Zhang asked all of the normal childhood questions - such as, “Why is the sky blue?” - but with two chemists for parents, his answers always came in the most literal, scientific form.

Cambridge, Massachusetts - Today’s computer chips pack billions of tiny transistors onto a plate of silicon within the width of a fingernail. Each transistor, just tens of nanometers wide, acts as a switch that, in concert with others, carries out a computer’s computations. As dense forests of transistors signal back and forth, they give off heat - which can fry the electronics, if a chip gets too hot.

Boulder, Colorado - A tougher federal standard for ozone pollution, under consideration to improve public health, would ramp up the importance of scientific measurements and models, according to a new commentary published in the June 5 edition of Science by researchers at NOAA and its cooperative institute at the University of Colorado Boulder.
