The blue shark (Prionace glauca) might be more than its name. Scientists investigating the sleek ocean predator’s skin discovered nanostructures that not only produce its signature hue, but also potentially let it change color like a chameleon. Animals produce their colors in various ways. Some rely on pigmented cells that reflect a color by selectively removing wavelengths from ambient light, …

When astronomers measure the expansion of space in the nearby universe, they find a noticeably faster rate than calculations based on the early cosmos predict. A new analysis presented this week at the Royal Astronomical Society’s National Astronomy Meeting (NAM 2025) proposes an eye-catching fix. …
