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 ...
Curiosity is exploring Mars' boxwork terrain, where ridges and hollows may have formed from cementation and erosion. The rover has been documenting rock textures and chemistry, comparing smoother ridge rocks with nodular hollow-edge rocks. Scientists ...
NASA has chosen 10 new astronaut candidates who will train for missions to the Moon and Mars. Their selection represents a powerful blend of talent and ambition, fueling humanity's next great leaps into space.
Primordial magnetic fields, billions of times weaker than a fridge magnet, may have left lasting imprints on the Universe. Researchers ran over 250,000 simulations to show how these fields shaped the cosmic web, then validated the results with ...
AI-powered analysis of routine blood tests can reveal hidden patterns that predict recovery and survival after spinal cord injuries. This breakthrough could make life-saving predictions affordable and accessible in hospitals worldwide.
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 ...
Not drinking enough water could intensify stress responses. Researchers found that under-hydrated individuals had cortisol levels more than 50% higher during stressful situations. Poor hydration didn't make participants feel thirstier, but it did ...
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 ...
