NORTHRIDGE, Calif. and BUFFALO, N.Y. — Helium, the second lightest element in the universe, has a variety of uses, from keeping balloons afloat to cooling superconducting magnets. It is also a noble ...

The inner mantles of icy giant planets such as Uranus and Neptune are mainly composed by water, ammonia and methane, while their atmospheres are made of hydrogen and helium. Under high pressures ...

Moscow/Washington, DC -- Although helium is the second most-abundant element (after hydrogen) in the universe, it doesn't play well with others. It is a member of a family of seven elements called the ...

Anyone entering the world of quantum physics must prepare themself for quite a few things unknown in the everyday world: Noble gases form compounds, atoms behave like particles and waves at the same ...

Helium -- essential for many medical and industrial processes -- is in critically short supply worldwide. Production is also associated with significant carbon emissions, contributing to climate ...

Elements in group 18 (formerly group 0) of the periodic table are “inert” no more. Until recently, helium, the “noblest” of the noble gases, was the last one not to have been made into a compound with ...

Everything we can see and touch, and quite a lot that we can’t as well, is made of tiny particles called atoms. Some substances, like particles of this iron, contain only one kind of atom. Iron is an ...

Helium, the second-lightest element in the universe, has a variety of uses, from keeping balloons afloat to cooling superconducting magnets. It is also a noble gas — so labeled because it was long ...

For the first time, an international team of scientists has succeeded in filming quantum physical effects on a helium dimer as it breaks apart. The film shows the superposition of matter waves from ...
