The Ig Nobel Prizes honour achievements that first make us laugh, then make us think. We take a look at this year’s winners: from unboiled eggs to painful bee stings!

You can watch the award ceremony here.

The Chemistry prize was awarded to a team from Australia and the USA "for inventing a chemical recipe to partially un-boil an egg".

The Physics prize went to scientists from the USA and Taiwan "for testing the biological principle that nearly all mammals empty their bladders in about 21 seconds (plus or minus 13 seconds)".

The Literature prize was awarded to linguists from The Netherlands, USA, Belgium and Australia "for discovering that the word "[huh?" (or its equivalent) seems to exist in every human language — and for not being quite sure why".

The Management prize was given to three business school professors, "for discovering that many business leaders developed in childhood a fondness for risk-taking, when they experienced natural disasters (such as earthquakes, volcanic eruptions, tsunamis, and wildfires) that — for them — had no dire personal consequences".

The Economics prize went to the Bangkok Metropolitan Police, "for offering to pay policemen extra cash if the policemen refuse to take bribes".

The Medicine prize was awarded jointly to two groups, "for experiments to study the biomedical benefits or biomedical consequences of intense kissing (and other intimate, interpersonal activities)".

The Mathematics prize was given to Elisabeth Oberzaucher and Karl Grammer, "for trying to use mathematical techniques to determine whether and how Moulay Ismael the Bloodthirsty, the Sharifian Emperor of Morocco, managed, during the years from 1697 through 1727, to father 888 children".

The Biology prize was presented to scientists from Chile and the USA, "for observing that when you attach a weighted stick to the rear end of a chicken, the chicken then walks in a manner similar to that in which dinosaurs are thought to have walked".

The Diagnostic Medicine prize went to researchers from the University of Oxford and Stoke Mandeville Hospital, "for determining that acute appendicitis can be accurately diagnosed by the amount of pain evident when the patient is driven over speed bumps".

The Physiology and Entomology prize was jointly awarded to two individuals. Justin Schmidt got the gong "for painstakingly creating the Schmidt Sting Pain Index, which rates the relative pain people feel when stung by various insects". Michael L. Smith was granted the prize "for carefully arranging for honey bees to sting him repeatedly on 25 different locations on his body, to learn which locations are the least painful (the skull, middle toe tip, and upper arm) and which are the most painful (the nostril, upper lip, and penis shaft)".

Neurologist and acclaimed author Dr. Oliver Sacks died after complications with cancer at age 82. He was an extraordinary man who humanised the sufferers of mental disorders and introduced the general public to the world of neuroscience. Read his books. We highly recommend them!

Nobody is surprised, but we finally have good experimental data that shows a lack of sleep makes you more susceptible to illness. Less than 5 hours of sleep makes you four times more likely to get sick, and volunteers where locked in a hotel and given colds to prove it.

Climate change will cause many problems, but a new study potentially adds one more to the list: changes to nitrogen fixating bacteria that could dramatically effect nearly all sea life.

After its successful fly-by of Pluto, New Horizons has a new target: 2014 MU69. This 'cold classical' Kuiper belt object will be 43.4 AU from the sun when New Horizons arrives on January 1, 2019.

A new theory about our solar system's history proposes that there was a fifth giant planet early on that influenced Neptune's orbit and was flung out into interstellar space.

Two independent teams have manipulated a piece of viral protein so it can teach immune systems to fight whole groups of viruses, rather than a single strain. This could be the first step towards a universal flu vaccine and could eventually eradicate influenza altogether.

Over the last three years Professor Brian Nosek from the University of Virginia has managed to get a lot of psychologists from around the world to repeat 100 published psychology experiments. In a lot of cases, the new results were considerably different from the original experiment's results.

A psychologist in Italy got study participants to stare into each other's eyes for ten minutes and describe what they felt. Weird things happened!

Dr. Miranda Ween is investigating the potential health effects of e-cigarettes.

Nasa has awarded a $200,000 per year grant to researchers to investigate ways to turn poop into food.

Scientists at the American Fisheries Society annual meeting have called for changes to how decisions are made in fisheries. Unprecedented conditions like the North Pacific blob demonstrate a need for ecosystem-based modelling instead of the more common species-based modelling.

Can smelling vomit make you sick? The answer is yes, but to prove it virologists had to build a machine that vomits.

Dr. Krystal is now working at the BioMelbourne Network, the peak industry body for life sciences in Melbourne, Australia.

In an important step forward for human space exploration, astronauts on the ISS have eaten lettuce grown on the station. They liked it.

Despite having only a 36% success rate, the new malaria vaccine called 'Mosquirix' has been endorsed for young African children. The hope is that the vaccine, when combined with other existing defenses, can still greatly reduce the incidence of severe malaria.

New research studying almost 20,000 galaxies in one small section of the sky shows the universe has long passed its peak and is slowly dying. Which is a gloomy way of saying that the rate of new stars being born is decreasing.

We all know that no vaccine is ever truly 100% effective, yet that's exactly what early stages of a new Ebola vaccine seems to suggest.

The humble octopus has an exceptionally complicated genome, which goes part way to explaining the complexity of these incredible sea creatures.

In 2011 a tornado ripped through Joplin, Missouri, killing 158 people. It also brought with it a rare flesh-eating fungus that killed another five.

The first two species of 'venomous' frogs have been discovered - the hard way - in the Caatinga forests of Brazil. And you really don't want them to headbutt you.

There's a parasitic wasp that uses mind control on spiders to force them to spin cocoons. Because nature is like that.

We mention this David Attenborough video about the Cordyceps fungi that zombifies ants.

We also mention spider webs produced by spiders on drugs.

Shayne recommends the XKCD webcomic about the bee orchid.

Ed recommends watching Ed Yong's TED talk about mind controlling parasites.

Simon Chapman is Professor in Public Health at the University of Sydney, and was called upon to give evidence before the Select Committee on Wind Turbines. They asked his opinion, and he well and truly delivered it!

A special episode all about Pluto and the New Horizons mission. We're joined by Dr. Mike Goldsmith, a science writer with a PhD in astrophysics who's currently writing a book about Pluto. Keep an eye on Amazon for New Horizons To Pluto to be published in the next month or so.

A growing body of research suggests that males and females process pain differently. It also opens promising new fields of further study.

A single-celled organism has no brain and no nervous system, so you wouldn't think it could have an eye. But the dinoflagellate Erythropsidinium is able to "see" polarised light, and aim its piston accordingly.

The iconic 3D holographic computer interfaces from the Iron Man movies and Minority Report might be not far off, as researchers in Japan have developed a way to suspend light in mid-air and make it safe to interact with.

Approximately 2.1 billion years ago saw the emergence of multicellular organisms. New research suggests that the leap from single-celled life to multicellular creatures may have been fairly simple, and there may have been more than one way it happened.

Researchers at the University of Bristol have developed a system for self-healing aeroplane wings. The material, which uses a liquid carbon-based "healing agent" could also be used for bicycle frames and wind turbines.
