Thousands of chemical compounds in wildfire smoke are interacting with each other and sunlight as the smoke travels. For people downwind, it can become more toxic over time.
Sensors are everywhere, from your phone to your medicine cabinet. Here's how they turn events in the physical world into words and numbers.
New research suggests ordering the elements by atomic radius and ability to attract electrons.
Our research marks the first case of both normal diamonds, as well as Londaleite, being produced in a lab setting using only intense pressure.
Batteries power much of modern life, from electric and hybrid cars to computers, medical devices and cellphones. But unless they're made easier and cheaper to recycle, a battery waste crisis looms.
An optical sensor that can detect individual molecules promises early detection of diseases and environmental contamination.
What do ammonium nitrate and iodine have in common? Both substances are of immense service to humankind, and the history of their discovery is closely linked to that of the production of explosives.
Jennifer Doudna and Emmanuelle Charpentier have been awarded the Nobel prize in Chemistry for their revolutionary work on 'gene scissors' that can edit DNA.
Emmanuelle Charpentier and Jennifer Doudna share the Nobel prize for chemistry for their CRISPR/Cas9 tool to rewrite the blueprint of life.
You might think the more oxygen you breathe in the better. But too much oxygen can make you sick.
Considering what we know about the key ingredients for life's formation on Earth, here are three explanations for how this process may have occurred on our sister planet.
Halide perovskites are cheap, versatile and remarkably efficient as both solar cells and light emitters.
Bricks turn out to be useful for storing electricity thanks to their porousness and red pigment.
For combustion to occur, oxygen must be present. Ammonium nitrate prills provide a much more concentrated supply of oxygen than the air around us.
EVs will have lower sticker prices than gas vehicles when batteries are cheaper. Getting there comes down to knowing where to cut costs.
A history of the drug crystal meth.
Pepper spray uses a chemical called capsaicin. It's the same compound that makes chillies hot, but in a more intense, weaponised form.
The chemical weapon, tear gas, was used in Washington DC, Los Angeles, Orlando and several other cities to control crowds protesting the death of George Floyd. But what is it? Does it cause harm?
New manufacturing processes will revolutionise the way we take our medicines.
