Chemistry-informed advice for cooking pasta, including how to prevent clumping noodles

On a molecular level, pasta dough consists of protein structures that hold starch molecules, and the starches absorb water during cooking, forming a gel that softens the pasta. Pasta should not be rinsed after cooking. Instead, some of the pasta water should be added to the pasta sauce, as the gelatinous starch will help the sauce stick to the pasta.

How radio works

Antennae tune a radio to a particular frequency (determined by the listener on their radio's dial) while tuning out all the other stations being broadcast. AM, short for amplitude modulation, and FM, short for frequency modulation, decode audio signals differently, leading to differences in sound quality and the distance a station can travel.
