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, […]
