By Laura Paddison, CNN (CNN) — Many parts of world are predicted to endure “day-zero droughts,” periods of extreme and unprecedented water scarcity, which could happen as soon as this decade in certain hotspots including parts of North America, the Mediterranean and southern Africa, according to a new study. It’s well known that climate change,

By Jackie Wattles, CNN (CNN) — NASA on Monday introduced the 10 people — selected from a pool of 8,000 applicants — who will join the agency’s astronaut corps as it races to return to the moon before attempting an unprecedented crewed mission to Mars. The group includes six women and four men, whom acting

By Ashley Strickland, CNN (CNN) — Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary death of a star, or when it is shredded by a black hole. The observation of repeating

By Gina Park, CNN (CNN) — Sky-gazers should get ready for a full day of celestial events on Sunday, including a partial solar eclipse in parts of the Southern Hemisphere. The partial solar eclipse will peak, the point at which the moon blocks the largest portion of the sun’s surface, at 3:41 p.m. ET. But

By Ashley Strickland, CNN (CNN) — A violent storm may have sent two baby pterosaurs spiraling to their deaths in a lagoon about 150 million years ago, based on a new analysis of the tiny, astonishingly well-preserved fossils. This latest research also provides fresh clues that may unravel a broader enduring mystery surrounding the site

By Andrew Freedman, CNN (CNN) — A record-breaking and astonishingly expansive marine heat wave is underway in the Pacific Ocean, stretching about 5,000 miles from the water around Japan to the West Coast of the United States. The abnormally warm “blob” of ocean water, which is getting a significant boost from human-caused global warming, is

By Katie Hunt, CNN (CNN) — A plan to genetically engineer a version of the dodo, a giant flightless bird that disappeared 400 years ago and became the poster child for extinction, has made some headway, according to Texas-based biotechnology firm Colossal Biosciences. The company’s scientists said they have succeeded in culturing specialized cells from

By Bill Weir, CNN Chief Climate Correspondent It was 1985, and improvised empathy was cool. News reports of families starving to death in drought-stricken Ethiopia were enough to move the lead singer of the Boomtown Rats to assemble a British supergroup to help save them.

By Laura Paddison, CNN (CNN) — This summer scientists drilled deep below the Atlantic Ocean off the coast of northeastern US and tapped into a huge, mysterious reservoir of freshwater — what they discovered could have big implications for a world grappling with an increasingly severe water crisis. The existence of freshwater beneath the Atlantic

By Ashley Strickland, CNN (CNN) — Astronomers have spotted a quasi-moon near Earth — and the small space rock has likely been hanging out near our planet unseen by telescopes for about 60 years, according to new research. The newly discovered celestial object, named 2025 PN7, is a type of near-Earth asteroid that orbits the

By Ella Nilsen, CNN (CNN) — New England, long burdened with some of the nation’s highest electricity costs, is facing a growing energy crisis. Winter cold snaps routinely send utility bills soaring in a region where natural gas fuels most of the grid. Offshore wind was seen as the answer — a long-promised relief for

By Ashley Strickland, CNN (CNN) — Researchers have uncovered an unusual survival strategy in Iberian harvester ants that turns basic biology on its head: The queens can produce eggs that develop into two different ant species. A team uncovered this bizarre reproductive trait while trying to solve the mystery of a missing ant species. Preliminary

By Mindy Weisberger, CNN (CNN) — A clutch of 28 dinosaur eggs found in the Qinglongshan fossil reserve in central China is about 86 million years old, according to scientists who used an “atomic clock” method to date the samples. Researchers said they now hope the eggs, and the technique employed to evaluate their age,
