- A new pre-print titled “Time-tagged ticker tapes for intracellular recordings” (bioRxiv, 15 Oct 2021) was highlighted; it describes a protein-based “ticker tape” system that records a cell’s history of biological processes—such as neural activity—directly inside living cells, offering a potential route to high-resolution, molecular-scale logging of cellular events over time.

- The work was performed in the Adam Cohen laboratory and represents an advance toward non-electronic, genetically encodable memory for neuroscience and synthetic biology applications.
