Expanded carrier screening: Is it worth it? Carrier screening tests would-be parents for hidden genetic mutations that might affect their children. It initially involved testing for specific genes in at-risk populations. Expanded carrier screening takes things further, giving would-be parents an option to test for a wide array of diseases in prospective parents and egg and sperm donors. The companies offering these screens "started out with 100 genes, and now some of them go up to 2,000," Sara Levene, genetics counsellor at Guided Genetics, said at a meeting I attended this week. "It's becoming a bit of an arms race amongst labs, to be honest."

Taiwanese politics increasingly revolves around one crucial question: Will China invade? China's ruling party has wanted to seize Taiwan for more than half a century. But in recent years, China's leader, Xi Jinping, has placed greater emphasis on the idea of "taking back" the island (which the Chinese Communist Party, or CCP, has never controlled). Many in Taiwan and elsewhere think one major deterrent has to do with the island's critical role in semiconductor manufacturing. Taiwan produces the majority of the world's semiconductors and more than 90% of the most advanced chips needed for AI applications.

Many in Taiwan and elsewhere think one major deterrent has to do with the island's critical role in semiconductor manufacturing. Taiwan produces the majority of the world's semiconductors and more than 90% of the most advanced chips needed for AI applications. Bloomberg Economics estimates that a blockade would cost the global economy, including China, 5 trillion in the first year alone. "The international community must certainly do everything in its power to avoid a conflict in the Taiwan Strait; there is too great a cost." The island, which is approximately the size of Maryland, owes its remarkably disproportionate chip dominance to the inventiveness and prowess of one company: Taiwan Semiconductor Manufacturing Company, or TSMC.
