A quirky material that behaves like a mishmash of liquid and solid could be hidden deep in the Earth. Computer simulations described in two studies suggest that the material in Earth’s inner core, ...

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 ...

The Earth’s inner core is incredibly tricky to study, since it’s buried beneath thousands of miles of rock. New seismic studies suggest that it’s not just a solid ball of iron, as has been assumed, ...

A strange type of ice thought to dwell deep in the oceans of alien planets has finally been proven to exist. For the first time, researchers have directly observed a sort of hybrid phase of water ...

People who investigate scientific topics either love or hate glass, which is a confusing none-of-the-above unicorn: neither fully liquid nor fully solid, exhibiting some properties of each, but ...

Researchers have detailed the physics behind a phenomenon that allows them to create spin in liquid droplets using ultrasound waves, which concentrates solid particles suspended in the liquid. The ...
