Submission + - New Freescale i.MX6 SoCs Include IoT-focused UltraLite (linuxgizmos.com)
__aajbyc7391 writes: Freescale announced three new versions of its popular i.MX6 SoCs, including new DualPlus and QuadPlus parts featuring enhanced GPUs and expanded memory support, and a new low-end, IoT focused 528MHz UltraLite SoC that integrates a more power-efficient, single-core ARM Cortex-A7 architecture. The UltraLite, which will be available in a tiny 9x9mm package, is claimed by Freescale to be the smallest and most energy-efficient ARM based SoC. It has a stripped-down WXGA interface but adds new security, tamper detection, and power management features. All the new Freescale i.MX6 SoCs are supported with Linux BSPs and evaluation kits.

Apart from the economical reasons as outlined by yourself, I always assumed it was a safety issue. I was taught that current kills not Voltage.
That is a common saying but highly misleading and therefore dangerous.
What kills is current through the heart and to some extent the duration of that current. Since we can't really be sure what path current will take through the body during a fault we have to consider current through the body. That current is determined by
1: the impedance of the source
2: the open circuit voltage of the source
3: the impedance of the body
A very high impedance source or a source with minimal total energy available can have a very high open circuit voltage and yet not present a hazard. This is what we see with static electricity.
However when we are talking about shocks off the mains the impedance of the source is negligable. So the important factors are the voltage of the supply and the impedance of the body. A 230V supply is more likely to deliver a fatal shock than a 120V one. This is somewhat mitigated by the fact that things like shuttered sockets and plug cavities/pin insulation are the norm in much of the EU.
The advantages of the higher voltage are efficiency and lower fire risk.

Neil DeGrasse Tyson Urges America To Challenge China To a Space Race 275
An anonymous reader writes: According to a Tuesday story in the UK edition of the International Business Times, Neil deGrasse Tyson, the celebrity astrophysicist and media personality, advocates a space race between the United States and China. The idea is that such a race would spur innovation and cause industry to grow. The Apollo race to the moon caused a similar explosive period of scientific research and engineering development. You might prefer the Sydney Morning Herald piece on which the IB Times article is based.

I would think a kettle would be fine.
With a motorised applicance it will depend on the type of motor. Universal motors will generally be fine (maybe a bit less powerful due to the higher inductance but the design would have to be pretty marginal for that to be relavent). Motors running off DC supplies (e.g. everything you will find in your PC) will be fine too unless the PSU is very marginal. Induction and synchronous motors are more likely to fail.

Black Hole Plays Pool With Plasma 43
the monolith writes: The Hubble Space Telescope is revealing that there is a pool game in progress, with a long shot being played out on a cosmic scale. It appears that the first recorded shot was observed in 1992, while subsequent canon shots were recorded between 1994 an 2014. In actuality, the shots are plasma, the current player is a black hole, and the playing surface is galactic space itself. The BBC has a story on the observations and interpretations, while the journal Nature has the paywalled in-depth article. The current score is unknown, and one can only hope that there were no life forms involved in the collision.

Submission + - Demographers Says Older, Better Educated Women Are Having More Children
HughPickens.com writes: The Economist reports that based on an analysis of census data the proportion of all women who reach their mid-40s without ever having a child has fallen, but the decline is sharpest among the best-educated women. In 1994, 35% of women with a doctoral degree aged 40 to 44 were childless; by last year, this had fallen to 20%. Their families are bigger, too. In 1994, half of women with a master’s degree had had two more or more children. By last year, the figure was 60%. Why might older, better-educated women be having more children? Partly because access to education has widened—and so women who were always going to have children are spending more time in college. Another reason is that fertility treatment has improved dramatically, and access to that, too, has widened. Older women who, in the past, wanted children but were unable to have them are now able to.
But according to demographer Philip Cohen this does not explain the entire leap. Social changes in the nature of marriage seem to be driving the change. Whereas marriage was once near-universal and unequal, in recent decades it has become a deliberate option and more equal. Well-educated women have been able to form strong relationships with similarly brainy men, in which both parents earn and both do some child care. Getting an education and having a career are no longer always a barrier to having children; sometimes, they make it easier. Also as more career-minded women have had children, they have become powerful enough to demand time off from their employers. Although America has no national system of paid maternity leave, many professional firms now offer paid maternity leave—Ernst & Young, an accountancy firm, offers 39 weeks to its employees, for example. Meanwhile poorer women have had little luck of that sort. "Iif I’m a lower-income woman," says Stephanie Coontz, "do I want to hitch myself to a guy who may become just another mouth to feed?”

How a Scientist Fooled Millions With Bizarre Chocolate Diet Claims 260
__roo writes: Did you know chocolate helps you lose weight? You can read all about this great news for chocoholics in the Daily Star, Daily Express, Irish Examiner, and TV shows in Texas and Australia, and even the front page of Bild, Europe's largest daily newspaper. The problem is that it's not true. A researcher who previously worked with Science to do a sting operation on fee-charging open access journals ran a real—but obviously flawed—study rigged to generate false positives, paid €600 to get it published in a fee-charging open access journal, set up a website for a fake institute, and issued press releases to feed the ever-hungry pool of nutrition journalists. The doctor who ran the trial had the idea to use chocolate, because it's a favorite of the "whole food" fanatics. "Bitter chocolate tastes bad, therefore it must be good for you. It's like a religion."
