A new DNA-based recorder allows bioengineers to create cell cultures that detect information in their environment and store it for later use. Such 'designer' cells might in the future be used to monitor water quality in a village, or measure the amount of sugar a person eats. The technique is described this week in Science1.
In synthetic biology, genes are engineered to regulate each other's expression in such a way that they can perform logic operations similar to those in computer circuits. Memory storage has long been considered one of the key components needed to fulfil the promise of this technology.
“Building gene circuits requires not only computation and logic, but a way to store that information,” says bioengineer Timothy Lu of the Massachusetts Institute of Technology in Cambridge. “DNA provides a very stable form of memory and will allow us to do more complex computing tasks.”
In previous synthetic-biology attempts, data storage has been laborious to create. It also recorded only the presence or absence of one particular sensory input, and could be used...

In the leadup to the 2024 election, Donald Trump repeatedly promised to make IVF more accessible. He made the commitment central to his campaign, even referring to himself as the “father of IVF.” In his first month in office, Trump issued an executive order promising to expand IVF access. The order set a 90-day deadline for policy recommendations for “lowering costs and reducing barriers to IVF,” although it didn’t make any substantive reproductive healthcare policy changes.
The response to the...
