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.
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.
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.
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.
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.
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.
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.
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.
Medicinal chemists are tweaking a natural molecule that can be a deadly poison – a modified version might work as a nonhormonal male contraceptive.
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 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.
Remembering J. M. Creeth, 70 years after he discovered hydrogen bonds in DNA.
