"According to an article on Time.com about the best and worst learning techniques, active learning methods (e.g. writing) are far more useful for long-term retention than passive learning methods (e.g. highlighting or underline words). One of the best ways? Surprisingly enough: flashcards, according to research from the Association of Psychological Science."

"With math equations that analyze brush strokes, new discoveries about the world's greatest art are possible. It took X-ray fluorescence spectroscopy and a painting algorithm to reveal the hidden portrait of a peasant underneath the painting of Vincent Van Gogh's "Patch of Grass."

"As with many schools in the United States, the shop program at Analy High School in Sebastopol, California, had become largely irrelevant. The main shop room had become little more than a glorified storage room. The school's priorities were firmly focused on college readiness and success at standardized tests, and vocational programs had taken a backseat. Sebastopol is also the home of Make magazine, one of the leading voices of the maker movement, a community of inventors and do-it-yourselfers that has blossomed on YouTube and shows up in the tens and sometimes hundreds of thousands at Maker Faires all over the world. Make proposed that a group of students from Analy come to their offices to explore the possibilities involved in creating things with 3-D printers, computer-aided design, and more. The program was so popular that soon Make could no longer accommodate it in their offices, so they agreed to donate equipment to Analy if the school would ramp up their vocational program."

"So far I've done interviews with 22 experts on various fields from happiness, to expertise, to influence and irrationality. I've asked most of them which books they highly recommend."

"Students perform better if they share an iPad with another student as opposed to having one all to themselves, according to a new study. Though schools nationwide have ramped up their efforts to introduce technology in the classroom, there's just a small body of evidence on the benefits for students. Now a new study suggests that iPads do have a role in academic performance, but the effect may be greater when students collaborate."

"Pity the summertime. All year, we long for better weather, using this season as a repository for our plans. I'll paint the house in the summer. I'll plant a garden in the summer. I'll reorganize the garage in - you guessed it - the summer. But all those plans jamming up our calendar doesn't leave much time for anything fun. These seven apps can help you keep track of your various household chores and projects, so you can spend more time getting things done and less time keeping track of them."

Phones and computers contain dangerous metals like lead, cadmium and mercury, which can contaminate the air and water when those products are dumped. It's called electronic waste, or e-waste, and the world produces a lot of it: 20 to 50 million tons a year, according to the UN - enough to load a train that would stretch around the world. The U.S. is by far the world's top producer of e-waste, but much of it ends up elsewhere - specifically, in developing nations like China, India and Nigeria, to which rich countries have been shipping garbage for years.
