    Scientists Say: Absolute zero

     Absolute zero (noun, “AB-so-loot ZEE-ro”)This is the coldest possible temperature. It is zero on the kelvin scale, which is also -273.15° Celsius (-459.67° Fahrenheit). The temperature of a sample depends on how quickly the atoms or molecules in it are moving relative to each other. What we call ice is water molecules moving very slowly, in a matrix. Water molecules moving very quickly become...

    Science fairs sharpen storytelling

    While Cristina Costantini didn't become a scientist, she's used the skills she gained through science fairs to become an award-winning investigative journalist. She was an Intel ISEF 2004 and 2005 finalist.Competing in science fairs doesn’t mean you’ll end up as a scientist, Cristina said. "But those skills will be with you for a long time. They help in ways we don’t even understand in middle and...

  • Polar bears swim for days as sea ice retreats

    Polar bears are excellent long-distance swimmers. Some can travel for days at a time, with only very short rest stops on ice flows. But even polar bears have their limits. Now a study finds they are swimming longer distances in years with the least amount of Arctic sea ice. And that worries Arctic researchers.Swimming a long time in cold water takes a lot of energy. Polar bears can tire and lose...

  • Teens invent way to keep floodwaters out of subways

    PHOENIX, Ariz. —Superstorm Sandy slammed into the Eastern United States 3.5 years ago. It pummeled New York City with hurricane-force winds. In some places, the gales drove rising tides much farther onshore than normal. That wind-driven water, or storm surge, caused a lot of flooding, especially in the region’s subway system. Now, two teens have invented a device that could help prevent future...

    Male peacocks know how to twerk it to attract peahens.During mating season, the flamboyant males really put on a show. Each will raise his iridescent train, shake his wings and vibrate his fan. Such displays can go on for hours.A group of researchers wanted to break down the basic biomechanics of this shimmy show. It is known as “rattling.” The team included Roslyn Dakin. She is at biologist at...

  • Common water pollutants hurt freshwater organisms

    PHOENIX, Ariz. — People are constantly releasing new pollutants into the watery environment. Some may be bits of plastic we can see. Others may be chemicals that wash down the drain or get flushed down the toilet. We may not see those chemicals, but three teens have shown that some polluting wastes can harm freshwater organisms, such as water fleas. But even these can play important roles in...
