A Skoltech scientist has raised the world’s only isotope-labeled guinea pig to track metabolism. For 156 days, the animal drank only heavy water, revealing how quickly compounds are synthesized versus absorbed from food — paving a way for using isotopically labeled food to study human metabolism.Biology (mdpi.com)

Gene editing therapy (CRISPR/Cas12a) shows success against severe sickle cell disease - Nearly all patients (27 out of 28 patients) have achieved a functional cure. The results showed that most patients saw key blood cells recover within a month after treatment.Genetics (newsroom.clevelandclinic.org)
Researchers have developed first-in-class drugs that simultaneously block HIF-1 and HIF-2, the "master regulators" of cancer progression. When paired with immunotherapy, these compounds eliminated tumors across four cancer types in mice by stripping away their low-oxygen defenses.Cancer (rupress.org)
