Quick Bite: New research shows what was on the menu 2 million years ago
The Ship of Theseus is the name given to a thought experiment first related by Plutarch around the beginning of the second century. In this story the ship Theseus rescued the children of Athens with was kept by the people of Athens and used every year in a pilgrimage to Delos. Over time, and many Continue reading

Aphrodisiacs: Can food make you sexy?
Sex has always been something of a problem for human societies. Love, marriage, children and the passage of assets from one generation to the next has always been a primary human preoccupation. Yet in all these endeavours sex and sexual attraction lurks like the drunk uncle at a wedding; unpredictable, inconvenient but impossible to ignore. Continue reading

Quick Bite: You say tomato, I say potato
On the face of it a tomato and a potato are two very different things. One a fruit, soft and bursting with juice and flavour. The other a tuber that grows underground, hard but packed with starch ready to become a delicious source of nutrients after some judicious cooking. Despite this some new research shows Continue reading

Hunger games: Why we get hungry and why we overeat
Imagine you are driving down a long and lonely highway. You are late but also conscientious, so you want to stick as closely to the speed limit of 100 km/h as you can. For the purposes of this story your cruise control is broken or you don’t don’t trust Tesla’s self driving function so you Continue reading

Quick Bite: Ultra-processed foods give you lung cancer? Maybe not
In the past I’ve been critical of both observational studies and the reporting of these studies in the media and yesterday the Independent published an article called “Food that makes up more than half of western diets linked to lung cancer” which really pushed my buttons. The title is clearly link-bait and it had me Continue reading

Saffron: The duplicitous golden spice
Humans have always displayed enormous ingenuity when it comes to short-changing their fellow man. Modern tech companies, with their opaque terms of service and relentless data farming, are a great recent example of this but to capture the eternal nature of man’s duplicity we need look no further than our daily repast. Since antiquity we Continue reading

Vitamin D and human individuality
In a world that seems hell bent on pigeon-holing us into convenient advertising demographics it is worth remembering that almost every single one of us is completely unique. Thanks to sexual reproduction and genetic recombination each of us is an experiment in what can be achieved with the raw clay of the human gene pool. Continue reading

Bacterial growth or how not to kill your dinner guests
There is an old Indian parable of a king who wanted to reward a wise man who had invented chess. The wise old man asked for rice but had an unusual stipulation when was asked how much rice he wanted. He requested a single grain of rice to be put on the first square of Continue reading

Oxygen, electrons and Scottish chefs: How understanding redox reactions could save you from a bollocking
Many years ago I was working in a restaurant in Scotland and in an effort to save myself some time I prepped a stack of apples we were using as a garnish hours before we needed them. Thinking I’d done something clever I was radiating smugness until a coworker pointed out that the apples would Continue reading

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. International research agencies don’t go around breaking peoples’ hearts. How can I justify this outrageous statement? Well it was on this day that the IARC issued a press release Continue reading

Stewing like a medieval peasant: How to deal with the the tougher cuts
Of all the wonders of the modern world I think that a supermarket would be the thing that would inspire the most awe in a time-travelling medieval peasant. The availability of spices would be one thing. Our vast range of ultra-processed ready-to-eat meals would be another. But the ability to walk into a supermarket and Continue reading
