In China, under the site of a planned airport, was found a container of food that is 2,400 years old. A short article about this find is at the BBC website. They're doing tests to find out what was in it - I wonder what tests. This is the thing with non-academic articles when you know something about (or have done 5 years worth of study on...) a subject. I will have to keep on eye out for any other posts about it to find out more!
And on further inspection, io9 has done an article on this, that I will read tomorrow. Here's the link though.
