In the French phrase 'faire bonne chère', to eat well, 'chère' has nothing to do with 'chair', flesh. It comes from Late Latin 'cara', face. In Old French, to 'faire bonne chère' to someone meant to show them a friendly face, to welcome them warmly. Since a warm welcome usually came with a good meal, the phrase drifted towards fine dining, keeping its puzzling spelling.
In Kuşköy, a mountain village in northern Turkey, people talk across valleys by whistling Turkish. A 2015 study showed that whistled Turkish draws on both hemispheres fairly evenly, whereas spoken Turkish relies mostly on the left. The physical form of the signal, it turns out, matters to the brain.
Speech has no gaps between words. In 1996, researchers played 8-month-old babies a continuous stream of made-up syllables for just two minutes. The infants picked out the 'words' by tracking which syllables tend to follow one another. That's probability calculation, done without a calculator or any visible effort.
