New discovery: Plaice are spotted (on the inside)

22.02.2010
Have you seen a spotted plaice? Probably. However, marine biologist Helen Nilsson Sköld at the University of Gothenburg is the first person to research the spotted insides of plaice.

Many species of animal have skin or fur with intricate pigmentation patterns, which they use for camouflage, communication, regulation of body heat and protection against the sun. A study conducted by researchers at the Department of Marine Ecology at the University of Gothenburg has found that several species of fish also have highly-coloured internal pigmentation.

Adapts to its surroundings

In a study published in Pigment Cell & Melanoma Research, marine biologist Helen Nilsson Sköld and her colleagues show that the number of internal pigment cells has a direct link to the degree of transparency of the fish. Transparent fish can change colour using their internal pigment cells, thus enhancing external skin pigmentation and their ability to adapt to the background colours of their surroundings.

Bewildering display of colour

Mysteriously, plaice also have a high number of internal pigment cells in, for instance, the ear and brain and around their internal organs. Plaice however are not particularly transparent. The internal pigment cells of this fish cannot be seen easily from the outside, which makes its internal display of colour somewhat bewildering.

Unknown functions

According to Helen Nilsson Sköld and her colleagues, the fact that less transparent fish also have this internal pigmentation indicates that the pigment cells may have other, as yet unknown, functions.

"We believe that the internal pigment cells either function as vessels for excess pigment or perhaps provide various forms of protection or contribute to the immune system. We hope to investigate this subject further," says Helen Nilsson Sköld.

Im Focus: Light-induced superconductivity under high pressure

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.

Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
