If you look at the back of a credit card, a driver’s license, or even a dollar bill, you will likely notice a hologram, or iridescent feature, that appears to change color when viewed at different angles. These color-shifting security features have been around for decades, allowing ample time for people to find ways of counterfeiting the effects. Even so, these types of highly visible and easily recognized color-shifting features are still among the most commonly used optical security element – and Penn State-affiliated startup Chromatir may have discovered a more secure and customizable w...

IMAGE: Provided Anand was awarded LB2C funding for his project titled “Targeting Virus Breathing Hotspots for Antibody Discovery.” Anand looks for vulnerabilities on a virus that could be tapped to generate antibodies for use in antiviral therapies. He is particularly interested in understanding the structural changes of viral surface proteins as the virus dissembles and enters human host cells. These structural changes — part of a process called viral breathing — could reveal critical locations — called epitopes — where antibodies can bind to the virus. Anand will then work with ...
