Levitating flies
UK scientists have used a strong magnetic field to levitate flies in order to simulate the effects of weightlessness in space. The flies in the study walked more quickly and more often in ‘zero gravity’ compared with flies on Earth, confirming results from previous space missions. Understanding how gravity affects biological organisms is vital to the success of future space missions.

Smelly birds
For the first time researchers have shown that birds can use smell to recognise their relatives and avoid inbreeding with them. The study shows that even for birds, the sense of smell is more important than previously thought.

Left brain vs. right brain – how we process faces
Scientists have used computer images which resemble a human face to show that the left and right sides of the brain process faces differently. While the left side of our brain signals the extent to which an image looks like a face, the right side makes distinct judgments – ‘face’ or ‘not-face’. In essence, the left interprets images in ‘shades of grey’ while the right does so in ‘black and white’.
