NASA recently announced the instruments that will be aboard the rover for its next mission to Mars in 2020. Pictured above is an artist's rendition of the robot as it operates the SuperCam, a device that will fire a high-powered laser at rock targets up to 20 feet away.
If you take a stroll down the "pink" aisle at the toy store, you'll come across princesses, dress-up kits and dolls. With an abundance of these popular items, it's no wonder research shows that girls lose interest in science, technology, engineering and mathematics (STEM) fields as early as age 8. While all of these items are a great way for girls to interact and imagine, it's time for us to alter the way we think about toys for girls.
There is no cure for Alzheimer's disease, no definitive test and no way to prevent it. Yet when asked, an overwhelming number of people around the world say they want to know whether they are at risk. "I was surprised by the consistency and strength of that need," says Ben Newton, who leads the neurology unit at GE Healthcare Life Sciences. "This strength of feeling is rare for a disease that we cannot treat."
Scientists are learning to diagnose and even predict the onset of incurable neurological diseases like Alzheimer's and Parkinson's earlier and earlier. As doctors get closer to predicting whether you will develop an incurable disease at some point in your life, an important question pops up: would you want to know, even if there was no cure?
Octopus-Inspired Camo Changes Color In Light
Researchers have taken a tip from the ocean's masters of disguise to develop a new active camouflage system.
Lincoln shows there is no electric field drop in a conductor by placing one area of a fluorescent bulb inside the field. This forms a glowing conductive plasma that grows as the bulb is pulled across.
The electric field that extends beyond the plasma globe's glass becomes visible when fluorescent gas in a bulb is brought inside the region.
3-D printing seems to have made everyone's shortlist of "disruptive technologies," but the real disruption yet to materialize is at the consumer level. The desktop production facility has enjoyed a high profile for its potential to change the face of manufacturing and retailing. Like the early iteration of a miracle technology that might be seen on Star Trek, the computer-controlled devices can build real three-dimensional things right before your eyes --- no assembly plant required.
