COLUMBIA, Mo. – The flow of traffic through our nation’s highways and byways is meticulously mapped and studied, but less is known about how materials in cells travel. Now, a team of researchers at the University of Missouri is challenging prior theories about how material leaves the inside of an E.coli cell. This discovery could have important implications for how we treat diseases.
What do you know about cells, the fundamental structural unit of plant and animal life? All living cells have membranes that protect cellular integrity while controlling the flow of information and materials into and out of cells. A major component of cell membranes is lipid molecules, which form bilayered structures, while most of the work done inside cells is performed by proteins, linear molecules built from 20 different amino acids.
In applying for the NSF award, MU physics professors Suchi Guha (top) and Ping Yu said the transdisciplinary breadth of available expertise is unmatched in the region, “empowering STEM students to obtain a competitive edge by hands-on experiences, and preparing them for employment in nanotechnology, biotechnology, materials science and engineering, and semiconductor-based academic research or industry.”
A University of Missouri team of researchers has been awarded a Major Research Instrumentation award from the National Science Foundation (NSF) that will allow the team to purchase an ultrafast amplified laser system that will facilitate research in condensed-matter physics, material science and engineering, chemistry, chemical engineering, biology, bioengineering, and medicine.
Gavin King, an associate professor of physics, is trying to understand one of the most basic concepts in cell biology: secretion, or the mechanism by which proteins can pass through a cell membrane to get from one compartment of a cell to another. Membrane proteins are the “gatekeepers” that allow information and molecules to pass into and out of a cell.
The U.S. Department of Energy (DOE) is funding cutting-edge research into new magnetic materials and the theory of spinning electrons that could lead to better data storage and processing and more efficient magnetic resonance imaging (MRI) for radiologists, and it may even have implications for quantum computing. MU physics professors David Singh and Carsten Ullrich were recently informed they have won DOE grants to pursue their research.
Frontiers in Magnetic Materials
Singh calls magnetism one of the most remarkable and diverse properties of matter.
A mathematical model developed by a new faculty member at Mizzou could become a tool for early detection of vascular abnormalities of the eye. Professor Giovanna Guidoboni, who holds a joint appointment in electrical engineering, computer science, and mathematics, says her research began in 2010 while she was a professor of mathematical sciences at Indiana University–Purdue University Indianapolis (IUPUI). That’s when she met her collaborator, Professor Alon Harris, director of clinical research at the university’s Eugene and Marilyn Glick Eye Institute.
MU Curator’s Teaching Professor of Physics Meera Chandrasekhar and her colleagues, Teaching Professor Dorina Kosztin and Assistant Teaching Professor Karen King, spent six years training ninth-grade science teachers in Missouri to become intellectual leaders of their schools under the National Science Foundation–funded program, A TIME for Freshman Physics in Missouri, commonly called Physics First.
COLUMBIA, Mo. – Ayurvedic medicine (also called Ayurveda) is one of the world’s oldest medical systems. Originating in India more than 5,000 years ago, this holistic medicine system uses herbal compounds, special diets and other health care practices to augment conventional preventative and disease treatments. Now, Kattesh Katti, a researcher at the University of Missouri, has developed a non-toxic delivery method using gold nanoparticles that may revolutionize Ayurveda.
