    Future quantum computing could exploit old technology

    Silicon transistors have been converted into the basic components of a quantum computer.

    Using modified versions of transistors used in smartphones, tablets and desktop computers, Australian engineers have built the first quantum logic gate in silicon for performing quantum computations. The gate, described October 5 in Nature...

    Chemistry Nobel granted for deciphering DNA repair

    Identifying the molecular repair kits that cells use to fix damaged DNA has won three scientists the 2015 Nobel Prize in chemistry. Tomas Lindahl of the Francis Crick Institute in England, Paul Modrich, a Howard Hughes Medical Institute investigator at Duke University School of Medicine, and Aziz Sancar of the University of North Carolina School of Medicine uncovered three tools for correcting...

    Special Report: Gravity’s Century

    In 1915, the universe was small and static. Space was smooth. Gravity pulled things to the ground. At least that’s the way it was in the minds of all but one exceptional physicist — Albert Einstein.

    After years of pondering the interplay of space, time, matter and gravity, Einstein produced, in a single month, an utter transformation of science’s conception of the cosmos: the general...

    Entanglement: Gravity's long-distance connection

    View the video

    When Albert Einstein scoffed at a “spooky” long-distance connection between particles, he wasn’t thinking about his general theory of relativity.

    Einstein’s century-old theory describes how gravity emerges when massive objects warp the fabric of space and time. Quantum entanglement, the spooky source of Einstein’s dismay, typically concerns tiny...

    Chemistry Nobel honors studies of DNA repair mechanisms

    Studies of DNA’s repair mechanisms have won Tomas Lindahl, Paul Modrich and Aziz Sancar the 2015 Nobel Prize in chemistry.

    DNA encodes the instructions for building and conducting life. But it’s a fragile molecule that can be altered or damaged by sunlight, toxic chemicals, radiation or even normal chemical reactions inside the cell.

    Lindahl, of the Francis Crick Institute in...

    Using general relativity to magnify the cosmos

    One of the most powerful known magnifying lenses isn’t found on Earth. The lens is built from stars, gas and dark matter and lies about 4 billion light-years away. As astronomers peer through it, they are finding the seeds of galaxies that were scattered around the universe more than 13 billion years ago.

    The lens is known as Abell 2744, a cosmic pileup where four groups of galaxies are...

    Centennial books illuminate Einstein’s greatest triumph

    You don’t need an anniversary as an excuse to write a book about Albert Einstein. But the centennial of his general theory of relativity has nonetheless provided an occasion for several new entries in the Einstein library. And even though general relativity — Einstein’s theory of gravity — has been thoroughly explored many times, some 2015 publications do offer new twists and insights.

    Einstein's genius changed science's perception of gravity

    Albert Einstein opened humankind’s eyes to the universe.

    Before Einstein, space seemed featureless and changeless, as Isaac Newton had defined it two centuries earlier. And time, Newton declared, flowed at its own pace, oblivious to the clocks that measured it. But Einstein looked at space and time and saw a single dynamic stage — spacetime — on which matter and energy strutted,...

    Fizzy bubbles carry drugs deep into wounds

    View the video

    Alka-Seltzer’s frothy fizz may hold the secret to stopping blood loss. 

    Jets of rushing bubbles can carry blood-clotting drugs deep into a wound and seal it shut, scientists report October 2 in Science Advances.

    The work is the first to show bubble-powered devices...

    Elusive acid finally created

    After more than a century of searching, chemists have finally nabbed a legendary acid.

    The acid called cyanoform or tricyanomethane appears widely in textbooks as one of the strongest carbon-based acids known. Yet despite attempts to make the acid dating back to 1896, cyanoform has evaded chemists until now. Researchers report September 18 in Angewandte Chemie International Edition...
