A molecule found in nearly all cells plays a vital role in kick-starting the production of key biological molecules involved in inflammation, a group of Salk Institute scientists has discovered. The finding, published in the June 25 issue of Science, may lead to new strategies for blocking the devastating inflammation that lies at the heart of autoimmune disorders such as multiple sclerosis, arthritis, lupus as well as some cancers.
When the cells of the body are confronted with toxic chemicals or disease-causing organisms, such as viruses and bacteria, the immune system mobilizes rapidly to produce an inflammatory response. This army of chemical and cellular defenses is unleashed through a complex chain of molecular events, triggered by master control proteins. These control proteins act as recruiting officers, rallying other proteins to set up the inflammatory defense. One of the most important molecular sergeants is a protein called nuclear factor-kappa B (NF-kB), which can order the production of scores of defensive proteins.
But NF-kB can’t work alone; it requires the help of a complicated complex of other proteins. A team of scientists which included Jeanette Ducut Sigalla, Virgine Bottero and Inder Verma from the Salk Institute together with colleagues from CellGene found that a protein called ELKS is a crucial member of this complex. Verma’s team determined that when ELKS was missing, NF-kB was unable to activate the production of proteins involved in inflammation.

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...
