A study found that people judged artificial intelligence to be less conscious than humans even when the systems behaved like people. Participants assessed AI and humans more similarly when asked about awareness rather than consciousness.

Astronomers found that a scorching planet 320 light-years away has a chemical composition closely resembling that of its host star. The result provides direct evidence for a core model of planet formation and could improve predictions about the composition of distant rocky worlds.

Researchers identified a 210-million-year-old dinosaur from Zimbabwe that points to a distinct prehistoric ecosystem in southern Africa. The fossil suggests that regional climate differences separated dinosaur populations and helped produce species found nowhere else.

Researchers found that cellular recycling activity during aging does not consistently indicate healthier cells and may sometimes correlate with poorer physical condition. A small study suggests that gentle exercise can shift this recycling system toward patterns associated with younger cells.

A 165-million-year-old fossil of Megacauda sungei reveals a small aquatic predator with specialized teeth and an advanced swallowing system. Its anatomy may represent an early step toward the mammalian adaptations that made safe milk nursing possible.
