In a collaborative project scientists from the Max-Planck-Institute for Molecular Genetics in Berlin (MPI MolGen), Germany and Genomatix with a business in Munich, Germany and Ann Arbor, MI, USA, applied next generation sequencing and analysis methods to generate an unprecedented view at the human transcriptome.
Deep sequencing of transcripts from two human cell lines revealed so far unrecognized complexity and variability of the human transcriptome. They found that 34% of the polyadenylated transcriptome mapped to so far non-annotated genomic regions. Obviously a large number of novel gene candidates are active in the cell lines under study.
In addition, a global survey of mRNA splicing events identified 94,241 splice junctions, of which 4,096 are novel, and showed that exon skipping is the most prevalent form of alternative splicing.
Details are presented in the Science report of Sultan et al. “A Global View of Gene Activity and Alternative Splicing by Deep Sequencing of the Human Transcriptome”, published online at Science Express (www.scienceexpress.org). Annotation and data visualization is publicly available at http://www.genomatix.de/MPI.html .
Dr. Marie-Laure Yaspo, Group Leader at the MPI MolGen and head scientist of the study states: ” Deep sequencing allows for the first time to explore directly the complexity and dynamics of the human transcriptome with a reasonable effort. This will lead to a new picture of the mammalian genome annotation far beyond the current state of the art. We provide here global features of alternative splicing events in human cell lines. Such a comparison of within-cell and between-cell alternative splicing events, combined with the simultaneous analysis of gene expression has never been presented before. It becomes clear that the so far available methods only delivered a part of the transcriptional landscape of mammalian cells, especially if gene regulation analysis is considered”

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...
