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.

CPAC Hungary, the Budapest edition of the Conservative Political Action Conference, gathered American and European conservative activists, politicians, and commentators to discuss what organizers called the decline of Western civilization. Sessions focused on immigration, resistance to progressive social policies, and critiques of liberal democracy. Hungary’s prime minister Viktor Orbán was a prominent speaker, and some remarks echoed the “great replacement” language while emphasizing national sovereignty and cultural preservation.

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.

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.
