Scientists are 'baffled' by strange cloud-like plumes spotted 250km above the surface of Mars. Genetic analysis shows penguins can only taste salty and sour things, and they lost the other taste receptors a long time ago. Drinking three cups of coffee could reduce DNA strand breakages, which could lead to a lower risk of cancer and other illnesses. A NASA animation shows a high-tech submarine concept that could one day explore the liquid methane oceans on Saturn's moon Titan. One day in the very distant future. Maybe. A new study suggests that sugary soft-drinks could be part of the reason girls are starting their periods at a slightly earlier age.
