Chemistry is a subject we don't usually delve to deeply into here at Engadget, but this year is a special year for the science, marking the International Year of Chemistry. This event, which was made official by the United Nations, seeks to bring worldwide attention to the achievements in the field of chemistry which have contributed the welfare of humankind. Sponsored by 23 nations and various organizations, including the American Chemical Society, it includes the very interesting 365: Chemistry for Life calendar, which marks nearly every day of the year with a significant development in chemistry, such as January 8th, which commemorates Aircraft De-icers, which we are very, very grateful for. Hit up the source links to check out the full calendar.
