From HAL and "Speak & Spell" to Siri, and Alexa, we look at how speech synthesizers work... and why they still don't work perfectly!

Is there still a place for the lone genius inventor - the Edison, Ford, Tesla, or Marconi? Or is invention now solely the province of giant corporations like Apple, IBM, and DuPont?

Hurrah, the Olympics is nearly here! From springy pole vaulters and leaping long jumpers to spinning ice skaters and slippery swimmers, we're going to take a quick tour through the surprising science behind sport!

Let's zip back over two and half thousand years to understand the sparky story of electricity, from Thales and Aristotle to Edison, Marconi, and James Clerk Maxwell!

How goes a gecko stick to the ceiling... why doesn't glue stick to the tube? Today, I'm exploring adhesive and cohesive forces and trying not to come unstuck as I explore the sticky science of glues.

Can you feel the force? Maybe it's gravity - the tingling attraction between everything in the Universe and everything else. Where does it come from? What causes it? How near are we to understanding it?

From anatomy to abnormality, we compare nature's finest marvel (the human brain) with the best that humans have so far produced (the electronic computer). How are they similar and how are they different? Is the Net becoming increasingly brain-like? Will it ever become conscious and self-aware?

Nuclear power plants make about 10 percent of the world's energy by splitting atoms apart, but they have a very mixed history. So what about nuclear fusion, a better kind of nuclear power, that joins atoms together? We explain how it works... and look at whether it can deliver enough power to solve the energy crisis and climate change.
