On Wednesday, the Santa Clara-based chipmaker reported $46.7bn (£34.6bn) in revenue for the second quarter, a 56% increase from the same period in 2024.

Frequent policy shifts from the Trump administration, aimed at keeping the US ahead in artificial intelligence, create further uncertainty for the company. Rising…

A new study warns that ocean acidification could erode shark teeth, leaving the predators less able to feed effectively and potentially destabilizing marine ecosystems. Researchers found that shark teeth exposed to projected future ocean pH levels suffered double the damage compared with today’s conditions, showing increased corrosion and dulled serrations. Ocean acidification, driven by rising CO₂ emissions, could lower average pH from 8.1 to 7.3 by 2300. The study, led by Maximilian Baum of Heinrich Heine University, tested 60 naturally shed teeth from blacktip reef sharks and found accelerated erosion under acidic conditions. While sharks might adapt by replacing teeth…

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…
