    Doctors repair skin of boy dying from ‘butterfly’ disease

    Researchers fixed a genetic defect, then replaced about 80 percent of a child’s skin. This essentially cured the boy’s life-threatening disease.

    Small genetic accident made Zika more dangerous

    A new study finds that a tiny mutation made the Zika virus more dangerous, by helping it kill cells in the fetal brain.

    Explainer: Why scientists sometimes ‘knock out’ genes

    How do we learn what a particular molecule does in the body? To find out, scientists often 'knock out' the gene that makes it. Here’s how.

    One day, your sunscreen may be made from DNA

    A new approach to sunscreen could use a thin layer of DNA to protect skin cells — and hopefully prevent cancer.

    Genes may predict how well the flu vaccine will work in young people

    The activity of nine genes predicted how well people 35 and under would respond to the flu vaccine.

    Molecular scissors fix disease-causing flaw in human embryos

    Researchers moved closer to being able to fix gene-edited embryos in people. They removed a flawed gene that causes heart failure

    Scientists hide a real movie within a germ’s DNA

    A gene-editing technology called CRISPR helped scientists encode a short movie in the DNA of E. coli bacteria.
