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 ...

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 ...

Even with regular brushing, teeth can become stained from genetic factors or consuming foods and drinks like tomatoes and coffee. Chemical whiteners can help, but they can also damage teeth in the ...

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 developed a new type of calcium-ion battery that could challenge lithium-ion technology by improving stability and performance.

Calcium ions are essential for cells, but can be toxic in higher concentrations. A team of researchers has now designed and prepared a combination drug that kills tumor cells by modulating the calcium ...
