Despite residing in it, it’s hard for us to know exactly how big the Milky Way is. But new research has found that our galaxy is bigger than previously thought. Using a large survey of stars instead of just models (as previous researchers did), astronomers have now determined the disk of our galaxy to be 200,000 light-years across &ac ...read more

Frogs in a rainforest? Sure, rainforests are home to tons of them. Nothing new there — except that researchers just found four, preserved in amber and nearly 100 million years old, that suggest frogs have been hanging out in that environment much longer than previously shown.
Anura, the amphibian order that includes frogs and toads ...read more
We’re around magnets so much, it’s easy to forget they’re kind of magic. Not only do magnets make for fun toys, they can attract or repel objects from a distance through an invisible force, they can create electricity (and vice versa) and they can make cool new tools and materials possible.
A team of mechanical engineers from MIT and the New Jersey Institute of Technology has gone down that last path, publishing in Nature today a new ...read more

Some 3 trillion tons of ice has melted from Antarctica since 1992, and there’s not much time to change course. That’s according to a sweeping group of studies published Wednesday in the journal Nature that looks at the past, present and future of Antarctic ice sheets.
Scientists are calling it the most complete picture ever of ice loss on th ...read more
