A team of researchers supported by the U.S. National Science Foundation has successfully made self-growing microlenses using bacteria and enzymes found in sea sponges. Because the microlenses are created by bacterial cell factories that function at standard temperatures and pressures, they are less expensive to produce — and they are exceptional at focusing light into very bright beams. The microlenses could allow for higher-resolution image sensors that go beyond current capabilities, potentially allowing doctors to more clearly see tiny structures inside cells.
In nature, sea sponges mineralize silica-based glass at a cellular level to create their intricate and strong glass skeletons. The researchers replicated that mechanism in a lab setting. Their research was published in Proceedings of the National Academy of Sciences
“This research is the first to engineer light-focusing properties into bacteria cells, and I am excited to explore the different possibilities that our work has opened up,” says one of the study’s authors and University of Rochester researcher Anne S. Meyer.

Postdoctoral Research Associate Post Doctorate Research Opportunity Multifunctional Materials Modeling and Experimental Characterization
Florida Center for Advanced Aero-Propulsion (FCAAP) Florida A&M—Florida State University (FAMU-FSU) College of Engineering Department of Mechanical Engineering Tallahassee, FL 32310
A post doctorate research opportunity is currently available in the Mechanical Engineering Department and the Florida Center for Advanced Aero Propulsion (FCAAP) at the joint FAMU-FSU College of Engineering. The researcher will work within an interdisciplinary group at FAMU-FSU and the University of Florida through a Center of Excellence on Sense, Assess, Respond for high speed aircraft. https://fcaap.fsu.edu/aeromorph/
The research is focused on the application of information theory and applied mechanics to understand dynamical complexity in multifunctional materials and adaptive structures interacting with high speed fluid flow. It includes applying relationships between multifractal spatial and temporal structure with properties in physical reservoir computers that interact with fluid dynamics. It builds
