What I worry about is the lack of understanding in society around the world that there is a divide in the world between those who have and those who do not.

I have a charity called the Chain Of Hope, where we target children from poor areas where heart surgery is not available, and we offer our services.

The nanofibrillar scaffolds designed to guide the process of cellular repopulation is an important step towards prolonging life and enhancing the quality of life for patients with advanced heart disease with defective valve.

I actually consider myself as totally privileged to be able to serve science and medicine in a global fashion, because science and medicine know no boundaries.

My own writing has perhaps more of an American flavor than a British one, but that's because the stories I've so far written have needed it. 'Empire State,' 'Seven Wonders' and 'The Age Atomic' are all very place-centric, where the setting itself is almost a character. But there is a universality to story that isn't just limited to science fiction.

Neuroscience is a baby science, a mere century old, and our scientific understanding of the brain is nowhere near where we'd like it to be. We know more about the moons of Jupiter than what is inside of our skulls.

The science is clear that there is an increase in the amount of CO2 in the atmosphere. What is not clear from the science is how much of that increase is caused by human activity; and what also is not clear is what impact those increases have on the climatic cycle.

Further, the dignity of the science itself seems to require that every possible means be explored for the solution of a problem so elegant and so celebrated.
