Today, organisations such as Unesco, the UN body for education, science and culture, are grappling with how schools and universities can respond to rising misinformation and declining trust in ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...

High energy density (HED) physics has critical applications in areas such as inertial confinement fusion and the stewardship of the nation’s nuclear weapons stockpile. Congress has requested that the ...

Understand the energy density of electric and magnetic fields by exploring how energy is stored and distributed in electromagnetic fields. This video explains the underlying physics, key equations, ...

Scientists at a nuclear fusion reactor in China recently surmounted an important obstacle in operating reactor vessels at high density. They pushed plasma density 65% beyond a special threshold, ...

Here’s what you’ll learn when you read this story: The plasma density barrier is a mathematical limit to the density of plasma that can exist in a tokamak before destabilizing. A new study led by a ...

What is density, and how does it apply to the universe? From dogs and water to stars and galaxies, this video uses humor and relatable examples to break down one of the most fundamental concepts in ...

Scientists at China’s Experimental Advanced Superconducting Tokamak (EAST) program rang in the new year with a stunning accomplishment: empirical evidence that they used the device to achieve nuclear ...

Researchers using China’s “artificial sun” fusion reactor have broken through a long-standing density barrier in fusion plasma. The experiment confirmed that plasma can remain stable even at extreme ...

These experimental achievements provide new physical insights into breaking through the long-standing density limit in tokamak operation in pursuit of fusion ignition. "The findings suggest a ...
