A team of researchers have developed a new method of predicting the number of drug users in the population by looking at the number of recorded overdose deaths among drug users.
In research published today in the American Journal of Epidemiology a team of researchers from Imperial College London, the Health Protection Agency, Medical Research Council and GlaxoSmithKline analysed the numbers of opiate and injecting drug users who had overdoses, to see if it was possible to model long term trends for the number of opiate or injecting drug users. They also found the number of overdoses among opiate and injecting drug users has risen nearly 100 fold in thirty years from around 9 in 1968 to more than 900 by 2000.
Dr Matthew Hickman, from Imperial College London, based at Charing Cross Hospital, and one of the authors of the research, comments: “These results could help provide better data on the true number of drug users in the population and help provide the government with a far better surveillance tool than they currently have. Often the true level of drug use is hidden within populations, but this method could be used to provide a more accurate picture.”

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...

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.
From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
