Scientific American: 50 Innovations

Continuing the "best of" theme: Scientific American rounds up the top 50 innovations in the last year in categories such as "policy," "fueling alternatives," "advances in ultrameasurement," "neurological insights," "light manipulation" and "squirt and spin." 

According to SciAm, "this year’s SciAm 50 awards are replete with instances of new machines or chemicals that come close to the true meaning of innovation as something entirely new."
