The Swedish Radiation Protection Authority has engaged two internationally well-known epidemiologists to review published epidemiological studies on the relationship between the use of cellular telephones and cancer risk. They are Dr. John D. Boice, Jr. and Dr. Joseph K. McLaughlin from the International Epidemiology Institute, USA.
In their review, no consistent evidence was observed for increased risk of brain cancer, meningioma, acoustic neurinoma, ocular melanoma, or salivary gland cancer, examined over a wide range of exposure measures, including type of phone, duration of use, frequency of use, total cumulative hours of use, tumor location and laterality (concurrence of tumor location with hand normally used during phone conversations).
Dr. Boice and Dr. McLaughlin have also reviewed the Swedish studies by Lennart Hardell et al., which demonstrated an association between the use of cellular phones and cancer. These and a few studies that addressed this concern in the United States are non-informative, either because the follow-up was too short and numbers of cancers too small (USA) or because of serious methodological limitations (Sweden).

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...
