    Why we should stop ignoring the life stories of minerals

    All pure diamonds are the same mineral. But they didn’t form the same way. One scientist thinks it’s time to talk about the life stories of such rocks.

    Big rock candy science

    Instructions for making your own rock candy say to dip your stick or string in sugar before putting it in your sugar solution. Does that matter?

    Shell shocked: Emerging impacts of our acidifying seas

    As Earth’s climate changes, the oceans are becoming more acidic. Here’s how oysters and reefs are responding to their acidifying bath.

  4. Plants

    This houseplant can clean indoor air

    Houseplants may be able to help clean up polluted indoor air. Scientists gave this one a boost by givng it a gene from a rabbit.

  5. Materials Science

    Scientists Say: Zirconium

    Zirconium is a metal that knows the meaning of tough. It’s so heat resistant that it’s used for molds to shape melted metals, and so radiation resistant that it coats nuclear reactors.

    This rewritable paper depends on disappearing ink

    Scientists have made a new rewritable paper that can hold text and images for at least six months. It also can be reused more than 100 times.

    Some plastics learn to repair themselves

    A new material can fix its own scratches and small cracks. One day, it also may make self-healing paints and plastics possible.

    Explainer: How is water cleaned up for drinking

    Unless you’re drinking well water, city folks typically get drinking water that has been treated in a water-treatment plant. Here’s what that means.

    Super-water-repellent surfaces can generate energy

    Scientists knew they could get power by running salt water over an electrically charged surface. But making that surface super-water-repellent boosts that energy production, new data show.
