Researchers at The University of Texas at Austin have rewritten a small part of Oklahoma's geologic history with global implications for ancient life. Below the surface of the small town of Ames, Oklahoma, a meteor impact site spans miles. The crater is buried by sedimentary strata in the subsurface, but it remains an important marker of Oklahoma's ancient past and present-day economy; the Ames impact structure is a major oil and gas producer.

This new concrete is stronger and pulls CO2 from the air

Researchers have created a concrete mixture that is both stronger and capable of absorbing carbon dioxide. The best formula, combining zeolite with bamboo biochar, boosted compressive strength by 7.48% and tensile strength by 15% compared with conventional concrete. It also captu

Exposed ends and bends attract DNA-cutting enzymes, live imaging reveals

Researchers at the Nano Life Science Institute (WPI-NanoLSI) at Kanazawa University have directly visualized how enzymes find and break DNA molecules in real time. Using high-speed atomic force microscopy, the team followed individual enzymes as they moved along DNA and found tha

Scientists gave worms magnetic bacteria. They lived 43% longer

A magnet-producing bacterium extended the average lifespan of C. elegans worms by more than 43% while helping protect their neurological and intestinal health. Researchers traced much of the effect to suppression of ferroptosis, a damaging form of cell death linked to iron buildu
