A YouGov survey carried out in 27 countries finds the Covid-19 pandemic has had the most severe mental-health effects on young people and on women. Younger respondents consistently reported higher levels of anxiety about their mental health and increased worries about their financial futures, while women were more likely than men to say the pandemic had harmed their wellbeing. The findings summarize self-reported experiences rather than identifying precise causes.

Sarah Ogilvie’s The Dictionary People tells the story of the people who built the Oxford English Dictionary by collecting words, quotations, and regional usages. Ogilvie, a linguist, shows that the OED was not made by a single team in isolation but by thousands of volunteers who sent slips of paper and examples from newspapers, books, and everyday speech. The book explains how this wide network of contributors helped record English across time and place.

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.

Garry Kasparov, the Russian-born former world chess champion, has publicly endorsed Anatoly Fomenko’s “New Chronology,” a radical revision of world history. Fomenko’s thesis argues that much of what we call ancient history is misdated or duplicated and that the actual historical timeline is far shorter than commonly believed. Kasparov says he finds the questions it raises important and plans to spend more time promoting these ideas as he moves away from professional chess.
