A Glorious Year for Crop Circles and Crop Rectangles

Remember that billowing cloud of ash from Iceland that floated over Britain and other parts of northern Europe this past spring, shutting down airspace from London to Hamburg and filling airports with fuming travellers? It wasn’t all bad, I discovered yesterday. In fact if you were an archaeologist, particularly a British archaeologist, that plume of […]

Abstruse Goose: Make a Wish

I’m not exactly sure what this is a picture of — I’ve seen it somewhere, maybe a graphic picture of noise? some computer thing? — but given his title, Abstruse Goose clearly means us to think of it as stars. #1.  It looks real.  #2.  Abstruse Goose, if you’re out there, can you tell us […]

IVF: A Great Investment

Last summer, I wrote an article for the magazine New Scientist about a bold new initiative to provide low-cost in vitro fertilization—for as little as $300 per cycle—to poor women in developing countries. The article, entitled Cheap IVF offers hope to childless millions, described initiatives by the Swiss-based Low Cost IVF Foundation and the European […]

Ann has just published a very cool new book on a group of astronomers who created this beautiful map of the universe, the Sloan Digital Sky Survey. Her book is called A Grand and Bold Thing, and […]

Perseids against the Milky Way, Sigh

The Perseids are reliable, regular shooting stars, a meteor shower that shows up nights in late July every year.  I didn’t see the Perseids this year myself because Baltimore’s skies are a rich carnelian haze that hold nothing much and certainly not meteorites.  And Heather didn’t see them because, she thinks, of light pollution.  To […]

Nothing New Under the Sun

I looked up my parents’ house in London on Google Earth, and was excited to see not just the lush greenery of their garden, but smack in the middle of it, their rotary clothes line. This may not seem so thrilling to the average reader, but outdoor clothes lines are cool these days, and my […]
