Emory University graduate student Ekram Towsif and Professor Shashank Shekhar have uncovered groundbreaking insights into the dynamics of actin filaments and the multifunctional actin-binding protein cyclase-associated protein (CAP). Using cutting-edge biophysical techniques, including microfluidics-assisted TIRF microscopy and multispectral single-molecule imaging, their research reveals CAP’s previously unknown role as a processive depolymerase at the barbed ends … More How to Unwind Both Ends of Actin Filaments

In a recent paper in PRX Life, Prof. Nemenman and collaborators explore intrinsic motivation — the ability of biological or artificial agents to learn new skills without an explicit reward. They introduce a new method that can compute a certain quantity, called empowerment, which has been proposed as a good proxy for intrinsic motivation. Empowerment maximizes … More Doing Without Choosing: The Physics of Intrinsic Motivation

Associate Professor Justin Burton was recently recognized with 2 separate acheivements for his scholarly research and contributions to the physics community. First, he was chosen as a Winship Distinguished Research Professor. Winship professors are tenured faculty (generally associate professors showing stellar progress toward promotion to full professor, or recently promoted full professors on a steep upward … More Prof. Justin Burton selected as a Winship Professor and receives APS Fellowship

Excited carriers in noble metal nanostructures have recently attracted considerable attention for photocatalysis, optical detection, and photonic circuitry. However, most nanoarchitectures fail to yield highly energetic carriers, which are usually necessary for these applications. The main reason for this bottleneck is the inefficiency of intraband carrier absorption in metals, dictated by momentum conservation. Due to … More Squeezing light strikes gold in photonics
