The two missions, with launch windows that opened January 21, 2025, are aiming for the Alaskan night sky, where auroras shine regularly during the winter.

For adults of a certain age, dental implant advertisements appear ubiquitous. But the price — at potentially thousands of dollars per tooth — might, for many people be a case of financially biting off more than they can chew.What if, instead, they could regrow their pearly whites, perhaps at a fraction of the cost?Approaches that replace — rather than patch up — teeth with crowns or fillings may be closer than you think.
