  • New mirror picky in what it reflects

    Mirrors need not give you the full picture. A new type of mirror can pick and choose what to reflect. For instance, it can selectively reflect a single wavelength of light. All others pass right through — as if the mirror was transparent. Such technology could be used to create more efficient satellite antennas.Details appeared March 6 in the journal Physical Review Letters.The mirror is...

    SSP alums shine at 2015 White House Science Fair

    When it came to getting into the White House Science Fair, Holly Jackson had it all sewed up. Nikhil Behari, too, had just the right touch. And as for meeting President Barack Obama in person, it sent chills running up and down Harry Paul’s spine.“No pun intended,” says Paul, who along with Jackson and Behari, was among the more than 100 students invited to exhibit at the fifth White House...

  • Why you’ll never see a dirty gecko

    If you ever wear a self-cleaning jacket one day — and you may — it could have been inspired by a frozen lizard. A gecko, to be exact.Australian scientist Jolanta Watson had removed the carcass of a box-patterned gecko from her lab’s freezer to prepare it for an experiment. As she looked at it, she noticed tiny water droplets forming all over the gecko’s skin. Quickly, the droplets got bigger....

  • 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...
