Download the experiment instructions HERE! Let’s learn about the properties of liquids and solids: Solids are not compressible, they’re rigid, they don’t flow, and their particles are packed close ...

For more than a century, schoolbook physics has divided matter into neat categories like solid, liquid, gas, and plasma. A wave of recent experiments is now tearing at those boundaries, revealing ...

Scientists now understand why seismic waves speed up near Earth's core. Extreme pressure and temperature cause solid mantle rock to flow slowly, aligning mineral crystals. This anisotropic structure ...

Though Earth's innermost core is solid, new research suggests that it hosts a lot of variation. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

A new state of matter appears to be a solid-liquid hybrid, scientists from Ulm University in Germany and the University of Nottingham in the UK have reported in the journal ACS Nano. The newfound ...
