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
World travel can be life-changing. I’ve visited Hiroshima, Japan; China’s Great Wall; and Kenya’s savanna with its abundant wildlife. All have made a huge impression om me in their own special way.

Putting fish in small bowls, especially without filtration and oxygenation, is now considered animal abuse. “People buy a goldfish for their kids on impulse, but if they knew what
Pets give us much comfort and companionship. And there is a segment of society to whom pets are doubly important — the homeless. Reportedly, 10 to 25 percent of homeless people have pets. Yet they require care, too. But it’s tough to look after an animal if you might not know where your next meal
This is something you probably haven’t thought of, but I think it’s interesting. Suppose you lived on another planet in the solar system. It starts raining and you’re caught without your umbrella. How big will the raindrops be? Two researchers at Harvard University published a paper on the physics of raindrops on March 15, 2021
I’m sure you’ve heard of some people being described as “swimming like a fish.” It might surprise you to learn that some fish don’t swim well at all. Why would some fish be poor swimmers? The simple answer is they don’t need to swim well. For example, if the pufferfish (also called blowfish) is chased, it
Of all the messages about climate change, perhaps the most original is the dinosaur who addresses the United Nations. Yes, in a recent YouTube video, a dinosaur walks into the UN’s General Assembly and delivers an impassioned speech to stunned delegates. The bottom line: Don’t choose extinction. “I know a thing or two about extinction,
