Publication: new attempt to replicate Salford's results on blood-brain barrier and RF failed
The aim of this study was to determine whether changes were observed in blood-brain barrier function due to 2-hr single exposure to RF fields at mobile phone frequencies (915 MHz) in rat brains 14 and 50 days after a single 2-h exposure, as reported by Salford et al. (Environ. Health Perspect. 111, 881–883, 203). From the abstract: "No albumin immunoreactivity was observed in the exposed groups. In addition, dark neurons, assessed using hematoxylin and eosin staining, were rarely present, with no statistically significant difference between exposed and sham-exposed animals. This study thus failed to confirm the results of Salford et al."

Lost in Laterality: interpreting "preferred side of the head during mobile phone use and risk of brain tumour"
From the abstract: Due to the highly localized exposure from mobile phones, the preferred side of the head during their use is important information when investigating a possible link with brain tumour risk, but at the same time, error and bias hamper the assessment of this information in case-control studies. Current studies provide evidence of reporting bias insofar as cases appear to over-report the side of the head where the tumour occurred as the one that they preferred in the past when using mobile phones. More refined methods of analysis among only cases or prospective studies with an assessment of the laterality of mobile phone use before the diagnosis of disease are needed to evaluate whether associations seen in some studies are entirely due to reporting bias or a mixture of reporting bias and a causal effect.

Publication: Effects of UMTS Cellular Phones on Human Hearing: Results of the European Project “EMFnEAR:
This article published in the special magazine "Radiation Research" is a scientific publication of the results of the European project "Exposure at UMTS EMF: Study on potential adverse effects on hearing" (EMFnEAR). Conclusion: "It is concluded that UMTS short-term exposure at the maximum output of consumer mobile phones does not cause measurable immediate effects on the human auditory system."

Publication: The association between socioeconomic status and exposure to mobile telecommunication networks in children and adolescents
From the abstract: A potential association between socioeconomic status (SES) and self-reported use of mobile phones has been investigated in a few studies. For this study, interview data of 1,481 children and 1,505 adolescents on participants' mobile phone use, socio-demographic characteristics and potential confounders were taken from the German MobilEe-study. No association between SES and measured exposure to mobile telecommunication networks was seen for children or adolescents. Mobile phone use may differ between status groups with higher use among disadvantaged groups. However, this does not result in higher overall exposure to mobile telecommunication networks. Whether short duration of own mobile phone use or the small numbers of participants with a low SES are causal, have to be investigated in further studies.

'SAR Explained' - new information provided at the "EMF Explained" series website
The EMF Explained Series website serves as an information resource for people interested in a better understanding of radio frequency electromagnetic fields (EMF) and wireless issues. Recently the category “SAR Explained” has been added to the website. Specific Absorption Rate (SAR), SAR-Limit, SAR-measurement and many more topics are explained in depth. The new category will be supplemented by a video that shows pictures of SAR measurements.

BfS workshop summary: "Risk Factors for Childhood Leukaemia"
Summary of the report on non-ionizing radiation: "Epidemiological studies on non-ionizing radiation in the low frequency range (50/60 Hz) have consistently shown an increased leukemia risk from magnetic field strengths above 0.3 -0.4 μT. There is no biological explanation or support from animal studies for such findings. Recent powerful epidemiological studies involving high frequency electromagnetic fields caused e.g. by high power radio and TV transmitter, do not indicate a causal relationship".

New EFHRAN website delivering information on health risk assessment of electromagnetic fields exposure
European Health Risk Assessment Network on Electromagnetic Fields Exposure (EFHRAN) is a project funded by the European Commission - Executive Agency for Health and Consumers (EAHC) with specific objective to establish a network for performing health risk assessment of electromagnetic fields exposure. Project Coordinator is Paolo Ravazzani from the Institute of Biomedical Engineering National Research Council, Milan, Italy.

Two new reviews from ICNIPR
The International Commission on Non-Ionizing Radiation Protection (ICNIRP) has announced the publication of the RF review "Exposure to high frequency electromagnetic fields, biological effects and health consequences (100 kHz-300 GHz)" and the review "Epidemiologic Evidence on Mobile Phones and Tumor Risk". The ICNIRP RF review addresses the current scientific evidence concerning exposure to high frequency electromagnetic fields and the resulting consequences for health. Since the 1998 publication of the ICNIRP guidelines on limiting exposure to electromagnetic fields, there have been important studies published, that needed detailed analysis and discussion to determine their implications for health.

SCENHIR Opinion on Research Needs and Methodology in the domain of radiofrequency electromagnetic fields
The EU Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) has released an opinion on remaining research needs regarding RF EMF and potential health effects. For health effects of RF fields from wireless communication in adults a prospective cohort study is recommended. Interdisciplinary research including dosimetry, epidemiology, and animal studies is recommended for studying health effects of RF fields from wireless communication in children. For RF field mechanisms and verification of important but preliminary findings in vitro, animal or human experiments testing the existence of modulation-specific effects or demodulation of RF signals in biological structures and experimental animal and human studies on EEG patterns and sleep parameters is recommended. SCENIHR adopted this opinion at its 3rd plenary of 6 July 2009.

2nd Edition of Doctors' Manual on the influence of mobile radio on health
The Council of Ministers followed the European Parliament in approving a proposal from the European Commission to modernise European legislation – the so-called GSM Directive – on the use of the radio spectrum needed for mobile services. The updated Directive now allows the 900 MHz frequency band to be used to provide faster, pan-European services such as mobile internet while ensuring the continuation of GSM services. This new flexibility will foster stronger competition on Europe's telecoms market and contribute to a more rapid and more widespread roll-out of wireless broadband services, one of the drivers of economic recovery.
