So here’s what went down since you logged off.

2,100 years ago, the ancient Greeks used an astronomical calculator to set the date of the Olympic Games.

Well, they were looking for human remains…Puerto Rican police found bones and possible artifacts from a colonial-era ship.

George Jetson, here we come – NASA is offering $300,000 to the first person who develops a Personal Air Vehicle. And – it’s got to be green.

The Chronicle has a new evolution blog – Evo.Sphere.

It has absolutely nothing to do with science (well, he did teach computer tech) but if you haven’t seen Randy Pauch’s The Last Lecture – you really should.

***UPDATE: Science won’t be sleeping next week, but I will be. Vacation! Have no fear, though – we’ve got lots of other very cool posts planned for all of next week, so please check back – and as always, leave us a comment to let us know what you think. SDS returns Aug. 11.
