Scientists have uncovered a crucial weakness in the malaria parasite that could open the door to new treatments. Researchers identified a protein called Aurora-related kinase 1 (ARK1) that acts like a traffic controller during the parasite's unusual ...

Iron Age teeth from southern Italy have become time capsules, preserving intimate details of childhood and diet. Growth lines in the enamel reveal moments of early-life stress, while hardened plaque holds microscopic remains of cereals, legumes, and ...

Northern wildfires may be more dangerous for the climate than they appear. Researchers found that fires in boreal forests can burn deep into peat soils, releasing ancient carbon stored for hundreds or thousands of years. These slow, smoldering fires ...

Returning rescued slow lorises to the wild may sound like a conservation success, but a new study shows it can turn deadly. Researchers tracked nine released animals and found that only two survived, with most killed in territorial attacks by other . ...

Japanese snow monkeys don't just soak in hot springs to escape the winter chill -- their steamy spa sessions may also be reshaping their invisible world. Researchers in Japan found that macaques who regularly bathe show subtle but intriguing ...

In Yellowstone's wild chess match between wolves and cougars, it turns out the real power play is theft. After tracking nearly a decade of GPS data and thousands of kill sites, researchers found that wolves often muscle in on cougar kills--sometimes ...

A famously resilient bacterium may be tough enough to survive one of the most violent events imaginable on Mars. In laboratory experiments designed to mimic the crushing shock of a massive asteroid impact, researchers squeezed Deinococcus radiodurans ...

Fusion energy may be one of the most promising clean power sources of the future--but only if scientists can precisely measure the extreme, fast-moving plasmas that make it possible. A new U.S. Department of Energy-sponsored report urges major ...

Earth's vertebrate diversity may be far richer than anyone realized. A sweeping analysis of more than 300 studies suggests that for every known fish, bird, reptile, amphibian, or mammal species, there are about two nearly identical "cryptic" species ...

Tiny, tooth-sized fossils have just reshaped the story of our deepest ancestry. Paleontologists have discovered the southernmost remains ever found of Purgatorius--the earliest-known relative of all primates, including humans--in Colorado's Denver .. ...
