<h2>00:46 How fishing activity altered the migration pattern of Herring</h2>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.Research article:&nbsp;<a href="https://www.nature.com/articles/s41586-025-08983-3" rel="noopener noreferrer" target="_blank">Slotte et al.</a><h2>10:37 Research Highlights</h2>Archaeologists have identified tools that the ancient Maya may have used for tattooing, and the self-assembling stable structures that may help ‘forever chemicals’ persist in nature.Research Highlight:&nbsp;<a href="https://www.nature.com/articles/d41586-025-01324-4" rel="noopener noreferrer" target="_blank">Tattoo-making tools used by ancient Maya revealed</a>Research Highlight:&nbsp;<a href="https://www.nature.com/articles/d41586-025-01385-5" rel="noopener noreferrer" target="_blank">‘Forever’ molecules bunch themselves into cell-like structures</a><h2>13:02 How might AI companions affect users’ mental health?</h2>AI companions — apps where humans build relationships with computers — are hugely popular, with millions of people around the world using them.
