Can a single fly ruin a drink? How long does the fly even need to be in there to destroy the quality and taste? How does a fly even manage to ruin your sense of taste? These important questions were answered by the winners of the Ignobel Prize 2018 in Biology.
Does having a more expensive label on something make it feel 'better' to eat, drink or use? What's going on in our brain when the "Label Placebo" effect takes hold? If you're an expert are you more easily swayed by the placebo than a regular person?

It's Ignobel Prize 2018 time. As part of Improbable Research's celebration of curious and comedic science, we find out the rollercoasters, and how they are just what the doctor ordered. The Ignobel Prize 2018 in Medicine went to Mitchel and Wartinger for their ground breaking work into how to use rollercoasters to treat Kidney stones. We look into how rollercoasters work, their impact on the body, and how it can help pass kidney stones. Plus we look at some research into how rollercoaster g-force can impact your brain.

Concussions are a serious issue for everyone from the largest professional leagues to the weekend amateurs. The CDC has released some updated guidelines for assessing concussions and we dive into some new tests to help take the decision out of players hands and back it up with some sound evidence.

Exoplanets are home to some extremely out of this world chemistry. From raining diamonds, to gaseous iron and titanium, even to secret supplies of water. If we want to understand just how unique our place in the universe is, we can try and replicate the odd conditions of exoplanets right here on earth.
