Scientists have discovered a new brain glitch that is the exact opposite of deja vu. While deja vu is the unsettling sense that you've lived a moment before, jamais vu is when something familiar suddenly feels alien -- like encountering it for the very first time. You've likely felt it: walking through your hometown and suddenly feeling lost, or repeating a common word until it sounds strange and meaningless. Repetition is often the trigger. The brain, overloaded by familiarity, short-circuits, making the ordinary feel bizarre.

Keeping count of nostril hairs and investigating the promiscuity of anchovies may seem completely unrelated. But these studies are among 10 others to win this year's spoof'Ig Nobels', thanks to their ability to make scientists chuckle. Traditionally hosted at Harvard University, this ceremony is the 33rd of its kind, and sees genuine Nobel laureates handing out awards to lucky academics. The prize is ten trillion Zimbabwean dollars, which might sound like a huge amount, but is actually only the equivalent of 30p in the UK (40 cents in the US). MailOnline spoke with some of the wackiest prize winners of 2023.
