Wireless charging of moving electric vehicles overcomes major hurdle

Stanford scientists have developed a way to wirelessly deliver electricity to moving objects, technology that could one day charge electric vehicles and personal devices like medical implants and cell phones.

If electric cars could recharge while driving down a highway, it would virtually eliminate concerns about their range and lower their cost, perhaps making electricity the standard fuel for vehicles.

10 Ways Earth Once Looked Like An Alien Planet

by Makr Oliver

Before humans, the world was a very different place. Our planet didn’t always look the way it does now. It’s gone through some incredible changes over the past 4.5 billion years—and they’re even wilder than you’ve imagined.

If you could step back in time and stand on the Earth millions of years ago, you wouldn’t just see a few different animals. You’d see an alien planet pulled straight out of a science fiction story.

China | Pollution ‘devastating’ China’s vital ecosystem, research shows

The startling extent to which man-made pollution is devastating China’s vital ecosystem’s ability to offset damaging carbon emissions has been revealed.

A pioneering new international study, led by the University of Exeter, has looked at the true impact air pollutants have in impeding the local vegetation’s ability to absorb and store carbon from the atmosphere.

Rover findings indicate stratified lake on ancient Mars

A long-lasting lake on ancient Mars provided stable environmental conditions that differed significantly from one part of the lake to another, according to a comprehensive look at findings from the first three-and-a-half years of NASA’s Curiosity rover mission. While previous work had revealed the presence of a lake more than three billion years ago in Mars’ Gale Crater, this study defines the lake’s chemical conditions and uses Curiosity’s powerful payload to determine that the lake was stratified. Stratified bodies of water exhibit sharp chemical or physical differences between deep water and shallow water. In Gale’s lake, the shallow water was richer in oxidants than deeper water was.

Mind-controlled device helps stroke patients retrain brains to move paralyzed hands

Stroke patients who learned to use their minds to open and close a device fitted over their paralyzed hands gained some control over their hands, according to a new study from Washington University School of Medicine in St. Louis.

By mentally controlling the device with the help of a brain-computer interface, participants trained the uninjured parts of their brains to take over functions previously performed by injured areas of the brain, the researchers said.
