The gravitational constant represented by a capital G still a mystery after 100s of years.

When comparing different types of antifouling paints against fouling on leisure boats, the results were the opposite of what many would expect. Of the paints tested, the biocide-free silicone paint worked best, and the paint marketed as environmentally friendly turned out to be extremely toxic. The study, led by Chalmers University of Technology in Sweden, was conducted in Swedish, Danish and French coastal waters and also showed that coatings with a low copper content can be just as...

Novel catalyst design boosts solar-driven ammonia production under mild conditions

Sunlight, water, air and metal-organic catalysts—that could be all it takes. TU Wien has shown how catalyst design can be advanced for solar-driven NH3 synthesis. Without this chemical technology, feeding the world as we know it would be nearly impossible.

Hurricane rainfall and landslide risk are on the rise in Southern California

Climate change could make historically rare tropical storms in Southern California produce significantly more precipitation in the next few decades, and when they strike, landslides are likely to become a bigger risk across the region, according to new research in Nature Climate Change.

Global warming hit 1.37°C in 2025, with Earth accumulating heat at an accelerating rate

Strong and consistent evidence shows that the entire climate system is continuing to heat, driving rapid global warming. Human activities pushed global warming to 1.37°C in 2025, and its level is projected to surpass 1.5°C in about four years. Crucially, the rate at which heat is accumulating in Earth's system suggests high levels of future warming.
