Scientists at UC San Diego have identified a new drug, ION224, that could transform the treatment of MASH, a dangerous form of fatty liver disease tied to obesity and diabetes. By blocking a key liver enzyme, the drug reduces fat and inflammation, halting the root causes of liver damage. In a year-long clinical trial, patients …

Scientists in Canada have uncovered a surprising culprit behind high blood sugar and liver problems: a hidden fuel made by gut bacteria. This little-known molecule, called D-lactate, slips into the bloodstream and pushes the liver to make too much sugar and fat. By creating a simple “trap” that blocks the molecule in the gut, researchers …

Scientists at Stellenbosch University have uncovered a rare class of plant compounds, flavoalkaloids, in Cannabis leaves for the first time. Using advanced two-dimensional chromatography and mass spectrometry, they identified 79 phenolic compounds across three strains, 25 of which had never before been reported in Cannabis. The surprising discovery highlights the complexity of the plant and …
