If there’s one theme that dominates the last seven days – and, let’s face it, I like to find a theme wherever possible – it’s new mobile devices.

This was followed by Motorola Mobility reinvigorating its RAZR brand by applying it to a high-spec Android smartphone – which in turn was followed by Google and Samsung revealing the Galaxy Nexus.

A newly-published piece of research from Denmark has found that mobile phone use apparently resulted in no increased risks of tumours of the central nervous system.

The study looked at all Danes aged 30 or above and who were born in the country after 1925. Information about the risk of tumours of the central nervous system came from the Danish Cancer Register; this was then processed along with details about mobile phone use.

Manhattan Research has found that 26% of adults in the USA have used their mobile phones for health information or health-related tools in the past 12 months.

Its new Cybercitizen Health U.S. 2011 study, which surveyed over eight thousand adults, shows that the ‘mobile health population’ has more than doubled in the last 12 months. In 2010, just 12% of consumers conducted health activities on their mobile phones.

A UK-wide study has found that one in six mobile phones is contaminated with faecal bacteria.

The most-likely reason, in case you hadn’t already guessed, is apparently due to people failing to wash their hands properly after going to the toilet.
