Chemists win Nobel Prize for faster, cleaner way of making molecules
Both scientists independently came up with new process — asymmetric organocatalysis. That name may be a mouthful, but it’s not that hard to understand.

Explainer: In chemistry, what does it mean to be organic?
These are molecules formed by combining carbon with other elements, especially hydrogen.
- Physics
Scientists Say: Plasma
In physics, plasma refers to one of the four states of matter. In medicine, plasma describes the part of blood that ferries cells, nutrients and more throughout the body.

Scientists Say: Aerosol
Aerosols are tiny bits of solids or drops of liquids suspended in gas. Aerosols include mist, fog and soot, as well as pollution from fossil fuels.
- Chemistry
Scientists Say: Oxidation and Reduction
Oxidation and reduction are two parts of a chemical process in which one atom steals electrons from another.

Explainer: What is an electrode?
An electrode’s name depends on the circumstances. Confused? It may help to consider which electrochemical reaction is natural — and which is not.

Explainer: Ions and radicals in our world
When atoms get an electric charge, they act very differently. Now called ions, these are behind many aspects of chemistry, including acids and batteries.

New glue offers to turn any small walking robot into Spider-Man
To climb walls, robot feet need to alternately stick and let go. A novel adhesive can do that. Its stickiness is controlled by electric fields.

Lots of makeup may contain potentially harmful ‘forever chemicals’
Hints of PFAS compounds have turned up in about half of tested makeup products. Waterproof mascaras and lipsticks were very likely to contain them.

Father-son bond inspires sweets that model the shapes of molecules
These bite-sized gummy candies could spark interest in the world of chemistry, especially among students who can’t see.

Sleep-friendlier lighting is on the way
Chemists have created a new glowing material for LEDs. It should lessen how much near-bedtime lighting impairs your ability to nod off.

Scientists Say: Bond
In chemistry, this attachment between atoms forms because of the power of attraction. Chemical bonds make up every solid object on Earth.
