Social consequences of digital inequality Apr 9th 2015, 12:18 Digital inequalities, defined broadly in terms of people’s internet usage, skills and self-perceptions, should be considered as important as the ‘traditional axes of inequality’ with which we are all familiar: race, class and gender, experts argue. These new forms of inequalities can of course combine with existing social inequalities – and even make them worse by ‘carrying over pre-existing differences in human capital into online settings’.

Devices or divisive: Mobile technology in the classroom Apr 17th 2015, 22:59 Little is known about what teachers think about how mobile technology in the classroom will affect the development of students' non-cognitive skills, such as empathy, self-control, problem solving, and teamwork. Violent video games not linked to aggression in adults with autism Apr 14th 2015, 17:04 Following the 2012 shooting in Newtown, Connecticut, some in the media and the public speculated a link existed between autism spectrum disorder and violence and, in particular, that violent video games may cause gamers with autism to act violently. Now, a study has found evidence to contradict this speculation. It is the first study to test the effects of violent video games on aggression in adults with autism spectrum disorder.

Wearable device turns user's thumbnail into a miniature wireless track pad Apr 16th 2015, 19:53 Researchers are developing a new wearable device that turns the user's thumbnail into a miniature wireless track pad. They envision that the technology could let users control wireless devices when their hands are full -- answering the phone while cooking, for instance. It could also augment other interfaces, allowing someone texting on a cellphone, say, to toggle between symbol sets without interrupting his or her typing. Finally, it could enable subtle communication in circumstances that require it, such as sending a quick text to a child while attending an important meeting.

Invisible inks could help foil counterfeiters of all kinds Apr 22nd 2015, 12:49 Scientists have invented sophisticated fluorescent inks that one day could be used as multicolored barcodes for consumers to authenticate products often counterfeited. Snap a photo with your smartphone, and it will tell you if the item is real and worth your money. These inks, which can be printed using an inkjet printer, are invisible under normal light but visible under ultraviolet light. They give manufacturers and consumers an authentication tool that would be very difficult for counterfeiters to mimic.

Using smartphones to avoid spatial disorientation of elderly Apr 22nd 2015, 12:42 Researchers are using new network operator technologies to locate and send alerts when an old person with mild cognitive impairment (MCI) suffers from episodes of spatial disorientation. Up to the 60% of cases of MCI can cause episodes of spatial disorientation that appear even in zones where the person usually carries out daily tasks such as doing the shopping, going to the health centre or visiting someone. The person goes missing and starts to wander causing not only stress or anxiety, but also dangerous situations. Disorientation of elderly also means a source of concern for their caregivers.

Printing silicon on paper, with lasers Apr 21st 2015, 15:12 In seeking to develop the next generation of micro-electronic transistors, researchers have long sought to find the next best thing to replace silicon. To this end, a wealth of recent research into fully flexible electronic circuitry has focused on various organic and metal-oxide ink materials, which often lack all the favorable electronic properties of silicon but offer superior "printability." Recently, a group of researchers has pioneered a method that allows silicon itself, in the polycrystalline form used in circuitry, to be produced directly on a substrate from liquid silicon ink with a single laser pulse -- potentially ousting its pale usurpers. Ten more years of real money? Apr 21st 2015, 12:44 We will still be using "real" money for at least the next 5 to 10 years, but financial transactions carried out using mobile electronic devices, such as smart phones and tablet computers, will increasingly become the norm during that time period, according to research. Literacy app improves school readiness in at-risk preschoolers Apr 19th 2015, 23:37 Using mobile apps in preschool classrooms may help improve early literacy skills and boost school readiness for low-income children, according to research. "Guided use of an educational app may be a source of motivation and engagement for children in their early years," said the study's author. "The purpose of our study was to examine if a motivating app could accelerate children's learning, which it did." New software analyses the effect of climate change on buildings from the cloud Apr 16th 2015, 12:42 Construction companies have begun to use a simulation software which analyses for the first time the entire life cycle of a building, from creation to deconstruction.

Industrial virtual factory lowers costs and reduces emissions Apr 23rd 2015, 12:51 Scientists have developed a cloud-based, easily customized, modular software platform for improving the sustainability performance of industrial products by lowering production costs and reducing emissions. The platform provides a virtual collaborative environment for organizations that are jointly developing the same product and/or service. The system, created during the recently completed EPES (Eco-Process Engineering System for composition of services to optimise product life-cycle) project, effectively combines a context-aware approach, cloud services, industrial internet, collaborative networks, simulation and assessment of environmental impacts. Reducing big data using ideas from quantum theory makes it easier to interpret Apr 23rd 2015, 12:51 Analysing the large volumes of data gathered by modern businesses and public services is problematic. Traditionally, relationships between the different parts of a network have been  represented  as  simple links, regardless of how many ways they can actually interact, potentially loosing precious information. Only recently a more general framework has been proposed to represent social, technological and biological systems as multilayer networks, piles of ‘layers’ with each one representing a different type of interaction. This approach allows a more comprehensive description of different real-world systems, from transportation networks to societies, but has the drawback of requiring more complex techniques for data analysis and representation.  Reducing big data using ideas from quantum theory makes it easier to interpret Apr 23rd 2015, 12:51 Analysing the large volumes of data gathered by modern businesses and public services is problematic.
