An engineer and beekeeper in New England has developed a system using radar and vibrational sensors to detect when a hive is being robbed by a rival colony, or when some of the bees are about to leave and start their own colony. That should create a buzz among beekepers!
A sensor developed at MIT uses a set of microneedles to push through packaging and determine whether the food inside is safe to eat, which could prevent food waste and help head off outbreaks of salmonella.
A team of engineering students at Harvard is teaming with a startup called Savormetrics to develop a device that can tell us when avocados will be ripe. It's one step on the way to solving the costly problem of food waste.
A research team at Imperial College London has developed food freshness sensors that can be embedded in the packaging of meat and fish and detect the gases that show up when food spoils.
