Five years in the coldest fridge in the known Universe

00:46 The very cool experiment looking for a proposed particlePhysics tells us that when matter is created, antimatter should be as well. But while the Universe is full of matter, there’s surprisingly little antimatter to be found. To try and understand this imbalance, a team have built a detector kept just above absolute zero which they are using to look for a hypothesised, ultra-rare type of particle decay that could create matter without antimatter.Research article: The CUORE CollaborationNews and Views: Cryogenic mastery aids bid to spot matter creation09:43 Research HighlightsSubsidence of coastal cities makes them more vulnerable to sea-level rise, and tackling ‘crazy ants’ with a parasitic fungus.Research Highlight: Global cities are sinking — and humans are partly to blameResearch Highlight: Marauding crazy ants come to grief when a fungus comes to call12:17 Solving the puzzle of the missing plasmidsBacteria are well known for their ability to share genes, which they often do using small circles of DNA called plasmids. But while plasmids are common in bacteria, a long-standing mystery has been why they are absent in a group of cholera-causing strains of Vibrio cholerae. Now, a team might have solved this mystery, by discovering two previously unknown DNA defence systems that eliminate plasmids, hidden in the bacteria's genomes.Research article: Jaskólska et al.News and Views: Bacterial defence systems degrade plasmid invaders18:41 Briefing ChatWe discuss some...
