Silver nanowires demonstrate unexpected self-healing mechanism: Potential for flexible electronics Posted: 23 Jan 2015 08:07 AM PST Researchers found that silver nanowires can withstand strong cyclic loads, which is a key attribute needed for flexible electronics.

Stalking versus cyberstalking: Effects on victims, their responses compared Posted: 23 Jan 2015 08:07 AM PST The devastating effects of stalking and cyberstalking – harassing or threatening communication via the Internet – are explored in a new study. Key among the findings is that victims of cyberstalking engage in more 'self-protective' behaviours -- such as changing their normal routines or getting a new email address -- than victims of stalking.

Massive chip design savings to be realized Posted: 23 Jan 2015 05:17 AM PST IT researchers have developed a programming language making the massive costs associated with designing hardware more manageable. Chip manufacturers have been using the same chip design techniques for twenty years now. The current process calls for extensive testing after each design step - a massively expensive state of affairs. The newly developed, so-called  functional  programming language makes it possible to prove, in advance, that a design transformation is a hundred percent error-free.

Improvements in transistors will make flexible plastic computers a reality Posted: 23 Jan 2015 05:12 AM PST Researchers revealed that improvements should soon be expected in the manufacture of transistors that can be used, for example, to make flexible, paper-thin computer screens.

Falls in blood pressure, cholesterol have saved 20,000+ lives in England Posted: 22 Jan 2015 04:39 PM PST Falls in blood pressure and total cholesterol staved off more than 20,000 deaths from coronary heart disease in England between 2000 and 2007, shows a mathematical analysis. The impact of statins was greatest among the most affluent in the population, suggesting that these drugs have helped maintain health inequalities between rich and poor, say the researchers.

Social media can provide support needed to maintain weight loss Posted: 20 Jan 2015 08:12 AM PST Use of social media sites like Facebook can be associated with a significant drop in pounds, especially during the critical maintenance period of a weight loss journey, new research shows.

Simulator determines most effective urban measures aimed at increasing bicycle use within cities Posted: 20 Jan 2015 05:59 AM PST Researchers have developed a computer simulation model that helps city officials decide which improvements can be made to increase the number of bicycle users in the city. The model compares different actions and determines which set of measures are the most adequate according to their impact.
