By Mindy Weisberger, CNN (CNN) — Hovering blue flames that flicker over bogs and marshes have inspired ghostly folktales for centuries. Known as “will-o’-the-wisp,” “jack-o’-lantern,” “corpse candle” and “ignis fatuus” (“foolish fire” in Latin), the global phenomenon has a spine-tingling history.

By Katie Hunt, CNN (CNN) — It’s the time of year when leading scientists might not want to let any calls go to voicemail. Prizes in chemistry, physics, and physiology or medicine, established by Swedish industrialist Alfred Nobel more than a century ago, will be announced this week, along with prizes in peace and literature.

By Jacopo Prisco, CNN (CNN) — The search for an unknown planet in our solar system has inspired astronomers for more than a century. Now, a recent study suggests a potential new candidate, which the paper’s authors have dubbed Planet Y. The planet has not been detected but merely inferred by the tilted orbits of

By Amarachi Orie, CNN (CNN) — Ice cream, mascarpone and milk-washed cocktails may sound like simple pleasures — but the ones served at a two-Michelin-starred restaurant in Denmark contained a little extra something: ants. Alchemist in Copenhagen, currently ranked No. 5 on The World’s 50 Best Restaurants list, describes itself as “part science lab” and

By Jackie Wattles, CNN (CNN) — Some 15,000 NASA employees were sent home this week as a government shutdown began, halting work across much of an agency already grappling with budget cuts and widespread job losses. But at least one NASA effort appears to be moving full steam ahead: the Artemis program. With the goal

By Laura Paddison, CNN (CNN) — In the early hours of a late September morning, a container ship called the Istanbul Bridge set sail from China, destined for Europe and laden with cargo — everything from batteries to clothing.

By Christopher Lamb, CNN (CNN) — Pope Leo XIV has called for pressure to be placed on governments to protect the environment as he stressed that damaging the natural world is incompatible with the Christian faith in a speech at a climate conference Wednesday. “We cannot love God, whom we cannot see, while despising his

By Andrew Freedman, CNN (CNN) — While the Trump administration wages war against clean energy, it is now vowing to lease millions of acres of public lands at a discount and spend hundreds of millions of dollars to prop up the most polluting source of electricity: coal. This comes as the administration has restricted new

By Katie Hunt, CNN (CNN) — Scientists have used human skin cells to create fertilizable eggs capable of producing early embryos, an advance that could expand possibilities for fertility treatment, according to new research. The proof-of-concept study, published Tuesday in the journal Nature Communications, involved taking the nucleus, the part of the cell that contains

By Amanda Schupak (CNN) — What do you get when you cross a blue jay with a green jay? That’s not the start of a joke, but the subject of a new study that aims to describe a hybrid bird never encountered before in the wild. The bigger question scientists are puzzling over, though, is
