    Weight and sun exposure linked to onset of multiple sclerosis

    People with multiple sclerosis who got less sun exposure and had higher body mass as young adults developed the disease sooner than those who spent more time in the sun and were a normal weight, a new study finds.

    In a study of over 1,100 Danish people with MS — a nervous system condition that causes muscle...

    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...

    How the giraffe got its long neck

    The neck of a giraffe isn’t all that different from any other mammal’s. There are seven neck vertebrae, like those of humans, but they are much bigger. (This is a different strategy than other long-necked creatures in history. Marine reptiles called plesiosaurs, for instance, had 38 to 42 vertebrae to lengthen their...

    Oldest pregnant horselike fossil found

    A confluence of unlikely events led to the exquisite preservation of the oldest fossil of a primitive pregnant horse ever discovered.

    Some 48 million years ago, an equoid mare (Eurohippus messelensis) and her almost fully gestated fetus fell into an ancient lake in the area of Grube Messel near Frankfurt, Germany. The lake had just the right mix of bacteria to preserve even soft...

    General relativity centennial celebrates Einstein’s genius

    eva headshotEinstein is shorthand for genius, and describing everything Albert Einstein did to inspire that synonym would take a book, or multiple books (see...

    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...

    No eyes, no problem for color-sensing coral larvae

    Staghorn coral larvae don’t have eyes. Yet shifting the color of underwater light can reverse their usual preferences for spots to settle.

    Horizontal surfaces bathed in blue-green light attract more larvae of Acropora millepora coral than normal, says behavioral ecologist Marie Strader of the University of Texas at Austin. And vertical surfaces lit through red filters...
