Higgs boson scientists win Nobel prize

Peter Higgs, from the UK, and Francois Englert from Belgium, share the prize.

In the 1960s, they were among several physicists who proposed a mechanism to explain why the most basic building blocks of the Universe have mass.

The mechanism predicts a particle - the Higgs boson - which was finally discovered in 2012 at the Large Hadron Collider (LHC) at Cern, in Switzerland.

The boson explains why other elementary particles - the basic building blocks of the Universe - have mass.

"This year's prize is about something small that makes all the difference," said Staffan Normark, permanent secretary of the Royal Swedish Academy of Sciences.

Nasa plans 3D printer space launch

3D printer
US space agency Nasa is planning to launch a 3D printer into space next year to help astronauts manufacture spare parts and tools in zero gravity.

It will be the first time a 3D printer has been used in space and could help reduce the costs of future missions.

The device will have to withstand lift-off vibrations and operate safely in an enclosed space station environment.

Nasa has chosen technology start-up Made in Space to make the microwave oven-sized printer.

"Imagine an astronaut needing to make a life-or-death repair on the International Space Station," said Aaron Kemmer, the company's chief executive.

"Rather than hoping that the necessary parts and tools are on the station already, what if the parts could be 3D printed when they needed them?"

In 1970, Apollo 13 astronauts had to cobble together a home-made carbon dioxide filter using a plastic bag, a manual cover and gaffer tape. A 3D printer might have solved the problem in minutes.
