    Scientists Say: Ferrofluid

    Ferrofluids are liquids with tiny magnetic particles in them. These liquids respond to magnets.

  2. Microbes

    Slimy fish could aid the search for new drugs

    Fish slime could teach scientists about bacteria that live on fish and aid in the hunt for new kinds of antibiotics.

  3. Environment

    Studies show how homes can pollute indoor air

    Cooking, cleaning, applying makeup or deodorant and other activities may sometimes leave indoor air as polluted — or worse — than outdoor air, new research suggests.

  4. Chemistry

    Remote-controlled nanoparticles could fight cancer — gently

    A new type of nanoparticle would keep toxic cancer drugs wrapped up so they won’t poison healthy cells. But a remote signal can unleash this cancer-killing medicine once it reaches a tumor.

  5. Physics

    Scientists now know why microwaved grapes make plasma fireballs

    Grapes trap microwave energy that bounces back and forth within the fruit. Until boom — a plasma!

  6. Chemistry

    Shape-shifting chemical is key to new solar battery

    Storing solar energy is a challenge. A new, shape-shifting molecule may provide a solution.

    Smartphone app helps researchers track art ‘acne’

    Metal soaps can form damaging blisters on the surface of oil paintings. Scientists are tracking these “breakouts” to protect priceless art.

  8. Chemistry

    Ham bone broth could be a tonic for the heart

    Health and fitness websites claim that drinking bone broth is a miracle cure. Here’s what some new research has to say about that.

  9. Earth

    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.
