Using a new and first-of-its-kind precision measurement of the nucleus of the rare calcium-48 isotope, nuclear physicists have determined how its 20 protons and 28 neutrons are distributed inside its ...

After a multi-institution team's work computing the calcium-48 nucleus, researchers moved on to a larger, heavier, and more complex isotope -- calcium-52 -- and the results surprised them once again.

Information storage in the nervous system requires transcription triggered by synaptically evoked calcium signals. It has been suggested that translocation of calmodulin into the nucleus, initiated by ...

Two recent studies are changing traditional ideas about transcriptional regulation. In the November 3 Cell, researchers led by Ricardo Dolmetsch at Stanford University, California, report that a ...

Physicists may have found a new “magic number” — a quantity of protons or neutrons that gives an atomic nucleus unusual stability. The most common magic numbers are two, eight, 20, 28, 50, 82 and 126; ...

For decades nuclear physicists have tried to learn more about which elements, or their various isotopes, are "magic." This is not to say that they display supernatural powers. Magic atomic nuclei are ...
