Scientists in New Zealand and Japan have created a "tear-free" onion using biotechnology to switch off the gene behind the enzyme that makes us cry, one of the leading researchers said on Friday.
The discovery could signal an end to one of cooking's eternal puzzles: why does cutting up a simple onion sting the eyes and trigger teardrops?
The research institute in New Zealand, Crop and Food, used gene-silencing technology to make the breakthrough which it hopes could lead to a prototype onion hitting the market in a decade's time.
