“Everyone’s saying Facebook’s dead.” A new study explores teens’ strained relationship with the largest social network.

A joint study out today on Teens, Social Media, and Privacy by the Pew Research Center and the Berkman Center for Internet & Society confirms what anecdotal evidence has suggested for some time now: that Facebook is falling out of favor with teenagers.
While the study, which surveyed 156 teens ages 11-19, covers a wide range of issues surrounding privacy and teen internet use, the clearest narrative thread in the focus groups is one that’s troubling for the world's largest social network. According to the study:
In focus groups, many teens expressed waning enthusiasm for Facebook. They dislike the increasing number of adults on the site, get annoyed when their Facebook friends share inane details, and are drained by the “drama” that they described as happening frequently on the site. The stress of needing to manage their reputation on Facebook also contributes to the lack of enthusiasm. Nevertheless, the site is still where a large amount of socializing takes place, and teens feel they need to stay on Facebook in order to not miss out.
Users of sites other than Facebook express greater enthusiasm for their choice.
Those teens who used sites like Twitter and Instagram reported feeling like they could better express themselves on these platforms, where they felt freed from the social expectations and constraints of Facebook. Some teens may migrate their activity and attention to other sites to escape the drama and pressures they find on Facebook, although most still remain active on Facebook as well.
Most telling, though, are the quotes from the teens themselves, which indicate not only fatigue, but the very real concern that the Facebook has simply become another exhausting extension of teens' everyday lives.
For many, Facebook's unlimited ability to post pictures, videos, text, and chat led to too much “drama.”

Others cited concerns that the network so closely mirrored their offline world that they no longer felt “free” on the site.

Heat-related deaths in Manhattan projected to rise 20 percent by the 2020s, study says
Author: jos
A new study from The Earth Institute at Columbia University projects that heat-related fatalities could rise steeply in Manhattan by the 2020s as a result of a warming climate, and that in some worst-case scenarios, “by 90 percent or more by the 2080s.” Researchers involved in the study, which will be published this week in Nature Climate Change, say that this is one of the most comprehensive city-specific studies conducted so far, with combined data from all seasons and application of multiple climate scenarios. “This serves as a reminder that heat events are one of the greatest hazards faced by urban populations around the globe,” climate scientist and coauthor Radley Horton said.
The results add another data point to an overwhelming…

Rain will get more extreme thanks to global warming, says NASA study
Author: Stefanie Jenkins
The forecast for the future of rainfall on Earth is in: over the next hundred years, areas that receive lots of precipitation right now are only going to get wetter, and dry areas will go for longer periods without seeing a drop, according to a new NASA-led study on global warming. “We looked at rainfall of different types,” said William Lau, NASA’s deputy director of atmospheric studies and the lead author of the study, in a phone interview with The Verge. “The extreme heavy rain end the prolonged drought side both increase drastically and are also connected physically.”

A simple Excel calculation error puts a famous economic study under scrutiny
Author: Brittany Turner
Back in 2010, economists Carmen Reinhart and Ken Rogoff published a report that stated countries with a debt-to-GDP (gross domestic product) ratio greater than 90 percent would find it significantly more difficult to grow their economy. Their work was widely cited, and was used as a major part of Paul Ryan’s “Path to Prosperity” budget, but a new study shows that its data is flawed thanks to a mistake many office-workers are familiar with — an incorrect Excel formula. The study from three University of Massachusetts researchers claims a number of flaws in Reinhart and Rogoff’s earlier work, one of which is an Excel coding error that omits data from five countries in the analysis (Next New Deal shows an example of the mistake in its…

NASA and Lockheed Martin finish MAVEN probe, hope to study Mars’ upper skies
Author: Charity Woods
Us humans are remarkably familiar with Mars’ area, yet we have not studied its greater altitudes– an odd inconsistency when the sky plays as much of a part as the soil in determining the world’s environment. We’ll get a much better balance in our research now that NASA and Lockheed Martin have completed constructing the Mars Environment and Volatile Evolution probe, or MAVEN. The robotic craft will find out exactly how rapidly the Martian atmosphere is escaping into area and provide us a better idea of exactly how the planet’s arid landscape became. Lockheed Martin still should carry out space simulation examinations and ship MAVEN to the Kennedy Area Center, however the ship ought to introduce in November and provide results around a year later; that’s a fast turn-around for a probe that could possibly answer riddles extending millions of years.

Stanford seizes 1 million processing cores to study supersonic noise
Author: jos
In brief order, the Sequoia supercomputer and its 1.57 million processing centers will shift to a life of top-secret analysis at the National Nuclear Protection Administration, but till that day comes, analysts are presently working to ensure its seamless operation. Most lately, a group from Stanford took the helm of Sequoia to run computational fluid dynamics simulations– a process that requires a carefully tuned balance of computation, memory and communication parts– in order to better understand engine sound from supersonic jets. As a motivating sign, the group had the ability to effectively push the CFD simulation beyond 1 million cores, which is a first of its kind and bodes effectively for the scalability of the system. This and various other examinations are presently being performed on Sequoia as part of its “shakeout” period, which allows its caretakers to much better understand the capabilities of the IBM BlueGene/Q computer. Should all go well, Sequoia is arranged to begin a life of government work in March. In the meantime, you’ll discover a couple views of the setup after the break.

Study: viewers have no patience for buffering, abandon videos after two seconds of waiting
Author: Brian McKinnell
It’s hardly a surprise that viewership drops the longer it takes for a video to buffer, but a professor has actually evaluated information from 6.7 million distinct visitors to attempt and place some numbers with the trend. According to a paper published by professor Ramesh K. Sitarman of the University of Massachusetts, Amherst, viewers start to abandon a video after a 2 2nd delay, with six percent fading away per second after that. Relying on what kind of user you are, that may seem a bit low, but that could be due to the kinds of videos that Sitarman analyzed. The teacher considered videos under 30 minutes long as “short”– we ‘d presume that your ordinary minute-long YouTube video clip would lose far a lot more users per second of buffering. As shown in the …

NPD study finds average display sizes continuing to rise in all areas but laptops and tablets
Author: James Cliff
Not exactly a huge surprise here, but a new study out from NPD DisplaySearch today has confirmed that the trend towards larger screens in continuing at a steady pace in all but a few key areas. The big exception is “mobile PCs,” which NPD defines as laptops and tablets for its purposes. That area dropped from a 13.6-inch average in 2010 to 12.1-inch in 2012 (with an ever so slight increase to 12.2-inches projected for 2013), a drop that represents a ten percent decrease overall and is largely attributed to the growth of tablets . All other areas have seen small to significant growth in recent years, with LCD TVs growing 9 percent, mobile phones increasing 38 percent, and portable media players jumping 29 percent. The biggest growth, by far, comes in OLED TVs, which have gone from a mere 15-inch average in 2010 to an average of 55-inches today — a growth of 267 percent.

Study: Europeans Quickest To Adopt iOS 6, Overall Updates Growth Continues
Author: Charity Woods
We ’ ve got some brand-new and intriguing numbers to share about iOS 6 adoption three weeks after launch, from a few different sources, both of which show users continue to update to the new mobile OS from Apple. There are also some intriguing differences depending on area, with some nations dragging far behind the UNITED STATE in terms of adoption and some surging far ahead.
First, from Chitika, the news that iOS 6 adoption has actually reached simply a hair shy of 68 percent on iPhone gadgets, based upon a picture taken October 10 of the traffic coming through millions of ad impressions on Chitika ’ s network. The iPad is at 51 percent running iOS 6, passing the tipping point of majority of all users, and the iPod rose to just over 42 percent. Chitika thinks that part of the reason behind the distinctions might be the overabundance of older gadgets still in usage in the iPod portion that could ’ t upgrade to iOS 6, whereas all however first-generation iPads are currently compatible, and iPhones enjoy a quicker turnover cycle with customers thanks to carrier upgrade motivations. Overall, iOS 6 adoption sits at 58.88 percent, according to Chitika ’ s data.
The numbers from Chartboost paint a somewhat different image. Overall, they see iOS 6 adoption sitting at simply under 50 percent. That ’ s still an enhancement from when it revealed growth almost stalling last week, but substantially under Chitika ’ s photo. However both continue to show an upwards trend.
In addition to looking at general OS version adoption, Chartboost additionally broke down country-by-country uptake, and that revealed some interesting variations depending on where individuals are in the world. Top iOS 6-adopting nations consist of Italy (65 percent), Germany (62.3 percent), the Netherlands (60.6 percent) and the UK (57.6 percent). On the other end of the spectrum, China is among the lowest adopting countries, with just 24.5 percent on iOS 6. You could see a number of other countries in the chart below.
One more chart from Chitika below shows just how different nations pile up relative to the USA. The geographical iOS 6 adoption breakdown supplies an intriguing appearance at where users are more excited to be on the newest version, however other factors like device distribution and access to reputable Wi-Fi connections could possibly be at play.
