Polar ecology lesson: South Georgia’s invasive reindeer story gets a scientific spotlight, with researchers describing how nearly 7,000 animals were removed after a century of unchecked growth damaged native vegetation. Ocean chemistry and extinction: New research links ancient ocean acidification to a major Cretaceous extinction, using chemical clues from microscopic fossils to show how volcanic CO2 reshaped seawater and harmed shell-building plankton. Aviation and skills in the Falklands orbit: The RAF is set to return to Enniskillen for the RAF Town Show, featuring a Typhoon and highlighting the aircraft’s role in Quick Reaction Alert missions that include the Falkland Islands. Heritage tech meets military history: Portsmouth Historic Dockyard’s £15m Royal Marines Experience opens 24 October, using VR/AR and real objects (including Falklands-era kit) to bring 360+ years of Royal Marines history to life. Local science-adjacent community note: Uruguay’s Expo Prado opens with a big livestock and agro-industrial programme, including Falklands delegations returning to the event.
