Scientists Say: Proton
These positively charged particles are important building blocks in atoms.
- Chemistry
Simple process destroys toxic and widespread ‘forever’ pollutants
Ultraviolet light, sulfite and iodide break down these PFAS molecules faster and more thoroughly than other methods.

New cloth cools you when you’re hot, warms you when you’re cold
Scientists 3-D printed the new fabric, which has even more tricks up its sleeve — such as conducting electricity and resisting radio waves.
- Chemistry
New process can transform urban CO2 pollution into a resource
Researchers have developed a liquid metal that breaks down carbon dioxide in the air, converting it from a climate threat into a valuable raw material.
