- ScienceCast: Origins of the Endangered Przewalski's Horse
- An endangered species of horse -- known as Przewalski's horse -- is much more distantly related to the domestic horse than researchers had previously hypothesized, reports a team of investigators led by Kateryna Makova, a Penn State University associate professor of biology. (7 November 2011)
- Penn State Science is Among the Best Programs in the United States, New National Research Council Study Shows
- 09 November 2011 — Research and education programs in the basic sciences at Penn State are among the top programs in the United States, according to a comprehensive National Research Council study, updated in the spring of 2011, titled "A Data-Based Assessment of Research-Doctorate Programs in the United States." The study uses a broad range of measurements to rank the performance of over 5,000 graduate programs in 62 fields at 212 U.S. universities, including all the major research universities.
- ScienceCast: Life History, Mutation Rates, and Male Mutation Bias
- For the first time, scientists have used large-scale DNA sequencing data to investigate a long-standing evolutionary assumption: DNA mutation rates are influenced by a set of species-specific life-history traits. The team of researchers led by Kateryna Makova, a Penn State University associate professor of biology, used whole-genome sequence data to test life-history hypotheses for 32 mammalian species, including humans.

- ScienceCast: Zombie Ants
- New research by David Hughes at Penn State has revealed how infection by a parasitic fungus dramatically changes the behavior of tropical carpenter ants, causing them to become zombie-like and to die at a spot that has optimal reproductive conditions for the fungus. (29 July 2011)
- ScienceCast: IceCube Project at the South Pole
- IceCube, the world's largest observatory ever built to detect the elusive sub-atomic particles called neutrinos, has been completed in the crystal clear ice at the South Pole. (3 June 2011)
- ScienceCast: Flowering Plants and Ancient Gene Duplications
- The evolution and diversification of the more than 300,000 living species of flowering plants may have been "jump started" much earlier than previously calculated. According to Claude dePamphilis, a professor of biology at Penn State University and the lead author of the study, two major upheavals in the plant genome occurred hundreds of millions of years ago -- nearly 200 million years earlier than the events that other research groups had described.

- ScienceCast: Flowering Plants Have Evolved Multiple Genes to Prevent Inbreeding
- Teh-hui Kao, a Penn State professor of biochemistry and molecular biology, has discovered several genes that act to prevent inbreeding in flowering plants. (6 January 2011)
- ScienceCast: How Easily Do Diseases Spread Through a Closed Group of People?
- Penn State biologist Marcel Salathé has studied how colds and the flu are transmitted from person to person. (13 December 2010)
- ScienceCast: Studying the Songbird's Brain
- Dezhe Jin of Penn State's Department of Physics has studied how the finch's brain controls timing during singing. (13 December 2010)
- ScienceCast: Claude dePamhilis and Research on Amborella
- Penn State biologist Claude dePamphilis leads an ambitious project to sequence the genome of Earth's most ancient living flowering plant, Amborella. (25 October 2010)
- ScienceCast: New Method for Tracking Seed Dispersal and Establishment
- Penn State biologist Tomás Carlo and his collaborators have developed a new method for tracking seed movement and germination. According to Carlo, the technique will be useful for studying plant dispersal and how plants adjust to global climate change. (13 October 2010)
- ScienceCast: An Interview with Tracy Langkilde About Stressed-Out Fence Lizards
- In this video, biologist Tracy Langkilde discusses her research on native fence lizards and their adaptive reactions to the presence of a novel threat, the invasive fire ant. (2 August 2010)
