And helium-3/helium-4 fusion into two helium-4s accounts for 3% of the reactions by number, releasing 19.99 MeV of energy for each reaction: 10.8% of the Sun's total energy.

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

But helium is too light to exist on Earth for long. Once it reaches the surface in its gaseous phase -- once it comes out of the rock and makes it into the atmosphere -- it's only a matter of time ...

IN a recent paper1 Fröhlich has tried to interpret the λ-phenomenon of liquid helium as an order–disorder transition between n holes and n helium atoms in a body-centred cubic lattice of 2n ...

Helium is the second-most common element in the cosmos, but it's far rarer on planet Earth. As part of our celebration of the periodic table's 150th birthday, reporter Geoff Brumfiel shares a ...

Boeing's Starliner spacecraft landed uncrewed in a New Mexico desert late on Friday. Sign up here. Past missions have that have been affected by pesky helium leaks include ISRO's Chandrayaan 2 and ...
