World hunger has risen for three straight years, and climate change is a cause

After declining for nearly a decade, the number of hungry people in the world is growing again. Climate change, which is disrupting weather patterns that farmers rely on, is a major cause.

The BS and the science of nanotechnology

Last week, Elon Musk 'called BS' on nanotechnology. And it threw up an important question: just what is nanotech, and is it more hype than science?

Reprintable paper becomes a reality

Coating paper with an inexpensive thin film can allow users to print and erase a physical page as many as 80 times. That reduces both the cost and the environmental effects of paper use.
