You’ve heard of “never smile at a crocodile”? You may not want to cry around one either. A new study of Nile crocodiles has found they respond to the sound of human babies crying, as well as infant chimpanzees and bonobos. Researchers played cries from human, chimpanzee and bonobo infants to a group of Nile
Our bodies are pretty complicated mechanisms, and they’re complex in ways we don’t fully understand. For example, why do some people have naturally curly hair? According to new research, there may have been a good evolutionary reason. A recently published research article by Tina Lasisi and her colleagues at Pennsylvania State University examined how hair regulates scalp
Beavers are nature’s master builders. Their dams can change a landscape, creating wetlands and enriching the habitats of other species. They’re also cute, with fur that’s been highly prized in other eras. But frequently they get in our way. Our developments don’t utilize dams made of trees and saplings. We like our land dry and
It’s probably pink. The success of the new movie Barbie has created a wave interest in the color most associated with girls (and yes, Barbie Pink is a Pantone color), but like so much in life, its complicated. According to a 2018 research article, bright-pink pigments have been found in 1.1 billion-year-old rocks, the result of
I remember when the height of horticultural wisdom was to talk to your houseplants to supposedly help them thrive. I used to joke with friends about taking this advice to heart. Then when my plants started answering me, I knew I needed to take a break and get out of the house. But according to
During one of my substitute-teaching assignments, at the last minute I was asked to cover a class in the vocational area of the high school. All I was given was a room number, so I was surprised to find a classroom with a hospital bed, examination table, and other medical equipment. It was a pre-nursing
The Möhne dam the day following the attacks. Wikipedia Sometimes the wildest ideas turn out not to be so wild after all. Like designing an aerial bomb that skips across the water like a flat stone and blows up dams. That would be World War II’s Operation Chastise. On the night of May 16-17 1943,
How big does a forest have to be to make a difference in people’s lives? Not very big. Greenery condensed to the size of a tennis court can have a huge effect. This small-is-good idea germinated in the 1970s with Japanese botanist Akira Miyawaki, who pioneered a way to plant young indigenous species close together to
What do you consider space food? In the Apollo era, astronauts ate freeze-dried, cube-shaped delicacies such as shrimp cocktail and date fruitcake, which proved entirely adequate. Apollo 8 crew member Jim Lovell was quoted as saying “Happiness is bacon squares for breakfast” while midway to the moon in 1968. Visitors to the International Space Station typically
No matter what you think about our newest federal holiday, to me it’s more evidence that race is the thread that connects all of our history. For example, I’ve just found a National Geographic article entitled “How Two Centuries of Slave Revolts Shaped American History” by Erin Blakemore (https://www.nationalgeographic.com/history/article/two-centuries-slave-rebellions-shaped-american-history?). Most people are familiar with Nat
