Ohio State researchers captured unprecedented snapshots of a DNA repair protein tied to BRCA‑driven cancers. Using state‑of‑the‑art cryo‑EM at CEMAS, they revealed how it repairs DNA, insights that could guide targeted cancer drugs. news.osu.edu/best-snapshots…

CEMAS recently welcomed Krishna Chinthalapudi, Associate Professor of Physiology and Cell Biology, as the new Associate Director of Biological Sciences! This new strategic role supports the growing demand for advanced biological imaging and cryo‑EM. cemas.osu.edu/news/2026/04/c…

New insight from CEMAS 📷 Using HRSTEM HAADF imaging, researchers can see the nucleation of a complex carbide within a microtwin in the fcc matrix of an additively manufactured Ni‑based superalloy. Postdoc Andreas Bezold was able to capture this image on CEMAS' Themis Z S/TEM.

Recent work published in Nature Communications reports high‑resolution structural characterization of the human cardiac sodium channel Nav1.5, enabled by advanced cryo‑electron microscopy conducted at CEMAS. Read the full article: nature.com/articles/s4146…

The paper demonstrated that alloying Mg with Ca shows promise in weakening deformation and recrystallization texture that can be associated with increased ductility and formability. doi.org/10.1016/j.jma.…

These experiments were performed by graduate student Rogine Gomez in the Leonard research group in MSE with CEMAS Senior Research Associate Daniel Veghte. Recrystallization and growth are observed from the heavily deformed areas (initially non-indexable areas).

Happy #MicroscopyMonday 🔬 In-situ electron backscatter diffraction (EBSD) experiments were performed in the scanning electron microscope (SEM) during heating of a heavily deformed magnesium alloy.

What appear to be the “ears” are actually regions outlined by colloidal silica left behind during polishing and final cleaning. The “eye” is a void, and the rest of the “mouse” takes shape along the alloy’s grain boundaries.

Check out the research SEM image that turned out unexpectedly artistic when a mouse appeared, taken by graduate student Nicole Hudak! Captured on Apreo 1/2 using standard conditions, it’s a BSE image of a titanium alloy. It takes a bit of imagination to see the tiny creature 🔬
