Electromagnetic fields stimulate the growth of tumors in mice. This is the result of a new study by researchers from Jacobs University in Bremen, Germany, which was commissioned by the Federal Office for Radiation Protection, and published today. The findings do not only confirm a previous pilot study undertaken by the Fraunhofer Institute ITEM in 2010, but expand on the knowledge in two important aspects.
In a study with mice, Alexander Lerchl, Professor of Biology at Jacobs University, and his team could verify that carcinogen-induced tumor rates were significantly higher when the animals were exposed to electromagnetic fields such as those emitted from mobile phones.
“The effects on liver and lung tumors, as reported by ITEM in 2010, were fully confirmed,” says Prof. Lerchl who conducted the investigation together with colleagues from Jacobs University and from the University of Wuppertal. “In addition we found a significantly elevated rate of lymphoma due to exposure,” the scientist explains. Furthermore, some of the effects were seen at levels below the exposure limits for the general population.
Alexander Lerchl, however, does not interpret the new data as being a proof for cancer induction through the use of mobile phones.
“Our results show that electromagnetic fields obviously enhance the growth of tumors. The assumption that they can cause cancer has not been proven so far,” Prof. Lerchl emphasizes, who has published a large number of studies on the topic. Additional research is necessary to clarify the reasons for the latest results findings.
“We can clearly demonstrate the effects. Now new studies must aim at explaining the underlying mechanisms”, Prof. Lerchl concludes.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
