Achievement unlocked: Rewritable paper.
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.
New research from the University of Geneva is helping us understand how plants protect themselves from the sun.

The risks of UV radiation exposure are well-known, but some scientists are exploring lesser-known benefits of UV light.
The UV Index was created last century largely for North American and European conditions, which rarely reach the ‘extreme’ range.
Alongside the day's high and low, weather reports generally contain a UV alert for a particular time. But what does it actually mean – and what should you do about it?
