Four-dimensional physics in two dimensions
Illustration of light passing through a two-dimensional waveguide array. Each waveguide is essentially a tube, which behaves like a wire for light, inscribed through high-quality glass using a powerful laser. Many of these waveguides are inscribed closely spaced through a single piece of glass to form the array. Light that flows through the device behaves precisely according to the predictions of the four-dimensional quantum Hall effect. CREDIT: Rechtsman laboratory, Penn State University
Alien Megastructure not the cause of dimming of the 'Most Mysterious Star in the Universe'

Agricultural parasite takes control of host plant’s genes
Dodder, a parasitic plant, attached to a host plant from which it obtains water and nutrients. The parasite inserts microRNAs into the host that can silence the expression of host genes. This is the first example of cross-species gene regulation observed in a parasitic plant. CREDIT: Penn State University
Understanding enzyme cascades key to understanding metabolism
Like ants, one enzyme follows the trail left behind by the previous one. In this case, the initial substrate is acted upon by enzyme A, leaving a substrate suitable for enzyme B and on down the line. Credit: Ayusman Sen

Mathematical model mimics melanoma
Mathematical model mimics melanoma. Left: melanoma cells grown in culture with normal cells form clusters that resemble proto-tumors. Right: Simulations using a modified version of the Widom-Rowlinson model replicate patterns of melanoma cell growth seen in laboratory experiments by controlling the exclusion area -- the amount of space required -- around two types of simulated cells as they grow and spread.

Flies' disease-carrying potential may be greater than thought, researchers say
A study initiated at Penn State’s Eberly College of Science adds further proof to the suspicion that houseflies and blowflies carry and spread a variety of species of bacteria that are harmful to humans. The housefly pictured above was taken in Singapore.
