EXCERPT:
Your cells could soon keep an accurate record of their entire biological history, including attacks from microbial invaders or exposure to harmful chemicals.
By tweaking DNA, US researchers have been able to store markers of biological events inside the cells themselves and read them at a later date, essentially turning cells into analogue recorders.
They believe that capturing the ‘memories’ of these biological events could help to shed light on disease and even unlock the secrets of how cells develop from an embryo to the billions of adult cells which make up the human body.
