Different atoms and ions possess characteristic energy levels. Like a fingerprint, they are unique for each species. Among ...

Technical University of Braunschweig, and the University of Delaware achieved new insight into the inner structure of the ...

Physicists Maria Goeppert Mayer and J. Hans D. Jensen develop a theory of the nucleus as composed of shells of protons and neutrons. It explains why nuclei ...

This study provides a valuable contribution to understanding the functional and molecular organization of the medial nucleus accumbens shell in feeding. Using in vivo imaging, optogenetics, and ...

In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...

Introduction: The ability of conditioned cues to evoke drug craving is considered a critical factor precipitating relapse of drug use. The nucleus accumbens shell (AcbSh) is a structure that mediates ...

Medication Development Program, NIDA IRP, Baltimore, Maryland 21224, United States Medicinal Chemistry Section, NIDA IRP, Baltimore, Maryland 21224, United States Article Views are the ...

Researchers at the Institute of Modern Physics have, for the first time, precisely measured the mass of the elusive, neutron-deficient isotope silicon-22, uncovering evidence that its proton number 14 ...

Since the atomic nucleus was first proposed in 1911, physicists simply assumed it was round. But are the nuclei of atoms really round? Intuitively this shape makes sense and physicists believed it ...
