Aquatic playground can turn water tanks into fish schools
Juvenile Atlantic salmon raised in tanks with hiding places and floating artificial plants showed signs of improved brain function and could better navigate mazes than the salmon reared in standard hatchery tanks. Image: Anne Gro Salvanes

Using interdisciplinary tools to find cure for human herpesvirus
Paired fluorescence and phase (white light) images of uninfected neurons (top and bottom left) and neurons infected with HSV (top and bottom right). As is clearly visible in the white light images, these neurons form dense networks of connections. Fluorescent dyes can be used to stain and highlight the individual filaments of these networks (top left) as well as to detect a specific viral protein expressed during HSV infection (top right).

Biologist investigates lasting ecological impacts of Deepwater Horizon oil spill
This photo, taken as part of a major research project led by Penn State Professor of Biology Charles Fisher, shows a reef formed by the coral species Lophelia pertusa at 450m below the surface of the Gulf of Mexico with an orange brisingid starfish in the foreground and a school of fish overhead.

Infectious Disease Research Gets a Boost from Websites, Blogs, and Social Media
An article by Marcel Salathé and his colleagues in the New England Journal of Medicine describes a new field of research known as digital epidemiology. This field is of increasing importance for tracking outbreaks of infectious diseases such as the one caused by a novel coronavirus, pictured here.

Genome instability studies could change treatment for cancer and other diseases
The genome is an organism’s complete set of DNA and is organized into chromosomes containing genes that encode for hereditary traits. Researchers at Penn State are studying mutations that cause inherited cancers and other hereditary diseases. Credit: Oak Ridge National Laboratory
Nanoparticle Opens the Door to Clean-Energy Alternatives
A transmission-electron microscope image of a collection of quasi-spherical nickel phosphide nanoparticles. A team led by Raymond Schaak of Penn State University has found that these nanoparticles can catalyze an important chemical reaction that generates hydrogen from water.

Alzheimer's, Schizophrenia, and Autism Now Can Be Studied with Mature Brain Cells Reprogrammed from Skin Cells
Human neural stem cells (shown in red), reprogrammed originally from adult skin cells, differentiate efficiently into brain cells (shown in green), after being cultured with star-shaped cells called astrocytes. Credit: Chen lab, Penn State University.
New Kind of Antibiotic May Be More Effective at Fighting Tuberculosis, Anthrax, and Other Diseases
Bacillus anthracis (anthrax) cells being killed by a molecule studied by Penn State University researcher Kenneth Keiler. The molecule is naturally fluorescent and it looks blue when it is excited by ultraviolet light in the microscope. Keiler and his team found that certain molecules inhibit the growth of very distantly related bacteria by stopping trans-translation, which is a quality control mechanism that is found in all species of bacteria.
