Cancer is really a DNA disease... We have these certain genes that prevent our cells from growing out of control at the expense of the body. And it's a pretty good, robust system. But if a couple of these genes fail, then that's when cancer starts, and cells start growing out of control.

We really should be grateful to the people who participate in research and allow certain details to be published about themselves. Because if they didn't, we wouldn't have nearly the understanding of the brain that we do.

Some scientists claim - although these claims are contentious - that they can form deadly isomers with simple X-rays and that hafnium can multiply the power of these X-rays to an astounding degree, converting them into gamma rays up to 250 times more potent than the X-rays.

Except for certain moments - when cells are dividing, for instance - chromosomes don't form compact, countable bodies inside cells. Instead, they unravel and flop about, which makes counting chromosomes a bit like counting strands of ramen in a bowl.

Although there is a very large literature, still growing almost daily, on the Chinese calendar, its interest is, we suggest, much more archaeological and historical than scientific.

I don't think Brian Cox does 'The Wonders of the Solar System' because he believes the world would be a better place if people understood about the rings of Saturn; I just think he finds physics extremely interesting. It brings him joy, and he wants to spread the love. I feel the same about economics.

I think I've kind of carved out a sweet spot for myself by combining science and comedy.

It is not so for art in appreciation because art is concerned with human behavior. And science is concerned with the behavior of metal or energy. It depends on what the fashion is. Now today it's energy. It's the same soul behind it. The same soul, you see.
