitree Robotics is a Chinese company that makes humanoid robots. These are machines built to look and move like humans. The firm just went public on Shanghai's Star Market, a tech-focused stock exchange. This listing marks a big moment for China's push to lead the global robotics industry.

What happened

Unitree made its stock market debut on Wednesday in Shanghai. Its shares opened at 1,100 yuan, then fell to around 900 yuan. Early trading saw shares jump more than 600% in value. The US and China are competing hard to dominate the global robot market.

Why it matters

A successful IPO signals that investors believe in Chinese robotics tech. This debut may speed up development and competition in a field that shapes manufacturing, automation, and future jobs. For most people today this changes little. But it shows where the next wave of robots will come from.

Background

Inflation measures how fast prices rise for goods and services. The UK tracks it monthly through the Office for National Statistics. In July, inflation hit 2.9%, up from 2.6% in June. The jump came as energy prices spiked due to the Iran war disrupting global oil and gas markets.

What happened

On July 1, the UK regulator Ofgem raised the price cap on household gas and electricity by 13%. This added about £221 a year to a typical household's bill. The increase was the largest rise in gas prices in almost four years. It pushed overall inflation to 2.9% in July, the highest rate since March.

Why it matters

Higher energy bills hit household budgets when money is already tight. This is the sharpest summer energy increase in four years, meaning families will pay more to heat and power their homes through the rest of the year. For the government, which promised to give households breathing room, the spike shows how global events like the Iran war can undo progress on cost of living relief.

Background

The US and Canada have been negotiating a trade deal. Tariffs are taxes on imports. Trump had planned to place a 50% tax on about $20 billion of Canadian goods starting Wednesday. Norm covered these escalating talks yesterday as the deadline approached.

What happened

Trump announced Tuesday evening he would delay the tariffs for three days. This pause came less than two hours before the taxes were set to begin. Canadian Prime Minister Mark Carney said "substantial progress" had been made toward a deal. Both sides now have time to finish their agreement.

Why it matters

The delayed tariffs affect everyday goods Canadians sell to the US, from wine to hockey sticks. Without this pause, US prices for those imports would have jumped. The three-day window lets negotiators reach a full deal and avoid costs for American shoppers and businesses that buy Canadian products.

Background

Donald Trump is the US president. Jon Ossoff is a Democratic senator from Georgia running for re-election. Mark Kelly is another Democratic senator and a military veteran. The two sides have been feuding publicly.

What happened

During a campaign event in Georgia on Tuesday, Ossoff called Trump a "draft-dodging, crook president." He was defending Kelly against Trump's criticism. Ossoff said Trump tried to imprison Kelly, who "embodies American heroism." Ossoff also criticized Trump for starting a war he cannot win.

Why it matters

This feud shows the intensity of conflict between the White House and Senate Democrats. How leaders talk about each other in public affects the tone of national politics. Ossoff's sharp language escalates the battle over who is fit for office.

Background

The Trump administration created a task force to combat antisemitism at universities. It investigated Ivy League schools like Harvard, Yale, and Columbia. These schools were examined over their handling of antisemitic speech and conduct.

What happened

A former Justice Department lawyer filed a whistleblower complaint. The lawyer says the task force pushed universities to settle cases. This happened even though investigations were rushed, incomplete, or found no legal violations.

Why it matters

How federal agencies enforce discrimination rules shapes what standards universities must follow. Unfair enforcement can undermine trust in government investigations. It also affects what consequences schools actually face for breaking the rules.

Background

Russia invaded Ukraine over four years ago. Since then, Ukraine has carried out drone attacks on Russian territory. This week brought one of Ukraine's biggest drone attacks yet.

What happened

Ukrainian forces fired almost 800 drones at the Moscow region. The attack came just two days after a prior strike. Russian missiles hit a Ukrainian village, killing 10 people.

Why it matters

The scale of Ukraine's drone strikes shows it can reach deep into Russian territory. These attacks may affect how the war unfolds. Civilian deaths in Ukraine continue as Russia strikes back.

Background

Mykhailo Fedorov served as Ukraine's defence minister until his unexpected firing last month. The dismissal sparked protests. Ukraine has been under martial law since Russia's invasion in February 2022, which suspends elections.

What happened

Fedorov released a video Tuesday calling for wartime presidential elections. He said Ukraine must restore full democracy even during prolonged war. Fedorov did not name Zelenskyy but implied criticism of the current president.

Why it matters

This is the boldest challenge to Zelenskyy's rule since the invasion began. It shows disagreement inside Ukraine's government over whether one leader can rule without facing voters during wartime. Many see it as a sign that some officials believe democracy matters even while fighting.

Background

Syria has nuclear material left over from the Assad era, a period under former president Bashar al-Assad. The International Atomic Energy Agency, or IAEA, is the UN body that checks nuclear material worldwide to stop weapons use. Last month, Syria told the IAEA about a site with this material that had not been reported before.

What happened

IAEA inspectors found several tons of nuclear material at the undisclosed Syrian site. Rafael Grossi, the IAEA's head, said the material could be misused. Syria's government reported the site on July 17 and praised their decision as courageous. The material will now be placed under international safeguards.

Why it matters

International oversight means inspectors can watch this material and verify it stays safe. Nuclear material that is not tracked raises concerns about misuse. Syria's disclosure helps prevent possible risks from loose nuclear resources in the region.

Background

The US and South Korea hold annual joint military drills called the Ulchi Freedom Shield exercise. These drills test how the two militaries work together to prepare for conflict. The exercise began Monday and was originally scheduled to run through August 27.

What happened

South Korea's military announced Wednesday that the drills will end six days early, on Friday, August 21. The US requested the change. Separate field training exercises will also be reduced in scale, though officials are still working out those details.

Why it matters

These drills are routine for South Korea's defense. Changes to them signal shifts in US strategy toward the region. Donald Trump ordered the Pentagon to scale back the exercises, citing his relationship with North Korea's leader Kim Jong Un. The cuts reflect a policy move toward talks rather than military posturing.

Background

Four states filed a lawsuit against Meta. They argue that Facebook and Instagram harm children. The case went to trial this week.

What happened

A federal trial started Tuesday. Four states presented their case against Meta. They claim the company's social media platforms hurt children through features like endless scrolling and algorithms designed to boost engagement.

Why it matters

Many parents worry about how social media affects their kids. This trial could shape how platforms design their apps. A court ruling might force Meta to change features millions of young people use every day.

Background

London introduced an ultra-low emission zone, or Ulez, in 2019. This policy bans the most polluting vehicles from entering the city. The goal was to improve air quality. Critics complained it would burden drivers.

What happened

Researchers studied over 3,400 primary school children in London and Luton. They measured lung function before and after Ulez started. Children in London showed lung growth that had been slowed by pollution. After the zone took effect, their lungs grew bigger and stronger.

Why it matters

Air pollution harms how children's lungs develop. This study shows that reducing traffic pollution can reverse that damage. It suggests clean air zones in other cities could help children breathe easier and grow healthier.

Background

Cosmologists want to understand the universe's earliest history. The cosmic dark ages are a period roughly 150 million years after the Big Bang. Before the universe's first stars appeared, this period shaped how stars and galaxies formed. An international team led by the University of Cambridge is building a small satellite called CosmoCube to detect signals from this ancient time.

What happened

CosmoCube is a UK-developed satellite, about the size of a small carry-on suitcase. The team will place it on the far side of the Moon. From there, it will listen for a faint signal called the 21-centimetre line. This whisper comes from hydrogen atoms in the early universe.

Why it matters

Understanding the cosmic dark ages helps explain how the first stars and galaxies formed. This history shaped everything we see today, including our own existence. By using the Moon as a shield, CosmoCube can block Earth's radio noise. This lets it pick up signals too faint to hear from Earth.
