For the first time, astronomers have measured the mass of a star by observing the way its mass deforms light passing by it.
It’s an observation that Einstein predicted but thought could never actually happen, due to the incredibly precise alignment between distant astronomical objects it entails. But using modern observing tools, re ...read more
One of the earliest known members of Homo sapiens was this guy. The composite image, based on micro-CT scans of fossils from a site in Morocco, shows that the modern human face had already evolved by 300,000 years ago, smashing conventional thinking about our evolutionary timeframe.

For decades, based on both the fossil record and, more recently, paleogenomic modeling, researchers have generally put the start date for Homo sapiens around 200,000 years ...read more

For many, science is nothing more than that class you were required to take in school. However, whether you realize it or not, science is all around us, and it impacts every aspect of our lives. And, the stories behind key scientific discoveries, though not commonly known, are truly inspiring.
So, if you want a quick refresher on how the universe works, focus on these four f ...read more
Feathered tyrannosaurs? No, thank you. These dinosaurs didn’t need no stinkin’ feathers, and a new study backs me up on that. (Credit David Monniaux/Wikimedia Commons)
It’s a good day here at Dead Things: A new study provides a nice big nail in the coffin of the notion that T. rex and its kin ran around all kitted out in feathers. Lovers of old-school, scaly dinosaur renderings, rejoice!
Maybe I’m showing my age, but when I was learning about dinosaurs they were ta ...read more
