A ‘time capsule for cells’ stores the secret experiences of their past

Описание: Scientists have successfully engineered TimeVaults, which are modified cellular organelles used to record and store messenger RNA over specific periods. By repurposing mysterious, barrel-shaped structures called vaults, researchers can now capture a molecular history of gene activity without pre-selecting specific targets. This innovation allows biologists to reconstruct past cellular events and observe how historical internal states influence a cell's ultimate fate. Practical applications of this technology have already helped identify how cancer cells survive drug treatments, revealing genetic activity that occurs before therapy even begins. Unlike previous gene-editing tools, these biological time capsules offer an unbiased way to archive a cell's life story for later sequencing. This breakthrough provides a continuous timeline of transcription, offering new insights into complex processes like stem cell differentiation and disease resistance.
