    Physicists double their teleportation power

    The bandwidth for quantum teleportation has doubled. A new technique transfers information about one particle so that another particle takes on two, rather than just one, of the original particle’s quantum properties.Chinese researchers accomplished the feat by nesting one quantum teleportation apparatus inside another. “It’s impressive,” says Wolfgang Tittel, a quantum physicist at the...

    The past according to Planck: Cosmologists got a lot right

    A new analysis of the universe’s first light has cosmologists simultaneously patting themselves on the back and scratching on their chalkboards. The results, obtained from the Planck satellite and posted online in February in a set of papers at, largely support the theoretical framework that cosmologists employ to describe the universe....

    Quantum guessing game uses the future to predict the past

    Predictions are much easier to make with the benefit of hindsight. Scientists successfully predicted an important quantum property midway through an experiment by analyzing measurements taken before and after. The research, scheduled to appear in the Feb. 13 Physical Review Letters, demonstrates that...

    Top 10 messages to send to E.T.

    SAN JOSE, Calif. — Let’s face it. Communicating with aliens isn’t working out any better than persuading creationists to accept evolution. Scientists with the SETI project have been listening for decades, but so far not a peep from E.T. Anyone longing for alien contact has to settle for watching sci-fi movies or Doctor Who.Consequently some of science’s alien hunters have proposed being...

    When entering a black hole, fasten your seat belt

    As if someone falling into a black hole wouldn’t face enough problems, new research reveals that the approach could get bumpy.Interacting ripples in spacetime can create turbulence in the vicinity of a black hole, scientists report in a paper to appear in an upcoming Physical Review Letters. Their study builds on previous research suggesting...

    Top 10 scientific mysteries for the 21st century

    The last few centuries have been pretty good for science. In the 17th century, Isaac Newton solved the ancient controversy over the nature of forces and motion with his three laws. In the 18th, Ben Franklin figured out a lot about electricity. In the 19th, Darwin explained the diversity of species, Maxwell revealed the physics of light, Mendeleyev defined the families of chemical elements. In the...

    Physicists debate whether quantum math is as real as atoms

    Second of two parts (read Part 1)Ernst Mach found atoms useful. But he didn’t believe they were real.The 19th century physicist-philosopher gained his greatest fame as an atom denier. He believed that reality consisted of sounds and colors and pressures...

    Bell’s math showed that quantum weirdness rang true

    First of two partsThere’s just enough time left in 2014 to sneak in one more scientific anniversary, and it just might be the most noteworthy of them all. Fifty years ago last month, John Stewart Bell transformed forever the human race’s grasp on the mystery of quantum physics. He proved a theorem...

    The medieval mentality of modern science

    Science coexists with society. Science shapes society, informs society, enables society to function in ways not possible without an in-depth knowledge of how the natural world works. But you can flip that coin and declare, equally accurately, that society shapes science. Science responds to societal needs, reflects societal values, conceives of nature within the framework of society’s prevailing...

    Two new particles found at Large Hadron Collider

    Guest post by Andrew GrantTwo new particles have been discovered at the world’s most powerful particle accelerator.Physicists with the Large Hadron Collider beauty experiment identified the particles, Xi_b'- and Xi_b*-, among the deluge of subatomic shrapnel produced when protons collide at the LHC near Geneva. Like protons, the particles each contain three fundamental components...
