    Mathematicians report possible progress on proving the Riemann hypothesis

    Researchers have made what might be new headway toward a proof of the Riemann hypothesis, one of the most impenetrable problems in mathematics. The hypothesis, proposed 160 years ago, could help unravel the mysteries of prime numbers.

    Mathematicians made the advance by tackling a related question about a group of expressions known as Jensen polynomials, they report May 21 in Proceedings...

    The kilogram just got a revamp. A unit of time might be next

    The new kilogram has finally arrived.

    Updates to scientists’ system of measurement went into force May 20, redefining the kilogram and several other units in the metric system. The revamp does away with some outdated standards — most notably, a metal cylinder kept in a vault near Paris that has defined the kilogram for 130 years (SN: 12/8/18, p. 7).

    Tinkering with units allows...

    A mathematician traces his journey from poverty to prominence

    The Shape of a LifeShing-Tung Yau and Steve NadisYale Univ., $28

    One of the first remarkable things that mathematician Shing-Tung Yau reveals in his memoir, The Shape of a Life, is that his name was not originally Yau. His family fled China to British-ruled Hong Kong in 1949 when he was an infant, and the name Yau came from a mistranslation on a registration form when he entered...

    Mathematicians may have found the fastest way to multiply huge numbers

    Multiplying 2 x 2 is easy. But multiplying two numbers with more than a billion digits each — that takes some serious computation.

    The multiplication technique taught in grade school may be simple, but for really big numbers, it’s too slow to be useful. Now, two mathematicians say that they’ve found the fastest way yet to multiply extremely large figures.

    The duo claim to have...

    Photons reveal a weird effect called the quantum pigeonhole paradox

    Quantum pigeons don’t like to share.

    In keeping with a mathematical concept known as the pigeonhole principle, roosting pigeons have to cram together if there are more pigeons than spots available, with some birds sharing holes. But photons, or quantum particles of light, can violate that rule, according to an experiment reported in the Jan. 29 Proceedings of the National Academy of...

    Readers have questions about Parkinson’s disease, moth wings and more

    Gut connection

    Abnormal proteins tied to Parkinson’s disease may form in the gut before traveling through the body’s nervous system to the brain, Laura Beil reported in “A gut-brain link for Parkinson’s gets a closer look” (SN: 12/8/18, p. 22).

    The vagus nerve offers a connection between nerves in the gut and those in the brain. Beil reported on one study that showed that people who...

    It’s official: We’re redefining the kilogram

    Out with the old — kilogram, that is.

    Scientists will soon ditch a specialized hunk of metal that defines the mass of a kilogram. Oddly enough, every measurement of mass made anywhere on Earth is tied back to this one cylindrical object. Known as “Le Grand K,” the cylinder, cast in 1879, is kept carefully sequestered in a secure, controlled environment outside Paris.
