  • VIDEO | Ancient human, giant sloth remains found in world’s biggest flooded cave

    Archaeologists exploring the world’s biggest flooded cave in Mexico have discovered ancient human remains at least 9,000 years old and the bones of animals that roamed the earth during the last Ice Age. A group of divers recently connected two underwater caverns in eastern Mexico to reveal what is believed to be the...
  • SpaceX ‘Starman’ at wheel of sports car flying on new rocket

    CAPE CANAVERAL, Fla. — A SpaceX “Starman” is aboard the company’s new rocket that’s set to make its launch debut from Florida SpaceX chief executive Elon Musk revealed pictures of the surprise dummy passenger Monday. Test flights usually carry steel or concrete for cargo, or mundane experiments — nothing...
  • HOW DARK MATTER PHYSICISTS SCORE DEALS ON LIQUID XENON

    IF YOU WANT to build and run a $70 million dark matter detector, you’re going to have a hefty shopping list. You’ll need to buy hundreds of photomultiplier tubes, set up elaborate electronics, and pay graduate students, for starters. And 20 percent of your cash is going to go to...
  • “Quantum Radio” May Aid Communications and Mapping Indoors, Underground and Underwater

    Researchers at the National Institute of Standards and Technology (NIST) have demonstrated that quantum physics might enable communications and mapping in locations where GPS and ordinary cellphones and radios don’t work reliably or even at all, such as indoors, in urban canyons, underwater and underground. The technology may help...
  • Organic molecules can form in space-like environments; reveals life could have originated in space

    Giving some credence to the view that life could well have originated in space, a new study has shown that a number of small organic molecules can form in a cold, space-like environment full of radiation. Investigators at the University of Sherbrooke in Canada created simulated space environments in which thin...
  • Physicists Prove Existence of New Form of Matter: Excitonium

    Excitonium is a condensate — it exhibits macroscopic quantum phenomena, like a superconductor, or superfluid, or insulating electronic crystal. It’s made up of excitons, particles that are formed in a very strange quantum mechanical pairing, namely that of an escaped electron and the hole it left behind. It defies reason,...
  • WOULD YOU PUT THE GENETICALLY MODIFIED ARCTIC APPLE IN YOUR PIE?

    ON THE LAST Monday of September, 32 field workers stepped onto a 15-acre experimental plot in an undisclosed part of Washington and made apple harvest history. The fruits they plucked from each tree were only a few months old. But they were two decades and millions of dollars in the...
  • HOW TO BUILD A ROBOT THAT WON’T TAKE OVER THE WORLD

    SAAC ASIMOV’S FAMOUS Three Laws of Robotics—constraints on the behavior of androids and automatons meant to ensure the safety of humans—were also famously incomplete. The laws, which first appeared in his 1942 short story “Runaround” and again in classic works like I, Robot, sound airtight at first: A robot may not...
  • Scientists Unleash CRISPR on RNA

    The CRISPR-Cas9 gene-editing system allows scientists to permanently alter the human genome faster and more precisely than ever before (see Sep 2014 news; May 2016 news). What if scientists wanted to make a temporary change, by targeting RNA instead? In the October 25 Science, researchers led by Feng Zhang of the Broad Institute of...
