Uncorking Superfluid Secrets

A model predicts that an unexpected corkscrew structure transfers rotation from one drop of quantum fluid to another.

The team's numerical modelling predicted the effects of a rotating drop of Bose-Einstein condensate (the lower shape) merging with a static drop (above it). A corkscrew-like structure reflecting the evolving condensate density emerged, showing an entirely different mechanism of transferring rotation than exists in classical fluids.

How MRI Machines Work

New Tool Helps See Ion Binding

This analytical tool helps describe and visualize the results of magnetic resonance experiments in the presence of in vivo ion binding.

The computer based analytical tool is illustrated by visualization of the TQ MR signals inside the traditional TQ RF pulse sequence used to detect bound ions.

Alzheimer’s Advances

High resolution MRI could help monitor and predict the progression of Alzheimer’s disease or even suggest new treatment methods.

Resting state functional MRI at 11.1T revealed the effects on brain microstructures and intrinsic activity due to β-amyloid (Aβ) plaque deposits and inflammation, as indicated by the presence of the inflammatory protein interleukin-6 (IL6).

Topological Semimetals

High magnetic fields are an important tool for discovering and understanding these unique materials that could lead to functional quantum devices.
