National Geographic: UC professor discusses ancient spiders
UC biology professor Nathan Morehouse says fossils suggest ancient spiders were night predators
A University of Cincinnati biology professor spoke to National Geographic about the recent discovery of spider fossils in South Korea.
The discovery by the Korea Polar Research Institute suggests ancient spiders had reflective eyes like many of today’s spiders.
If you shine a flashlight in your grassy back yard, you’re likely to see tiny eyes shining back at you. These are the glowing eyes of wolf spiders, which have an iridescent lens called a tapetum that reflects light.
According to National Geographic, paleontologists discovered nearly a dozen inch-long fossils of ancient spiders dating back more than 106 million years during the Cretaceous Period. These spiders, too, have reflective lenses that capture more light for animals that are active at night. Their findings were published in the Journal of Systematic Paleontology.
“These fossils are extraordinary,” UC biology professor Nathan Morehouse told National Geographic.
“It’s always a thrill when something of the visual system is preserved,” he said. “More exciting to me and other vision scientists is the glimpse that the tapetum offers into the lifestyle of these ancient animals. They were likely nocturnal hunters!”
Morehouse has been studying the vision and behavior of spiders, particularly jumping spiders, in UC’s McMicken College of Arts and Sciences. He is using a National Science Foundation grant to study spider vision around the world.

Pi Day: Where math meets dessert

Pi Day is celebrated on March 14 around the world, as March 14 represents its first three numbers, 3.14. It’s a yearly celebration for math lovers to see who can recite the most digits, talk about its history and have an excuse to eat many, many pies! First, the math: PI is the Greek letter “π” and it is the symbol used in mathematics to represent a constant, as it is the ratio of the circumference of a circle to its diameter. It has been calculated to over 50 trillion digits beyond its decimal point and will continue to repeat, as it is an irrational and transcendent number.
