A joint venture between the Huck Institutes of the Life Sciences and the Materials Research Institute, the Cryo-Electron Microscopy Facility houses a one-of-a-kind FEI Titan Krios microscope that offers uncompromised data collection for the life sciences while incorporating materials science applications. Specifically, the facility allows for fully-automated atomic-resolution single-particle and high-contrast tomography tilt-series data collection. Additional microscopy components permit a full range of materials science applications, including EELS, STEM, and DPC.

Essential process for SARS-CoV-2 viral replication visualized
During the replication of the SARS-CoV-2 virus, a long string of connected proteins is cleaved apart into individual proteins. This process is interrupted by an FDA-approved drug to treat COVID-19; however, the mechanistic details of this cleavage process are still unclear. Now, a team led by researchers at Penn State has produced the most detailed images to date of this process, revealing that these proteins are cleaved in a consistent order likely dictated by the structure of the protein string.
How does an aging-associated enzyme access our genetic material?
New research provides insight into how an enzyme that helps regulate aging and other metabolic processes accesses our genetic material to modulate gene expression within the cell. A team led by Penn State researchers have produced images of a sirtuin enzyme bound to a nucleosome — a tightly packed complex of DNA and proteins called histones — showing how the enzyme navigates the nucleosome complex to access both DNA and histone proteins and clarifying how it functions in humans and other animals.
DNA stuck in the gears of the RNA production machine
Precise control of gene expression — ensuring that cells make the correct components in the right amount and at the right time — is vital for all organisms to function properly. Cells must regulate how genes encoded in the sequence of DNA are made into RNA molecules that can carry out cellular functions on their own or be further processed into proteins.

Researchers film human viruses in liquid droplets at near-atomic detail
A research team led by Deb Kelly, Huck Chair in Molecular Biophysics and professor of biomedical engineering at Penn State, has used advanced electron microscopy (EM) technology to see how human viruses move in high resolution in a near-native environment. The visualization technique could lead to improved understanding of how vaccine candidates and treatments behave and function as they interact with target cells, Kelly said.
