  • 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. A recent study published in Nature Communications is the latest impetus for headlines like “Italian Supervolcano Might Be on the Verge of Exploding” or...
  • 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...
  • The Great Lie of American Flood Risk

    MILLIONS OF AMERICANS are living a lie. You might be one of them: The homeowners who live near a flooding California river, the landlords in a slowly subsiding Southern city, or the business operators on a shoreline inundated a Nor’Easter’s storm surge. And all around the country, the federal...
  • Devastation detectives try to solve dinosaur disappearance

    Below the shimmering turquoise waters of Mexico’s Yucatán Peninsula lies the scene of a prehistoric mass murder. In a geologic instant, most animal and plant species perished. Drilling through hundreds of meters of rock, investigators have finally reached the footprint left by the accused: Earth’s most notorious space rock...
  • Life On Mars: Astrobiologists Prove Microbes Can Survive The Thin Martian Atmosphere

    The news concerning Mars’ capability to sustain living organisms just got better. Astrobiologists now say that microbes can survive the harsh parameters of the thin atmosphere on the Red Planet. In fact, a new study has determined that certain microbes, if given the opportunity to proliferate in areas on...
