October 9, 2013 Scientists who do research in Antarctica have just learned that the shutdown will effectively cancel all of their planned fieldwork on the icy continent this year. All research activities not essential to human safety and the preservation of property will be stopped.
October 7, 2013 Scientists who study the remote, rugged continent at the bottom of the world are on edge as funding for research there remains in jeopardy. It hasn't been decided yet if Antarctic operations for the research season will be allowed to continue.
