Since the 1940s, researchers have created various types of heavy nuclei that don't exist naturally on Earth.
Cloning and Stem Cells is an authoritative peer-reviewed journal, published quarterly in print and online, that focuses on understanding developmental plasticity and defining the molecular mechanisms that regulate differentiation or dedifferentiation of nuclei and cells.

While some nuclei emit a gamma ray as they settle down from excited states, others energize a nearby electron, booting it from the atom.
We have some aggregates which are smaller than the nuclei and some which are larger," says Vekilov.

Similarly, when scientists last year found that people with neurodegenerative disorders such as Huntington's disease have brain cells stuffed with unusual clumps of mutant proteins, many simply assumed that the abnormal buildup inside the cells' nuclei caused the cell death characteristic of the illnesses (SN: 8/16/97, p.
began investigating this problem in 1976, when one of his meteorological balloons passed through an unusual layer of tiny particles and droplets called condensation nuclei, 75,000 feet above Earth's surface.
