Joro spiders are heading up the coast
UC biologist says these garden spiders want to stay in the garden
Everyday Health turned to a University of Cincinnati biologist to learn more about an invasive spider from Asia that is showing up in more American back yards.

Female spiders grow to more than 3 inches in length. They build equally enormous webs spanning more than 10 feet to catch flying insects, which makes it hard for them to go unnoticed in gardens and back yards. But they are harmless and don't bite people, said George Uetz, a professor emeritus in UC's College of Arts and Sciences.
“They are very sedentary in their webs,” he told Everyday Health.
Uetz spent his career studying the fascinating behavior of spiders and other animals in his biology lab. He was named a fellow this year of the American Association for the Advancement of Sciences.
If disturbed, the spider freezes in place for as long as an hour.
“Approach them from a distance, observe them, and you will see they are no threat, as they stay in their web,” Uetz said.

Researchers at the University of Cincinnati College of Medicine say an experimental gene therapy could eventually lead to a less invasive treatment for hydrocephalus, a condition in which excess fluid accumulates in the brain. The early-stage study, led by Agnes (Yu) Luo, PhD, professor and vice chair for research, was published in the journal Fluids and Barriers of the CNS. Yahoo! News recently featured it.
