It consists of two main parts–a liquid outer core and a more solid inner core. The outer layer is made of liquid iron-nickel and is responsible for producing Earth’s magnetic field.

Earth’s innermost layer is a hot, solid ball of metal surrounded by a liquid metal outer core. For decades, planetary scientists suspected that the solid inner core deformed over time as it spun.

(Edward Sotelo/USC) Earth's solid inner core represents one of the most mysterious engines in geophysics. It's rotating around down there, wrapped in a cushioning shell of molten outer core, ...

The inner core spins independently from the liquid outer core and from the rest of the planet. Without this motion, Earth would die and become more like barren Mars which lost its magnetic field ...

Ear cancer is when abnormal cells in the ear start to grow and divide in an uncontrolled way. Most of these cancers start in the skin of the outer ear. Cancers that develop inside the ear, known as ...

Late last month, before the rains arrived, USC professor Seth John traveled through foothill neighborhoods devastated by the Eaton Fire, gathering street dust to test for lead. Another USC ...

Planets originate from protoplanetary disks, circulating disks of gas and dust that develop around young stars, a recent study revealed. ALMA observations of the protoplanetary disk around HD 142527.

Capturing and predicting such extreme events is critical for society. The Lagrangian particle dispersion model FLEXPART and the associated dust emission model FLEXDUST have been recently developed and ...

Snapshots of colorful galaxies and planets show that the beauty of our universe knows no bounds, and recent images of glowing space gas and dust captured by NASA are no exception. The James Webb Space ...

Dusting more than usual these days? On top of the other never-ending chore list of sweeping, mopping, laundry, and all else, no one wants to spend more time than they should swiping up unsightly dust.

An inner-thigh rash may be caused by a variety of factors, including friction, chafing, an allergic reaction, a disease, and a health condition. Its appearance depends on the rash's trigger. The ...
