A US appeals court has ruled that most tariffs imposed by Donald Trump were unlawful. The decision delivers a sharp setback to his trade agenda and sets up a likely Supreme Court confrontation. The judgement invalidates Trump’s “reciprocal” tariffs targeting dozens of countries. It also blocks levies against major partners such as China, Mexico and Canada. Judges deny Trump tariff powers In a 7-4 ruling, the US Court of Appeals for the Federal Circuit declared the tariffs “invalid as contrary to law”. The judges rejected Trump’s reliance on the International Emergency Economic Powers Act. They stated that the authority to…

A landmark global study has found that the shingles vaccine may do more than prevent the painful rash caused by the herpes zoster virus — it could also reduce the risk of major cardiovascular events. According to the world’s first systematic review and meta-analysis on the subject, adults who received the vaccine were 18% less likely to suffer a heart attack or stroke, with the protective effect particularly evident in older age groups. Researchers analyzed data from 19 studies, including randomized controlled trials and observational research, and presented their findings at the European Society of Cardiology’s annual congress in Madrid.…

The United States has ended a decades-old tariff exemption that helped fuel trade in low-cost goods. From Friday, imports valued at $800 or less will no longer be duty-free and will face stricter customs checks. The move will impact millions of packages every day. In 2023, nearly 1.4 billion parcels worth more than $64bn entered the US duty-free under the de minimis rule. Experts warn the change will hit small businesses hardest and push prices higher, leaving shoppers with fewer options. “I’ve reached the point of acceptance, but when I first heard the news, I thought it could end my…

Nvidia continues to surge as worldwide demand for artificial intelligence grows, even as international disputes threaten its progress. On Wednesday, the chip designer reported revenue of $46.7bn (£34.6bn) for the second quarter, up 56% compared with the same period last year. Despite the strong earnings, shares dipped in after-hours trading after executives admitted the company was still “working through geopolitical issues”. Nvidia remains caught in the escalating trade conflict between Washington and Beijing. Shifting US policies under the Trump administration, designed to protect America’s lead in artificial intelligence, add more pressure on the firm’s outlook. Chip demand fuels rapid expansion…

A new study warns that ocean acidification could weaken sharks’ teeth, threatening their ability to hunt and disrupting marine ecosystems. Researchers tested blacktip reef shark teeth in artificial seawater tanks mimicking current and future projected pH levels. After eight weeks, teeth exposed to more acidic water (pH 7.3) showed double the damage compared with those in today’s conditions (pH 8.1), including increased root corrosion and altered serration. The findings suggest that sharks may struggle to feed efficiently if tooth damage outpaces natural replacement rates. While sharks might adapt by accelerating tooth growth or repair, the study highlights acidification as an…

Wild bees actively manage their diets by visiting different flowers to balance their intake of protein, fat, and carbohydrates, according to new research. Ecologists studying eight species of bumblebees in the Colorado Rockies over eight years mapped the nutritional content of pollen and tracked which flowers the bees preferred. The findings, published in the Proceedings of the Royal Society B, revealed that bees adjust their foraging to meet changing dietary needs, both across species and throughout the seasons. The research team discovered striking differences in pollen composition: some flowers contained as little as 17% protein, while others had up to…

Delivery Timeline Accelerated The U.S. aircraft manufacturer will supply 25 planes to the Irish budget carrier earlier than originally planned. Instead of next spring, the 737 MAX jets are now scheduled to be delivered in October, Ryanair CEO Michael O’Leary said on Wednesday.

Continued Challenges for Boeing Boeing has long faced scrutiny over safety and production issues.
