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 focusAntimatter 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 Article: Baker et al.News and Views: Antimatter cooled by laser light09:27 Research HighlightsA dramatic increase in Arctic lightning strikes, and an acrobatic bunny helps researchers understand hopping.Research Highlight: Rising temperatures spark boom in Arctic lightningResearch Highlight: Rabbits that do ‘handstands’ help to find a gene for hopping11:53 Cost of invasionInvasive 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.Research Article: Diagne et al.19:04 Briefing ChatWe discuss some highlights from the Nature Briefing.
