  • The True Color of Ancient Sea Creatures
    2014-01-12 09:55:22 UTC

    Looking a bit like a dolphin, but with a long slim snout filled with pointy teeth, one species of ichthyosaur was practically invisible in the murky depths of Jurassic seas, thanks to dark pigmentation that covered its entire body. That’s one conclusion of a new study that provides an unprecedented peek at the coloration of sea creatur...
  • Bacteria Lay Out Welcome Mat for Tubeworms
    2014-01-12 09:49:23 UTC

    Although they remain firmly attached to rocks on the sea floor and other surfaces for most of their lives, ocean-dwelling tubeworms spend their early days as free-swimming larvae, looking for a place to call home. A key factor in their decision to latch on somewhere is the presence of certain bacteria. Now, researchers have discovered ...

  • To grow or to defend: How plants decide
    2014-01-02 07:21:16 UTC

The findings published in the open-access scientific journal eLife could be used to engineer crops that combine size with pathogen resistance. "A major dilemma faced by plants is whether to invest their energy ...
  • Global temperatures to rise at least 4°C by 2100
    2014-01-02 07:10:01 UTC

    Global average temperatures will rise at least 4°C by 2100 and potentially more than 8°C by 2200 if carbon dioxide emissions are not reduced according to new research published in Nature. Scientists found global climate is more sensitive to carbon dioxide than most previous estimates. The research also appears to solve one of the great...

  • Why It Snows So Much in the Frozen North
    2013-12-21 07:14:08 UTC

    When it doesn't show signs of stopping, most of us just mumble a few choice words and get out the snow shovel. Scientists, however, wonder where all that snow is coming from, particularly in pristine places like the Arctic. Raymond Shaw and his colleagues may have found an answer. Here's the conundrum: Snow doesn't just materialize ...
