Could smashing atoms with giant accelerators be the wrong way to understand the nature of time? Some think we should just give atoms a little push...like a curling stone!

Geneticist Robert Lanza brings extinct animals back to life, and says the technology exists to bring back dead humans. But will society ever permit human cloning?

Cosmic dust and other matter cloud our view into space. So scientists have not technically seen a black hole. But one astronomer claims he has seen past the cosmic litter using a new infrared technology. And according to him, he saw a massive bla ...

Canine psychologist Stanley Coren has measured the intelligence of more than 100 dog breeds. Find out how doggie smarts are measured and see which breed is ranked seventh from the bottom!

In the first moments of the universe, unstable matter and particles were born and then vanished in fractions of a second, ultimately evolving into matter as we know it today. Can scientists recreate those first moments?

Computational neuroscientist Yuki Kamitani explains how a computer can visualize what a person is seeing, just by monitoring their brain. In a few years, we may be able to watch our own dreams in HD!

What if the beginning of our universe was not really the beginning of all existence? One scientist believes time has always existed. The death of another universe may have led to the beginning of ours.

Massively sophisticated computer networks are capable of simulating the start of the galaxy. People just need to input the right variables to make it work. How does dark matter change the results?

Alien evolution could produce a living machine-like planet filled with the intelligence of billions of alien minds. But if this does exist, how do we spot it?

If there are aliens, they could see that our planet supports life from the variety of colors produced by land, water and weather on Earth. However, we don't yet have the proper tools to identify colors of faraway exoplanets.

If backwards time travel was possible, could we change history? Or is the power of space and time so great that time travelers would be unable to alter even the smallest detail?

Can the creation of life be understood by looking at bubbles? One scientist may have finally created the first cells of life under his microscope.

When we adapt a memory to match those of our peers, do we also change a signal in our brain that creates a false memory?

Supermassive black holes are classified as possessing a total mass between one million to one billion times the mass of our sun. That's huge!

Physicist Lee Smolin applies the theory of evolution to physics to help explain how the laws of nature came to be.

A scientist creates hair-raising experimental short films to find out how empathy works in the human brain.
