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.

Louise Brown's birth marked the end of the beginning of human IVF, acclaimed at the Royal College of Obstetricians and Gynaecologists. This event was snubbed by some clinicians now styled as 'pioneers', who shouted that the test-tube claim was a fake! They did not matter.

What I have tried to show is that the scientific attitude implies what I call the postulate of objectivity - that is to say, the fundamental postulate that there is no plan, that there is no intention in the universe.

I think it started since I was born, I always had a need to express myself, you know, as a human being, and I found that it felt right when I expressed myself through art, dance, through acting, so it kind of happened naturally.

People like space. But they sometimes have been left out. People are much more open to that if you invite them in.
