Through twists of light

Two centuries ago a French engineer noticed something special about light from the sun and discovered the phenomenon of polarisation of light. Now using that property of light scientists have developed a  technique to spot the presence of water and other biological molecules on the many Earth-like planets. With more powerful telescopes being built, they might just be able to search for life through the twists of light.

Done by temptation

The Drosophila melanogaster species of fruit fly has marked similarity to humans in its choice of sweeteners, a fact exploited by a team led by Anne Rae at the Commonwealth Scientific and Industrial Research Organisation in Queensland to aid the search for new sweeteners as demand for healthier sugar alternatives grows.
