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.

Using modern research tools on a 155-million-year-old reptile fossil, scientists at Johns Hopkins and the American Museum of Natural History report they have filled in some important clues to the evolution of animals that once roamed land and transitioned to life in the water.

In First, 3-D Printed Objects Connect to WiFi Without Electronics

University of Washington engineers have developed the first 3-D printed plastic objects that can connect to other devices via WiFi without using any electronics, including a laundry bottle that can detect when soap is running low and automatically order more.

Wearable Computing Ring Allows Users to Write Words and Numbers with Thumb

With the whirl of a thumb, Georgia Tech researchers have created technology that allows people to trace letters and numbers on their fingers and see the figures appear on a nearby computer screen. The system is triggered by a thumb ring outfitted with a gyroscope and tiny microphone. As wearers strum their thumb across the fingers, the hardware detects the movement.

Decline in Atmospheric Carbon Dioxide Key to Ancient Climate Transition

A decline in atmospheric carbon dioxide (CO2) levels led to a fundamental shift in the behaviour of the Earth’s climate system around one million years ago, according to new research led by the University of Southampton.

How the Earth Stops High-Energy Neutrinos in Their Tracks

A research collaboration including scientists from Berkeley Lab has demonstrated that the Earth stops high-energy neutrinos – particles that only very rarely interact with matter.

Biomechanical Model Could Reduce Wobbling Of Pedestrian Bridges, Study Finds

The dangerous wobbling of pedestrian bridges could be reduced by using biomechanically inspired models of pedestrian response to bridge motion and a mathematical formula to estimate the critical crowd size at which bridge wobbling begins, according to a study led by Georgia State University.
