A team led by James Marden at Penn State University discovered that descendants of "exploratory" butterflies that colonize new habitats differ genetically from their more cautious cousins. The research has revealed some of the genetic bases for traits that provide an advantage to butterflies that found new populations in previously unoccupied habitat patches. The results have potentially broad importance in understanding natural selection.Full Story

The U.S. National Science Foundation propels the nation forward by advancing fundamental research in all fields of science and engineering. NSF supports research and people by providing facilities, instruments and funding to support their ingenuity and sustain the U.S. as a global leader in research and innovation. With a fiscal year 2020 budget of $8.3 billion, NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and institutions. Each year, NSF receives more than 40,000 competitive proposals and makes about 11,000 new awards. Those awards include support for cooperative research with industry, Arctic and Antarctic research and operations, and U.S. participation in international scientific efforts.
