Researchers Invent a Camouflage Material That Changes Like a Chameleon

Mother Nature has already mastered the art of camouflage, so it only makes sense that we steal her ideas when it comes to the art of hiding. Researchers at the University of Michigan have developed a remarkable new material "inspired" by chameleons, which can change shape and color under different lighting conditions. » 4/23/14 9:40am Yesterday 9:40am

The Jedi Putter's Constant Feedback Makes You a Master of the Green

Mastering the perfect golf swing is a lot harder than it looks, and putting is even harder than blasting a golf ball down the fairway. So while it will probably never be approved for use in PGA tournaments, the Jedi Putter—designed by students at Rice University—provides real-time feedback helping an amateur golfer… » 4/22/14 11:30am Tuesday 11:30am

A 3D-Printed Ultrasound Cast That Looks Awesome and Heals You Faster

Old-fashioned casts are nasty, a festering stinksleeves that you wear like a medieval torture device for what seems like forever. 3D-printed casts take care of the smell and itch issues, and now Deniz Karasahin has designed the next step: a custom cast with an ultrasound device to speed up bone healing. » 4/18/14 12:40pm 4/18/14 12:40pm

Researchers Develop a Way to X-Ray Rocks To Find Hidden Diamonds

It's no surprise that the diamond industry is willing to spend whatever it takes to make the process of mining precious gems even more profitable. And while it already relies on X-ray technology for spotting diamonds on the surface of mined ore, researchers at the Fraunhofer Institute's Development Center for X-ray… » 4/18/14 10:40am 4/18/14 10:40am

Your Touchscreen Usage Is So Unique It Can Be Used as a Password

It turns out that your seemingly random taps, swipes, and other finger gestures on a touchscreen display might not be so random after all. In fact, the way you interact with a touchscreen is so unique that researchers at Georgia Tech have successfully created software that can lock down your tablet if someone else… » 4/17/14 1:20pm 4/17/14 1:20pm

Tiny Magnetic Robots Might One Day Work On Equally Tiny Assembly Lines

We've successfully engineered giant robot arms for building cars on an assembly line. But smaller mass-produced items—like electronics—still mostly rely on the nimble hands and fingers of a human. Building and controlling robots on a very small scale is still very difficult, but a company called SRI International may… » 4/16/14 4:20pm 4/16/14 4:20pm

British Scientists Say They've Created Artificial Blood for Humans

Somebody ring the bell at the blood factory, because it's almost time to get those assembly lines running. Almost. A team of British scientists say they've created red blood cells suitable for transfusion into humans, a breakthrough that could change the lives of millions—if it works. » 4/14/14 1:20pm 4/14/14 1:20pm

Scientists Manipulate Genes to Make Old Organs Young Again (in Mice)

Researchers at the University of Edinburgh showed this week that they could teach an old mouse's thymus to bounce back to a healthy, youthful state, simply by manipulating a single protein that controls gene expression. It's the first time scientists have been able to regenerate a living organ by gene manipulation, and … » 4/10/14 10:10am 4/10/14 10:10am

Bad News: E-Cigs Alter Cells a Lot Like Tobacco Does

A new cancer study brings more bad news to the e-cigarette industry. Scientists exposed human bronchial cells to e-cig vapor and found that it altered the cells in a way not dissimilar to tobacco. In other words, that delicious, seemingly risk-free nicotine vapor might not be so benign, after all. » 4/09/14 3:20pm 4/09/14 3:20pm

A Powerful Chemistry Tool Inspired by Music Boxes Only Costs $5

Stanford University's Manu Prakash, Ph.D., loves coming up with cheap, rugged scientific equipment, like his 50-cent microscope made of folded cardboard. Now he's followed that up with another ingenious chemistry tool: A $5 device that uses the guts from a music box to control chemical reactions with super precision. » 4/08/14 12:40pm 4/08/14 12:40pm

An RC Plane That Flies on Seawater Fuel

It's been almost a year and a half since we first reported on the U.S. Navy's plans to produce cheap liquid fuel from seawater. And as a proof of concept, the unmodified two-stoke engine in this P-51 Mustang remote control model plane was recently powered using the new liquid fuel instead of traditional gas. » 4/07/14 11:20am 4/07/14 11:20am

Tomorrow's Cancer-Blasting Wonder Drug Could Come From a Tobacco Plant

Australian researchers published findings this week on a newly-discovered plant compound that destroys cancer cells, but leaves healthy cells unharmed. They found it in possibly the last place you'd look for a cancer cure: the family of plants that brings us cancer's number-one culprit, tobacco. » 4/05/14 6:30pm 4/05/14 6:30pm

Researchers Found a New, Easy Way to Turn Graphite Into Diamond

Since graphite—the dark material used in regular old pencils—and diamonds are both made from carbon, it's technically feasible to turn the former into the latter. You just need to apply a little pressure—about 150,000 times what the atmosphere on Earth's surface is like. But researchers at Stanford University claim to… » 4/04/14 9:40am 4/04/14 9:40am

Mosquito Matchmaker: An Inside (Itchy) Look at Force-Mating Mosquitoes

The worst thing about feeding hundreds of mosquitoes on your own blood is not the itching – if you do it enough times, your body gets used to the bites. It's not even the pain, although it is always painful since the mosquitoes will use their snouts to root about your flesh in search of a blood vessel. » 4/02/14 1:00pm 4/02/14 1:00pm

Hypnotic Flapping Wing Turbines Keep Working in the Gentlest Breeze

There have been many proposed alternatives to the spinning propeller blades used on wind turbines installed all over the county, but none as unorthodox as Festo's new DualWingGenerator. Inspired by the company's work on winged flying robots, the design keeps working when winds are as slow as nine miles per hour. » 4/01/14 4:20pm 4/01/14 4:20pm
