Laser are used in some many things around us from computer storage, discs, communication, medical scanning and even laser surgery. Turning lasers from an expensive tool in the exclusive hands of large laboratories to something people all over the world can simply and easily use required groundbreaking physics. As did turning a laser into a pair of precise tweezers. For that groundbreaking research Arthur Ashkin, Gerad Morou and Donna Strickland won the Nobel Prize in physics in 2018. We find out about lasers, how they're used and how they were made powerful and precise.

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?
