Giant snails and tiny insects threaten the South's rice and crawfish farms‎

Josh Courville has harvested crawfish his whole life, but these days, he's finding a less welcome catch in some of the fields he manages in southern Louisiana.

The internet names a new deep-sea species of chiton‎

The Senckenberg Ocean Species Alliance (SOSA), in partnership with the scientific publisher Pensoft Publishers and science YouTuber Ze Frank, have let the internet name a newly discovered deep‑sea chiton (a type of marine mollusk). The formal description of the species is published in the Biodiversity Data Journal.

Raising human capital in BRICS is linked to lower emissions, study suggests‎

Climate change and worsening environmental conditions have brought into sharp relief how we must reconcile development with sustainability. This issue is nowhere more starkly relevant than among the fastest-growing economies. Research published in the International Journal of the Energy-Growth Nexus that examined the BRICS countries, Brazil, Russia, India, China and South Africa, suggests that investment in education and training might play a significant role in reducing environmental harm, a role that has often been overlooked.

Light-driven probe enables sensitive detection of epigenetic intermediates‎

Epigenetic modifications such as DNA methylation play a key role in regulating gene expression. Emerging evidence suggests that intermediates generated during DNA demethylation may have distinct biological roles. However, their detection remains challenging due to their low abundance. Now, researchers from Japan have developed a novel light-sensitive oligonucleotide probe that selectively crosslinks with 5-formylcytosine, an epigenetically important intermediate, enabling its detection in target DNA and complex biological samples.

Governments urged to fix faulty radar in economic models disregarding climate risk‎

Economic models used by governments, central banks and investors are increasingly understating physical climate risk because they rely on assumptions that break down as the world moves toward higher levels of warming, according to a new report from University of Exeter and Carbon Tracker. The report Recalibrating Climate Risk—drawing on expert judgment from more than 60 climate scientists—finds that many economic models are failing to capture the extreme events, compounding shocks and rising uncertainty likely to dominate impacts in a hotter world.

Study: Why Nobel Prize-level materials have yet to reach industry‎

Excess carbon dioxide in the atmosphere, polluted water, and increasingly strict environmental regulations are driving the search for materials that can efficiently trap pollutants at the molecular level. For more than two decades, this challenge has drawn scientific attention to metal–organic frameworks (MOFs)—highly advanced porous materials widely regarded as one of the most promising tools for tackling climate change and environmental pollution.

Into the neutrino fog: The ghosts haunting our search for dark matter‎

Ciaran O'Hare scribbles symbols using colored markers across his whiteboard like he's trying to solve a crime—or perhaps planning one. He bounces around the edges of the board, slowly filling it with sharp angles and curling letters. I watch on, and when he senses I'm losing track, he pauses intermittently, allowing my brain to catch up. Ciaran speaks with an easy to understand British inflection, but the language on the whiteboard might as well be hieroglyphics.
