Cosmos Magazine: UC biologists on Galapagos finches and genetic diversity

Published research on genetic diversity getting international attention

UC graduate Heather Farrington and UC biologists Kenneth Petren and Lucinda Lawson found that genetic diversity was not a good predictor of whether populations of finches would survive.

Their work was recently featured in Cosmos Magazine

The study was published in the journal Conservation Genetics in August. A UC lab analysis of century-old museum specimens found that six of eight extinct populations had more genetic diversity than similar museum specimens from which descendants survive today. In most other species, low genetic diversity is a signal of a population in decline.

Pi Day: Where math meets dessert

March 12, 2026

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.

Engineers develop deft solution to orient robots in space

March 11, 2026

To keep a repair robot stable while fixing satellites in space, University of Cincinnati engineers took a page from experts in balance: bull riders. UC College of Engineering and Applied Science graduate student James Talavage and Professor Ou Ma looked at simple but effective ways for a robot to maintain orientation while working on a broken satellite in zero gravity.
