Matter and Its Interactions

  1. Agriculture

    Potty-trained cows could help reduce pollution

    About a dozen calves have been trained to pee in a stall. Toilet training cows on a large scale could cut down on pollution, scientists say.

    Scientists Say: Electron

    Electrons are negatively charged particles. They are attracted to the positively charged particles in the center, or nucleus, of an atom.

    Chemists win Nobel Prize for faster, cleaner way of making molecules

    Both scientists independently came up with new process — asymmetric organocatalysis. That name may be a mouthful, but it’s not that hard to understand.

    Well-known wildflower turns out to be a secret meat-eater

    Look closely at Triantha occidentalis, and you’ll see gluey hairs — and a trail of insect corpses on its stem.

    Synthetic trees could tap underground water in arid areas

    They also could also help coastal residents mine fresh water from salty sources.

    Scientists Say: Plasma

    In physics, plasma refers to one of the four states of matter. In medicine, plasma describes the part of blood that ferries cells, nutrients and more throughout the body.

    New glue offers to turn any small walking robot into Spider-Man

    To climb walls, robot feet need to alternately stick and let go. A novel adhesive can do that. Its stickiness is controlled by electric fields.
