Did You Enjoy Your Shorter Days?

Something you may have missed (and I’m a bit late in mentioning) is that timewise three recent days were shorter. Wait, what? Yes, it seems July 9, July 22 and August 5 were unusually short. We like to think our days are 24 hours, but the real world is never that simple. Earth’s rotation is actually

How We Got Potatoes

The ability to analyze genomes has given us great insight into the evolution of many animal species, including us. But have you ever wondered how plants evolved? Recently, scientists have discovered how one of our favorite food plants came to be. By using advanced genomic tools that are now available, researchers have deduced that random

The Real Tooth Fairy

If you are looking for a feel-good story, The New York Times recently found one. It seems the tooth fairy is real. Her name is Dr. Purva Merchant and she’s a pediatric dentist in Seattle, Washington. Which brings up the question, how did she get the job? It started with her boyfriend-now-husband who in 2004

Is Anyone Worried About Doomsday?

When I was growing up in the 1950s and 1960s, nuclear war was considered a real possibility. Every home-improvement show I remember attending had at least one contractor selling fallout shelters. But with the end of the Cold War, we don’t have to worry about that any more, do we? Actually, there is one organization

Which Animals Can Do Math?

On a visit to SeaWorld (the one in Aurora, Ohio before it merged with Six Flags Ohio in 2000), I remember a concession which sold fish to feed dolphins. For a reasonable fee (I think $5), you purchased three small, sorry-looking fish in a cone-shaped paper cup at a stand next to a large pool

How to Flirt in the Victorian Age

Social mores sure do change. Introducing yourself to the opposite sex has always been challenging (at least for me), but we can take some solace in knowing that this has been a problem throughout history. This is especially true during times when many women needed a chaperone to be seen in public. So it’s interesting

Can I Get a Lift?

You may have heard about a mako shark swimming with an orange octopus hitching a ride on its head. This behavior did surprise a lot of people. But scientists have realized it’s not unusual in the animal kingdom. As described in “‘Sharktopus’ Wasn’t the First. These Animals Also Hitchhike on Other Animals” by Jason Bittel

Can a Bird Predict the Weather?

Or more accurately, the hurricane season? There is such a bird, the veery thrush, that every year migrates thousands of miles from the northern United States and southern Canada across the Gulf of Mexico and the Caribbean Sea to South America. But there are two complications — the veery thrush only weighs about 30 grams, and the

Beware of Orcas Bearing Gifts

I’ve always been interested in communicating with animals. My second novel, Canine Champions, is about a boy and a dog with a telepathic link. But that’s more science fiction than reality. What about the real world? What is the status of our attempts to communicate with animals? And increasingly, their attempts to communicate with us?
