Submission + - Your body, the battery: Powering gadgets from human "Biofuel"

Submitted by Anonymous Coward
An anonymous reader writes: This article takes a look at the future of electronic devices powered by the human body. From tiny electric voltage in mammal ears called the endocochlear potential, to body heat, and muscle motion, there are a number of exciting new areas of energy research being explored. Ars reports: "Staying alive guzzles energy. In order to keep us ticking, our bodies need to burn between 2,000 and 2,500 calories per day, which is conveniently enough to power a modestly used smart phone. So if just a fraction of that energy could be siphoned, our bodies could in theory be used to run any number of electronic devices, from medical implants to electronic contact lenses—all without a battery in sight. Recently, researchers have taken important strides toward unlocking this electric potential."

Submission + - New molecular transistor can control single electrons (gizmag.com)

Submitted by Eloking
Eloking writes: Researchers from Germany, Japan and the United States have managed to create a tiny, reliable transistor assembled from a single molecule and a dozen additional atoms. The transistor reportedly operates so precisely that it can control the flow of single electrons, paving the way for the next generation of nanomaterials and miniaturized electronics.

Submission + - Open Document Format 1.2 Published as ISO/IEC Standard (documentfoundation.org)

Submitted by jrepin
jrepin writes: The Open Document Format for Office Applications (ODF) Version 1.2, the native file format of LibreOffice and many other office applications, has been published as International Standard 26300:2015 by ISO/IEC. ODF defines a technical schema for office documents including text documents, spreadsheets, charts and graphical documents like drawings or presentations. The current version of the standard was published in 2011, and then was submitted to ISO/IEC in 2014.

Submission + - More supermassive black holes than we thought! (ras.org.uk)

Submitted by LeadSongDog
LeadSongDog writes: The Royal Astronomical Society advises that, the Nuclear Spectroscopic Telescope Array (NuSTAR) has confirmet the long suspected: many SMBHs are obscured by a surrounding cloud. Observing nine known black holes at X-ray energies not previously visible, they found that five of the nine were emitting much more energetic X-rays than had been known. They so conclude that the SMBHs are much more common than had been known.

I clean my visor with a microfiber cloth and Armor-All (or equivalent). No scratching, no harsh chemical, a well-lubricated surface... The slight, slick residue helps prevent other bugs/debris from sticking in the future. There were three miracle chemicals produced in the last century- Armor-All, WD-40, and silicone (glues/sealers/lubricants/sex toys).

So, what part of "clean" goes with "residue"? Seriously, how do you get that Armor-All crap off?

http://gethuman.com/ will often give you a decent number to get to an actual human in a lot of organizations.

Of course, gethuman.com works better if you have a functioning internet connection. Best to look up the critical numbers in advance and put them in your offline-accessible paper contact list.

And, of course, there was a separate issue of how the court even had jurisdiction over Google, seeing as it does not have any operations, staff or servers in British Columbia.

It's pretty clear that Google is doing business there, or there would be no issue to begin with. Yes, Virginia, advertising is doing business. But then, so is selling mobile phones, tablets, chromebooks, etc., and the one-and-zero stuff that makes them go. This is not dependent on the question of who the frontline salesbot works for.
