Researchers studying more than 15,000 people report that higher physical fitness is linked to a lower chance of developing atrial fibrillation, an irregular heartbeat that raises the risk of stroke fivefold. The study, presented at the ESC Congress 2023, used treadmill exercise tests to estimate fitness in metabolic equivalents (METs) and followed participants over time to see who developed heart rhythm problems or strokes.

Meta announced it has closed nearly 9,000 Facebook and Instagram accounts linked to a Chinese political influence operation called 'Spamouflage.' The company says the network posted material that praised China while criticizing the United States, Western governments, and outspoken critics of the Chinese government. Meta removed the accounts after an investigation that identified coordinated posting patterns and account connections tied to operators in China, calling the activity inauthentic and aimed at manipulating online discussion.

Linguists have long thought that social context shapes grammar: communities with many non-native speakers, like trade hubs, were believed to favor simpler, easier-to-learn systems, while isolated, homogenous groups develop dense, specialized grammatical rules. A new study compiled measurements across about 1,300 languages to test whether languages used mainly by “societies of strangers” indeed show reduced grammatical complexity compared with languages used in more stable, insider communities.

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.
