Samsung AllShare Cast Hub hits the FCC, maintains an air of mystery

Image

Details remain decidedly light on this one, but it looks like Samsung could be about to expand its AllShare media streaming / sharing service with a new piece of hardware. A device dubbed the AllShare Cast Hub has now turned up in some FCC filings, apparently packing some HDMI connectivity and dual-band WiFi capabilities. Unfortunately, that's about all that the filings reveal, but it's not too much of a stretch to infer that the device is a media hub of some sort, presumably with the ability to stream media from your computer or smartphone to TVs that don't already support AllShare out of the box. We're guessing Samsung will fill in the rest of the details sooner or later, but those into test reports can dive into the links below right now.

Thirty-five-hour work-week recommended for parents

ScienceDaily (Apr. 23, 2012) ? Swedish mothers of small children work a lot more now than in the 1970s. This is an important reason why so many parents feel extremely pressured for time. One way to handle the stress is to take advantage of the right for Swedish parents to work half time, according to a new doctoral thesis from the University of Gothenburg.

The author of the thesis J?rgen Larsson suggests shorter workweeks for parents.

J?rgen Larsson's doctoral thesis is based on the observation that parents of small children are in the middle of the most hectic part of their lives. One major reason behind the time pressure is that parents work more hours than in the past. The total paid work time for mothers and fathers of small children has increased by an average of 10 hours per week since the 1970s.

The study, which is based on statistical analysis of 20,000 parents and interviews with 19 fathers, explores parents' temporal welfare. Temporal welfare is not only a matter of how pressed for time a person is; it also has to do with how satisfied you are with your allocation of time between for example paid work, children, partner, work at home and time to yourself. The temporal welfare is significantly lower among parents than among people without children at home.

In order to increase their temporal welfare, some parents choose to work part time, so-called parental part time. However, the gender differences in parental part time are much larger than in parental leave (28% of mothers of small children and 2 % of the corresponding fathers choose to work 30-36 hours per week because they have children). This is not only a problem for women but also for men, as it gives them less space to establish close relationships with their children.

Larsson's interviews with men who work paternal part time reveal that their unusual choice is rooted in a desire for their families to escape time pressure, for their children to not have to spend long days in childcare and for themselves to be present with their families. Yet the decision to work paternal part time is closely linked to social class: 5% of higher grade white-collar dads do, whereas the number for blue-collar and lower grade white-collar workers is only 1%.

'Individual time strategies will not be enough to change this pattern. What we need is a new type of time policy at the political level,' says Larsson. 'Such a policy would have to consider the structural obstacles facing fathers who want to work paternal part time, for example that parents with small children are expected to work full time just like everybody else in most workplaces and that the traditional role of a man is incompatible with part-time work.'

'Personally, I'd like to see a voluntary 35-hour workweek for parents of small children. The parents would get a certain government compensation for lost income, maybe for a couple of years. This would give dads an incentive to reduce their work time since a family where both parents work 35 hours a week would get twice the compensation compared to if only the mother works 30-hour workweeks,' says Larsson.

The thesis has already been publicly defended. It can be downloaded at http://hdl.handle.net/2077/28371 (on page 27-31 in the pdf-file there is a summary in English).

Acupuncture can improve skeletal muscle atrophy

ScienceDaily (Apr. 23, 2012) ? A team of Japanese researchers revealed study results? at the Experimental Biology 2012 meeting that show how acupuncture therapy mitigates skeletal muscle loss and holds promise for those seeking improved mobility through muscle rejuvenation.

"It is my hope that this study will demonstrate acupuncture's feasibility with regard to improving health among the elderly and medical patients. Our findings could identify acupuncture as the primary nonpharmacological treatment to prevent skeletal muscle atrophy in the future," says Akiko Onda, an acupuncturist and graduate student at the Waseda University School of Sport Sciences, who has been conducting a series of studies on skeletal muscle atrophy for the past four years. Her presentation was on April 23, at the American Society for Biochemistry and Molecular Biology annual meeting, which is part of EB2012.

Loss of skeletal muscle mass has a profound effect on the ability of the elderly and the sick to engage in physical activity. Because skeletal muscle has high plasticity, interventions such as exercise training, improved nutrition and mechanical stimulation are often recommended to prevent atrophy. Unfortunately, these can be challenging goals for those who are already frail or who have severe medical conditions. Onda insists an alternative nonpharmacological intervention is urgently required, and so she and her collaborators in two labs at Waseda University decided to explore how acupuncture affects skeletal muscle at the molecular level.

"The main focus of this study is changes in the mRNA expression levels of muscle-specific atrophic genes such as atrogin-1," Onda says. "Muscle mass and structure are determined by the balance between protein degradation and synthesis."

The team showed that decreases in muscle mass in mice and in the mRNA expression level of the E3 ubiquitin ligase atrogin-1 can be significantly reversed by acupuncture.

In spite of the World Health Organization's endorsement of acupuncture and the widespread use of acupuncture as a treatment for various diseases, acupuncture is still regarded by many as obscure and suspicious, and its underlying molecular mechanisms are almost completely unknown.

"Our results have uncovered one molecular mechanism responsible for the efficacy of acupuncture treatment and clarified its usefulness in preventing skeletal muscle atrophy in mice," Onda said. "We hope to introduce acupuncture as a new strategy for preventing skeletal muscle atrophy in the future. Further investigations into its molecular mechanisms will help to decrease the medical community's suspicion of acupuncture and provide us with a better understanding of how acupuncture treatment prevents skeletal muscle atrophy."

20 WWII-Era Planes Are About to be Exhumed from a Secret Burmese Location [Planes]

David Cundall, a British aviation enthusiast, has spent 15 years and about $200,000 trying to recover a group of 20 WWII-era Spitfire planes that were buried in 1945 in an undisclosed location in Burma, after being dubbed surplus back in 1945. More »
