“Feynman famously said that superposition is the only mystery in quantum mechanics, but more recently entanglement has been widely considered as an additional fundamental feature of quantum physics. Here we show that they are one and the same.” (PhysOrg )

From New Scientist: “David Eagleman of Baylor College of Medicine in Texas has looked at more than 1000 synaesthetes who see colours when viewing some letters and numbers. He found that frequently used letters are most likely to evoke colours, while letters such as Q and X are less likely to do so. However, Eagleman spotted two frequently used letters that bucked this trend: I and O. He also noticed that the numbers 1 and 0 are often not coloured. Eagleman thinks this may be because these characters are made up from natural shapes that we learn to recognise before mastering the alphabet or learning to …”

Destination of ‘recycled’ electronics may surprise you: “While there are no precise figures, activists estimate that 50 to 80 percent of the 300,000 to 400,000 tons of electronics collected for recycling in the U.S. each year ends up overseas. Workers in countries such as China, India and Nigeria then use hammers, gas burners and their bare hands to extract metals, glass and other recyclables, exposing themselves and the environment to a cocktail of toxic chemicals.” (CNN)
