  • Goopy tech leaves older 3-D printing in its wake

    A movie robot made of liquid metal that could take on any shape has inspired researchers to print three-dimensional objects from a puddle of goo.The new 3-D printing method manipulates ultraviolet (UV) light and oxygen to fuse liquid resin into solid objects. Those objects rise out of a shallow basin of resin in just minutes. That is far less time than required with conventional 3-D printers. The...

  • Silencing genes — to understand them

    The DNA in each of us hosts about 21,000 genes. Their blueprints are coded in the roughly 3 billion rungs of our DNA’s ladder-like structure. The Human Genome Project finished decoding all of those genes in 2003. That task took hundreds of scientists more than 12 years.Scientists are now working fast and furiously to learn what each identified gene does. Their answers will help science better...

  • QUESTIONS for Silencing Genes

    SCIENCEBefore reading1.    Everybody has the same number and the same types of genes. But each of those genes can vary somewhat. List some ways those variations can show up in the differing appearances of you and your friends.During reading1.    How many genes do we have?2.    What does RNAi turn off?3.    What do A, T, C and G stand for?4.    Where might you find uracil?5.    What does “express...

    Cookie Science 14: One experiment, 400 cookies

    Several friends and I recently spent more than eight hours straight in the kitchen. We weren’t making an elaborate dinner or trying out new recipes. We were doing research. It just happened to require baking more than 400 cookies.My goal never really had been to make 400 cookies. I wanted to create just one, a treat for a friend who can’t stomach the gluten proteins found in wheat. I had recently...

  • Life’s ultra-slow lane is deep beneath the sea

    Near the edge of continents, seafloor sediments teem with oxygen-breathing microbes. They live large on the feast of nutrients that wash off the land. They live so well, in fact, that they sometimes use up all the oxygen in the sediment. But what about places that are far from continents? With no source of nutrients, these distant, deep sea zones were largely dead. Or at least that's what...

  • Explainer: Understanding plate tectonics

    For billions of years, Earth has been remodeling itself. Huge masses of molten rock rise from deep inside Earth, cool into a solid, travel along our planet’s surface and then sink back down. The process is known as plate tectonics.The term tectonics comes from a Greek word meaning “to build.” Tectonic plates are huge moving slabs that together make up Earth’s outer layer. Some span thousands of...

  • Arctic warming bolsters summer heat

    Sweltering summer heat waves are on the rise across the Northern Hemisphere. The rise is being driven by changes in the atmosphere spurred by a warming Arctic, new research shows.Scientists came to that conclusion after examining 35 years of weather data. They spotted a decline in the strength of summer storms. These storms bring welcome relief to northern continents in the form of cool, moist...

    Teen helps plants fight off pests

    WASHINGTON, D.C. – Farming is a risky business. Every year, farmers lose some of their crops to chewing insects, invading fungi or hungry worms. Plants often are helpless to fight back. And if the crops die, it’s a big loss for the farmer and for the people who want healthy, affordable foods. Now, a teen has studied ways to use an invading worm’s own weapons against it, giving crops a chance to...

  • 3-D Recycling: Grind, melt, print!

    Three-dimensional, or 3-D, printers make it possible to “print” almost any object with a computer. The machines produce items by laying down tiny drops, or pixels, of material one layer at a time. That material can be made from plastic, metal or even human cells. But just as the ink for standard computer printers can be expensive, 3-D printer “ink” can be quite pricey too. Meanwhile, society...
