Here's a question about the fine line between a prudent response and worrisome overkill: Is the sight of a U.S. Coast Guard helicopter hovering over a cruise ship to pick up a blood sample (which is to be tested for Ebola) a sight that should inspire feelings of reassurance, or a nagging sense that something is not quite right?

Mars is about to get a visitor that comes around only once in a million years or so.

The arrival of a "mountain-sized" comet, Siding Spring (C/2013 A1), is made all the more extraordinary by the fact that humans — who were busy refining their stone-tool-making skills the last time such an event might have occurred — now have spacecraft from multiple countries at the Red Planet to see it happen.
