Penn State biologists explore the secrets of the warbler genome

Looking through binoculars at the trees in their backyards during the pandemic, many brand-new birders may have been surprised by the diversity of visitors stopping by — finches, jays and warblers in an astounding array of yellows, blues and reds.

Latest NSF rankings show breadth and depth of Penn State research

Penn State’s research enterprise ranks 22nd in the country in total research expenditures, according to the latest National Science Foundation rankings of Higher Education Research and Development (HERD) research expenditures, released in January 2022.

A selfie taken by NASA's Curiosity Mars rover on Sol 2291 at the "Rock Hall" drill site, located on Vera Rubin Ridge. Reduced carbon released from powder from this drill hole was strongly depleted in carbon 13, the surprising carbon isotopic signature reported by the team. The selfie is composed of 57 individual images taken by the rover's Mars Hand Lens Imager (MAHLI), a camera on the end of the rover's robotic arm.   Credit: NASA/Caltech-JPL/MSSS.

Newly discovered carbon may yield clues to ancient Mars

NASA's Curiosity rover landed on Mars on Aug. 6, 2012, and since then has roamed Gale Crater taking samples and sending the results back home for researchers to interpret. Analysis of carbon isotopes in sediment samples taken from half a dozen exposed locations, including an exposed cliff, leave researchers with three plausible explanations for the carbon's origin — cosmic dust, ultraviolet degradation of carbon dioxide, or ultraviolet degradation of biologically produced methane.

Entomologists to study how climate change may influence pollinator stressors

A Penn State-led team of researchers will use a newly awarded $682,000 grant from the U.S. Department of Agriculture's National Institute of Food and Agriculture to examine how climate change may influence and interact with various stressors that affect the health of pollinators.
