As is traditional at the end of one year and the beginning of a new one, top 10 lists have come out. Both the online Wired Magazine and Science Magazine have come out with their own top 10 scientific discoveries. These are compared below side-by-side with links to additional information.
The two lists are different for most of the articles and the priority of the discoveries, reflecting different editorial perspectives I presume. Some of Wired choices are based on Science Magazine articles. You can get a good deal of information by merely signing up for free membership.
