I hope you had a happy Fourth of July (or as I like to say, Disloyalty to Royalty Day). Did you watch any fireworks displays? I’ve been hearing news reports about communities having to cancel their programs due to a shortage of trained explosives technicians. But assuming you were able to see some fireworks somewhere,
Harvester ants are very industrious. They build mounds that last for decades, protecting them with a half-inch-thick layer of small rocks about the size of beads, then clear the surrounding area of vegetation by as much as 30 feet. But in gathering up all those rocks, they also collect tiny fossils and archaeological artifacts. Don’t
On the night of Aug. 15, 1977, during a SETI search, the Ohio State University’s Big Ear telescope picked up an unknown signal that was incredibly strong but very brief, lasting a mere 1 minute and 12 seconds. It was so unexpected that its discoverer, astronomer Jerry Ehman, wrote “Wow” on the printout, thus giving this
Homo Sapiens have always had the ability to walk upright. The key to this biological ability is our foot’s remarkable design. For example, short toes give us the ability to run long distances. Surprisingly, another critical design feature appears to be the transverse tarsal arch — the horizontal curve that runs across the top of
I have read that the world’s largest animal is a blue whale, and the largest living organism is a fungus (https://www.scientificamerican.com/article/strange-but-true-largest-organism-is-fungus/). But what is the largest plant? Whatever it was before, we have a new winner. Scientists have determined a 110-mile-long meadow of seagrass in Shark Bay, Western Australia is actually a single plant. It has
Granted that the Star Wars universe is in a galaxy far, far away, just how realistic are the technological advances from that world? According to the article “May the 4th be with you: 7 Wild ‘Star Wars’ Technologies Scientists Are Building Right Now” by Brandon Specktor, they may be more realistic than you think. The
Zombies aren’t the only ones looking for brains. Used brains of all kinds are needed for medical research to advance the discovery of better treatments and cures for brain diseases, disorders, and injuries. If this interests you, check out the Brain Donor Project at https://braindonorproject.org/. This topic is especially timely because there is a campaign
Clouds can form some imaginative formations, but a new one on me is a cloud street. A cloud street, or more technically a horizontal convective roll, is actually a long row of cumulus clouds that is aligned parallel to the direction of the wind. They usually form straight rows, but when the wind hits an obstacle,
If you are squeamish about spiders, you may not want to know there are approximately 50,000 different species. And you certainly don’t want to know that of these, at least 20 species live in colonies. Are you still with me? One of these species, Anelosimus eximius, lives in very large colonies, as many as 1,000 individuals. In
The closest we’ve ever come to a real tooth fairy is probably Erin Dunn, a psychiatric epidemiologist at Massachusetts General Hospital. Dunn calls herself “the science tooth fairy” to encourage kids to donate their baby teeth for science. She gives the teeth to Felicitas Bidlack, a specialist in tooth development at the Forsyth Institute, an oral
