• Instead of speeding atomic nuclei up, it slows them down, and turns the energy released into electricity.

    ECONOMIST: How to get an energy rush without doughnuts

  • Rabi was interested in the properties of atomic nuclei, not clocks, and he never pursued the idea.

    ECONOMIST: Global positioning: Accuracy is addictive | The

  • But it would help the study of atomic nuclei to know what the correct shape of the proton is.

    ECONOMIST: Protons

  • The energy released by the fusion reactions then heats the surrounding fuel, within which atomic nuclei may further begin to fuse.

    FORBES: U.K. And U.S. Join Forces on Laser-Fusion Energy

  • After they are produced, the quarks and anti-quarks then combine to create protons and neutrons, which themselves combine to produce atomic nuclei.

    FORBES: Scientists Detect Heaviest Known Antimatter Particle

  • When the capacitors are discharged, electrons flow through the gas, knocking the electrons away from the atomic nuclei and thus transforming it into a plasma.

    ECONOMIST: A novel form of fusion power

  • The technique, which relies on stimulating atomic nuclei to give out radio waves, allows the positions of individual atoms in a molecule to be mapped.

    ECONOMIST: This year, the Nobel authorities have shown a deft touch

  • It will examine neutrons (the electrically neutral components of atomic nuclei) that are ejected from the lunar surface after being bombarded by cosmic rays (energetic particles that constantly streak through space).

    ECONOMIST: Divining water

  • To illustrate his proof in the simplest manner consistent with quantum mechanics, Dr Lloyd dreamt up a demon who can detect the characteristics of individual atomic nuclei instead of bouncing molecules.

    ECONOMIST: The cost of forgetting

  • Quarks, the particles from which atomic nuclei are made, were reckoned to have such fractional charges, but since it is impossible to isolate a quark, its charge cannot be measured directly.

    ECONOMIST: The 1998 Nobel prizes

  • It is defined by gravity because that is the only way that it interacts it has no electric charge, and does not feel the strong and weak forces that bind atomic nuclei together.

    ECONOMIST: Research from the beginning of time

  • Using the first completed section of the NOvA neutrino detector, scientists have begun collecting data from cosmic rays-particles produced by a constant rain of atomic nuclei falling on the Earth's atmosphere from space .

    ENGADGET: NOvA neutrino detector captures cosmic rays in 3D, aims to unlock the mysteries of the universe

  • This project, a collaboration between America, Russia, Japan and Europe, is intended to create sustained nuclear fusion by squeezing gases so hard that their atomic nuclei fuse together and give off more energy than was needed to squeeze them.

    ECONOMIST: The diamonds in the rubble

  • Acting alone, gravity would cause stars to collapse completely, but as long as energy is produced at their centers by nuclear fusion (the joining of atomic nuclei to form new elements, as in a hydrogen bomb), the star is heated and puffed up.

    CNN: Why gamma-ray burst shocked scientists

  • According to the standard model these six particles (the flavoured neutrinos and the corresponding electron-like particles) together with another six, the quarks (which make up the protons and neutrons in atomic nuclei), are the irreducible units from which the rest of matter is composed.

    ECONOMIST: Neutrinos

  • In 1966 Kenneth Greisen, Vadim Kuzmin and Georgiy Zatsepin showed that high-energy charged particles (cosmic rays are mostly atomic nuclei, and thus positively charged) should be slowed by collisions with the photons of the cosmic microwave background (radiation left over from the Big Bang that permeates all space).

    ECONOMIST: Cosmic rays: They came from outer space | The

  • Dr Kobayashi and Dr Maskawa, who were at Japan's High Energy Accelerator Research Organisation and Kyoto University respectively, described a type of symmetry breaking that predicted two new families of quarks, a sort of subatomic particle whose simplest members are the ingredients of the protons and neutrons that form atomic nuclei.
