Rice, a staple for billions, is one of the most resource-hungry crops on the planet--but scientists may have found a way to change that. By applying nanoscale selenium directly to rice plants, researchers dramatically improved nitrogen efficiency, .. ...

Diamonds hitch a ride to the surface through explosive kimberlite eruptions, powered by volatile-rich magmas. New simulations show that carbon dioxide and water are the secret ingredients that make these eruptions possible.

Researchers found that magic mushrooms and fiber caps independently evolved different biochemical pathways to create psilocybin. This convergence shows nature's ingenuity, but the reason why remains unknown--possibly predator deterrence. Beyond ...

South African diamonds have revealed nickel-rich metallic inclusions, offering the first direct evidence of reactions predicted to occur deep in Earth's mantle. The study shows how oxidized melts infiltrated reduced rocks, trapping both the cause and ...

Gifted dogs can categorize toys by function, not just appearance. In playful at-home tests, they linked labels like "fetch" and "pull" to toys--even ones they'd never seen before. The findings hint that dogs form mental concepts of objects, much like ...

Researchers have shown that stress and retrovirus levels are tightly linked to disease in koalas. High KoRV loads make koalas more vulnerable to chlamydia, worsening epidemics in stressed populations. Protecting habitats, careful breeding, and ...

A 95-million-year-old crocodyliform fossil, affectionately nicknamed Elton, was discovered in Montana by student Harrison Allen. Unlike most crocs, it lived on land and ate a varied diet. The find led to the naming of a new species, Thikarisuchus ...

By recording grouper grunts for 12 years, scientists discovered major shifts in how red hind spawn and compete. Courtship calls once dominated, but territorial sounds have surged, suggesting changes in population structure. Machine learning helped .. ...

For more than a century, a dazzling pink-and-yellow moth was mistaken for a common European species, but DNA analysis revealed it as entirely new: Carcina ingridmariae. Found across the eastern Mediterranean, this hidden beauty had evaded recognition ...

A long-term study in Colorado reveals that insect populations are plummeting even in remote, undisturbed areas. Over two decades, flying insect abundance dropped by more than 70%, closely linked to rising summer temperatures. The results suggest that ...
