Growing up Neanderthal: Lead Exposure, Extremely Cold Conditions

Posted on Categories Discover Magazine

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

(Credit: École polytechnique fédérale de Lausanne) A spinal cord injury used to mean life bound to a wheelchair. Now, three spinal cord injury patients are able to walk and even ride a modified bicycle, new research shows. The trio got on their feet again thanks to well-timed and precise electrical stimulation in the spinal cord combined with rehabilitation. The results are just ...read more

How A Catastrophic Cosmic Collision Changed the Milky Way Forever

Posted on Categories Discover Magazine

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
