Summary:
- This article discusses a new technology called "heartbeat imaging" that can be used to assess the freshness of oysters.
- The technology works by using a camera to detect the subtle movements of an oyster's heart, which can indicate how recently the oyster was harvested.
- This method is more accurate and reliable than traditional methods of assessing oyster freshness, such as checking the shell or the smell, and could help ensure that consumers are getting the freshest possible oysters.
