Science

The breakthrough allowed scientists, for the first time in a laboratory setting, to recreate the complete process through which the heart generates and carries electrical signals that control its rhythm. The lab-grown tissue also closely matched human embryonic sinoatrial node cells in gene activity and reacted correctly to medications used to control heart rate.

The findings could help pave the way for future biological pacemakers based on transplanted cells or organoids, potentially offering an alternative to traditional electronic devices. Conventional cardiac pacemakers, which use electrical pulses to regulate the heartbeat, have been widely used in medicine for more than 50 years and remain one of the most common treatments for patients suffering from dangerous heart rhythm disorders or irregular heartbeats.

To my sensibilities it seems a bit premature to speculate about what an actual medical product would look like. Seems very involved to get custom bio implants that won't get rejected/harvesting ones stem cells to vibe code them into a nerve cluster and then replace the one that's already there and difficult to reach.

Not to say it's not intensely impressive, pushing forward the frontier, and immediately useful as a model. It is amazing to read about. It just seems as likely to not develop into a product or develop into a different product from here in my eyes.
