Lots of huffing-and-puffing from volcanoes around the world, all wrapped up neatly in this week's USGS/SI Volcano Activity Report.

The latest news from the USGS/Smithsonian Global Volcanism Program Weekly Volcano Report ...

    Surprising Science
    • Athelstan Spilhaus designed an oceanic thermometer to fight the Nazis, and the weather balloon that got mistaken for a UFO in Roswell.
    • In 1942, he produced a world map with a unique perspective, presenting the world's oceans as one body of water.

    Major study: Drug overdoses over a 38-year period reveal hidden trends

    It's just the current cycle that involves opiates, but methamphetamine, cocaine, and others have caused the trajectory of overdoses to head the same direction

    From the study:
    Surprising Science
    • It appears that overdoses are increasing exponentially, no matter the drug itself
    • If the study bears out, it means that even reducing opiates will not slow the trajectory.
    • The causes of these trends remain obscure, but near the end of the write-up about the study, a hint might be apparent
