As we all know, natural automatically means good. Nothing in nature has ever hurt anyone, ever.
In the first part of my series deconstructing the term ‘natural’, I talk genetically modified organisms and domestication, and ask what is really natural, anyway?
Virtually all mammals wisely choose to avoid eating chilli pepeprs and other foods that taste ‘hot’. New research shows that Chinese tree shrews have evolved to eat large quantities of chillies in their diet by tuning down their taste buds to the chemical that makes these foods hot.
I’d like to talk about a very important issue, very close to my heart, and one that I think needs greater public awareness – the definition of the word ‘bug’. See, people think they can just throw the word bug around willy-nilly. Anything small, flying or irritating, is a bug. Any pest, is a bug. […]
A warm welcome to the Curious Meerkat newsletter for November!
Welcome to the Curious Meerkat newsletter for October.
The summer is finally drawing to a close, and it’s time for the September Curious Meerkat Newsletter!
This month I finally published the first part of my new series, “There’s No Such Thing as Natural“, looking at genetically modified organisms and the connotations of the word “natural”.
Ticks feed on the blood of vertebrates, but this diet is low in B vitamins, which are vital for cellular metabolism. A study published earlier this year shows that African soft ticks (Ornithodoros moubata) supplement their diet with vitamin B from bacterial symbionts.
Parasites are thought to diversify with their host species, but the theory has rarely been tested. Kevin Johnson at the University of Illinois and his colleagues sequenced the genomes of 46 species of lice that parasitise birds or mammals, and two non-parasitic bark lice, and constructed an evolutionary tree. They estimated that parasitic lice first emerged between 90 and 100 million years ago, but didn’t begin to diversify until 66 million years ago – around the time of the dinosaurs’ extinction.
As I’ve mentioned before, living in a large densely-packed social group, like a city or an ant colony, comes with some drawbacks – perhaps worst of which is the risk of catching a contagious diseases. Earlier this year I wrote about research showing that raider ants treat injured workers’ wounds, helping them to heal. Now, a new study shows that the queen can pass on resistance to diseases she’s encountered, arming her workers against pathogens.
I’ve spent more time than most observing ants, and I’ve come to find them ‘cute’ – something few other people understand, and that is often hard to convey. So it’s nice to find a paper that offers the opportunity to give people a glimpse into the cuteness I see in ant behaviour.
Ants clean the wounds of injured nest mates, often saving their lives and keeping infection out of the colony.

Have you ever considered a world without elephants? This is a world we’re heading toward with the profound level of poaching that has occurred. As a result of almost institutionalized poaching over many decades, we have decimated the population of wild African elephants to between 400,000 and 600,000 individuals.
