How Large Can a Locust Swarm Get?

Here’s an interesting entry from The Writer’s Almanac of July 20, 2015 — “It was on this day 140 years ago, in 1875, that the largest recorded swarm of locusts in American history descended upon the Great Plains.

“The Secret History of Wonder Woman”

Did you know Margaret Sanger was an inspiration for Wonder Woman? I’ve just finished reading The Secret History of Wonder Woman by Jill Lepore, and it really was a complicated tale bound in secrecy. “The story of Wonder Woman’s origins wasn’t a neglected history, waiting to be written.  It was a family secret, locked in a

How Koalas Keep Cool

I just got back from a week in sunny Southern California (although it did rain for a day).  I was catching up reading my National Geographic magazines (they’re a good size for airplane trips) and I ran across this in the July 2015 issue — A 2014 study led by University of Melbourne ecologists showed

How Much Do You Know About Money?

I was out shopping Saturday night and I heard a cashier marvel about receiving a $100 bill.  Is that the largest bill in circulation? That piqued my curiosity, and I got on my smart phone.  According to the official website of the U.S. Department of the Treasury (http://www.treasury.gov/resource-center/faqs/Currency/Pages/denominations.aspx),  the denominations of currency now in production are
