Gallium nitride transistors promise brighter future for LEDs

Gallium nitride transistors promise brighter future for LEDs: "New advances in transistor technology could make the light-emitting diode (LED) the commercial light source of the future.

Although known for long life and low energy consumption, the LED uses a DC power supply, or driver, to overcome its sensitivity to current fluctuations, and it’s the high-frequency, high-speed switching transistors in this driver that’s made the LED so costly for use in large-scale commercial applications dominated by fluorescent and incandescent lighting."

Flashback Friday: Farts: an underappreciated threat to astronauts. - Seriously, Science? | DiscoverMagazine.com

Flashback Friday: Farts: an underappreciated threat to astronauts. - Seriously, Science? | DiscoverMagazine.com: "On Earth, farts are typically no big deal — smelly, harmless, and they quickly dissipate. But if you’re an astronaut, every fart is a ticking time bomb. The gases in farts are flammable, which can quickly become a problem in a tiny pressurized capsule in the middle of space where your fart gases have no where to go"

World's first 3D acoustic cloaking device created

World's first 3D acoustic cloaking device created: "Metamaterials are already being used to create invisibility cloaks and "temporal cloaks," but now engineers from Duke University have turned metamaterials to the task of creating a 3D acoustic cloak. In the same way that invisibility cloaks use metamaterials to reroute light around an object, the acoustic cloaking device interacts with sound waves to make it appear as if the device and anything hidden beneath it isn't there."
