A new catalyst design could significantly improve the conversion of CO2 into methanol, an important fuel and chemical feedstock. Researchers separated key reaction steps across different catalyst sites, avoiding a long-standing trade-off between ...

What if some black holes aren't black holes at all? A new theoretical study suggests that when a massive star collapses, it might not form a singularity hidden behind an event horizon. Instead, the collapse could trigger the birth of a tiny new ...

Millipedes may have been crawling across Earth's landscapes nearly 460 million years ago, long before vertebrates ventured onto land. A new study finally completes their evolutionary family tree, revealing surprising clues about these ancient ...

Parrots may be doing more than just repeating words--they may actually use names. By analyzing hundreds of recordings from pet parrots, researchers found evidence that many birds use specific names to identify particular people, animals, and even ...

One of the most celebrated claims about Yellowstone's wolves is facing a major challenge. Scientists say the study behind the famous trophic cascade story relied on flawed methods that overstated the ecological impact of wolf recovery. Their ...

A new international study finds that middle-aged Americans are lonelier, more depressed, and experiencing worse memory and health than earlier generations. Researchers say growing financial strain, weaker social supports, and chronic stress may ...

Ancient encounters between humans and the mysterious Denisovans are still shaping people today. By analyzing genomes from populations across the Pacific, researchers uncovered evidence that the ancestors of Near Oceanians interbred with at least ...

A three-year study of nearly 4,000 adults ranging from age 19 to 94 found that brain health can improve at any age, challenging the common belief that mental sharpness must decline as we get older. Participants spent just a few minutes a day on brain ...

A newly identified crocodile species nicknamed "Lucy's hunter" prowled Ethiopia's rivers when Lucy's species walked the Earth more than 3 million years ago. The giant predator was likely the most dangerous animal in the ecosystem and may have ...

Using the Keck Observatory, astronomers measured the spins of dozens of giant planets and brown dwarfs orbiting distant stars. They found that giant planets can spin faster than much more massive brown dwarfs, challenging simple assumptions about ...
