The most dangerous delivery truck? How a lorry-load of antimatter will help solve secrets of universe

Fantastically expensive and hard to handle, the substance holds the key to a holy grail of science. And experts at Cern now know how to transport it

Researchers are preparing to make one of science's most unusual journeys. They are planning to transport a container of antimatter in a lorry across Europe.

Antimatter is the most expensive material on Earth - it's estimated it would cost several trillion dollars to make a gram - and it can only be manufactured in particle physics laboratories such as the Cern research centre near Geneva.
