How Free Is Your Will?
From Scientific American:
Think about the last time you got bored with the TV channel you were watching and decided to change it with the remote control. Or a time you grabbed a magazine off a newsstand, or raised a hand to hail a taxi. As we go about our daily lives, we constantly make choices to act in certain ways. We all believe we exercise free will in such actions – we decide what to do and when to do it. Free will, however, becomes more complicated when you try to think how it can arise from brain activity.
Do we control our neurons or do they control us? If everything we do starts in the brain, what kind of neural activity would reflect free choice? And how would you feel about your free will if we were to tell you that neuroscientists can look at your brain activity, and tell that you are about to make a decision to move – and that they could do this a whole second and a half before you yourself became aware of your own choice?

A New Tool for Creative Thinking: Mind-Body Dissonance
From Scientific American:
A New Tool for Creative Thinking: Mind-Body Dissonance
Did you ever get the giggles during a religious service or some other serious occasion? Did you ever have to smile politely when you felt like screaming? In these situations, the emotions that we are required to express differ from the ones we are feeling inside. That can be stressful, unpleasant, and exhausting. Normally our minds and our bodies are in harmony. When facial expressions or posture depart from how we feel, we experience what two psychologists at Northwestern University, Li Huang and Adam Galinsky, call mind–body dissonance. And in a fascinating new paper, they show that such awkward clashes between mind and body can actually be useful: they help us think more expansively.

Jevons Paradox: Energy Efficiency Increases Consumption?
Energy efficiency sounds simple, but it’s rather difficult to measure. Sure when you purchase a shiny, new more energy efficient washing machine compared with your previous model you’re making a personal dent in energy consumption. But, what if in aggregate overall consumption increases because more people want that energy efficient model? In a nutshell, that’s Jevons Paradox, named after a 19th-century British economist, William Jevons. He observed that while the steam engine consumed energy more efficiently from coal, it also stimulated so much economic growth that coal consumption actually increased. Thus, Jevons argued that improvements in fuel efficiency tend to increase, rather than decrease, fuel use.
John Tierney over at the New York Times brings Jevons into the 21st century and discovers that the issues remain the same.
From the New York Times:
For the sake of a cleaner planet, should Americans wear dirtier clothes?
