Picking the best toothpaste can be a challenge, especially with newer ingredients being added to the market. Nano-hydroxyapatite is a timely example and the star ingredient for popular brands like Boka and Davids. Amidst health concerns around fluoride and Robert F. Kennedy Jr., US Secretary of Health and Human Services, proposing to remove it from public water, nano-hydroxyapatite has been promoted as an effective alternative to fluoride in toothpaste.

The words "satellite phone" probably conjure up an image of a clunky mobile monstrosity straight out of a spy thriller. These bulky and utilitarian traditional satellite phones are typically required in remote locations where cellular networks are unavailable. Nowadays, however, satellite connectivity can be found in regular smartphones too, thanks to new hardware innovations and unique partnerships with satellite network providers.

arstechnica.com Unknown 2026-02-13 18:15:02

NASA's New Horizons spacecraft got a fleeting glimpse of Pluto 10 years ago, revealing a distant world with a picturesque landscape that, paradoxically, appears to be refreshing itself in the cold depths of our Solar System. The mission answered numerous questions about Pluto that have lingered since its discovery by astronomer Clyde Tombaugh in 1930. As is often the case with planetary exploration, the results from New Horizons' flyby of Pluto on July 14, 2015, posed countless more questions.
