Scientists are uncovering a surprising way to influence bacteria--not by killing them, but by changing how they communicate. Researchers studying oral bacteria found that disrupting chemical signals used in bacterial "conversations" can shift dental ...

Giant mosasaurs, once thought to be strictly ocean-dwelling predators, may have spent their final chapter prowling freshwater rivers alongside dinosaurs and crocodiles. A massive tooth found in North Dakota, analyzed using chemical isotope techniques ...

Consciousness evolved in stages, starting with basic survival responses like pain and alarm, then expanding into focused awareness and self-reflection. These layers help organisms avoid danger, learn from the environment, and coordinate socially. ...

A new theory proposes that the universe's fundamental forces and particle properties may arise from the geometry of hidden extra dimensions. These dimensions could twist and evolve over time, forming stable structures that generate mass and symmetry ...

Scientists have discovered that key compounds from cannabis--CBD and THC--show surprisingly strong effects against ovarian cancer cells. Used together, they slow cell growth, reduce colony formation, and may even block the cancer's ability to spread. ...

The study reveals how Balanophora plants function despite abandoning photosynthesis and, in some species, sexual reproduction. Their plastid genomes shrank dramatically in a shared ancestor, yet the plastids remain vital. Asexual reproduction appears ...

A series of century-scale droughts may have quietly reshaped one of the world's earliest urban civilizations. New climate reconstructions show that the Indus Valley Civilization endured repeated long dry periods that gradually pushed its people ...

Male bonobos have an impressive ability to detect when females are most fertile, even though the usual visual cues are unreliable. Researchers tracking wild bonobos in the Congo discovered that males skillfully interpret a mix of swelling timing and ...

Scientists have discovered that Madagascar's iconic Pinocchio chameleon is actually a distinct species now named Calumma pinocchio. DNA from both modern samples and centuries-old museum specimens also exposed another hidden species, Calumma ...

A sweeping review of more than 2,500 studies reveals that despite booming public enthusiasm, cannabis has strong scientific support for only a few medical uses, leaving most popular claims--like relief for chronic pain, anxiety, and insomnia--on ...
