Sunlight + gold = steaming water (no boiling needed)
Nano-gold is the new black, at least when it comes to absorbing heat. When tiny gold particles get together, they become energy super-absorbers — turning them black.

Genes: How few needed for life?
Scientists rebuilt a microbe using its old genes. But not all of them. They used as few building-blocks as they could get away with and still have the life-form survive.
