OLEDs are thin, organic materials sandwiched between two electrodes, which illuminate when an electrical charge is applied. They’re so thin, that they could be applied to rooms as a type of wall paper to glow at the touch of a finger or when someone enters the room. Like LEDs they produce light very efficiently. But OLEDs also have to potential to be made at a very low cost, because they can be printed “roll-to-roll” like a newspaper. GE recently demonstrated the first OLEDs to be made in this manner — the researchers worked for four years on this project. See more at the GE Blog.

We all know about the egg industry’s appalling record in terms of environmental and animal welfare management. Now, let’s not kid ourselves: overcooking eggs does not address the risk of salmonella infections. Neither does buying “organic” eggs. Salmonella is but the tip of the iceberg. Our responsibility, as consumers, is to pay close attention to the origin of the eggs we buy and to educate ourselves about the producer’s operations. First off, don’t let an organic egg fool you: “organic” refers to the quality of the feed given to the hens but says nothing about their condition of living. Which leads us to the second essential point: a battery-cage egg is not a cage-free egg is not a free-range egg is not a pasture-raised egg. These classifications have real implications for our health and the environment. To find out why, check out Rodale.com editor Leah Zerbe’s cue cards . The great news is that the consumer is not alone anymore when having to choose between eg...
