You may well have experienced motion sickness or travel sickness in the past. Well, cyber sickness is a modern ailment that follows a similar kind of logic, or rather the opposite logic. Instead of moving while feeling still, like when you’re on a boat or in a car, with cyber sickness you perceive movement while you’re actually still. But the result is the same: your brain fails to adapt to this d...

But all too often it’s used as a weapon to...

The concept of the narcissistic pervert has invaded our screens and magazines in recent years. It's used a lot, but sometimes wrongly or without full understanding. So what is it really about?

No doubt you’ve heard at some point in your life that girls are more mature than boys. As a result, we tend to forgive childlike behaviour in men more easily, even in adulthood.

You may remember that we discussed the topic in...

Right from primary school age, we tell children that if another boy or girl has teased them, it’s “because they like them”. And playful teasing happens a lot in dating well into adulthood.

Warm summer nights often bring unwelcome guests into our homes in the form of mosquitoes. For now we fortunately don’t have any mosquito-borne diseases being transmitted to humans in the UK, but with the warmer temperatures brought on by climate change, it may only be a matter of time until that changes.

Have you ever wondered how our expectations can impact the way we perceive and interact with others?

Back in 2015, 10,000 participants at Newcastle University’s Numbers Festival were asked what their favourite number was. Perhaps unsurprisingly, 12.6% of them answered the number seven, making it the most popular number of them all.
