Upside-down rhino research wins Ig Nobel Prize

An experiment that hung rhinoceroses upside down to see what effect it had on the animals has been awarded one of this year’s Ig Nobel prizes.
Other recipients included teams that studied the bacteria in chewing gum stuck to pavements, and how to control cockroaches on submarines.
The spoof prizes are not as famous as the “real” Nobels – not quite.
The ceremony couldn’t take place at its usual home of Harvard University in the US because of Covid restrictions.
All the fun occurred online instead.
The science humour magazine, Annals of Improbable Research, says its Ig Nobel awards should first make you laugh but then make you think.
And the rhino study, which this year wins the award for transportation research, does exactly this. What could seem more daft than hanging 12 rhinos upside down for 10 minutes?
But wildlife veterinarian Robin Radcliffe, from Cornell University, and colleagues did exactly this in Namibia because they wanted to know if the health of the animals might be compromised when slung by their legs beneath a helicopter.

It’s an activity that increasingly has been used in African conservation work to shift rhinos between areas of fragmented habitat.
However, no-one had done the basic investigation to check that the tranquillised animals’ heart and lung function coped with upside-down flying, said Robin.
He told BBC News: “Namibia was not the first country to move rhinos upside down with helicopters, but they were the first to take a step back and say, ‘hey, let’s study this and figure out, you know, is this a safe thing to do for rhinos?”
And so, his team, in collaboration with the Namibian Ministry of Environment, Forestry, and Tourism, suspended 12 tranquillised black rhinoceroses by their feet from a crane, and measured their physical responses.© Namibian Ministry of Environment It’s actually better for the rhino to be held by its ankles than put on its side
It turns out, the animals coped very well. In fact, there was evidence the rhinos did better in this usual position than simply lying chest down or on their side.
“I think the reason for that is, when a rhino is on its side, you have positional effects of blood flow. So in other words, the lower parts of the lung are getting lots of blood flow for gas exchange, but the upper part of the lung, just because of gravity, is not getting perfused well, so when a rhino is hanging upside down, it’s basically like it’s standing upside up; the lung is equally perfused.
“We’ve also seen that rhinos that are on their side too long, or on their sternum, especially – they get muscle damage, they get myopathy, because they’re so heavy. And there’s no pressure on their legs, other than the sense of the strap around their ankle,” Robin explained.
As has become customary with the Ig Nobels, the prizes on the night were handed out by real Nobel laureates, including Frances Arnold (chemistry, 2018), Marty Chalfie, and Eric Maskin (economics, 2007).
The winners got a trophy they had to assemble themselves from a PDF print-out and a cash prize in the form of a counterfeit 10 trillion dollar Zimbabwean banknote.
Asked what he’d do with his cash payout, Robin Radcliffe said with a chuckle: “We are always looking for grant funding.
“When I first heard about the Ig Nobel, I wasn’t sure if this was good or bad. But I think that message that ‘it makes you laugh and then think’ – this is what it’s about for us. More and more people should understand what efforts are going on to try to help save these amazing animals that live here on Planet Earth with us.”
The full list of 2021 Ig Nobel award winners:
Biology Prize: Susanne Schötz, for analysing variations in purring, chirping, chattering, trilling, tweedling, murmuring, meowing, moaning, squeaking, hissing, yowling, howling, growling, and other modes of cat-human communication.
Ecology Prize: Leila Satari and colleagues, for using genetic analysis to identify the different species of bacteria that reside in wads of discarded chewing gum stuck on pavements in various countries.
Chemistry Prize: Jörg Wicker and colleagues, for chemically analysing the air inside movie theatres, to test whether the odours produced by an audience reliably indicate the levels of violence, sex, antisocial behaviour, drug use, and bad language in the movie the audience is watching.
Economics Prize: Pavlo Blavatskyy, for discovering that the obesity of a country’s politicians may be a good indicator of that country’s corruption.
Medicine Prize: Olcay Cem Bulut and colleagues, for demonstrating that sexual orgasms can be as effective as decongestant medicines at improving nasal breathing.
Peace Prize: Ethan Beseris and colleagues, for testing the hypothesis that humans evolved beards to protect themselves from punches to the face.
Physics Prize: Alessandro Corbetta and colleagues, for conducting experiments to learn why pedestrians do not constantly collide with other pedestrians.
Kinetics Prize: Hisashi Murakami and colleagues, for conducting experiments to learn why pedestrians do sometimes collide with other pedestrians.
Entomology Prize: John Mulrennan Jr and colleagues, for their research study “A New Method of Cockroach Control on Submarines”.
Transportation Prize: Robin Radcliffe and colleagues, for determining by experiment whether it is safer to transport an airborne rhinoceros upside down. AdChoices
