Scientists demonstrated that incidents of electromagnetic interference (EMI) from second and third generation mobile phones occurred at a mere three-centimetre distance.
In this particular study, the research team examined the effects of General Packet Radio Service (GPRS) and Universal Mobile Telecommunications System (UMTS) signals on critical care equipment such as ventilators and pacemakers. Almost 50 EMI incidents were recorded; 75% were significant or hazardous. Hazardous incidents varied from a total switch off and restart of mechanical ventilator and complete stops without alarms in syringe pumps to incorrect pulsing by an external pacemaker.
The second generation (2.5G) GPRS signal caused the highest number of EMI incidents at over 60% whereas the third generation (3G) UMTS signal was responsible for just 13%. EMI incidents also occurred a greater distance with GPRS with a hazardous incident even at three meters.
While first generation mobile phones are used mainly for voice transmission, 2.5G and 3G phones enable internet access, sending and receiving data. They entered the market, however, with little proof regarding their safe use in the medical environment.
Dr Erik van Lieshout, lead researcher from the Academic Medical Center, University of Amsterdam, said; “Our work has real implications for present hospital restrictions of mobile phone use in patient areas.”
“It is unlikely that mobile phone induced EMI in hospitals will be eradicated in the near future so the one meter rule currently in place should continue, as it is relatively safe,” commented Dr van Lieshout.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
