Research elucidates why protons are at the heart of atoms spin

A major new finding about the fundamental structure of all matter has just been published. The research stems from an analysis of data produced by an experiment in polarized proton-proton collisions.

Dynamic hydrogel used to make 'soft robot' components and LEGO-like building blocks

A new type of hydrogel material could soon make assembling complex microfluidic or soft robotic devices as simple as putting together a LEGO set.

Engineers demonstrate metamaterials that can solve equations

The field of metamaterials involves designing complicated, composite structures, some of which can manipulate electromagnetic waves in ways that are impossible in naturally occurring materials.

Golden ball in a golden cage

Researchers have synthesized a tiny structure from 32 gold atoms. This nanocluster has a core of 12 gold atoms surrounded by a shell of 20 additional gold atoms. The unusual stability of this cluster results from electronic interactions with amido and phosphine ligands bound to its surface.

In a new quantum simulator, light behaves like a magnet

Physicists propose a new 'quantum simulator': a laser-based device that can be used to study a wide range of quantum systems. Studying it, the researchers have found that photons can behave like magnetic dipoles at temperatures close to absolute zero, following the laws of quantum mechanics. The simple simulator can be used to better understand the properties of complex materials under such extreme conditions.

Physicists reveal why matter dominates our universe

Physicists have confirmed that matter and antimatter decay differently for elementary particles containing charmed quarks.

Physicists reveal why matter dominates universe

Physicists in the College of Arts and Sciences at Syracuse University have confirmed that matter and antimatter decay differently for elementary particles containing charmed quarks.

CERN: Study sheds light on one of physics' biggest mysteries – why there's more matter than antimatter

Why do we exist? This is arguably the most profound question there is and one that may seem completely outside the scope of particle physics. But our new experiment at CERN's Large Hadron Collider has taken us a step closer to figuring it out.

The best topological conductor yet: Spiraling crystal is the key to exotic discovery

A team of researchers has discovered the strongest topological conductor yet, in the form of thin crystal samples that have a spiral-staircase structure.

The best topological conductor yet: Spiraling crystal is the key to exotic discovery

The realization of so-called topological materials—which exhibit exotic, defect-resistant properties and are expected to have applications in electronics, optics, quantum computing, and other fields—has opened up a new realm in materials discovery.
