Scientists have discovered helium-3 beneath northern Minnesota, a rare isotope once thought to exist mainly on the Moon.

A giant, gaping hole that opened up in the Sun's atmosphere has been identified as the source of a surprising abundance of a rare isotope of helium. In late October 2023, the Sun was recorded belching ...

A recent experimental measurement has identified a significant discrepancy between theoretical predictions and the observed behavior of the helium-4 nucleus. The work of an international collaboration ...

The long-held, but unproven idea that helium-4 enters into an exotic phase of matter dubbed a "supersolid" when cooled to extremely low temperatures has been challenged in a new article. The long-held ...

University of California, Berkeley, physicists can now tune in to and hear normally inaudible quantum vibrations, called quantum whistles, enabling them to build very sensitive detectors of rotation ...

What first caused you to doubt that supersolidity was the right explanation for what you and Eunseong Kim published in 2004? In 2004, we reported that some of the moment of inertia of solid helium-4 ...

Scientists at the world’s largest stellarator facility, Wendelstein 7-X (W7-X), have successfully generated high-energy helium-3 ions for the first time. “In the world’s largest stellarator facility, ...

A free neutron outside a nucleus is not stable. It undergoes beta decay at a probability. Over time, the number of free neutrons decreases exponentially at a time constant, which is called the neutron ...

Talk about passing gas: Vast stores of helium are escaping from the steam vents and hot springs of Yellowstone National Park after being trapped within Earth’s crust for up to 2 billion years, ...
