How did humans get to be so much fatter than our closest primate relatives, despite sharing 99% of the same DNA? A new study suggests that part of the answer may have to do with an ancient molecular shift in how DNA is packaged inside fat cells, which curbed our body's ability to turn 'bad' white fat into 'good' brown fat.

Six months ago, a Chinese scientist announced that he had edited the genomes of two babies born last year. The germline edits with CRISPR-Cas9 supposedly changed the CCR5 gene to prevent HIV from invading immune cells.
