The (Revised) Calendar of Science Holidays

(Note from Julie: Well, Blogger and I had a falling out over my previous Calendar of Science Holidays. So, I thought I'd recreate the post here. My apologies to those kind folks who commented on the previous version and sent me new holidays. Please add your comments or any link corrections here. Thanks!)


Each year holds a wealth of weird, wacky, and interesting -- yet under-celebrated -- days for science, like World Meteorological Day and World Water Day. I decided to put together a calendar of annual science holidays and special events that celebrate science so that we could enjoy them together.

National events listed here refer to the United States, unless otherwise noted. Of course, if you live outside of the US, you are more than welcome to celebrate with us! (And I'll admit, some of these holidays are a little less "official" than others.) I expect to update this post in the future, so feel free to send me your special day and I'll add it to the list. Thanks!

The Tangled Bank: Love, Wonder, & Evolution

I received a happy email today from Chris Lynch, the editor at Tangled Bank Press, which largely said this:

The Tangled Bank: Love, Wonder, & Evolution has launched!

The anthology, which marks the 150th anniversary of Charles Darwin's Origin of Species, features over 100,000 words of speculative fiction, poetry, artwork, and essays about evolution. An international line-up of nearly 50 contributors includes Sean Williams, Brian Stableford, Patricia Russo, and Carlos Hernandez. (And me!)

The Tangled Bank is now available for download as a PDF (cost is US$4.99). Check out "Darwin's Daughter" by Christopher Green, a free short story from the anthology.

For more information, please visit the Tangled Bank Press, drop by Facebook, or follow us on Twitter.

Happy Darwin Day, everyone!

They're B-A-A-C-K!

Well, so much for moving. I had naively hoped that when we moved to our new townhouse, we'd be free of ants. No such luck. I've heard from friends that, in this area of the U.S., ants are very persistent.

But ... I discovered something interesting about the ants at our new home. They seem to be smarter than the ants at our old place. How can I tell? Two things:

At our old house, you could observe a line of ants without disturbing them. They didn't get upset and scurry until I began to vacuum or started using my mint oil spray. Here, the minute I walk in the room, they run for cover (making it very hard to tell how they are getting into the house!)

And here, the ants are sneaky. I found them coming into my kitchen through a power outlet (!) and then they were crawling along a black electrical wire (blending in) to enter house (and the fruit bowl - ick). Here, ants tend to follow hidden paths -- underneath the sink or along the underside of the countertops and dishwasher -- making it hard to track them. At our old place, the ants not only entered the house in the open, if I fought back with spray, they'd re-enter days later at the same place.

So ... are my new ants smarter? I've never thought about ants having varying levels of intelligence before. I doubt that individual ants would show much difference in intelligence (I wonder how you could test that?). But this new colony definitely seems to have evolved a more sophisticated style of suburban survival. Very interesting ...
