| Two volcanoes erupting in Alaska: Scientists are monitoring and providing alerts on Pavlof and Cleveland volcanoes Two of Alaska's most active volcanoes -- Pavlof and Cleveland -- are currently erupting. At the time of this post, their activity continues at low levels, but energetic explosions could occur without warning. Located close to the western end of the Alaska Peninsula, Pavlof is one of the most active volcanoes in the Aleutian arc, having erupted more than 40 times since the late 1700's. Driving and hands-free talking lead to spike in errors A pilot study shows driving while talking on a hands-free cellular device leads to more driving errors than driving alone. Students perform well regardless of reading print or digital books Students did equally well on a test whether reading from a digital book or a printed one, new research shows. Cosmic swirly straws: Galaxies fed by funnels of fuel Computer simulations of galaxies growing over billions of years have revealed a likely scenario for how they feed: a cosmic version of swirly straws. The results show that cold gas -- fuel for stars -- spirals into the cores of galaxies along filaments, rapidly making its way to their "guts." Once there, the gas is converted into new stars, and the galaxies bulk up in mass. Active or \'extremely active\' Atlantic hurricane season predicted for 2013 In its 2013 Atlantic hurricane season outlook issued today, NOAA's Climate Prediction Center is forecasting an active or extremely active season this year.

Research effort deep underground could sort out cosmic-scale mysteries Scientists have begun delivery of germanium-76 detectors to an underground laboratory in South Dakota in a team research effort that might explain the puzzling imbalance between matter and antimatter generated by the Big Bang. How playing surfaces affect athletic performance, injury potential Students have been jumping up and down for weeks on a variety of playing surfaces in a study to evaluate how each affects athletic performance and injury potential. The better to see you with: Scientists build record-setting metamaterial flat lens For the first time, scientists working at the National Institute of Standards and Technology (NIST) have demonstrated a new type of lens that bends and focuses ultraviolet (UV) light in such an unusual way that it can create ghostly, 3D images of objects that float in free space. The easy-to-build lens could lead to improved photolithography, nanoscale manipulation and manufacturing, and even high-resolution three-dimensional imaging, as well as a number of as-yet-unimagined applications in a diverse range of fields. |
