Laser-cooled antimatter opens up new physics experiments, and the staggering economic cost of invasive species.
In this episode:
00:44 Cooling antimatter with a laser focus
Antimatter is annihilated whenever it interacts with regular matter, which makes it tough for physicists to investigate. Now though, a team at CERN have developed a way to trap and cool antihydrogen atoms using lasers, allowing them to better study its properties.

Research Highlight: Rabbits that do ‘handstands’ help to find a gene for hopping
11:53 Cost of invasion
Invasive alien species are organisms that end up in places where they don’t really belong, usually as a result of human activity. These species can cause loss of biodiversity and a host of damage to their new environments. This week, researchers estimate that the economic impact of invasive species to be over US $1 trillion.
