Order to disorder: a closer look at icy surfaces
Much like a tongue freezes to a frigid metal pole, ice can cause speed up the adsorption, or stickiness, of molecules. An icy surface can also cause molecules to degrade in the presence of light, releasing trace gases. Before researchers can measure these reactions and incorporate their impacts in global atmospheric models, researchers first need to understand the…

Quantum computers successfully model particle scattering
Scattering takes place across the universe at large and miniscule scales. Billiard balls clank off each other in bars, the nuclei of atoms collide to power the stars and create heavy elements, and even sound waves deviate from their original trajectory when they hit particles in the air. Understanding such scattering can lead to discoveries about the forces that govern the…
