Findings may aid diagnosis and indicate new treatment target for many cancers
A new study from Columbia University Medical Center finds that stomach (gastric) cancer originates from bone marrow derived stem cells (BMDC), rather than from stomach stem cells, as previously thought. The study, "Gastric Cancer Originating from Bone Marrow-Derived Cells" is published in the current issue of Science. "This was an unexpected finding, which may lead to a re-evaluation of current assumptions about how all cancers originate," said Timothy C. Wang, M.D., chief, Division of Digestive and Liver Diseases and Dorothy L. and Daniel H. Silberberg Professor of Medicine at Columbia University College of Physicians and Surgeons and senior author of the study. "The implications of this study may lead to new methods of diagnosis and treatment of many cancers – particularly those that have been linked to chronic inflammation such as stomach, esophagus, lung, pancreas, liver, etc."
A common assumption among cancer specialists is that most cancers originate from tissue stem cells – for example, the gastric stem cells contained in the lining of the stomach. However, the researchers suspected BMDC may contribute to the development or progression of cancer because they are frequently recruited to sites of tissue injury and inflammation, e.g., a typical site for cancer development.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

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...
