Victoria Justice - Gold Justin Timberlake - Take Back The Night Взрыв метеорита в небе над Уралом... Вся информация в одном посте. Сегодня с утра в небе над Челябинской областью взорвался метеорит, несколько обломков упали на землю. Зрелище, конечно завораживающее. Взрывной волной повредило сотни зданий, выбиты окна, обрушились некоторые конструкции и балконы. О человеческих жертвах пока не сообщается, но судя по фото с места происшествия, разрушения серьезные. "Более 150 человек пострадали при падении метеорита в Челябинской области" - МВД/РИА новости. Многие автовладельцы записали момент взрыва метеорита на регистраторы (осторожно, авторская овучка): "Представитель Центрального военного округа сообщил РИА Новости, что никаких происшествий с военно-воздушными судами в небе не зафиксировано.

New 17-million-digit monster is largest known prime - physics-math - 05 February 2013 The largest known prime number has just shot up to 257,885,161 - 1, breaking a four-year dry spell in the search for new, ever-larger primes. Curtis Cooper at the University of Central Missouri in Warrensburg made the find as part of the Great Internet Mersenne Prime Search (GIMPS), a distributed computing project designed to hunt for a particular kind of prime number first identified in the 17th century. All prime numbers can only be divided by themselves and 1. The rare Mersenne primes all have the form 2p - 1, where p is itself a prime number. The new prime, which has over 17 million digits, is only the 48th Mersenne prime ever found and the 14th discovered by GIMPS. Volunteer sifters Though there are an infinite number of primes, there is no formula for generating these numbers, so discovering them requires intensive computation. Cooper runs GIMPS software on around a thousand university computers, one of which spent 39 days straight proving that the number was prime. Prizes for primes

Parents need to know homeopathy does not protect against measles, says MP | Society A doctor prepares an MMR injection. Photograph: Rebecca Naden/Reuters The GP and Conservative MP Sarah Wollaston is calling on homeopathy's governing bodies to make it clear to parents that their alternative remedies will not protect children from measles outbreaks. Large numbers of children have not had the MMR (measles, mumps, rubella) vaccine, largely because of the scare that followed the publication of research by Andrew Wakefield in the Lancet medical journal in 1998 that postulated a link between the jab and autism. The research was later discredited and Wakefield was struck off by the General Medical Council for fraud. In Wollaston's constituency of Totnes, Devon, the concern generated by Wakefield lingers on and is part of the reason, she believes, for a general distrust of vaccines and a reliance on homeopathy – remedies that are almost entirely water. "Some parents have an unshakeable belief that homeopathy boosts their child's immune system.
Does international child sponsorship work? New research says yes Child sponsorship is a leading form of direct aid from households in wealthy countries to children in developing countries, with approximately 3.39 billion dollars spent to sponsor 9.14 million children internationally. A new study published in the Journal of Political Economy shows international child sponsorship to result in markedly higher rates of schooling completion and substantially improved adult employment outcomes. Researchers used first-hand survey data from a study of Compassion International, a leading child sponsorship organization, to examine the adult life outcomes of a group of 10,144 individuals in Bolivia, Guatemala, India, Kenya, the Philippines, and Uganda that included children who began sponsorship through the program a generation ago. The study estimates causal effects on adult life outcomes in areas such as educational completion, type of employment, and community leadership.
Big Data, for better or worse: 90% of world's data generated over last two years A full 90% of all the data in the world has been generated over the last two years. The internet companies are awash with data that can be grouped and utilised. Is this a good thing? An increasing amount of data is becoming available on the internet. Each and every one of us is constantly producing and releasing data about ourselves. We do this either by moving around passively -- our behaviour being registered by cameras or card usage -- or by logging onto our PCs and surfing the net. The volumes of data make up what has been designated 'Big Data' -- where data about individuals, groups and periods of time are combined into bigger groups or longer periods of time. Research advantages Petter Bae Brandtzæg of SINTEF ICT points to the huge research centres now developed at internet companies such as Facebook and Google. 'The advantage they have is the enormous volume of data that other social researchers can only dream of,' he says. Short, transitory information Comparing data

A surprising map of the countries that are most and least welcoming to foreigners Click to enlarge. (Max Fisher/Washington Post) Buried several hundred pages into a new World Economic Forum report on global tourism, past the sections on air travel infrastructure and physician density (by which they mean the number of physicians per capita, not the mass-per-cubic-meter of individual doctors), are some very interesting numbers. The results, mapped out above, seem significant beyond just tourism. The WEF gathered the data from late 2011 through late 2012 by asking respondents, "How welcome are foreign visitors in your country?" According to the data, the top three most welcoming countries for foreigners are, in order: Iceland, New Zealand and Morocco. The three countries least welcoming to foreigners are, in order: Bolivia, Venezuela and Russia. Part of what makes these data so interesting is that there is no easy "grand unifying theory" that I can see, no single variable that explains the outcomes.
