Scientists have sequenced the complete genome of an ancient strain of Hepatitis B, shedding new light on a pathogen that today kills nearly one million people every year. The findings, based on data extracted from the mummified remains of a small child buried in Naples, Italy, confirm the idea that HBV has existed in humans for centuries.

Star Mergers: A New Test of Gravity, Dark Energy Theories

Observations and measurements of a neutron star merger have largely ruled out some theories relating to gravity and dark energy, and challenged a large class of cosmological theories.

The Force Is Strong: Amputee Controls Individual Prosthetic Fingers

Luke Skywalker’s bionic hand is a step closer to reality for amputees in this galaxy. Researchers at the Georgia Institute of Technology have created an ultrasonic sensor that allows amputees to control each of their prosthetic fingers individually. It provides fine motor hand gestures that aren’t possible with current commercially available devices.

Decades-Past Logging Still Threatens Spotted Owls in National Forests

Logging of the largest trees in the Sierra Nevada’s national forests ended in the early 1990s after agreements were struck to protect species’ habitat. But new research reported Dec. 6 in the journal Diversity and Distributions by University of Wisconsin–Madison ecologists shows that spotted owls, one of the iconic species logging restrictions were meant to protect, have continued to experience population declines in the forests.
