JWST Finds a Galaxy Cluster That Shouldn’t Be This Mature So Early in the Universe

New observations from NASA’s James Webb Space Telescope deepen the mystery of a young but unexpectedly mature galaxy cluster in the early universe that challenges leading ideas about cosmic evolution. A remarkably dense and massive galaxy cluster from a period when such structures were not expected to be so fully developed is putting pressure on […]

Scientists Think Fungi Could Turn Martian Dirt Into Farmland

Scientists from the United States and Brazil are exploring how beneficial fungi could turn Martian and lunar regolith into fertile growing media You’re on the fourth human mission to Mars, and you’ve been tasked with establishing the first self-sustaining food crop on a Martian settlement. You’re nervous because you’re using a new type of fungi […]

Have We Found Alien Life? Here’s What Scientists Really Think

Claims about possible extraterrestrial life on K2-18b and Mars generated worldwide excitement, but a survey of hundreds of astrobiologists found that most experts remained cautious rather than convinced. It may seem like we are on the verge of discovering alien life. In 2025, a press release stated that we have the “strongest hints yet” of […]

Neuroscientist Challenges the Idea That Your Brain “Makes” Decisions

A professor proposes that behavior emerges through continuous interactions among sensory, sensorimotor, and motor processes rather than a dedicated decision-making mechanism. There may be a gap between how people believe decisions are made and what actually happens inside the brain, according to Indiana University professor Tom James. For decades, both scientific theories and everyday thinking […]

Scientists Discover a Hidden Hormone Pathway That Protects the Liver From Damage

GDF15 may protect against liver inflammation and scarring through a newly identified pathway that operates independently of weight loss. A hormone already known for reducing appetite and supporting weight loss may have another important function: protecting the liver from damaging inflammation. Researchers at McMaster University found that GDF15 works through a previously unknown signaling pathway, […]
