Peter Klavins in the Helium Recovery Facility at the UC Davis Department of Physics and Astronomy. The new facility allows researchers to save on helium, which is limited in supply and increasing in ...

A new magnetic switch that controls the flow of heat has been made by Joäo Ventura and colleagues at the University of Porto in Portugal. At its heart is a cylindrical container that is about three ...

Neutron star: could superfluid helium detect gravitational waves from nearby pulsars like this one? Gravitational waves from nearby pulsars could be detected using just a few kilograms of superfluid ...

Helium leaks are hard to detect, since it is odorless, colorless, tasteless, and does not react with other chemical substances. In Applied Physics Letters, by AIP Publishing, researchers from Nanjing ...

Helium is the simplest element in the periodic table with more than one particle in its nucleus, yet state of the art theory and experiments on it don't add up. When you purchase through links on our ...

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 ...

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 ...

Helium is a noble gas, and its colorless, odorless, and non-reactive properties make it extremely difficult to detect. A Chinese research team has developed a detector using sound waves that can ident ...

When you hit the gas pedal in a car, you get pressed backwards in the seat. That’s physics. So why does a helium balloon dart forward, into the acceleration? Is helium immune to physics? The secret to ...

Department of Physics and Astronomy, Northwestern University, Evanston, Illinois 60208, USA. In the quantum world, particles of the same type are indistinguishable, and there are only two classes of ...

In announcing earlier this month that 45 Party City stores will close, CEO James M. Harrison also remarked on the company’s financial shortfalls in balloon sales, blaming the ongoing helium shortage.
