"on the order of 0.1 centimeter in length" You mean a millimeter? Even "a tenth of a centimeter" is better. They also could say "1800 miles per hour" in the title if they want people to be able to take it in quickly. (or 2900 kph) Maybe I'm just nitpicking, but it seems like they are trying to make it harder to take in.
