Astronomers may have discovered one of the clearest examples yet of a rare "pair-instability" supernova. It is a catastrophic explosion thought to completely destroy some of the most massive stars in the universe, leaving ...

China's Tianwen-2 sample-return mission is well on its way to its target, an asteroid called Kamo'oalewa. The spacecraft left Earth in May 2025 and should return in late 2027 with samples of a space rock that scientists had ...

Researchers from the National University of Singapore (NUS) have developed a computation-guided strategy to produce urea more efficiently from carbon dioxide and nitrate. By combining large language models, density functional ...

The first day of kindergarten is a momentous occasion for children and families. It's an exciting milestone that comes with new friends, teachers, and learning opportunities. It can also bring parental anxiety about whether ...

In the canals, wetlands and marshes of the Florida Everglades, the spectacled caiman has quietly expanded its foothold, threatening an already-vulnerable ecosystem. A new University of Florida study published in Frontiers ...
