Rocks formed immediately before and after non-avian dinosaurs went extinct are strikingly different, and now, tens of millions of years later, scientists think they’ve identified the culprit—and it wasn’t the Chicxulub asteroid impact. In a study published Monday in the journal Communications Earth & Environment, researchers argue that dinosaurs physically influenced their surroundings so dramatically that their disappearance led to …

Scientists have warned that research into “mirror life” organisms — hypothetical life forms made up of molecules that perfectly mirror those found in regular life — should be stopped. Theoretically, it’s a cool idea. But some scientists are worried that these life forms, if they’re ever realized, could turn into a major risk for the world around us by turning into an …

The quest for dodo’s de-extinction has gathered steam again. Colossal Biosciences has announced a significant breakthrough in its attempts to bring the flightless bird back to life, 300 years after it became extinct. The Texas-based company has grown pigeon primordial cells for the first time; they are also regarded as precursor cells to sperm and eggs. Announcing this breakthrough on …

Processes occurring deep within the Earth could be responsible for our planet’s changing gravitational field, according to new research that scoured orbital data for clues to the mystery. The shift occurred nearly two decades ago, between 2006 and 2008, but went unnoticed at the time. Only through a recent reexamination of the data were scientists able to detect gravitational variations …

A recently discovered enormous source of niobium — a metal that’s essential for much of today’s technology — appears to have formed when the supercontinent Rodinia ripped apart around 830 million years ago, according to a new study. The niobium-rich carbonatites, which could be one of the world’s largest sources of the metal, have come from deep within the Earth’s …

Tucked away in a lab near Paris, scientists at the Apollon facility have quietly secured a world record: the most powerful laser ever fired on Earth. Operating at a staggering 10 petawatts, Apollon has set a benchmark that global competitors, including the United States, are scrambling to catch up with. Backed by the École Polytechnique, the National Centre for Scientific …

A trio of missions are on track to intercept and study the near-Earth asteroid Apophis during its close encounter with our planet in 2029. The 1,100-foot-wide (340 meters) asteroid Apophis is set for a close but non-threatening brush with Earth on Friday, April 13, 2029, and agencies across the world are looking to make the most of this unique opportunity. …

A massive asteroid nearly the size of a New York skyscraper will make a close approach, or pass, by Earth in the early hours of Sept. 18, according to scientists. They say the asteroid, officially dubbed “2025 FA22,” is set to race past the planet at more than 24,000 mph, and will do so again in 2089 and 2173. The …
