A US appeals court has ruled that most tariffs imposed by Donald Trump are unlawful. The decision delivers a serious setback to his trade policies and points toward a Supreme Court confrontation. The ruling cancels Trump’s “reciprocal” tariffs on dozens of nations. It also invalidates levies imposed on China, Mexico and Canada. Court confirms Congress controls tariffs In a 7-4 decision, the US Court of Appeals for the Federal Circuit ruled the tariffs “invalid as contrary to law”. Judges rejected Trump’s claim that the International Emergency Economic Powers Act gave him authority. They emphasized that only Congress can impose tariffs.…

A global systematic review has revealed that the shingles vaccine may reduce the risk of cardiovascular events in adults. The analysis found that receiving the vaccine was associated with an 18% lower risk of heart attack or stroke, with slightly lower but still significant benefits for adults over 50. The study, the first of its kind worldwide, analyzed data from 19 studies, including randomized controlled trials and observational research. Researchers suggest the protective effect could be linked to reducing inflammation caused by shingles, which is known to contribute to heart and circulatory problems. Experts have welcomed the findings but emphasized…
The United States has cancelled a decades-old tariff exemption that let imports under $800 enter duty-free, altering the retail landscape. Starting Friday, small parcels will face customs inspections and tariffs, affecting millions of shipments daily. Customs data shows that in 2023 nearly 1.4 billion packages worth over $64bn entered the US under the de minimis rule. Analysts warn higher prices, fewer choices, and strain on small businesses. Buenos Aires shoe designer Katherine Theobalds said: “It might be the end for us.” How de minimis shaped trade The de minimis exemption began in 1938 to avoid collecting minor tariffs that were…

Scale of Destruction Across Europe Authorities recorded more than 1,800 wildfires, releasing over 38 million tonnes of CO₂.Only five EU countries — Czech Republic, Estonia, Lithuania, Luxembourg, and Malta — avoided wildfires.Italy and Romania each reported over 450 fires, topping the list.Cyprus recorded just three fires, yet they caused devastating damage.Spain lost more than 400,000 hectares,…
Nvidia has achieved record revenue as artificial intelligence reshapes the technology landscape, despite growing political challenges. On Wednesday, the Santa Clara-based chipmaker reported $46.7bn (£34.6bn) in second-quarter revenue, a 56% increase compared with the same period in 2024. Shares dipped in after-hours trading after executives admitted the company was still “working through geopolitical issues.” Nvidia remains caught in the trade tensions between Washington and Beijing. Frequent US policy shifts under the Trump administration, aimed at maintaining American leadership in artificial intelligence, add further uncertainty for the company. Tech giants drive record growth Nvidia’s processors have become essential to the global…
Sharks may face a future where their vital teeth are weakened, making it harder for them to feed efficiently and potentially destabilizing marine ecosystems. A new study found that ocean acidification, driven by increased CO₂ absorption, could damage shark teeth faster than they are replaced. Shark jaws carry multiple rows of teeth that are constantly replaced, but higher acidity could accelerate erosion, leaving sharks less able to hunt. Researchers tested 60 naturally shed blacktip reef shark teeth in tanks simulating current ocean pH (8.1) and projected 2300 conditions (7.3). After eight weeks, teeth in the more acidic water suffered roughly…
Wild bees actively select flowers that provide a balanced mix of protein, fats, and carbohydrates, according to a new study in the Proceedings of the Royal Society B: Biological Sciences. Ecologists tracked eight species of wild bumblebees in the Colorado Rockies over eight years, mapping their pollen diets and analyzing the macronutrient content of different flowers. Researchers discovered that pollen protein levels varied dramatically, ranging from 17% to as high as 86%. Seasonal changes also played a role: spring flowers tended to be rich in protein, while late-summer blooms offered more fats and carbohydrates. Bees adjusted their diets accordingly, depending…
Jets Handed Over Ahead of Original Plan The U.S. aircraft producer will supply 25 planes to the Irish carrier months earlier than originally arranged. Deliveries of the 737 MAX, first scheduled for next spring, are now set for October, according to Ryanair chief executive Michael O’Leary. He commended Boeing’s performance, calling the aircraft “high-quality,” and voiced confidence that regulators in the United States would grant rapid certification. Boeing’s History of Setbacks The company has faced sustained criticism over flaws in safety and production. The 737 MAX was grounded worldwide following multiple accidents linked to technical issues, including one incident in…
