In 2018, we saw just how much power science has to make a real impact. 

Science News’ top stories of the year include a literal impact—the hidden contours of what appears to be a massive crater created when a meteorite slammed into Greenland long ago. That discovery ranks among the Top 10 partly because it’s just cool, but also because it raises the tantalizing prospect of solving a scientific mystery: Did the impact kick the planet into a roughly 1,000-year cold snap, called the Younger Dryas, almost 13,000 years ago?

2018 is also the year a Chinese researcher made the startling claim that he had created the first babies to be born with an edited gene.
