Researchers at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, report in ACS Applied Nano Materials a new method to precisely measure nuclear elasticity—the stiffness or softness of the cell nucleus—in living cells. By employing a technique called Nanoendoscopy-AFM (NE-AFM), which inserts a nanoneedle probe directly into cells, the team revealed how cancer cell nuclei stiffen or soften depending on chromatin structure and environmental conditions.

The findings provide fundamental insights into how the physical properties of cancer cell nuclei change during disease progression, highlighting their potential as biomarkers for diagnosis and treatment evaluation.

A new study found that firefighters exposed to the Palisades and other fires had changes in their immune system and inflammatory response protein pathways.
