Stable Nickel-64 Nuclei Take Three Distinct Shapes
Scientists have identified three distinct shapes in stable nickel-64 that appear as energy is added to the nucleus. The nucleus in the lowest-energy state is spherical, then takes elongated (prolate) and flattened (oblate) shapes as the protons and neutrons surrounding the nucleus gain energy. This demonstrates profound changes in the way protons and neutrons can arrange themselves.

Isotope Discovery Continues: Mass Identification Confirms Production of a New Isotope of Mendelevium
Neighboring isotopes of the heaviest elements often have very similar properties. To differentiate these isotopes by their differing masses, scientists use a device called FIONA (For the Identification of Nuclide A) to measure the masses of heavy-element isotopes. For the first time, scientists have used FIONA to discover a new heavy-element isotope, mendelevium-244.
Charm Quarks Offer Clues to Confinement
Hadronization occurs when particles called quarks and gluons combine to form hadrons, composite subatomic particles made of two or three quarks. Once combined, quarks and gluons are “confined,” or trapped, in hadrons. Researchers studying particles containing heavy “charm” quarks have found that there are many more three-quark hadrons than expected under a widely accepted explanation of how hadrons can form.
