Semi-confirmed. Was working on my PC and noticed a that GWX.exe had a window open in the taskbar, and it was throbbing to notify me it wanted attention. I clicked on it and saw: "Your PC has been scheduled to be updated to windows 10 tonight at 10:00. You can choose another time to upgrade." Those were the only two options. I don't remember what I did to cancel the update. But if I hadn't noticed the throbber, or if I hadn't cancelled it, it would have installed automatically.

Method To Repair Damaged Adult Nerves Discovered 128

An anonymous reader writes "Researchers have discovered a promising method to regrow damaged nerves in adults. Brain and spinal-cord injuries typically leave people with permanent impairment because the injured nerve fibers (axons) cannot regrow. A study from Harvard and Carleton University, published in the December 10 issue of the journal Neuron, shows that axons can regenerate vigorously in a mouse model when a gene that suppresses natural growth factors is deleted. Here is the journal article (subscription required to view more than the abstract)."

How To Build a Quantum Propulsion Machine 392

Posted by kdawson on Friday December 11, 2009 @12:02PM from the magnetoelectric-quantum-wheel dept.

KentuckyFC writes "According to quantum mechanics, a vacuum will be filled with electromagnetic waves leaping in and out of existence. It turns out that these waves can have various measurable effects, such as the Casimir-Polder force, which was first measured accurately in 1997. Just how to exploit this force is still not clear. Now, however, a researcher at an Israeli government lab suggests how it could be possible to generate propulsion using the quantum vacuum. The basic idea is that pushing on the electromagnetic fields in the vacuum should generate an equal and opposite force. The suggestion is that this can be done using nanoparticles that interact with the vacuum's electric and magnetic fields, generating the well-known Lorentz force. In most cases, the sum of Lorentz forces adds up to zero. But today's breakthrough is the discovery of various ways to break this symmetry and so use the quantum vacuum to generate a force. The simplest of these is simply to rotate the particles. So the blueprint for a quantum propulsion machine described in the paper is an array of addressable nanoparticles that can be rotated in the required way. Although such a machine will need a source of energy, it generates propulsion without any change in mass. As the research puts it with magesterial understatement, this might have practical implications."
