A weekly show where we endeavor to answer one of your big questions. This week, Sarah F. asks, "Can you really be tired from sleeping too much?"

Gold is seen as a valuable metal world wide. Where did this idea originate and how much is it worth today?

A lot of things can kill you - but here are some surprising ones!

The presentation was made at the Hawking Radiation conference, which was co-hosted by the theoretical physics institute, Nordita, and the University of North Carolina, on the campus of KTH Royal Institute of Technology in Stockholm. Nordita is driven by both KTH and Stockholm University.

Scientists have used a high-speed camera to film hummingbirds' aerial acrobatics at 1000 frames per second. They can see, frame by frame, how neither wind nor rain stop these tiniest of birds from fueling up.

Bacon bacon bacon bacon bacon!

What is dark energy? What is dark matter? Well, if we knew exactly we would have a nobel prize - we know that they exist though. So what do we know about those strange things?

Holy moly I'm gonna tear my $100 bill into five and rearrange it and boom! I have $200.

Man and woman's best friend!

What was the procedure to launch a nuclear missile?

Will the crow defeat the puzzle?

What would happen to you if a black hole the size of a coin suddenly appeared in your pocket? Lets find out!

Uranium is a unique element, used in research, medicine, space travel, and of course weapons.

Turn water into wine! This simple science experiment demonstrates how fluids with different density can switch places. Fun to use as a magic party trick or as a demonstration for a physics experiment. Watch as the water switches place with the wine, because water has a higher density then wine. You could try using a playing card instead of the thin plastic spacer.

We use a LOT of energy, but we waste a lot too. Where that waste happens might surprise, you though. We don't just waste energy when we leave the lights on or the thermostat cranked down too low. It happens at the dinner table and the water faucet as too!

Why do spikes form on ice cubes? Without them the world would be vastly different.

It's definitely higher than "11"

The world of energy is a confusing place. What's better, nuclear or solar? What's the difference between fluorescent bulbs and LEDs? What's the difference between energy and power? And what the heck is a kilowatt-hour?!

Is the science of Orphan Black realistic? Could we clone humans, or engineer them to have customized traits? We take a look at today's genetic engineering technologies to find out if designer babies and human cloning is, or should be, a reality.

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.
