Hidden erosion: Study reveals soft mountain rock erodes three times faster than hard rock—with climate implications

A University of Massachusetts Amherst-led research team has discovered that weaker rock in mountain landscapes erodes three times faster than harder rock—even on gentler slopes—and is one of the main attributes governing mountain erosion. The finding also challenges our current understanding of the relationship between erosion and the release of carbon dioxide, and suggests that geologists and atmospheric scientists may be underestimating the CO₂ contributions coming from the Earth's rocky places.

Why it could be a bad idea to get AI to flirt for you

You finally started an online conversation with a stranger you find attractive, yet you don't really know what to say. They seem happy to talk, but you struggle to find the correct responses. You worry that their patience is growing thin. You pray for some guidance. Luckily, the solution could be just a few clicks away.

Four new frog species reveal more of Peru's biodiversity

Science can't study a species—or unlock its potential to change the world—until people actually know it exists. Four new species of frogs have now been given names, thanks to the efforts of FIU biologist Alessandro Catenazzi.

Novel chemical reaction expands options for building DNA-encoded libraries

Finding new drugs requires screening vast numbers of compounds to identify those that interact with a biological target. DNA-encoded libraries (DELs) help researchers explore these large collections by attaching a short DNA sequence to each molecule, acting as a molecular barcode that allows compounds with promising properties to be identified.

Survey reveals what students think about AI

College students say they use AI mostly for learning and don't use it to cut corners but think that their peers do, according to the inaugural Dartmouth AI Survey, a new multiyear survey on how AI is shaping students' learning and career readiness.

Crop diversification protects fields from extreme weather and boosts productivity

Varying crop rotations and keeping the soil constantly covered with vegetation help protect crops against droughts and floods, in addition to increasing productivity. This technique was tested in Rio Grande do Sul state, Brazil, by researchers from the Center for Carbon Research in Tropical Agriculture (CCARBON) at the University of São Paulo (USP).
