Beryllium-7 is a radioactive isotope of beryllium produced by cosmic rays in the atmosphere. A Japanese research team has explored, over space and time, how the beryllium-7 is transported from the ...

Most of the energy from the sun and other stars comes from a chain of nuclear fusion reactions. The end of this chain is marked by the fusion of protons with beryllium-7 to form boron-8. This process ...

IN their work on cosmic-ray-produced beryllium-7 in rain water at tropical latitudes during the period 1955–59, Rama, Zutshi and Lal 1–3 did not find evidence of the production of this nuclide by ...

Physicists in Europe and North America have measured the radius of an unusual beryllium isotope containing a single neutron a long way from the rest of the nuclear core. Although the radii of other ...

NATURAL radioactivity produced by cosmic rays has general advantages as atmospheric tracers 1,2. Of the many possible isotopes, beryllium-7 has the merits of a large ambient concentration, a ...

An international team has performed one of the world's most sensitive laboratory searches for a subatomic particle called the "sterile neutrino." These hypothetical particles may explain dark matter.

Beryllium is one of those self-loathing elements. Like helium or neon, an atom of beryllium should not partner with another, chemical theory says. But new research, published online May 21 in Science, ...
