Researchers switch on genes with blue pulse

Scientists have developed a technique that could be used to deliver precise doses of hormones to people who don’t make them naturally.

To do this, they rewired kidney cells with light-sensitive molecules from the eye, they reported in the journal Science.

When pulsed with blue light, these cells churned out proteins on demand.

Ultimately, this technique could avoid the need for people with diabetes to inject themselves regularly.
