It might have been good news. Brain tumours and nausea etc that some people attribute to the mobile phone do not appear to be caused by the mobile phone. This should not suprise us as there in no apparent epidemic.

 It is probably right to remain very modestly cautious. However it is a modest caution that is required. The extra text messages I think a mobile-phone supported project may provide will not (I think) cause that much more hazard (if hazard there be).

However  The Department of Health said the precautionary principle set out by Sir William Stewart still stands. This means that any government funded experiments in the value of mobile phones for learning (under 16) are not going to happen. Doh!

From the BBC story mention above:

"But on the issue of cancer, it is more ambiguous. No evidence of a greater short-term risk was found - but researchers said the problem was that cancers do not generally emerge until 10 to 15 years after the event."



Yes, and the GSM system has just celebrated it's 20th anniversary.

According to latest research from the International Journal of Neuroscience, frequent mobile phone use "might" improve mental concentration.

Quote

In the September issue of the International Journal of Neuroscience a study will be published on the long term effects of Mobile Phone use on brain function. Earlier studies have mostly investigated the acute effects of mobile phone use on brain function. However, this study employed an epidemiological approach to investigate the long-term effects of mobile phone use on brain function. In this study data was used from 300 people of which 100 were 'frequent mobile phone users', 100 'non-mobile phone users' and an 'intermediate group' of 100 people. Differences in brain activity (measured using QEEG or quantative EEG), Neuropsychological functions such as attention, memory and executive function and personality traits were assessed.

The results show that frequent mobile phone users score higher on extraversion. Furthermore, frequent mobile phone users showed improved focused attention. This was explained by a learning effect due to making more phone calls in busy environments, whereby people learn to focus better on the phone call and filter out irrelevant environmental information. However, the brain activity from frequent mobile phone users shows more slow activity (increased Delta and Theta) and a slowing of the Alpha Peak Frequency. These effects could not be explained by the differences in personality and focused attention.
