It's like something out of a science fiction novel or a Harry Potter book. Engineers from Duke University have constructed a device that can "cloak" items placed on a mirror surface.
First designed in 2006, the new version of the device is a more sophisticated and complicated design that can cloak a wider variety of waves.
Don’t have the time or money to fly to Spain to visit the famous Prado Museum in Madrid? No problem. Today, Google launches the Prado layer on Google Earth. Now you can view masterpieces like Velazquez’s The Maids of Honor or Rembrandt’s Artemis in high resolution.
A team of coal miners is working hundreds of feet underground when an explosion rocks the tunnel. They scramble for an exit, but those are all blocked. The air fills with dust and gas. There's no escape ... so the survivors inflate a portable panic room, complete with an oxygen supply and air filters, and wait for help. At least that's how Jim Reuther, a senior research scientist at the R&D giant Battelle, hopes the situation pans out.
The "Ruben's Tube" demonstration shown in the video gives a dramatic and visual representation of sound waves creating standing waves in a pipe. Whether or not you light the gas, once the speaker is on, there are sound waves traveling back and forth along the tube. Sound waves consist of alternating regions of high and low pressure. But by igniting the gas in the tube and allowing it to escape out of the holes cut into the top, we can see where the pressure is high and where it is low.
The oldest known human brain from the Old World—comprised of Europe, Asia, Africa and contiguous islands—has been discovered in Armenia, announced UCLA researcher Gregory Areshian at an annual archeological conference Sunday.
The brain dates back to the Copper age, which ran approximately 5,500 to 6,500 years ago in Eastern Europe and the Near East. Archeologists discovered the brain, believed to be that of a young girl, while excavating for relics in the past two years inside and outside of Armenia's 600-square-meter Areni-1 cave across the border from Iran.
Silicon wafers, the backbone of the electronics industry, are brittle and fragile. So researchers have sought to create a more supple polymer surface that can be stretched, twisted, and bent in any direction and to populate it with newly engineered circuits. The solution: "pop-up" wire connections between the circuit components, along with flexible S-curves in the wires that can unwind and slip back into shape.
“Stress relievers” that typically come to mind in reference to college life include partying hard, engaging in fraternity shenanigans, and ordering pizza. Add pet ownership to that list. A new study out of Ohio State University found that pets-- not beer-- are help college students to get through difficult times.
