Don’t poke that avocado
Here’s something that just sounds … well, dopey. Testing avocados for ripeness involves physically pressing them, which destroys up to 30 percent of the crop.
Enter engineers at Cranfield University, who — like all good engineers — know that lasers make everything better. So they developed a way of using lasers to test avocados for ripeness without damaging them. (Then, just to sound extra-science‑y, they “test the individual fruits’ resonant frequency” and called the process “laser Doppler vibrometry”.)
