Submission + - Possible superconductivity in the brain

time961 writes: Pavlo Mikheenko, a superconductivity researcher at the University of Oslo, has published a paper in the Journal of Superconductivity and Novel Magnetism (abstract only; arxiv pre-print here) suggesting that microtubule structures in pig neurons exhibit evidence of superconductivity that could represent a mechanism for quantum computing performed by the brain to achieve the brain's phenomenal information processing power. The observed effects (at room temperature and standard atmospheric pressure) are claimed to indicate a critical temperature of 2022 +/- 157 K, far higher than the 135 K achieved in other materials under similar conditions.

Interesting, if true.

Submission + - Office 2003SP3: Old file formats, now unavailable! 3

They did this because the old formats are "less secure", which actually makes some sense, but only if you got the files from some untrustworthy source.

Naturally, they did this by default, and then documented a mind-bogglingly complex workaround (KB 938810) rather than providing a user interface for adjusting it, or even a set of awkward "Do you really want to do this?" dialog boxes to click through. And, of course, because these are, after all, old file formats, many users will encounter the problem only months or years after the software change, while groping around in dusty and now-inaccessible archives.

One of the better aspects of Office is its extensive compatibility mechanisms for old file formats. At least the support isn't completely gone—it's just really hard to use. Security is important, but there are better ways to fulfill this goal.

This was also covered by the Windows Secrets newsletter, although I can't find a story URL for it."
