Advances in biomedical imaging are allowing UC Davis researchers to use mice more effectively to study cancers comparable to human disease. The system can distinguish different stages of cancer and could lead to more sensitive screening tests for cancer-fighting drugs.
Positron emission tomography (PET) is widely used for detecting and following cancer in human patients. It works by following short-lived radioactive tracers that are taken up by fast-growing cancer cells.
PET scanners used for humans don’t have the resolution to image an animal as small as a mouse. Researchers led by Simon Cherry, a professor of biomedical engineering at UC Davis, have developed a PET scanner sensitive enough to use with mice, and Craig Abbey, also in the Department of Biomedical Engineering, has developed image analysis methods to use the scanner to monitor tumors.

Researchers led by Francesca Ferlaino from the University of Innsbruck and the Austrian Academy of Sciences report in Physical Review X on the observation of supersolid behavior in dipolar quantum gases of erbium and dysprosium. In the dysprosium gas these properties are unprecedentedly long-lived. This sets the stage for future investigations into the nature of this exotic phase of matter.
Supersolidity is a paradoxical state where the matter is both crystallized and superfluid. Predicted 50 years ago, such a counter-intuitive phase, featuring...

A localization phenomenon boosts the accuracy of solving quantum many-body problems with quantum computers which are otherwise challenging for conventional computers. This brings such digital quantum simulation within reach on quantum devices available today.
Quantum computers promise to solve certain computational problems exponentially faster than any classical machine. “A particularly promising application is the...
