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, …

Scientists have warned that this summer could include some of the shortest days of your entire life. On July 22 and August 5, experts predict the day will be 1.38 and 1.51 milliseconds shorter than average, respectively.  This is because the planet’s rotation has entered an unexpected period of acceleration, shaving a millisecond or so off the length of a …

Paleontologists in China have discovered the skeletal remains of a remarkable new genus and species of huge-sized mamenchisaurid dinosaur from the Late Jurassic epoch. Fossil remains of Tongnanlong zhimingi. Image credit: Wei et al., doi: 10.1038/s41598-025-09796-0. The newly-described species lived in what is now southwestern China some 147 million years ago (Late Jurassic epoch). Scientifically named Tongnanlong zhimingi, this sauropod …

A significant discovery in southern Uruguay has raised questions about the timeline of human interaction with megafauna in the Americas. The 33,000-year-old bone of a giant ground sloth, found in Arroyo del Vizcaíno, exhibits distinct markings that may have been caused by human activity. This find suggests that humans could have been hunting these massive creatures much earlier than previously …

For nearly a decade, cosmologists have wrestled with a nagging mismatch called the Hubble tension. 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. …

Protoplanetary disks made of gas and dust form around young stars, and this is where planets from. These disks don’t last forever. Eventually, the star’s energetic output dissipates the disk through photoevaporation, the material gets taken up in planets, and the planet-forming process ceases. All young stars are expected to have protoplanetary disks, and these dusty environments make it difficult …
