Healthy cells have their own version of Chinese finger traps, called catch-bonding. These bonds are formed by protein molecules at the cell surface, and the greater the force pulling them apart, the longer the bond between them lasts. Assistant Physics Professor Mike Hinczewski, who received a $656,866 award, will develop theories help uncover the structural details of catch-bonding from experimental data. 'The heart of this project is to figure out how catch-bonding occurs in a variety of protein systems in very different biological contexts,' he said. 'Can all these systems be described by similar mechanisms?' Catch bonds have been found in proteins that recruit white blood cells from a rushing blood stream, as well as at the junctions between neighboring cells in tissues, Hinczewski explained. The mechanical forces which naturally occur in these cases, due to the fluid flow or the tension in the tissue, change the protein shape, increasing the bond lifetime. 'Researchers are just beginning to explore in depth how force regulates adhesion between cells and its potential implications for the human immune system and diseases like cancer,' he said. Hinczewski's lab will use feedback between theory and data to develop mathematical and structural models, elucidating these counter-intuitive protein finger traps.

CWRU Researchers Directly Measure how Perovskite Solar Films Efficiently Convert Light to Power
Solar cells made with films mimicking the structure of the mineral perovskite are the focus of worldwide research. But only now have researchers at Case Western Reserve University directly shown the films bear a key property allowing them to efficiently convert sunlight into electricity. Identifying that attribute could lead to more efficient solar panels. Electrons generated when light strikes the film are unrestricted by grain boundaries - the edges of crystalline subunits within the film - and travel long distances without deteriorating, the researchers showed. That means electric charge carriers that become trapped and decay in other materials are instead available to be drawn off as current.
