Quantum sensing has long promised exquisite sensitivity, but in the real world, environmental noise usually buries the very signals researchers want to see. A new experiment using just three trapped ...

Calcium is a very special nutrient. In the cells of most living beings calcium ions function as so-called second messengers to transmit important signals. The same applies equally to animal, plant and ...

Researchers at the Hong Kong University of Science and Technology have built a calcium-ion battery that retains roughly three-quarters of its capacity after 1,000 charge-discharge cycles, a result ...

The first digital “quantum simulator” based on trapped ions has been built by physicists in Austria. The system, developed by Ben Lanyon and colleagues at the University of Innsbruck, comprises a ...

Renewable energy and electric cars are driving demand for batteries with denser energy storage than standard lithium-ion batteries. Ions that can carry more than one charge, such as calcium and ...

MRI scans can look deep into the brain using powerful magnets to see brain anatomy and structure. Different types of MRI scans including functional MRIs that track blood flow as an indicator of brain ...
