Submission + - iPhone 5 teardown reveals why it is so light (geek.com)

Submitted by Anonymous Coward
An anonymous reader writes: Although the iPhone 5 looks distinctly iPhone-ish, it has in fact been completely redesigned from the larger display to the new dock connector, but what iFixit is most interested in is what’s inside, and they weren’t shy about showing us exactly what’s at the heart of Apple’s latest smartphone.

iFixit figured out how Apple managed to save so much weight while still making the display larger and adding the extra electronics to support LTE. It all comes down to the back casing, which weighs almost the same as just the glass in the 4S. Mystery solved.

Submission + - Your moral compass is reversible (nature.com)

scibri writes: Your moral positions may be more flexible than you think. Researchers in Sweden have tricked people into reversing their opinions on moral issues, even to the point of constructing good arguments to support the opposite of their original positions (paper in PLOS ONE).

They used a "magic trick" to reverse a person's responses to such moral issues as "Large-scale governmental surveillance of e-mail and Internet traffic ought to be forbidden as a means to combat international crime and terrorism", by switching "forbidden" to "permitted" when the subject turned the page of the questionaire. When asked to read back the questions and answers, about half of the subjects did not detect the changes, and a full 53% of participants argued unequivocally for the opposite of their original attitude in at least one of the manipulated statements.
