It is still too early to say if any health risks are involved, but medical researcher Fredrik Söderqvist recommends caution in the use of these phones, above all among children and adolescents. Few children who regularly use mobile phones use a headset often or always, even though the Swedish Radiation Safety Authority recommends this.
"Children may be more sensitive than adults to radiation from wireless phones," says Fredrik Söderqvist, who is presenting his research findings in a new doctoral thesis at Örebro University.
One the one hand, he examined the use of wireless telephones among children and adolescents, on the other hand, whether adolescents themselves perceive any health problems that might be related to this use.
He then went on to study blood samples from adults, looking at two so-called biomarkers to see whether mobile wireless phone use has any biological effect on the brain. One of these studies focused on a protein that exists in the so-called blood-cerebrospinal-fluid barrier, which is part of the brain's protection against outside influences. The study revealed an association between use of wireless telephony and increased content of the protein transthyretin in the blood.Self-perceived health problems
"We should all follow the recommendations of the Radiation Safety Authority when it comes to using headsets and avoiding mobile phone use when the coverage is poor."
"The connection was strongest regarding headaches, asthmatic complaints, and impaired concentration. But more research is needed to exclude the effects of other factors and sources of error, even though it is difficult to see how this connection could be fully explained by such factors."Impact may be felt in the future
"This is worrisome, since the possible health effects from long-term exposure to microwaves have not been clarified, especially among children and adolescents. The threshold values in place today protect us from warming, a so-called thermal effect. But if there are mechanisms that are independent of warming, it is not certain that today's thresholds provide protection. And it may be that these are effects that will not be perceived until later on in the future," says Fredrik Söerqvist.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
