What is it that makes us feel drunk when we drink? And why do we keep drinking if it can make us feel so terrible?
Put simply, it's the outcome of a chemical reaction, which humans learned how to make some 400,000 years ago.
Even a small cloud can weigh as much as four tonnes – but gravity, chemistry and temperature keep them floating in the sky.
Artist’s rendering of a Mars artificial gravity transfer vehicle.

Subbing new risks for the current dyes’ dangers?
Less-toxic hair dye would be a great invention. But discounting the risks that come with nanoparticles could undermine other efforts to protect human health and environmental from their effects.
There are nanometals in your washing machine.
Many socks, towels and other textiles are treated with silver nanoparticles to kill germs and odors. When the silver washes out, it can pollute waterways. Two chemists propose a way to collect it from wastewater.
