Experimental drug reverses severe fatty liver disease by repairing the gut

An experimental drug called DT-109 reversed severe fatty liver disease in animal studies by repairing the gut and preventing harmful toxins from damaging the liver. The discovery could open the door to a new class of treatments for MASH and potentially other diseases tied to gut

Machine learning calibration of biosensors for microcystin toxin monitoring in freshwater

Portable screen-printed carbon electrode (SPCE) biosensors offer a rapid, low-cost way to detect microcystin-lysine-arginine (MC-LR), an extremely potent toxin produced by cyanobacteria during harmful algal blooms in freshwater. Even at low concentrations, MC-LR can damage the li

Shear loading reveals sixfold damage growth around stiff particles in aluminum alloy

The resistance of materials to mechanical loads is a decisive factor in component safety, such as in aircraft. Working as part of an international team, researchers from the Karlsruhe Institute of Technology (KIT) have found a previously unknown damage mechanism in metals: Contam

Evolutionary history shapes plant carbon storage strategies worldwide

Two types of carbohydrates are important to plants—structural carbohydrates (which form cell walls) and nonstructural carbohydrates (NSCs). The latter group represents plants' stored energy reserves, which can be used to survive cold or drought; regrow after damage; recover from
