Nanotyrannus: A Separate Species, Not a Young T. Rex
New research confirms that controversial dinosaur fossils belong to a separate species called Nanotyrannus, not juvenile Tyrannosaurus rex, reshaping understanding of tyrannosaur diversity in the Late Cretaceous. The study, led by Nicholas Longrich and Evan Saitta, used growth ring analysis to sh...

AI can't explain its own decisions, study finds
Large language models often fabricate justifications for their decisions, lacking genuine self-awareness and relying on training data patterns instead. Anthropic's research reveals that current AI systems are fundamentally unreliable at introspection, failing to accurately report their own intern...

Drunk Chimps' Urine Tests Confirm Controversial Theory
The "drunken monkey hypothesis" proposes that the human attraction to alcohol evolved from our primate ancestors' ability to locate high-calorie, fermenting fruit. New research on wild chimpanzees in Uganda found alcohol metabolites in their urine, providing direct evidence they regularly consume...

Tiny RNA Molecule Replicates Itself in Lab
Researchers have discovered a remarkably short, 45-nucleotide RNA strand capable of copying itself, providing a tangible model for how early genetic material might have initiated life's complexity. This finding supports the "RNA world" hypothesis, as RNA can both store genetic information and cat...
