Sony's Crackle arrives on BlackBerry 10, reminds us to not watch Bad Boys II
Slowly, but steadily, BlackBerry's building its BB10 app catalog with some major gets. Today, that burgeoning list grows by a very important one with the addition of Sony's Crackle. The free, ad-based streaming video service, which culls together content from Sony's various TV and film studios, is available to download now from BlackBerry World. It's also compatible with the Q10's teeny, 3.1-inch screen, so if you hate your good eyesight, you can devote an hour or two to reliving the opus that is Bad Boys II. Sure, popular apps like Instagram, Hulu Plus and Netflix have yet to make their way over to BB10, but you can't fault the Waterloo-based outfit for getting users what it can. Even if that means bringing them Bad Boys II.

Teens' self-consciousness linked with specific brain, physiological responses
July 2, 2013 ? Teenagers are famously self-conscious, acutely aware and concerned about what their peers think of them. A new study reveals that this self-consciousness is linked with specific physiological and brain responses that seem to emerge and peak in adolescence.
"Our study identifies adolescence as a unique period of the lifespan in which self-conscious emotion, physiological reactivity, and activity in specific brain areas converge and peak in response to being evaluated by others," says psychological scientist and lead researcher Leah Somerville of Harvard University.
The findings, published in Psychological Science, a journal of the Association for Psychological Science, suggest that teens' sensitivity to social evaluation might be explained by shifts in physiological and brain function during adolescence, in addition to the numerous sociocultural changes that take place during the teen years.
Somerville and colleagues wanted to investigate whether just being looked at -- a minimal social-evaluation situation -- might register with greater importance, arousal, and intensity for adolescents than for either children or adults. The researchers hypothesized that late-developing regions of the brain, such as the medial prefrontal cortex (MPFC), could play a unique role in the way teens monitor these types of social evaluative contexts.
The researchers had 69 participants, ranging in age from 8 to almost 23 years old, come to the lab and complete measures that gauged emotional, physiological, and neural responses to social evaluation.
They told the participants that they would be testing a new video camera embedded in the head coil of a functional MRI scanner. The participants watched a screen indicating whether the camera was "off," "warming up," or "on," and were told that a same-sex peer of about the same age would be watching the video feed and would be able to see them when the camera was on. In reality, there was no camera in the MRI machine.
The consistency and strength of the resulting data took the researchers by surprise: "We were concerned about whether simply being looked at was a strong enough 'social evaluation' to evoke emotional, physiological and neural responses," says Somerville. "Our findings suggest that being watched, and to some extent anticipating being watched, were sufficient to elicit self-conscious emotional responses at each level of measurement."
Specifically, participants' self-reported embarrassment, physiological arousal, and MPFC activation showed reactivity to social evaluation that seemed to converge and peak during adolescence.
Adolescent participants also showed increased functional connectivity between the MPFC and striatum, an area of the brain that mediates motivated behaviors and actions. Somerville and colleagues speculate that the MPFC-striatum pathway may be a route by which social evaluative contexts influence behavior. The link may provide an initial clue as to why teens often engage in riskier behaviors when they're with their peers.

Doctor pleads in malnourished Ohio teen's death
DAYTON, Ohio (AP) ? The doctor of a 14-year-old Ohio girl who had cerebral palsy and weighed just 28 pounds when she died has agreed to plead no contest and give up her medical license.
Fifty-one-year-old Margaret Edwards of Trotwood originally pleaded no contest to three misdemeanor counts of failure to report child abuse or neglect of a functionally impaired person. But in May, she decided to withdraw her plea and got a new attorney.
The Dayton Daily News (http://bit.ly/13iVYHX ) reports that Edwards on Monday changed her mind again and decided to re-enter the plea. She faces up to 18 months in prison at sentencing scheduled for Aug. 6.
Edwards was Makayla Norman's doctor from July 2010 until the girl's March 2011 death from nutritional and medical neglect complicated by her chronic condition.

Cluster spacecraft detects elusive space wind
July 2, 2013 ? A new study provides the first conclusive proof of the existence of a space wind first proposed theoretically over 20 years ago. By analysing data from the European Space Agency's Cluster spacecraft, researcher Iannis Dandouras detected this plasmaspheric wind, so-called because it contributes to the loss of material from the plasmasphere, a donut-shaped region extending above Earth's atmosphere. The results are published today in Annales Geophysicae, a journal of the European Geosciences Union (EGU).
"After long scrutiny of the data, there it was, a slow but steady wind, releasing about 1 kg of plasma every second into the outer magnetosphere: this corresponds to almost 90 tonnes every day. It was definitely one of the nicest surprises I've ever had!" said Dandouras of the Research Institute in Astrophysics and Planetology in Toulouse, France.
The plasmasphere is a region filled with charged particles that takes up the inner part of Earth's magnetosphere, which is dominated by the planet's magnetic field.
To detect the wind, Dandouras analysed the properties of these charged particles, using information collected in the plasmasphere by ESA's Cluster spacecraft. Further, he developed a filtering technique to eliminate noise sources and to look for plasma motion along the radial direction, either directed at Earth or outer space.
As detailed in the new Annales Geophysicae study, the data showed a steady and persistent wind carrying about a kilo of the plasmasphere's material outwards each second at a speed of over 5,000 km/h. This plasma motion was present at all times, even when Earth's magnetic field was not being disturbed by energetic particles coming from the Sun.
Researchers predicted a space wind with these properties over 20 years ago: it is the result of an imbalance between the various forces that govern plasma motion. But direct detection eluded observation until now.
"The plasmaspheric wind is a weak phenomenon, requiring for its detection sensitive instrumentation and detailed measurements of the particles in the plasmasphere and the way they move," explains Dandouras, who is also the vice-president of the EGU Planetary and Solar System Sciences Division.
The wind contributes to the loss of material from Earth's top atmospheric layer and, at the same time, is a source of plasma for the outer magnetosphere above it. Dandouras explains: "The plasmaspheric wind is an important element in the mass budget of the plasmasphere, and has implications on how long it takes to refill this region after it is eroded following a disturbance of the planet's magnetic field. Due to the plasmaspheric wind, supplying plasma -- from the upper atmosphere below it -- to refill the plasmasphere is like pouring matter into a leaky container."
The plasmasphere, the most important plasma reservoir inside the magnetosphere, plays a crucial role in governing the dynamics of Earth's radiation belts. These present a radiation hazard to satellites and to astronauts travelling through them. The plasmasphere's material is also responsible for introducing a delay in the propagation of GPS signals passing through it.
"Understanding the various source and loss mechanisms of plasmaspheric material, and their dependence on the geomagnetic activity conditions, is thus essential for understanding the dynamics of the magnetosphere, and also for understanding the underlying physical mechanisms of some space weather phenomena," says Dandouras.
Michael Pinnock, Editor-in-Chief of Annales Geophysicae recognises the importance of the new result. "It is a very nice proof of the existence of the plasmaspheric wind. It's a significant step forward in validating the theory. Models of the plasmasphere, whether for research purposes or space weather applications (e.g. GPS signal propagation) should now take this phenomenon into account," he wrote in an email.
Similar winds could exist around other planets, providing a way for them to lose atmospheric material into space. Atmospheric escape plays a role in shaping a planet's atmosphere and, hence, its habitability.
