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.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.
From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
