The European Commission has approved an investment of €202m for a particle accelerator in the Grenada region of southern ...

In 1975, a paper was published in the prestigious journal Physical Review Letters that was co-authored by a cat. This wasn’t ...

Why did they form at that time? Astronomers know from observing distant exploding stars that the size of the universe has ...

Neutral helium microscopy and atom optics constitute an innovative imaging paradigm that exploits low-energy, charge-neutral helium atoms to non-destructively investigate surface properties at the ...

A new method uses helium droplets combined with ultrashort laser pulses to trigger chemical reactions in a controlled way.

When two hydrogen atoms fuse in the core of the sun, the resulting helium atom weighs less than the two original hydrogen atoms.

Once released, alpha particles can capture electrons from the environment to become helium. If released near the surface, the helium atom is likely to make its way to the atmosphere, and then to ...

An inquest into the 20-year-old’s death has now found Ms. Batistich was “unaware of the inherent dangers of inhaling helium,” and called for warning labels on canisters to be made clearer.

Helium-3 now commands a stable price of around $20 million per kilogram, said Meyerson. Interlune is sharply focused near-term on extracting Helium-3 for superconducting quantum computing ...

A helium atom has two electrons in an energy level outside the nucleus. The atom is neutral as it has two positive protons and two negative electrons.

Many heavy atoms form from a supernova explosion, the remnants of which are shown in this image. NASA/ESA/Hubble Heritage ...
