We highlight some Nature Briefing stories from the end of 2025, including: a seismic detector made from a telecom cable, and how self-heating plants attract pollinators.

00:54 Turning an undersea cable into a seismic detector
Researchers have shown that they can piggyback a signal on a 4,400-kilometer-long telecom cable that runs from California to Hawaii, allowing it to act like 44,000 separate seismic-activity detectors. Their method takes advantage of impurities found in glass fibre-optic cables, which reflect light differently when they are stretched and distorted by the pressure of seismic waves.

04:17 The origin of an ancient boat
Chemical analysis of the caulking found on the wood an ancient boat has helped researchers identify the origins of the vessel, that sank off the coast of Denmark 2,400 years ago. The team’s analysis suggests it voyaged from much farther away that had been thought — perhaps coming from the Baltic Sea region. The team also found a fingerprint left in the caulk, although who it belonged to is unknown.
