The Ig Nobel Prizes is one of my favourite events of the year, and this year the winning research is particularly great. On the 14th September, The 27th First Annual Ig® Nobel Prize Ceremony & Lectures took place at Harvard University in Massachusetts. In case you’re not familiar with the awards, they were set up in 1991 to celebrate research that makes you laugh, and then makes you think. Here are this year’s awards:
I’d like to talk about a problem. It might seem like quite a small problem, but it’s a pervasive one. That problem, is salad.
Yes, that’s right, I said salad. Not high on the list of major world perils, but perhaps it should be. I mean, for starters, it’s everwhere. Lurking in every supermarket-bought sandwich, mocking you from the side of every pub lunch, withering beneath every take-away spring roll. And that sad bit of salad that came with your meal, that you never even for a moment considered eating, has caused a surprising amount of damage to the environment.
Can bees only sting me once?
Honeybees are generally killed by stinging you, but most other stinging insects can survive to sting you again.
It’s a common urban myth that bees can only sting once, but it’s partially based in truth. Honeybees have a barbed stinger, and if they sting a thick-skinned mammal like a human, the barbed hook gets stuck as they try to pull away, ripping their insides out and killing the bee within a few minutes. But if they were to sting another insect, or a vertebrate with thinner skin, they’d probably live to tell the tale.
You might have heard of the #360papers challenge – to read one journal article a day for a whole year – you might be less familiar with the related #230 papers challenge. This makes the more realistic goal of reading one journal article each working day of the year, which is apparently 230 days in total (I haven’t checked their maths). This is a record of my feeble attempt to reach this lofty goal – I will update every ten articles or so and try to give a one sentence summary (or link to an article or a longer blog).

New gene editing technologies have revolutionised genetic science, but social insects like ants have proved difficult to genetically modify because of their complex lifecycle and social structure. Now, two separate labs have succeeded in using the CRISPR-CAS9 system to genetically modify two unusual ant species, switching off genes and disrupting their social behaviour in the process.
Scientists bring marine plankton back to life to study past climate change
Phytoplankton such as are responsible for half the global primary production (GPP), and some form resting cysts that can lie dormant in marine sediments for up to a century. Earlier this year, scientists succeeded in making use of these cellular time-capsules to understand changing ocean conditions in a Swedish fjord.
Colour exists on a continuum, and yet human language is surprisingly consistent in how it categorises colours.
Previous studies have found that infants at the age of four months old can distinguish the basic colour categories common to many languages (e.g. blue, red, yellow), suggesting there is a biological basis to our color categories. However, these studies have focussed on just a few color categories that are important in English.
Infant mongooses rely on adults to escort them as they learn to forage. A new study from the University of Exeter reports that adult mongooses show no preference for their own offspring when choosing a pup to escort, and the authors suggest they may not be able to tell their own kin apart.
House mice outcompeted their wild relatives to become domesticated as soon as long-term human settlements appeared, some 5000 years before agriculture took hold.
The advent of farming marks a huge change in human populations – a change in diet, social structure and a switch to a more sedentary lifestyle. Agriculture also had a profound impact on wild animals, and is thought to have led to the domestication of many species, from wolves to cattle and chickens. But other species became domesticated accidentally – as humans started storing grain for lengthy periods of time, the house mouse adapted to thrive in this new ecosystem. Now, a new study shows that it was our sedentary lifestyle, not agriculture, that domesticated one of our most prolific pests.
