A major study into the safety of mobile phones has concluded that they may affect the health of people who use them. Research carried out by scientists in Finland suggests radiation from mobile phones causes changes in the brain. It is the first time that scientists have looked at the effects of mobile phone radiation on human cells rather than those of rats. The two-year study concluded that even low-level emissions from handsets are damaging. Scientists from the Radiation and Nuclear Safety Authority found that exposing human cells to mobile phone radiation damaged the blood-brain barrier - a safety barrier in the body that stops harmful substances in blood from entering the brain.

They discovered that the exposure caused the cells in blood vessel walls to shrink which enabled molecules to pass into brain tissue. Professor Darius Leszcynski, who carried out the study, said the results came from laboratory tests on human cells and that further research was needed to see if the same effect actually happened in humans. But speaking to BBC News Online, he said: “The blood-brain barrier has been shown to be affected by radiation in animal studies.”There is a lot of uncertainty about whether this happens in humans. We have shown some biological effects.”Prof Leszcynski said these changes could have a serious impact on a person’s health if they were found to happen in humans.”If it did happen it could lead to disturbances, such as headaches, feeling tired or problems with sleeping.

A study by a Swedish research group even suggested it could lead to Alzheimer’s disease.”However, he added: “It is important to remember that our study has been done in the laboratory where we can detect even the smallest changes.

The Nokia N82 was launched on the 14th November, 2007. It’s the latest mobile phone released in the Nokia Nseries. Of course, the Nseries handsets that came before the N82 have done really well with its best performer being the N95. The N95 was launched on 26th September, 2006 which is surprisingly well over a year ago so we are hoping that the N82 feature set has moved on well in advance of the N95.

The key feature set of the N82 can be summarized as :

- Imaging

- Mapping

- Sharing

- Digital scrapbook

The No 1 reason to buy the Nokia N82 must be because of the camera. The Carl Zeiss lens brings state of the art optics for mobile photography and mobile video. The specification for the camera is here :

• Image resolution: up to 5 megapixels (2592 x 1944 pixels)
• Carl Zeiss Optics: Tessar lens, MPEG-4 VGA video capture of up to 30 fps
• F number/Aperture: F2.8
• Focal length 5.6 mm
• Focus range 10 cm ~ infinity
• Macro focus distance 10-50 cm
• Auto focus
• Amber colored auto focus assist light and recording indicator
• Still image file format: JPEG/EXIF
• Auto exposure - center weighted
• Exposure compensation: +2 ~ -2EV at 0.5 step
• White balance: automatic, sunny, cloudy, incandescent, fluorescent
• Scene: automatic, user, close-up, portrait, landscape, sports, night, night portrait
• Color tone: normal, sepia, black & white, negative, vivid
• Zoom: digital up to 20x (5 megapixel up to 6x)
• Xenon flash
• On-device photo editing
• Front camera, CIF (352 x 288 pixels) sensor for video telephony

With a 5 megapixel camera, powerful Xenon flash and Carl Zeiss optics, you can expect the Nokia N82 to deliver really good photographs, even in low-light conditions.To make sure your sharp-shooting skills are enhanced It has fast camera activation, autofocus with a dedicated autofocus assist lamp, fast reloading between shots and DVD-like quality video capture. Don’t overlook the fact that the Nokia N82’s camera has up to 20 times digital zoom.
