The team of OMU Graduate School of Science student Taiga Kobayashi, Specially Appointed Professor Masanori Kohda, Professor Satoshi Awata, and Specially Appointed Researcher Shumpei Sogawa, and Professor Redouan Bshary of Switzerland's University of Neuchâtel, were among the group that last year reported the cleaner wrasse could identify photographs of itself as itself, based on its face through mirror self-recognition.
"The results that fish can use the mirror as a tool can help clarify the similarities between human and non-human animal self-awareness and provide important clues to elucidate how self-awareness has evolved," doctoral candidate Kobayashi declared. In mosquitofish, of the genus Gambusia, male fish are smaller than females -- sometimes only half the size. Biologists had previously assumed that smaller male mosquitofish had at least some ...

'Mirror' nuclei help connect nuclear theory and neutron starsAdding or removing neutrons from an atomic nucleus leads to changes in the size of the nucleus. This in turn causes tiny changes in the energy levels of the atom's electrons, known as isotope shifts. Scientists can use precision measurements of these energy shifts to measure the radius of the nucleus of an isotope.
