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.
Researchers at the University of Sydney say they can turn the waste from durian and jackfruit into carbon aerogel, which can help store energy in what are called super-capacitors. And no, they don't smell.
Millennials are not really killing lunch. But an often-discarded piece of their beloved avocados may end up saving lunch, thanks to a new kind of cutlery made from bioplastics.
