March 5, 2013. Huge, aggressive mosquito may be abundant in Florida this summer, expert warns. March 5, 2013 by Tom Nordlie. If mosquitoes were motorcycles, the species known as Psorophora ciliata would be a Harley-Davidson big, bold, American-made and likely to be abundant in Florida this summer. I wouldn't be surprised, given the numbers we saw last year," said Kaufman, an associate professor with UF's Institute of Food and Agricultural Sciences. When we hit the rainy cycle we may see that again.".

January 1, 2015. Defying textbook science, study finds new role for proteins. January 1, 2015. Open any introductory biology textbook and one of the first things you'll learn is that our DNA spells out the instructions for making proteins, tiny machines that do much of the work in our body's cells. Results from a study published on Jan. 2 in Science. This surprising discovery reflects how incomplete our understanding of biology is," says first author Peter Shen, Ph.D., a postdoctoral fellow in bi...In an...
