  • The dogs that work to detect cancer

    By Jack Ashby, on 22 November 2017

    The Grant Museum’s current exhibition – The Museum of Ordinary Animals: The Boring Beasts that Changed the World ­­- explores the mundane creatures in our everyday lives. Here on the blog, we will be delving into some of the stories featured in the exhibition with the UCL researchers who helped put it together.

    It’s 8.45am at a business park in rural Buckinghamshire, UK: my primary field site. A car pulls up and Kiwi jumps out, rushing into the workplace where she spends 3 days each week. Striding into the office, Kiwi wags her tail and greets her colleagues by pressing her wet nose into each of their trousers. Shortly after arriving, Kiwi is escorted by her trainer Sam to a grassy paddock where the pair stretch their legs. For Kiwi, this means darting across the field with her nose to the ground and choosing places to do her “business”. Meanwhile, armed with poop bags, Sam walks several laps of the paddock keeping a watchful eye on Kiwi. On their return to the office, Kiwi curls up on a cushion underneath Sam’s desk and dozes for an hour, before Sam calls her into the training room next door. Here Kiwi works, sniffing urine samples for up to 45 minutes per day as she learns to detect the odour of prostate cancer in urine.

    The Mechanical Leech – better than the real thing?

    By Jack Ashby, on 31 July 2012

    One of our team of post-graduate researcher/engagers (see what that’s all about on last week’s post) has been talking about the connection between species in the Grant Museum and a nineteenth century mechanical replica, which was designed as a clinical tool.

    It’s on the new Researchers in Museums blog, but to pique your interest here is how Sarah Chaney starts the post off…

    “Leeches! Leeches! Leeches!”
    So ran one particularly enthusiastic nineteenth century advertisement for the animal that has had the most enduring association with medical history. So much so, that one inspired individual decided to make a mechanical version of the creature. During my public engagement sessions in the Grant Museum, I’ve tried asking various visitors to guess what animal the fist-sized metal box was designed to emulate: no one has yet hit on the right answer, even though I usually stand right in front of the leech cabinet. Shiny, clean and angular, where the leech is squat, wet and slug-like, there would appear to be little comparison between the two.

    Indeed, that was the claim of certain nineteenth century leech advocates, who deemed the miraculous little creature itself far gentler than lancet, fleam or scarifier (also called a scarificator: the “mechanical leech” in the illustration, left). The leech secretes a substance called hirudin, which stops the blood from clotting, meaning that one small bite will continue to bleed for around 12 hours after the leech has been removed. I know this well, for, in the pursuit of medical history, I have been leeched not once, but twice, and still have the (tiny) scars to prove it!
