Researchers from the Netherlands Cancer Institute in Amsterdam have discovered a common link between cancer cells and stem cells. Together with colleagues from the University of Zurich, Merel Lingbeek and NWO pioneer Prof. Maarten van Lohuizen published their findings on 18 March 2004 in Nature.
Because cancer cells and stem cells can both reproduce themselves in unlimited numbers, it was suspected that they have something in common. That suspicion proved to be correct. Together with their Swiss colleagues, researchers from the Netherlands Cancer Institute discovered an important common link: the BMI1 gene.
Stem cells, the ’original cells’, develop into specialised body cells by first of all making many copies of themselves. Once this copying process has been completed, they stop dividing and start differentiating into specialised cells, for example, a brain cell. But sometimes this process goes wrong. Instead of differentiating, the stem cells retain the expression pattern of a stem cell and keep on copying themselves. This is how medulloblastomas, the most frequently occurring form of brain cancer in children, can develop.

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...
