Waves and ripples in the Earth can reveal the location and depth of an explosion
  • How Climate Change Is Already Affecting Earth

    Though the planet has only warmed by one-degree Celsius since the Industrial Revolution, climate change’s effect on earth has been anything but subtle. Here are some of the most astonishing developments over the past few years....
  • Stephen Hawking: Trump Pushing Earth’s Climate ‘Over The Brink’

    The world’s best-known living physicist, Stephen Hawking, says that President Trump’s decision to pull out of the Paris climate change accord could lead humanity to a tipping point, “turning the Earth into Venus.” The Cambridge professor and renowned cosmologist made the remarks in an interview with the BBC that aired Sunday....
  • Incredible New Observation Shows Supermassive Black Holes Orbiting Each Other

    You think our galaxy is special? Ha. Our boring pinwheel of gas and dark matter might be a nice hangout for humans. But 750 or so million light years away, there’s an elliptical galaxy, Galaxy 0402+379, whose two supermassive black holes are orbiting each other from a distance of...
  • Look, kids! Science!

    In my very first Experimental Error column in 2010, I made fun of standard science demonstrations, especially one I called “Let’s All Gawk at Liquid Nitrogen.” Why, I complained, were certain experiments so universal, especially when they showed nothing about what scientists actually do? Now, 7 years and 82...
  • Molecular system for artificial photosynthesis

    Photosystems (PS) I and II are large protein complexes that contain light-absorbing pigment molecules needed for photosynthesis. PS II captures energy from sunlight to extract electrons from water molecules, splitting water into oxygen and hydrogen ions (H+) and producing chemical energy in the form of ATP. PS I uses...
  • Everyone Stop Freaking Out Over Italy’s Super volcano

    YELLOWSTONE USED TO be the favored target of media volcano panic, but now it looks like Italy’s Campi Flegrei has taken that crown for itself.

  • Just another fake: US could face magnitude 9 earthquake within DAYS sparking tsunami, quake mystic claims

    A self-styled earthquake predictor is warning of a magnitude seven, eight or nine quake hitting the planet between now and May 12. ‘Quake mystic’ Frank Hoogerbeets has issued an online “major earthquake warning” amid fears a “big one” is on its way, claiming it could also cause a tsunami....
  • Homo naledi species discovery raises fresh questions about evolution

    Scientists unveiled the first evidence on Tuesday that early humans co-existed in Africa 300,000 years ago with a small-brained human-like species thought to already be extinct on the continent at that time. The findings, published in three papers in the journal eLife, raise fresh questions about human evolution, including...
  • ALMA Investigates ‘DeeDee,’ a Distant, Dim Member of Our Solar System

    At about three times the current distance of Pluto from the #Sun ,  DeeDee is the second most distant known trans-Neptunian object (TNO) with a confirmed orbit, surpassed only by the dwarf #planet Eris. Astronomers estimate that there are tens-of-thousands of these icy bodies in the outer solar system...
