Penn Medicine Biochemist Awarded $2.5 Million Grant for New Microscope Technology

Marmorsteinheadshot2017.jpg

Ronen Marmorstein, PhD, a professor of Biochemistry and Biophysics in the Perelman School of Medicine at the University of Pennsylvania, is one of five investigators who received a grant from the Arnold and Mabel Beckman Foundation for the creation of a state-of-the-art cryogenic electron microscopy (cryo-EM) facility. The investment supports research in chemistry and the life sciences and will also go towards maintaining the cryo-EM facilities and hiring of new faculty skilled in its uses.

TSRI Scientists Find Simple Copper Complex Shuts Down Botulinum Neurotoxin Poisoning

Clostridium botulinum is the bacterium that causes the neurointoxication, which produces one of the most potent toxins on earth and is classified as a potential bioterrorism threat. While no cure exists—and botulism treatment options are limited—a serendipitous discovery by scientists at The Scripps Research Institute (TSRI) may provide a new therapy that can stop the neurotoxin even in its more severe, advanced stages of action.

A new study looks at how three varieties of camelina perform when grown in two different regions within the Great Plains. The end goal is to find the camelina variety that performs best in each location or environment--beyond the genetics involved.

Neutrons Provide the First Nanoscale Look at a Living Cell Membrane

A research team from the Department of Energy’s Oak Ridge National Laboratory has performed the first-ever direct nanoscale examination of a living cell membrane. In doing so, it also resolved a long-standing debate by identifying tiny groupings of lipid molecules that are likely key to the cell’s functioning.

Researchers Suppress Fibrosis Chemical Signal to Block Haywire Healing

ROCHESTER, Minn. ─ An injured body always seeks to heal. But that process is far from simple. A host of cells organize to restore what was damaged. Then, critically, the process tapers off. And when it doesn’t, the effects can be disastrous. Fibrosis is the thickening and scarring of tissue due to an overactive healing response.

A new process triples the fraction of biomass converted to high-value products to nearly 80 percent, also tripling the expected rate of return for an investment in the technology from roughly 10 percent (for one end product) to 30 percent.

Using neutron crystallography, a Los Alamos research team has mapped the three-dimensional structure of a protein that breaks down polysaccharides, such as the fibrous cellulose of grasses and woody plants, a finding that could help bring down the cost of creating biofuels.
