The psychology behind self driving cars: What happens when people don’t interact with technology in the way that developers expect?

These animal mating rituals reveal some secrets of our own Valentines Day behavior. And after the video, crawl on over to PBS NATURE and check out Spy in the Wild!

When illness goes viral, Munchausen by Internet may be the symptom.

Our reaction to be tickled may be nature's way of encouraging self defence training from an early age.

Your sense of smell is incredible. Inside your nose, odour molecules interact with your senses at the quantum level – you can detect the presence of extra neutrons in a molecule. Lots of the ways we experience the world are on the teeniest, tiniest scale. It's just one of the places that quantum mechanics interacts with biology. Now you nose

Your brain does its best to piece together the world – but our senses are susceptible to being tricked. For centuries we thought that optical illusions only tricked our visual perception – now we know that the same illusions can trick the touch perception of those who are blind. There’s more to the humble optical illusion than first meets the eye

Even those that are most productive in their lives are known to take a “breather” from the chores and obligations and just let their mind wander. Taking a break to do simple or "mindless" tasks can have a positive impact on your creativity, productivity and decision making. So if you're going to procrastinate or waste time, here's how to do it properly. And it involves one of our most favorite platforms - YouTube! There are ways you can effectively waste time that can lead to a boost in problem-solving, productivity and creativity. Researchers at the University of Melbourne have published a number of studies on “workplace internet leisure browsing”. We have to say, we are experts at workplace internet leisure browsing! In one of said studies, researchers have said that those who “surf the internet for fun at work” within a reasonable time limit, say, less than 20% of their total time in the office, are 9% more productive than those who stay clear of these activities. In the follow-up studies, researchers argue that workplace internet leisure browsing is “an unobtrusive interruption which enables restoration of mental capacity and fosters feels of autonomy”. A study titled “Inspired by Distraction: Mind Wandering Facilitates Creative Incubation” from the University of California, found that when participants did an undemanding task, it led to substantial improvement in performance on a problem they’ve encountered before, compared to those doing a demanding task, just resting or having no break at all. The conclusion is that letting the mind to wander by doing simple tasks can boost creative problem-solving.

It is equally as effective.

How do makeup and our perception of beauty affect our trustworthy and credible we appear? The 100 layer challenge, with science.

Some perspectives on wisdom, from both psychological research and my Nana. It turns out that both reveal it's much more nuanced than saying "older people are wiser" – there are different types of wisdom, wisdom is positively correlated with personality traits and wisdom can even be learned.

If you're feeling lost about what happens inside a VR headset, you can count on your brain's’ internal GPS to guide you through virtual reality experiences. Here, we dive head(set) first into the neuroscience and psychology of VR.

This sleep cycle is a good average: your circadian rhythm can shift somewhat depending on your sleep/wake schedule. If you wake consistently at 9am, then your blood pressure with go up closer to 8:45am and everything else will be shifted as well. It's tied to sunlight A LOT but since we have artificial light, there's wiggle room within that.

How can we figure out the intelligence of something that's been extinct for millions of years? Well, one way is by looking at the structure of its brain. I chat about what we know about dinosaur brains with my friend Dustin Growick, dinosaur whisperer. I also dissect a T. rex brain, which really means I cut up a clay model with a knife. It was fun.

Using our cells to develop new treatments or medicines saves millions of lives. But, should you own the rights to your biological material? And should you consent to your cells being used in research?

Are you a morning person or a night owl? I've never been an early bird – and lately I've been wondering why. This pattern in your sleep/wake cycle is called your "chronotype" and appears to be influenced by your genetics. It has some interesting effects on your health – from some people being more agreeable and proactive to others eating and drinking more. Do you notice an effect on your health?

A lot of us can stop and visualise things in a flash – a rainbow, your breakfast table, your Mum's 80s haircut. But "visualising" isn't the norm for everyone – some people don't imagine things in a visual way. While our "mind's eye" allows a lot of us to see things in our head, other people imagine with words or concepts – in non-visual ways.

The Allais Paradox undermines the theory of expected utility because it shows that we don't always make decisions that align with our wants and needs. So, would you prefer a higher chance of living, or a longer life? And then, which pills did you choose?

How do you hear your inner voice? You know, that little person in your head... wait, is there a voice in YOUR head? Do YOU have an inner voice at all?

The Cocktail Party Effect is an auditory phenomena that, really, humans shouldn't have to solve – normally we can automatically separate different sounds and voices through our selective attention. But it's hard, right? Well Artificial Intelligence found it even harder – a machine found it difficult to determine the difference between audio tracks.

We explore Misophonia, a sound sensitivity syndrome where people have strong emotional reactions to common sounds. We meet Vanessa's friend Molly Templeton and clinical psychologist Dr. Ali Mattu to talk about the brain basis of Misophonia, trigger sounds, reactions and treatment.
