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.

A recent poll of 2,000 British adults found many people follow celebrity news more closely than the lives of family and friends. Forty-four percent said they cared about trivial celebrity matters, and 80% admitted they knew more about celebrities than their own parents. Nearly half reported knowing more about famous people than about their friends. Sixty-one percent believe the media spends too much time on celebrity coverage.

A Kansas judge has ordered authorities to delete all electronic copies made from files seized during a police search of the Marion County Record, a small local newspaper. The searches, carried out nearly two weeks earlier, removed computers and cellphones from the paper’s office. The court order requires that digital copies created from those devices be destroyed, limiting how officials may keep and use material gathered in the raid.

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.
