Researchers at Mayo Clinic have developed an aptamer-based technique to tag senescent, or so‑called “zombie,” cells in living mouse tissues, work they say could eventually support targeted therapies for age‑related diseases. The project grew out of a chance conversation between two graduate students, according to Mayo Clinic.
Researchers at The University of Osaka have developed ultra-small pores in silicon nitride membranes that approach the scale of natural ion channels. These structures enable repeatable opening and closing through voltage-controlled chemical reactions. The advance could aid DNA sequencing and neuromorphic computing.

Researchers have achieved the most detailed imaging yet of chromatin condensates, revealing how DNA fibers fold and interact within these droplet-like structures. The findings link molecular arrangements to the overall behavior of these condensates in cells. This work builds on earlier discoveries about DNA packing mechanisms.
