Quantum calculations amount to sophisticated estimates. But in 1931, Hans Bethe intuited precisely how a chain of particles ...

Greg Piefer is a UW-Madison College of Engineering product who is bullish about fusion uses today while urging patience over ...

The sun, a searing hot sphere of gas primarily composed of hydrogen and helium, boasts surface and ... The probe recorded data such as particle speed and temperature as the explosion's shock ...

How to answer: A 'description' should include whether the radiation is a wave or particle, its charge (if any) and its composition (eg the number of protons and neutrons or 'is a helium nucleus').

While this is below the 5σ level that is generally accepted as a discovery in particle physics, the observation is in line with the Standard Model of particle physics. The detection therefore helps ...

A research team led by Prof. PAN Jianwei, Prof. WAN Zhensheng and Prof. DENG Youjin from the University of Science and Technology of China (USTC) observed counterflow superfluidity in two-component ...

In a significant new study, researchers suggest that antihelium particles, antimatter twins of helium, picked up by the International Space Station (ISS) may have originated from an undiscovered ...

A pioneering new treatment promises to tackle a wider range of cancers, with fewer side-effects than conventional ...

Fusion technology is a long way from powering a grid — if it ever will. Dozens of fusion startups have launched anyway.

The coldbox is the heart of the PIP-II cryogenic system, cooling helium gas to below the average temperature of outer space. That allows the particle beam to fire at full power without losing ...
