Imagine you had a friend who gave different answers to the same question, depending on how you asked it. “What’s the capital of Peru?” would get one answer, and “Is Lima the capital of Peru?” would get another. You’d probably be a little worried about your friend’s mental faculties, and you’d almost certainly find it… Continue reading Game Theory Can Make AI More Correct and Efficient

How ‘Idle’ Egg Cells Defend Their DNA From Damage
Having lots of mitochondria is normally risky for cells because their chemical activity generates toxic byproducts known as free radicals. But when Böke peered inside dormant human and frog oocytes, they weren’t overloaded with free radicals at all. As she reported in a Nature paper published in 2022, the oocytes’ mitochondria were doing something surprising:… Continue reading How ‘Idle’ Egg Cells Defend Their DNA From Damage
Strangely Curved Shapes Break 50-Year-Old Geometry Conjecture
In an old Indian parable, six blind men each touch a different part of an elephant. They disagree about what the elephant must look like: Is it smooth or rough? Is it like a snake (so thinks the man touching the trunk) or a fan (as the man touching the ear proposes)? If the blind… Continue reading Strangely Curved Shapes Break 50-Year-Old Geometry Conjecture
Vaccine-resistant Mothers Blame Bad Experiences in Health Care

Popular writing on vaccine skepticism often denigrates white and middle-class mothers who reject some or all recommended vaccines as hysterical, misinformed, zealous or ignorant. Mainstream media… Continue reading Vaccine-resistant Mothers Blame Bad Experiences in Health Care
Computer Scientists Invent an Efficient New Way to Count
Let’s return to Hamlet, but this time your working memory — consisting of a whiteboard — has room for just 100 words. Once the play starts, you write down the first 100 words you hear, again skipping any repeats. When the space is full, press pause and flip a coin for each word. Heads, and… Continue reading Computer Scientists Invent an Efficient New Way to Count
