    That familiar feeling comes from deep in the brain

    It’s happened to all of us at one time or another: You’re walking through a crowd, and suddenly a face seems incredibly familiar — so much so that you do a double-take. Who is that? How do you know them? You have no idea, but something about their face nags at you. You know you’ve seen it before.

    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...
