Researchers have developed a portable antimatter containment device and tested it by putting it in a truck and driving it around CERN. Their system could represent a big step forward in efforts to take particles made at CERN’s ‘antimatter factory’ and transport them to other labs, something currently impossible due to antimatter being destroyed upon contact with matter. The team showed the feasibility of their approach by using the system to safely transport particles of matter and are now looking to adapt it to ferry antimatter particles.

How a tradition of female diving on a South Korean island might have shaped the genomes of the island’s population, and a poison-dart frog that curiously seems to be monogamous.

Physicists have tackled a longstanding problem in physics — understanding how two black holes gravitationally interact as they fly past each other — which could help with future detections of the gravitational waves that would be created by these events. Rather than repeatedly running expensive computer simulations to approximate the answer to this problem, a team of theorists have come up with a mathematical formula to describe a black hole fly-by, which can be run in a matter of seconds. Their results could be used to identify the tell-tale signatures of these events when they actually occur.

In this Podcast Extra, we examine recent developments US National Science Foundation, which has seen significant numbers of research grants terminated. In addition, there have been freezes on funding for new grants and any additional money to existing ones. We also discuss US President Donald Trump’s proposed budget for fiscal year 2026, which calls for disproportionately large cuts to federal science funding.

Selective fishing of older herring has resulted in a large shift in the migration pattern of these fish, according to new research. For years, herring have visited sites on the south coast of Norway to spawn, but in 2020 a rapid shift was seen, with the fish instead visiting areas hundreds of kilometres to the north. Researchers have concluded that too many older fish have been removed from these waters, preventing the knowledge of the best spawning grounds being passed to younger, less experienced fish. This finding shows how human activity can affect animal migration, which could have serious consequences for the delicately balanced ecosystems built around them.

AI companions — apps where humans build relationships with computers — are hugely popular, with millions of people around the world using them. But despite increased social and political attention, research investigating how these systems can affect users has been lacking. We find out about the latest research in this space.
