Teeth can tell researchers a lot about the past. (Credit: sruilk/shutterstock) Childhood wasn’t easy for Neanderthals.  A new study of Neanderthal teeth published in Science Advances this week tells us new details about what life might have been like for early hominin children in a rapidly changing environment. It’s an unprecedented look into how our ancient cousins coped with harsh climate conditions and seasonal changes in resource availability. Also among the findings ...read more

An illustration of NASA’s Lucy spacecraft. (Credit: SwRI) From Ryugu to Bennu, asteroid exploration has been all the rage among astronomers lately. And now, we’re one step closer to exploring some of the most mysterious asteroids in the solar system. On October 30, NASA announced that they’ve been given the green light to start building Lucy, a spacecraft that will probe Jupiter’s trojan asteroids and is set to launch in October of 2021. On top of giving the g ...read more

The Andromeda galaxy, which researchers think will collide with the Milky Way in billions of years. One new study shows how our galaxy was shaped by a merger with a dwarf galaxy 10 billion years ago. (Credit: NASA JPL) Our galaxy, perhaps like many in the universe, is a bit of a Frankenstein’s monster. A new study makes a compelling case that a central structure in the Milky Way is actually composed mostly of stars born in another galaxy, brought to us by a long-ago galactic smash-u ...read more

A plate from Morton’s 1939 Crania Americana. (Credit: archive.org) Samuel Morton collected and studied hundreds of human skulls in the early 19th century. By objectively measuring differences in brain size between people from various societies, Morton believed he had used science to prove that white people were intellectually superior to other races. Modern science has long since shown that brain size isn’t necessarily related to intelligence. Many researchers suspect brain size is ...read more

(Credit: Saroj Khuendee/Shutterstock) (Inside Science) — Soil bacteria respond dramatically to changes in climate, but the full impacts aren’t felt for at least half a century, according to new research. The findings suggest that today’s climate conditions will continue to cause upheaval in the soil for decades. A team of Chinese and American researchers analyzed data from soil samples collected in recent years from 144 sites in Tibet, the U.S. and Canada. Next, they use ...read more
