    A really cool map

    This infrared image of Saturn's rings, released by NASA on Sept. 2, provides the most detailed temperature map ever taken of the icy particles encircling the planet.

    Taken by the Cassini spacecraft on July 1, the false-color image shows the unlit surface of the rings, where temperatures vary from 70 kelvins (blue) to 110 kelvins (red). Water freezes at 273 kelvins. The...

    Super Bird: Cooing doves flex extra-fast muscles

    The power behind a ring dove's trill belongs to the fastest class of vertebrate muscles known, reports a team of physiologists. This is the first demonstration of superfast muscles in a bird, the researchers say.

    These muscles contract some 10 times as fast as the muscles that vertebrates typically use for running, says Coen Elemans of Wageningen University in the Netherlands....

    A Very Spatial Brain Defect: Gene disorder blocks neural path for vision

    Among its many unusual symptoms, the genetic disorder called Williams syndrome robs people of depth perception and the ability to visualize how different parts assemble into larger objects, as in a simple jigsaw puzzle.

    An unusual scarcity of tissue in a small corner of the visual system underlies this particular problem in individuals with Williams syndrome, a new brain-imaging study...

    Falling into Place: Atom mist yields nanobricks and mortar

    Nanotechnologists envision using tiny structures to create ultrastrong materials and to build memory chips that store entire libraries. But these visions require making matter behave in exceptionally orderly ways.

    Now, materials scientists Jagdish Narayan and Ashutosh Tiwari of North Carolina State University (NCSU) in Raleigh have induced tiny particles, or nanodots, of...

    An Exploitable Mutation: Defect might make some lung cancers treatable

    Nonsmokers who develop lung cancer are more likely than their smoking counterparts to have a mutation in a gene called EGFR, a new study shows. The discovery could be good news for these nonsmokers because tumors that have this genetic defect—which fosters aberrant cell growth—appear highly responsive to a drug called gefitinib.

    The findings have already triggered genetic screening to...
