Episode notes

The global cost is really enormous in terms of billions. It's one thousand and 300 in the last 50 years. And on average per year, as several tousand billions. In the end, in two thousand 17, the last year for which we have an estimate, it's over 160 billion dollars.

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.

09:27 Research Highlights

A dramatic increase in Arctic lightning strikes, and an acrobatic bunny helps researchers understand hopping.

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.

19:04 Briefing Chat

We discuss some highlights from the Nature Briefing. This time, the physics that might explain how a ship blocked the Suez Canal, and a new insight into octopuses’ sleep patterns.
