Nearly 30 human footprints from at least three different individuals, found at a remote island off Canada’s Pacific Coast, could be the latest evidence that people arrived in North America by sea. At about 13,000 years old, the tracks pre-date the end of the last ice age.

Welcome to Triassic Park! Researchers spent a decade working at remote African sites to fill in serious gaps in our understanding of life at the Dawn of the Dinosaur Age. The scene, including dino-relative Teleocrater in foreground, illustrates what mid-Triassic Tanzania might have looked like 240 million years ago. (Credit Mark Witton/Natural History Museum, London)

How well do we know ourselves? The fossil record of hominins, our ancestors and closest kin, is limited, and the exploration of our collective deep history through genetic analysis is still a relatively new field. Neither excavations nor lab work has been able to reconstruct, definitively, the earliest chapter of the Homo sapiens story.
For decades, two competing models of human evolution have dominated the field. One claims that H. sapiens evolved in a single place, Africa, and left that conti ...read more
Six thousand, five hundred and twenty-one days: That’s how long I’d been living with my son when he left home for college. I’d spooned applesauce into his gummy mouth when he was a baby. I’d watched him wobble down the street on training wheels when he was a preschooler. I’d learned to rise on tiptoes to kiss his stubbled cheek when he was a teenager.
For nearly 18 years, I’d been there for the big moments and the daily nothings. I’d fretted about him an ...read more

NASA will be making history again, soon.
Sometime this spring, if all goes as planned, a SpaceX Falcon 9 rocket will carry the Transiting Exoplanet Survey Satellite (TESS) into space. Once in “high-Earth” orbit, the satellite’s instruments will scan the entire sky, hoping to find small planets outside our solar system. The main targets are potentially habitable worlds that are relatively nearby, within a few hundred light-years.But the mission’s scientific objectives aren ...read more
