Why is a koala bear a marsupial and not a bear? Because it doesn’t have the right koala-fications. Since this subject has come up, here are some facts about koalas. According to the San Diego Zoo, koalas are mammals, and they do resemble teddy bears with their round, fuzzy ears. But they are definitely marsupials,
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
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
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
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
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
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?
On my recent trip to Chile, our group got a chance to visit an astronomical observatory in the Atacama Desert. The sky is completely different in the Southern Hemisphere. The Big Dipper is upside down just above the horizon and (of course) Polaris can’t been seen. Other unusual features of the sky in that part
Never underestimate the adaptability of nature. I was reminded of this again by a Smithsonian Magazine article entitled “Five Shocking Animal Hybrids That Truly Exist in Nature, From Narlugas to Grolar Bears to Coywolves” by Carlyn Kranking (https://getpocket.com/explore/item/five-shocking-animal-hybrids-that-truly-exist-in-nature-from-narlugas-to-grolar-bears-to-coywolves?) Some of these are pretty predictable, like the liger, the result of a male lion and female tiger,
The rainbow-colored light is an artist’s concept of a galaxy without stars called J0613+52. The stars in this image are foreground stars, in our own Milky Way galaxy, from an actual starfield from the Palomar Sky Survey II. Illustration via NSF/ NRAO/ AUI/ P.Vosteen/ Green Bank Observatory. Just when scientists think they have seen it all,
