Hangovers seem to be caused by the presence of acetaldehyde in your bloodstream. The ability to metabolize acetaldehyde is controlled by a gene named ALDH2, which is present in mutant form in many Asians.

The curse of technology – you just have to keep upgrading for better performance. And this applies not only to your fruit-branded laptop (eh, Jeremy?) – the Mars rover robots need upgrades and software updates too.

The Moon has no magnetic field like Earth’s, which means that anyone spending a long time there is going to be bombarded with a whole lot of radiation from the Sun.

Stenocara beetles live in the Namib Desert, one of the driest places on Earth, and have had to evolve effective methods of capturing water. A team of researchers have created a composite nanomaterial that collects airborne water from mist and fog based on the mechanism used by the beetle, which is much more effective than current mist-nets.
