Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular processes can create voltage spikes similar to those used by neurons. These signals could help drive ion transport and ...

Scientists have digitally reconstructed the face of a 1.5-million-year-old Homo erectus fossil from Ethiopia, uncovering an unexpectedly primitive appearance. While its braincase fits with classic Homo erectus, the face and teeth resemble much older ...

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 ...

A rare, ultra-long earthquake in Myanmar revealed that mature faults can deliver their full force directly to the surface. The discovery could mean stronger shaking near faults like California's San Andreas than current models predict.

Around 1,000 years ago, a major climate shift reshaped rainfall across the South Pacific, making western islands like Samoa and Tonga drier while eastern islands such as Tahiti became increasingly wet. New evidence from plant waxes preserved in ...

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. ...

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 ...
