Shifting sands, creeping soils, and a new understanding of landscape evolution

New experiments show that, even when undisturbed, piles of sand grains are in constant motion, challenging theories of how soils and other types of disordered materials behave.

Connecting a star’s chemical composition and planet formation

Along with developing a new statistical method for studying exoplanets, researchers from Penn found that the majority of stars in their dataset are similar to the sun, implying that many stars in the Milky Way could host their own Earthlike planets.

Dark Energy Survey interim analysis sheds light on the evolution of the universe

Analysis of the survey’s first three years of data, which were used to make the most precise 3D map of the universe to date, is a key step towards understanding dark matter and dark energy.

Insights into new ‘dials’ for controlling a material’s magnetism

New research demonstrates how small amounts of strain can be used to control a material’s properties, with possible applications ranging from spintronic devices to faster hard drives.

Beyond topological insulators

Charlie Kane and Eugene Mele’s groundbreaking theories on the existence of a new class of materials continues to inspire an upcoming generation of physics researchers.

27 million galaxy morphologies quantified and cataloged with the help of machine learning

Using data from the Dark Energy Survey, researchers from the Department of Physics & Astronomy produced the largest catalog of galaxy morphology classifications to date.
