It wasn’t for nothing that I asked these questions yesterday (and some of the responses were very helpful). Over at the Science Progress blog, I’ve now done a full piece about what happened in science in 2009, which includes observations like these:

It was a year of complete U-turns in science policy. President Barack Obama reversed George W. Bush’s dramatic restrictions on embryonic stem cell research, and the first 13 new stem cell lines were approved for federally funded research since 2001. Meanwhile, the Obama Environmental Protection Agency moved to regulate carbon dioxide emissions, finding that they do indeed endanger the public.

It was also the year of the first-ever passage, by a 219-212 margin in the U.S. House of Representatives, of a cap-and-trade bill that would cut domestic greenhouse gas emissions—but not the year for any parallel action in the U.S. Senate.

It was the year that everyone seemed to own an iPhone and use the word “app” in regular conversation. It was the year Twitter went from being a mere annoyance to the epitome of web-based communication.

It was a year that saw the very first Nobel laureate scientist assume a cabinet position, in the figure of U.S. Secretary of Energy Stephen Chu.

It was the year of….many, many, many other things, some funny, some outrageous, some profound. Read here for the whole list, and leave comments about anything you think may have been left out!
