Year in Science: Genetic breakthroughs make dreams (and nightmares) come true

In science, it was the best of times, and the worst of times.
2018 was a year when researchers focused in on ways to head off disease by reprogramming a patient’s own cells, but also crossed what many thought were ethical red lines in genetic experimentation. It was the first year in which women won a share of the Nobel Prize for physics as well as for chemistry, but also a year when the #MeToo issue came to the fore in the science community.
And it was the year that marked the passing of British physicist Stephen Hawking, who was arguably the world’s best-known living scientist.
