See a pair of superheavy neutron stars collide in this simulation with gravitational wave audio. "An audible tone and a ...

Double-column spectrometer remedies traditional shortcomings to drastically improve counting efficiency and resolution ...

The question of where atoms come from requires a lot of physics to be answered completely – and even then, physicists only have good guesses to explain how some atoms are formed.

About Python module to automatically curate the mass and charge assignments for metabolites in a metabolic model.

The invisible dark matter is one of the universe's biggest mysteries, and its existence is confirmed only by the ...

Richard Feynman, a famous theoretical physicist who won the Nobel Prize, said that if he could pass on only one piece of ...

This single-particle technique allows the determination of each ion’s mass by measuring (simultaneously) the mass–charge ratio and charge of individual ions. Thus, empty and filled ratios can be ...

An atom consists of a heavy center, called the nucleus, made of particles called protons and neutrons. An atom has lighter ...

Such stars are composed almost entirely of neutrons, which are subatomic particles without electrical charge and roughly the same mass as protons.

The neutron is a subatomic hadron particle which has the symbol n or n0, no net electric charge and a mass slightly larger than that of a proton. With the exception of hydrogen, nuclei of atoms ...

Protons and neutrons also have another property - kind of like a different type of charge - that is strong enough to bind ... individuals or organizations control increasing shares of the mass media ...

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