Dutch researcher Manon Franssen has shown that cells which heal the skin following an injury play an important role in the development of the skin disease psoriasis. In people with psoriasis, the skin peels much faster than normal so that it flakes and becomes inflamed.
Franssen investigated the transit amplifying cells in the uppermost layer of the skin. These cells develop from stem cells (general unspecialised cells) and specialise into skin cells when new skin cells are needed. The transit amplifying cells are involved in the healing of the skin following an injury and in the regular renewing of the skin.
Normally these cells wait until they receive a signal to develop into skin cells. Franssen discovered that in people with psoriasis, some of the transit amplifying cells divide without waiting for a signal. As a result of this, too many skin cells develop and the skin is renewed more quickly than normal. However, when Franssen cultured the transit amplifying cells from the skin of psoriasis patients, these cells grew less quickly. Exactly how the cell division of transit amplifying cells and stem cells is regulated, is not yet clear.

Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
