Hydrothermal vents and cold seeps were discovered more than 20 years ago, yet remarkably little is known about the biodiversity of these chemosynthetic ecosystems. Deep-sea vents and seeps occur in very different geological settings, yet in both types of systems, microbial primary production supports an abundance of large invertebrates, such as giant tubeworms, clams, and mussels.
These animals in turn provide refuge for a diverse invertebrate fauna. Because seeps are considered to be more stable and less toxic than vents, ecologists expected that diversity would be greater at seeps than at vents, but this hypothesis remained untested until now. In the most recent issue of Ecology Letters, researchers at the College of William and Mary report that diversity is indeed greater in seep mussel beds compared to vent mussel beds.
Lower diversity at vents may be a consequence of a challenging physiological barrier to invasion at vents than at seeps. Moreover, diversity at vents is lowest where spacing between vents is extensive, suggesting that risks of extinction due to
limited dispersal may be important in governing biodiversity in the deep sea.

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.
