HughPickens.com writes: Jamie Doward reports at The Guardian that according to a recent study in the UK, the effect of banning mobile phones from school premises adds up to the equivalent of an extra week's schooling over a pupil's academic year with the test scores of students aged 16 improved by 6.4% after schools banned mobile phones, "We found that not only did student achievement improve, but also that low-achieving and low-income students gained the most. We found the impact of banning phones for these students was equivalent to an additional hour a week in school, or to increasing the school year by five days." In the UK, more than 90% of teenagers own a mobile phone; in the US, just under three quarters have one. In a survey conducted in 2001, no school banned mobiles. By 2007, this had risen to 50%, and by 2012 some 98% of schools either did not allow phones on school premises or required them to be handed in at the beginning of the day. But some schools are starting to allow limited use of the devices. New York mayor Bill de Blasio has lifted a 10-year ban on phones on school premises, with the city's chancellor of schools stating that it would reduce inequality.

The research was carried out at Birmingham, London, Leicester and Manchester schools before and after bans were introduced (PDF). It factored in characteristics such as gender, eligibility for free school meals, special educational needs status and prior educational attainment. "Technological advancements are commonly viewed as increasing productivity," write Louis-Philippe Beland and Richard Murphy. "Modern technology is used in the classroom to engage students and improve performance. There are, however, potential drawbacks as well, as they could lead to distractions."

He says it's not just developers, but anyone who is involved, from defining the concept, to requirements gathering, to final implementation. Thus, the creators of the app have an ethical obligation to ensure that people can reach the right conclusions from the facts and the way they are presented in the app.

An anonymous reader sends a report about a new vulnerability found in open source virtualization software QEMU, which is run on hardware in datacenters around the world (CVE-2015-3456). "The cause is a widely-ignored, legacy virtual floppy disk controller that, if sent specially crafted code, can crash the entire hypervisor. That can allow a hacker to break out of their own virtual machine to access other machines — including those owned by other people or companies." The vulnerable code is used in Xen, KVM, and VirtualBox, while VMware, Hyper-V, and Bochs are unaffected. "Dan Kaminsky, a veteran security expert and researcher, said in an email that the bug went unnoticed for more than a decade because almost nobody looked at the legacy disk drive system, which happens to be in almost every virtualization software." The vulnerability has been dubbed "Venom," for "Virtualized Environment Neglected Operations Manipulation."

gollum123 notes new U.S. demographic data from the Pew Research Center which show that the percentage of Americans declaring affiliation with a particular religion has declined sharply since 2007. Americans identifying as Christian dropped from 78.4% in 2007 to 70.6% in 2014. Those describing themselves as atheist, agnostic, or simple having no affiliation took up most of the slack, rising from 16.1% to 22.8%. Members of non-Christian faiths collectively rose from 4.7% to 5.9%. Despite the overall decline, the demographics within the Christian group are getting much more racially and ethnically diverse. The willingness of respondents to marry outside their religious affiliation is also on the rise. The median age of unaffiliated adults is dropping, while the median ages of mainline Protestants and Catholics are rising. The study estimates that 85% of adults age 70 and over are Christian, while only 56% of adults ages 18-24 are Christian. They also say that each individual generation has shown a slight decrease in religious affiliation compared to their statistics in 2007.

Patrick O'Neill writes: "There has not been a tradeoff between liberty and security in our response to terrorism in this country and in our efforts to offer security to the people of the United States," said James Comey, now the director of the FBI. Comey was the number two man in the Department of Justice during the Bush years when NSA and law enforcement surveillance of Americans grew to unprecedented heights. Now he's pushing to stop encryption by default on Apple and Android devices.

An anonymous reader writes: An editorial at Tom's Hardware makes the case that Google's Android fragmentation problem has gotten too big to ignore any longer. Android 5.0 Lollipop and its successor 5.1 have seen very low adoption rates — 9.0% and 0.7% respectively. Almost 40% of users are still on KitKat. 6% lag far behind on Gingerbread and Froyo. The article points out that even Microsoft is now making efforts to both streamline Windows upgrades and adapt Android (and iOS) apps to run on Windows.

If Google doesn't adapt, "it risks having users (slowly but surely) switch to more secure platforms that do give them updates in a timely manner. And if users want those platforms, OEMs will have no choice but to switch to them too, leaving Google with less and less Android adoption." The author also says OEMs and carriers can no longer be trusted to handle operating system updates, because they've proven themselves quite incapable of doing so in a reasonable manner.

sciencehabit writes: Representative Louie Gohmert (R–TX) is worried that scientists employed by the U.S. government have been running roughshod over the rights of Americans in pursuit of their personal political goals. So this week Gohmert, the chair of the oversight and investigations subpanel of the U.S. House of Representatives' Natural Resources Committee, held a hearing to explore "the consequences of politically driven science." Notably absent, however, were any scientists, including those alleged to have gone astray.
