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.

It is possible to split water into oxygen and hydrogen gas in zero gravity using sunlight, shows new study.
US firm HeatGenie is hoping to revive a technology that has surprising origins in World War II and beyond.
The world's biggest diamond company is to sell synthetic gemstones for the first time.
It’s been 70 years of instant photography, thanks to Edwin Land, on the left.
Whether at a family gathering or in a research lab, getting access to images immediately was a game changer. And Land's innovations went far beyond the instant photo.
Sugar mama? Researchers are teasing out the benefits of various molecules in human milk.
A chemist explains how some molecules in human breast milk help fight infection. Understanding their properties could lead to better infant formulas that share the health advantages of breastfeeding.
The warming of the outside of the ice cube happens faster than the warming of the inside, causing it to crack.
Mai Lam/The Conversation NY-BD-CC
Water is one of very few chemicals that is found as a liquid, solid and gas at any time on Earth. These three states of water help explain why ice makes a cracking sound when water is poured over it.
That pre-sleep herbal tea may be doing many people a lot of good.
Adding lemon makes your tea taste nice - and changes its colour.
It's all about the chemistry. Adding lemon can enhance the flavour and enjoyment of tea, and change its colour, but its best not to expect any extra boosts to your health.
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.
Hundreds of people have been warned after former Russian spy Sergei Skripal was poisoned with Novichok nerve agent.
Through abstraction, the underlying essence of a mathematical concept can be extracted.
High-tech ways to scan nature’s own creations.
Pharmaceutical companies focus on small molecules they've devised – and can easily patent. But nature's already come up with many antibacterial compounds that drug designers could use to make medicines.
Will blue packets replace pink ones soon?
Medicinal chemists are tweaking a natural molecule that can be a deadly poison – a modified version might work as a nonhormonal male contraceptive.
The comet 67P/Churyumov-Gerasimenko, seen up close.
Dust can be instructive. The analysis of those collected around the comet 67P/Churyumov-Gerasimenko provided new information on the history of the solar system.
The ingredients of incense were detailed in the Old Testament.
The four ingredients for holy incense are listed in the Old Testament, but there was much debate over the origin of one of them -- onycha. Scientists think they've now confirmed the source.
