Scientists have achieved a major breakthrough in understanding the Universe’s earliest moments, measuring the amount of ...

Helium atom precision measurements and calculations have a history of nearly a century. In the 1960s, theorists discovered that the fine-structure split (23P0-23P2) of the 23P energy level of helium ...

Which is your favourite chemical element? To mark the International Year of the Periodic Table, our science journalists will be arguing for their pick from the 118 known elements. In this instalment, ...

Helium—the lightest atom that can be laser-cooled and controlled—powers a new design for high-powered, stable quantum computers. In a paper published in PRX Quantum, a team led by University of ...

Flash Physics is our daily pick of the latest need-to-know developments from the global physics community selected by Physics World‘s team of editors and reporters Spinning around: half-quantum ...

Physicists from Japan have taken to the skies to grow crystals in zero gravity. Helium crystals were grown using high pressures, extremely low temperatures (0.6K/-272°C) and by splashing them with a ...

Harvard is running out of helium — and it is no laughing matter. A global helium shortage is affecting all sorts of consumers, ranging from the National Weather Service, to party-supply stores, to ...

Researchers at TU Wien and MedAustron have developed a method to measure the carbon-to-helium ratio of a mixed ion beam ...

A device that efficiently transfers single electrons from one grid point to another on the surface of liquid helium could provide a scalable way to make arrays of electron qubits. Figure 1: This ...

A new device for recycling the helium coolant in an MRI scanner or similar machine uses elevated pressure to dramatically increase the rate at which helium is liquefied. Nothing goes to waste. In a ...
