Who we call and how long we speak to them changes with the weather, according to new research by experts at Newcastle University. Analysing the call patterns of 1.3 million mobile phone users, the team found that in ‘uncomfortable’ weather – such as very hot, humid, wet or cold weather – call length increased but the number of people we made contact with went down.
As part of ongoing research to help prevent and mitigate disruptions to computer networks on the Internet, researchers at Sandia National Laboratories in California have turned their attention to smartphones and other hand-held computing devices.
Sandia cyber researchers linked together 300,000 virtual hand-held computing devices running the Android operating system so they can study large networks of smartphones and find ways to make them more reliable and secure.
Use of smartphones medical images to evaluate stroke patients in remote locations through telemedicine has been reported in USA. The study, the first to test the effectiveness of smartphone teleradiology applications in a real-world telestroke network, was recently published in Stroke, a journal of the American Heart Association.
Near field communication (NFC) is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimetres. Present and anticipated applications include contactless transactions, data exchange, and simplified setup of more complex communications such as Wi-Fi.
The dangers of cell phones have led to preventive policies in France, Israel, Finland, and India, and there are simple ways to minimize the health risks associated with exposure to the radiation energy they emit, according to Devra Lee Davis, PhD, MPH, President of the Environmental Health Trust, in a timely and informative interview featured in Alternative and Complementary Therapies, published by Mary Ann Liebert, Inc.
