Cheap and cheerful: scientists find colour that never fades

Source : Agencies | 11 Sep 2012

Scientists have found nature's way of creating colour that never fades, a technique they say could replace pigments used in industry with natural plant extracts in products from food colouring to security features in banknotes.

Layers of cellulose that reflect specific wavelengths of light - 'structural colour' found in peacock feathers, scarab beetles and butterflies - make a particularly intense blue in the Pollia condensata plant, scientists say.

The world is depleting underground water reserves faster than they can be replenished due to over-exploitation, according to scientists in Canada and the Netherlands.

The fireball was spotted in the sky six months ago, but the rocks were not discovered on the ground in North Africa until the end of December.
