You might have felt it -- the feeling that you've experienced something before, but, in reality, the experience is brand new. There are over 40 theories that attempt to explain the phenomenon of deja vu.

What is the specious present? And how do our brains perceive time?

It's 4am, and the big test is in 8 hours. You've been studying for days, but you still don't feel ready. Should you drink another cup of coffee and spend the next few hours cramming?

His talk was given at a local TEDx event, produced independently of the TED Conferences. "The earth is flat". "Home computers are useless". "Humanity is condemned to be starved". "Women are born inferior". Throughout the years, pioneering scientific discoveries overturn established theories, vibrant societies transcend dominant perceptions, bold individuals expand physical and intellectual limits proving everything wrong: This is the way in which we seek to improve our lives and to deepen the understanding of the world around us. At TEDxLimassol we are searching for the next refute in small and large things: In the universe and subatomic particles. In our societies and in our bodies. In our behavior, attitudes and perceptions. In our mental, physical and personal capabilities. Proving everything wrong is always the right thing to do.

Have you ever wished you could record your dreams and watch them later? It may be possible sooner than you think...

*Yaaawwwwwn* Did just reading the word make you feel like yawning yourself? Known as contagious yawning, the reasons behind this phenomenon have been attributed to both the physiological and psychological. It's been observed in children as young as four and even in dogs! Claudia Aguirre visits the many intriguing theories that might explain contagious yawning.

A weekly show where we endeavor to answer one of your big questions. This week, Emma R. asks, "Why do I get that weird ringing noise in my ears?"

Most of us have felt it before, that strange sensation that you've been somewhere or seen something before, as if you already remembered what's happening. Are you psychic? Nope, that's just deja vu. Why does deja vu happen? Well, scientists aren't completely sure, but they've got a few good theories about it.

This week, Jen Alexander asks, "Do your organs grow with you?"

Our bodies do a lot of weird things, and many of them are completely involuntary. Why do we often jerk our bodies awake right before falling asleep? Why do we yawn, or hiccup? Why do some people sneeze when they look at the sun? And why does your eye twitch? This week we'll look at the science behind these crazy involuntary behaviors!

Heart racing, palms sweating, labored breathing? No, you're not having a heart attack -- it's stage fright! If speaking in public makes you feel like you're fighting for your life, you're not alone. But the better you understand your body's reaction, the more likely you are to overcome it. Mikael Cho advises how to trick your brain and steal the show.

Dyslexia affects up to 1 in 5 people, but the experience of dyslexia isn't always the same. This difficulty in processing language exists along a spectrum -- one that doesn't necessarily fit with labels like "normal" and "defective."

Have you ever wondered why the brain is located where it is?

Why does music make us feel happy or sad? Or angry or romantic? How can simple sound waves cause so much emotion? I went from my comfy chair to the streets of Austin to investigate how it might be written into our neuroscience and evolution. Modern neuroscience says our brains may be wired to pick certain emotions out of music because they remind us of how people move!
