Researchers at the University of California-Berkeley have designed a new membrane that wraps around a building instead of walls, filled with micro-scale valves and lenses that open and close as they sense light, heat, and humidity. The facade works with no power at all—not even solar panels—and keeps the temperature comfortable and light bright inside.
Princeton University researchers have developed a new method to increase the brightness, efficiency and clarity of LEDs, which are widely used on smartphones and portable electronics as well as becoming increasingly common in lighting.
The solution presented by Chou’s team is the invention of a nanotechnology structure called PlaCSH (plasmonic cavity with subwavelength hole-array). The researchers reported that PlaCSH increased the efficiency of light extraction to 60 percent, which is 57 percent higher than conventional high-end organic LEDs. At the same time, the researchers reported that PlaCSH increased the contrast (clarity in ambient light) by 400 percent. The higher brightness also relieves the heating problem caused by the light trapped in standard LEDs.
In the U.S., consumers account for the biggest share of waste in the food chain. Demand for stocked shelves and unblemished produce, and confusion over date labels lead to mountains of tossed meals.
…A full 10 percent of the available food supply in the U.S. is wasted every year at the retail level, according to the U.S. Department of Agriculture, and about 20 percent is wasted at home. That’s food worth more than $160 billion. And it’s food that could go toward feeding the estimated 1 in 7 American households that can’t find enough to eat.
…To reduce the food waste that gets trucked to a landfill, many supermarkets are turning to compost. Compost companies can take organic waste and turn it into a valuable soil amendment… Around the country, supermarkets are also using software that projects how much food to order from the warehouse, so they’re not stuck with massive amounts of extra.
John Oliver astutely outlines the looming threat of losing Net Neutrality and letting major cable companies, who have spent tens of millions of dollars in lobbying alone, gain control over the very law that is supposed to regulate them and mutilating legislation to boost their own profits while hurting customers.
This is real - it’s happening right now. The corruption is so large and runs so deep that it is glaringly obvious even at the surface.
