The universe of microbes that lives in your stomach may be nearly as unique as your fingerprint, according to researchers at the Stanford University School of Medicine who have embarked on the early stages of exploring the intestinal ecosystem.
Using molecular techniques that detect all known types of microbes and borrowing statistical techniques from field ecology and population genetics, Paul Eckburg, MD, a postdoctoral scholar in infectious diseases and geographic medicine, conducted the most extensive study to date surveying the inhabitants of the lower digestive tract. In the three healthy subjects he studied, he found 395 unique bacterial species.
"The intestinal flora is critical to human physiology and a wide spectrum of disease, but the first step in studying this ecosystem is to figure out who is there and how the community census varies in time and space," said Eckburg, the lead author of the study published in this week’s online edition of Science Express. "But even with this large sequencing project, which produced orders of magnitude more sequence data than had been generated in the past, we are not completely there yet. This is just the tip of the iceberg."

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...
