New evidence points to two feeding black holes just 175 parsecs apart lurking in the early universe
Astronomers have found two actively feeding supermassive black holes separated by just 175 parsecs (570 light-years) in a galaxy seen when the universe was only about 2 billion years old. The system, MG B2016+112, lies at ...
Common deworming drug helps restore lung cancer's sensitivity to targeted therapy in mice
A form of lung cancer, which is found in about 10%–15% of Western patients and 40%–50% of Asian patients, is driven by a mutation in the epidermal growth factor receptor (EGFR) gene. Gefitinib is a go-to drug that shuts down ...
A gut microbe makes a fatty acid that cuts artery plaque in half in mice
A common gut bacterium produces a molecule that slows cholesterol production in the liver. When researchers gave the molecule to mice prone to artery disease, the animals developed roughly half as much fatty plaque as untreated ...
