Gas giants orbiting our sun show a clear pattern; the more massive the planet, the lower the percentage of "heavy" elements (anything other than hydrogen and helium) in the planet's atmosphere. But out in the galaxy, the ...

(Phys.org)—Computers are often described with "ones and zeros," referring to their binary nature: each memory element stores data in two states. But there is no fundamental reason why there should be just two. In a new ...
The stability of atoms can vary considerably from one element to the next, and also between isotopes of the same element (whose nuclei contain the same number of protons but different numbers of neutrons). While many isotopes ...
