Critical Protein Discovered for Healthy Cell Growth in Mammals
Using mouse models, Penn State cellular biologist Aimin Liu and his colleagues discovered a protein that is required for the growth of critical, hair-like structures called cilia on cell surfaces. The cilia on a mouse embryo, shown in this micrograph, would not be able to grow without the protein C2cd3. Credit: Aimin Liu Lab, Penn State University.

A New Pathway for Neuron Repair is Discovered
This image shows a single neuron in a whole animal 5 hours after dendrites were removed with laser surgery (left). The same cell was imaged at 48 hours and 96 hours after the dendrites were removed. At 48 hours (middle) a new dendrite arbor extends from the cell body, and by 96 hours the new arbor fills the entire space normally occupied by the cell.

Brain Repair after Injury and Alzheimer's Disease: In vivo reprogramming of reactive glial cells into functional neurons
Researchers at Penn State University led by biologist Gong Chen have developed an innovative technology to regenerate functional neurons after brain injury, and also in model systems used for research on Alzheimer's disease.

Marine Biologists Unmask Species Diversity in Coral Reefs
Two corals (Porites sp.) growing side by side.The left colony is bleached: it appears white. During bleaching the partnership between symbiotic algae that live inside the coral cells and the coral host breaks down giving the coral a white appearance. The colony on the right is still green/brown and has a healthy population of symbionts living in its tissue. Photo credit: Iliana Baums, Penn State University.
