The smallest planet in the Solar System has become even smaller, studies by the Messenger spacecraft have shown.

One starfish has a remarkable strategy to avoid overheating in the sun, scientists have discovered. The starfish pumps itself up with cold seawater to lower its body temperature when exposed to the sun at low tide. It is equivalent to a person drinking seven litres of water before heading into the midday sun, scientists say.

Slowly but surely an extinct glacier in a remote corner of the Peruvian Andes is being returned to its former colour, not by falling snow or regenerated ice sheets, but by whitewash.

A pioneering research effort could shrink the world's most powerful supercomputer processors to the size of a sugar cube, IBM scientists say. The approach will see many computer processors stacked on top of one another, cooling them with water flowing between each one. The aim is to reduce computers' energy use, rather than just to shrink them. Some 2% of the world's total energy is consumed by building and running computer...

Japan says it is stepping up efforts to cool overheating fuel at the tsunami-hit Fukushima Daiichi nuclear plant. Army helicopters dumped tonnes of water to try to prevent a meltdown of fuel rods. Water cannon are set to join the operation on the ground and it is hoped electricity will be restored soon.

A group of more than 200 Japanese pensioners are volunteering to tackle the nuclear crisis at the Fukushima power station. The Skilled Veterans Corps, as they call themselves, is made up of retired engineers and other professionals, all over the age of 60. They say they should be facing the dangers of radiation, not the young.

Over a 1000-km run, superconducting cables can carry far more power than cables of a comparable size. Even taking into account the energy required to cool them, they lose just a third as much energy in transmission. Just as in the case of optical fibres, the technology has been quietly refined over the years and in some senses is ready to be deployed. This will be costly at first, but with tangible benefits that the wider market may just...
