A tumultuous US presidential campaign ended in a surprise victory for Republican businessman Donald Trump in November. Researchers struggled ...

Fabián Díaz achieved a milestone last year when he derived the first human embryonic stem-cell line from cells of Mexican origin. Biologists across Mexico now use the stem cells, which Díaz — a researcher at the National Institute of Perinatology in Mexico City — created using embryos discarded by a fertility clinic...
