During chemical reactions, atoms in the reacting substances break their bonds and re-arrange, forming different chemical products. This process entails the movement of both electrons (i.e., negatively ...

Scientists have recently identified electrons and positrons with the highest energies ever recorded on Earth. They provide evidence of cosmic processes emitting colossal amounts of energy, the origins ...

Smashing uranium-238 ions together proves to be a reliable way of imaging their nuclei. High-energy collision experiments reveal nuclear shapes that are strongly elongated and have no symmetry around ...

In the air people breathe, the water on Earth, the stars in the sky and more, atoms are the building blocks that make up the ...

The rainforest in the Amazon basin transpires vast amounts of gaseous isoprene. Until now, it was assumed that this molecule is not transported far up into the atmosphere, as it rapidly declines when ...

The particle collider smashes together atomic nuclei—comprised of particles called protons and neutrons—to break them into their smaller components. Tiffany Bowman / Brookhaven National Laboratory For ...
