Do black holes hide the secrets of their ancestors?

A black hole illustration with two black holes within one. Black holes are monstrous and monolithic regions of space and time that have captured humanity’s imagination. Some are created by the death and collapse of a massive star — yet no single star can birth the most tremendously large black holes. Those are the supermassive […]

NASA is seeking a faster, cheaper way to bring Mars samples to Earth

CAPE CANAVERAL, Fla. (AP) — NASA’s plan to bring samples from Mars back to Earth is on hold until there’s a faster, cheaper way, space agency officials said Monday. Retrieving Mars soil and rocks has been on NASA’s to-do list for decades, but the date kept moving forward, as costs ballooned. A recent independent review […]

World’s coral reefs hit by a fourth mass bleaching event, NOAA says

Extreme ocean heat is causing a mass bleaching event in coral reefs across the globe, according to the National Oceanic and Atmospheric Administration. NOAA on Monday declared that a “4th global coral bleaching event” was taking place and that bleaching had been documented over the last 14 months in every major ocean basin, including off […]

Dinosaurs displayed a fast growth rate from the very beginning

By Will Dunham WASHINGTON (Reuters) – One of the traits that helped make the dinosaurs such an evolutionary success story – thriving for 165 million years – was their fast growth rate, from massive meat-eaters like Tyrannosaurus to immense plant-eaters like Argentinosaurus. But when did this characteristic first appear? A new study indicates it was […]

How climate change could be driving ‘killer’ cold outbreaks in oceans

It’s not just ocean heat that’s affecting marine life – new research shows extremely cold events are welling up and causing mass mortalities. And the same planet-warming pollution that’s driving the climate crisis is likely to blame for these “killer events” on the other end of the temperature spectrum. The world’s oceans have been plagued […]

Coral reefs suffer fourth global bleaching event, NOAA says

By Gloria Dickie and Alison Withers (Reuters) – Along coastlines from Australia to Kenya to Mexico, many of the world’s colorful coral reefs have turned a ghostly white in what scientists said on Monday amounted to the fourth global bleaching event in the last three decades.
