Nvidia, the world’s top maker of AI chips, is facing fresh trouble. The United States has just announced strict new rules. These rules stop Nvidia from selling one of its key AI chips, the H20, to customers in China—unless it gets a special license. As a result, Nvidia may lose up to $5.5 billion from blocked sales. The move is part of a growing tech war between the U.S. and China. Both countries want to lead the future of artificial intelligence. Now, the U.S. is tightening its grip on the supply chain for powerful computer chips. Why Nvidia Matters in…

The trade conflict between the United States and China is taking a serious turn. Beijing is now limiting exports of rare earth elements—critical materials used in technology and defense. Instead of just tariffs, China is using its control over these minerals as a powerful weapon. The move has revealed just how dependent America is on China for these materials. In response, the U.S. government is trying to produce more rare earths at home. President Trump has asked the Commerce Department to fix this problem fast. But why are these rare earths so important, and what could happen next? Rare Earths:…

Scientists at the University of Cambridge have made a new discovery that could point to life on a distant world. Using the powerful James Webb Space Telescope, they found signs of gases in the atmosphere of planet K2-18b. These gases, on Earth, are made only by living microbes. While the evidence is not final, the findings are stronger than ever before. Researchers say this may be our clearest sign yet that we are not alone in the universe. Strange Gases Hint at Possible Life K2-18b is about 2.5 times the size of Earth and orbits a star 700 trillion miles…

Your reaction speed can reveal important details about how your body’s systems, especially your brain and nervous system, are functioning. As we grow older, our reaction times naturally decrease, and this change often starts becoming noticeable in our 30s. Scientists now believe that maintaining an average reaction speed is a good sign that your brain is still working properly. But reaction times reveal more than just how sharp your mind is—they also offer clues about heart health, your risk of falling, and even early signs of conditions like dementia. Simon Cox, a brain and aging expert from the University of…

President Donald Trump has escalated his feud with Harvard University, calling for the revocation of its federal tax-exempt status following a freeze on over $2 billion in federal funding. This move came after Harvard rejected new government directives aimed at addressing antisemitism on its campus. The ongoing dispute highlights a growing tension between the federal government and elite universities over academic freedom, political expression, and government influence. Trump Targets Harvard’s Financial Benefits In a series of statements made on social media, Trump warned that Harvard’s tax-exempt status could be stripped if the institution continued to promote what he described as…

President Donald Trump often blames past trade deals, like the North American Free Trade Agreement (NAFTA), for the decline in American factory jobs. In a speech on April 2, Trump said that steelworkers, farmers, and skilled workers suffered greatly under these agreements. He also claimed that foreign competitors wrecked American manufacturing and hurt the country’s economy. Trump believes a 25% tariff on all imported vehicles will boost prices and lead to a rise in new factories across the United States. But experts say the situation is more complicated than that. Many Factors Behind Job Losses Auto job losses, especially in…

As technology becomes a regular part of daily life, researchers are exploring how it affects aging minds. A new study published in Nature Human Behavior brings a fresh perspective to this question. It looked at how digital tools like smartphones and computers might help protect older adults from cognitive decline. Researchers from the University of Texas at Austin and Baylor University conducted a large review of past studies. They wanted to see if the idea known as the “digital dementia hypothesis” holds true. This hypothesis suggests that using digital devices too often could hurt brain health over time. However, the…

Powerful winds swept through Beijing and northern China on Saturday, forcing airports, subways, and tourist sites to shut down. The intense windstorm disrupted the lives of millions and marked the most severe event of its kind in over half a century. By 11:30 a.m. local time, officials had canceled 838 flights at Beijing Capital International Airport and Daxing International Airport, according to a report by Reuters. Train lines were also suspended, including the airport express subway and several high-speed routes connecting major cities. The storm, fueled by a cold air mass from Mongolia, brought wind gusts reaching up to 93…

Ukrainian President Volodymyr Zelensky has invited former U.S. President Donald Trump to visit Ukraine before considering any peace talks with Russia. He stressed the need to see the suffering and destruction firsthand. This plea came shortly before a deadly missile strike in the city of Sumy on Sunday, which killed 34 people and injured over 100. The attack, one of the deadliest this year, sparked global condemnation and renewed calls for justice and peace. Zelensky’s Plea to Trump: Witness the Reality In a televised interview recorded prior to the Sumy attack, Volodymyr Zelensky directly appealed to Trump.“Before any decision or…

Seasonal allergies are becoming more intense as higher temperatures stretch out pollen seasons, making episodes like thunderstorm asthma more common. Scientists warn that climate change is making allergies worse by increasing pollen levels and the severity of allergic reactions. Thunderstorm Asthma: A Deadly Health Crisis Many people enjoy watching storms as they develop, but inside these clouds, a biological storm is brewing. Thunderstorms can absorb large amounts of pollen and break it down into smaller particles through rain, lightning, and humidity. Once these pollen fragments fall back to the ground, people unknowingly breathe them in, which can trigger severe allergic…
