NanoLeaf Bulbs Provide Unusually Bright, Energy-Efficient LED Lighting

From lifehacker.com:

We’re all for energy-efficiency, and NanoLeaf managed to pack quite a bit of it into one of the weirdest looking lightbulbs we’ve ever seen. With their LED bulb you get 30,000 hours of brightness equivalent to a standard 100W unit.

NanoLeaf’s bulbs operate at a lower temperature thanks to using LEDs, but they also have “over-temperature protection” to avoid overheating under any circumstances. In addition to cool operation and great efficiency, they’re also constructed without mercury or lead. If you’re looking for a long-lasting lightbulb with great construction, bright light, and a frame that makes for a good conversation piece, you should check these out.

Tiny Injectable LEDs Manipulate the Brain With Light

Tiny, glowing probes packed with LEDs and sensors are scientists’ newest tool for measuring and manipulating the brain and other living tissues. They’re flexible, they can operate wirelessly, and yes, they’re small enough to fit through the eye of a needle.

This kind of device could potentially improve researchers’ ability to influence neural activity in live animals and measure a variety of physiological and biochemical processes, says applied physicist and neuroscientist Mark Schnitzer of Stanford University, who was not involved in the work. Such bio-compatible electronics also offer new possibilities for manipulating living tissue based on rapid feedback from sensors embedded in the tissue.

One obvious application in brain research is for optogenetics experiments, which involve genetically modifying neurons to make them fire in response to light. In recent years neuroscientists have used these methods to examine the neural circuits involved in everything from drug addiction, to depression, to Parkinson’s disease. But getting light to areas deep inside the brain is tricky.
