    Why Beans Make You Fart

    Not fiber, and not beans simply being hard to digest. They carry three sugars your small intestine cannot break down, because it makes none of the enzyme required. Those sugars reach your colon intact, where billions of bacteria do have it. The gas isn't your digestion failing. And they dissolve readily in water.

    Why You Can't See Clearly Underwater

    Blame usually lands on the chlorine, or on the water not being clear enough. The trouble is in your eye, in the part nobody thinks about. Two-thirds of its focusing power comes from the cornea, and that only works with air sitting in front of it. A mask mainly puts the air back.

    Why Growers Coat Fruit Blossom in Ice to Save It From Frost

    An April night, the trees in blossom, the temperature dropping toward twenty-eight. The grower goes out, turns on the irrigation and leaves it running until morning.

    Why Alcohol Makes You Feel Warm and Puts You in Danger

    The warmth is real, and it is heat on its way out. Your temperature sensors sit in your skin, reporting honestly on what they measure, which is warm blood arriving at exactly the surface a body loses heat through. Meanwhile the emergency system that would make heat gets delayed.

    Why Gold, and Not Some Other Metal

    Walk the periodic table with one requirement, something to store value in, and rule out the gases, anything that rusts or burns, anything radioactive, anything too common or too rare. Five neighbors are left. Chemistry stops being enough there. What decides among them is ancient furnaces and what hands could actually work.

    Why Asparagus Changes the Smell of Your Pee

    Half the table has no idea what you are talking about. The usual explanation puts the difference in who produces the smell. The best-documented difference is in the nose: nearly seven thousand people surveyed, then their DNA read, variants clustering near smell-receptor genes. Differences in production are not ruled out.
