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 Film Dolphins Using Seashells As Hunting Tools
A dolphin rises from the water carrying an empty seashell in its jaws, but the shell is not empty for long. Inside, a trapped fish is about to become dinner. An unusual hunting strategy, known as shelling, involves dolphins trapping fish inside empty seashells, carrying the shells to the surface, and shaking out the water […]
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, […]
