Perceived lapses in the peer-review process often receive a lot of attention, but the majority of researchers declare themselves satisfied with the system. But if it is broken, how do we fix it?

The air pressure increases because more air particles are being added to the inside of the tyre. Pressure is caused by gas or liquid particles colliding with the walls of a container. Think of a ...

When soda companies add carbon dioxide gas to a soda mixture, the water is very cold so it can hold a lot of gas. They also use pressure to put more gas in the water than it could normally hold at ...

Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.

High-pressure pump–probe experiments reveal the mechanism of excited-state proton-coupled electron transfer and a shift from stepwise to concerted pathways, Nature Chemistry (2025). DOI ...

The researchers who developed the process say the unusual materials could have applications in industrial chemistry ... then crushed it at an enormous pressure of up to 200 megapascals.
