The media need superheroes in science just as in every sphere of life, but there is really a continuous range of abilities with no clear dividing line.
In Britain, like most of the developed world, stem-cell research is regarded as a great opportunity. America will be left behind if it doesn't change policy.
I would like nuclear fusion to become a practical power source. It would provide an inexhaustible supply of energy, without pollution or global warming.
The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?
I think the brain is essentially a computer and consciousness is like a computer program. It will cease to run when the computer is turned off. Theoretically, it could be re-created on a neural network, but that would be very difficult, as it would require all one's memories.
We think we have solved the mystery of creation. Maybe we should patent the universe and charge everyone royalties for their existence.
Science predicts that many different kinds of universe will be spontaneously created out of nothing. It is a matter of chance which we are in.
It is generally recognised that women are better than men at languages, personal relations and multi-tasking, but less good at map-reading and spatial awareness. It is therefore not unreasonable to suppose that women might be less good at mathematics and physics.
We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet.
