Actin and ARPs in the nucleus Speculation on the potential role of actin in the nucleus derives largely from its known functions as a cytoskeletal protein 1 (Box 1).

Scientists have uncovered how a newly discovered gene, NEK1, in which mutations have been linked to ALS cases, disrupts the function of the motor neuron and causes it to degenerate and die.

Do eukaryotic cells have a nucleus? Of all the eukaryotic organelles, the nucleus is the most critical. The mere presence of a nucleus is considered one of the defining features of a eukaryotic cell.7 ...

Genes relocated from their correct position in the nucleus cause them to malfunction and this may lead to the heart, blood vessels and muscles breaking down. This new discovery by A*STAR scientists ...

For hundreds of years before this discovery, scientists were puzzled by why heterochromatin clustered at the edge of the nucleus and how it was relevant to normal cell function. This recent discovery ...

Learn what mass number and atomic number tell us about the protons, neutrons and electrons in science's current Rutherford-Bohr model of an atom.

Iowa State astronomers have revealed that a well-known, nearby galaxy has a rare double-nucleus structure. Their paper reporting the discovery is now online and has been accepted for publication ...

Astronomers have revealed that a well-known, nearby galaxy has a rare double-nucleus structure. The so-called "Cocoon Galaxy" not only has a unique shape, it has a rare double-nucleus structure ...
