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.

Super-dense Star is First Ever Found Suddenly Slowing Its Spin
A neutron star is the densest object astronomers can observe directly, crushing half a million times Earth's mass into a sphere about 12 miles across -- roughly the size of Pittsburgh, or the distance between the Penn State University Park Campus and Bellefonte, Pennsylvania, as shown in this illustration.
