1. Its All Part Of The Show!
After placing an advert in the local newspaper, offering her two poodle puppies for sale, Sally Edwards was amazed to pick up her answer phone message and here the voice of popular comedian Russell Brand asking if the puppies were still for sale.
It was only after rechecking the message sometime later that Ms Edwards overheard what sounded like an "audience" in the background, cheering and clapping Brand's every word.
Slightly bemused by the whole episode, Sally spoke with some of her friends only to find that Brand had been performing locally. Apparently he had commandeered a member of the audience's mobile, taken her number from the local paper and set her up live on the show.
Russell Brand is well known for his flamboyant style, and recently got into trouble for wasting Police time after calling them on his mobile during one of his live shows. Sally reports that the dogs have gone to good homes, and no comedians are involved!
2. The effect mobile phone radiation has on human health is the subject of recent interest and study, as a result of the enormous increase in mobile phone usage throughout the world (as of June 2009[update], there were more than 4.3 billion users worldwide). Mobile phones use electromagnetic radiation in the microwave range, which some believe may be harmful to human health. A large body of research exists, both epidemiological and experimental, in non-human animals and in humans, that shows overall no evidence for harmful effects. Other digital wireless systems, such as data communication networks, produce similar radiation.
The World Health Organization, based upon the consensus view of the scientific and medical communities, has stated that cancer is unlikely to be caused by cellular phones or their base stations and that reviews have found no convincing evidence for other health effects. The WHO expects to make recommendations about mobile phones in 2010. Some national radiation advisory authorities have recommended measures to minimize exposure to their citizens as a precautionary approach.
3 A new type of plastic-based polyaniline, a polymer that has the same characteristics as metal, was unveiled by a team of South Korean scientists. The polyaniline they made can conduct electricity at ultra-cold temperatures, and duplicates traits heretofore found only in pure metallic materials.
The new plastic-based polyaniline is flexible; it can be made pliable, it can mix with other polymers and can be made into any flexible shape required.
However, polyaniline and other conducting polymers do not normally behave as real metals because they are too structurally disordered. Free electrons are therefore "scattered" within the material by the disorder. In metals, in contrast, the electrons are mainly scattered by thermal vibrations of atoms. Since the atoms vibrate less as the metal is cooled, it conducts better at low temperatures
