As if added fragrance, germfree, odor free and stain free washing were not enough; now we got to cope with soap free as well! The WasH20 washing machine works by breaking down water molecules into OH- and H+ ions; the stains on the linens are "attracted and retained by ions of OH-, while the clothes are sterilized by the H+ ions.""

For some time scientists have tried to make nanosized artificial bone materials using various methods, And have recently turned their attention to mineralised collagen, a nanoapatite/collagen composite. This material is highly biocompatible and has the nanostructure of artificial bone. It could be used in bone grafts and bone-tissue engineering, among other applications."

"Only 65% of MIT graduate students have had sex", writes Jason before breaking down the results by major: "[The chart shows] that 0% of studio art majors were virgins, but 72% of biology majors [...] and 83% of biochem and math majors were virgins!".

Ironically, or perhaps encouragingly, Computer Science majors were further down the bell curve than I personally expected, with roughly 40% of CS Majors declaring virginity. The majors most likely to have virginal scholars are Chemistry, Biochemistry, and Mathematics (physics does not appear on the chart), and the major with the least number of virgins, at 0%, was Studio Art."

Check it out: the program (3 variations), the code, the manual (definitely!), the tests -

also: the model itself (how the mind works), the papers, articles, and confirmations -

- all at http://www.otoom.net/

Yes, the programs do run as of now and exhibit cognitive behaviour.

What I can't do is to get anywhere near the scale of the wetware and move it into a distributive mode.

What's needed therefore is a Unix platform or such, someone who knows about distributed systems, and can access hardware with adequate memory.

PS: in case you're wondering why you haven't heard of it anyway, the answer is on that website too ...

PPS: ... and it is not a 'latest hypothesis'."

Submission + - China's Open Document Format (zdnetasia.com)

And that's nothing to ignore with the largest population of the world under it's governance. The blog starts by pointing out they will most likely merge their current standard with either OOXML or ODF. The bulk of this blog points out why OOXML shouldn't be ISO certified and the biggest problem for Microsoft's standard: "Another Standard, Microsoft does not support, is the specification RFC 3987, which defines UTF-8 capable Internet addresses. Consequently, OOXML does not support, to use Chinese characters within a Web address." This would be problematic for many languages, not just Chinese."
