A recent YouGov–Cambridge Globalism Project survey finds that voters in Western democracies are more divided by identity and partisan loyalty than by specific policy positions. Researchers describe strong "affective polarization": people feel intense dislike for opposing groups even when those groups often share similar views on key debates such as sexism, racism, and economic policy. The findings challenge the idea that culture wars are mainly about conflicting opinions; instead, much conflict appears driven by who people see as "us" versus "them."

China's Chang'e-4 lander touched down on the Moon's far side in January 2019. Using instruments including ground-penetrating radar, the mission collected subsurface profiles near its landing site. A team writing in the Journal of Geophysical Research: Planets reports the top roughly 130 feet (about 40 metres) of the surface is layered—alternating dust, soil and broken rock—and that a buried impact crater lies within those layers.

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.

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.
