Astronomers capture first close-up image of star outside Milky Way

Astronomers have captured the first close-up image of a star outside the Milky Way, WOH G64, located in the Large Magellanic Cloud. This red supergiant is nearing the end of its life and may soon go supernova. New research suggests that fat cells have a "memory" that makes it hard to maintain weight loss. Experiments show that epigenetic changes in fat cells persist even after losing weight, potentially explaining the yo-yo effect in dieting. Chemists at University College London have created the world's thinnest spaghetti, measuring just 372 nanometers wide. This strand is 200 times narrower than a human hair and can only be seen with an electron microscope.
