Trophic shadows and the tyranny of the energy pyramid
Ernest Rutherford, the famous physicist, supposedly claimed that “Science is either physics or stamp collecting”. At the cost of no longer being welcome in the biology department Rutherford was making the point that everything is subject to the laws of physics and ultimately these laws can describe any natural phenomenon. In real life we usually Continue reading

Pork, another red meat
Fear is a great motivator and, being in the business of motivation, advertising has always been very quick to take advantage of human uncertainty to build demand. An example of this is the famous “The other white meat” campaign for pork that ran in the States in 1987 and was copied here in Australia during Continue reading

Bananas, uniformity and catastrophe
I’ve been reliably informed by influencers, billionaires, failed comedians, politicians, Twitter pundits and assorted spite-filled meat-puppets looking to build an audience that diversity is a bad thing. Now I’m not one to disagree with the new intelligentsia but as a scientist, a member of the old intelligentsia I guess, I can’t help but feel, deep Continue reading

A requiem for bacon
On October 26, 2015 the International Agency for Research on Cancer (IARC) broke my heart. I know this sounds dramatic and maybe even a little silly.

Quick Bite: How salt enhances the flavour of our food
In my recent post on MSG and our taste perception I was going to include a bit about salt and how it works as a flavour enhancer but, as usual, I went on a bit so I couldn’t fit it in. So I wanted to do this short post while it was all fresh in Continue reading

The science behind umami: Understanding the way we perceive taste
Most of us have now heard of umami and we probably all know that umami is now recognised as the fifth of our primary tastes, formerly limited to sweet, sour, bitter and salty. You might also know that Western societies were a bit slow to the umami party. Despite being recognised in the East for Continue reading

Starch and Gelatinisation in Everyday Cooking
I’m no historian but I think it would be fair to say that for most of history most humans relied primarily on starchy grains and vegetables to keep themselves and their families fed. Grasses like wheat, rice, oats and barley are easy to grow and the seeds, or grains, of these grasses are rich in Continue reading
