Geoscientists have identified a largely submerged landmass called Zealandia, or Te Riu-a-Māui, that meets the criteria many researchers use for a continent. Covering about 1.89 million square miles (roughly 4.9 million square kilometres), Zealandia is mostly underwater — about 90–95 percent — and includes the visible islands of New Zealand and New Caledonia. Debate about its status grew over decades and many geologists accepted it as a continent in analyses published in recent years.

As clocks move forward each spring across the northern hemisphere, debates over daylight saving time continue in several Western European countries. YouGov's Eurotrack survey asked people in Britain, Denmark, France, Germany, Italy, Spain and Sweden whether their country should stop switching clocks twice a year. Responses vary widely: 75% of Germans want to end the practice, while Italy is the only country where a majority (56%) prefers to keep changing the clocks. Britain and Spain were narrowly divided on the question.

In 1994 Pål Enger, a former Norwegian footballer, carried out a high-profile theft of Edvard Munch's famous painting The Scream from the National Gallery in Oslo. Enger entered the museum and removed the canvas in a theft that quickly made international headlines. The painting is one of Munch's best-known works, and its disappearance drew intense media and police attention because of its cultural significance and the bold manner in which it was taken.

The Loch Ness search, described as the biggest in fifty years, took place over the weekend at Scotland’s Loch Ness. The Loch Ness Centre partnered with Loch Ness Exploration to run the operation and invited volunteers to join boat patrols that ran from about 10 a.m. to 6 p.m. Organizers set up 17 official spotting points around the loch and asked the public to report any unusual sightings to the survey team.
