The process is much more dynamic, involving a miniature molecular machine that must run constantly to keep memories going. Jamming the machine briefly can erase long-term memories." A few months back we discussed a similar removal of rat memories by a different method.

Heartless Gamer writes to mention an Ars Technica article about a dedicated processor for AI performance in games. The product, from a company called AIseek, seeks to do for NPC performance what the PhysX processor does for in-game physics. From the article: "AIseek will offer an SDK for developers that will enable their titles to take advantage of the Intia AI accelerator. According to the company, Intia works by accelerating low-level AI tasks up to 200 times compared to a CPU doing the work on its own. With the acceleration, NPCs will be better at tasks like terrain analysis, line-of-sight sensory simulation, path finding, and even simple movement. In fact, AIseek guarantees that with its coprocessor NPCs will always be able to find the optimal path in any title using the processor." Is this the 'way of the future' for PC titles? Will games powered by specific pieces of hardware become the norm?

fuzzybunny writes "The BBC reports that the IAU's controversial Prague vote on demoting Pluto from planet status was irregular. 'There were 2,700 astronomers in Prague during that 10-day period. But only 10% of them voted this afternoon.'" On a less serious note, lx writes "Nonplussed by Pluto's recent downgrade from Planet Status, Fox News's own John Gibson does an incredible Stephen Colbert impersonation to correct the 'revisionist history' of the IAU's decision. Exemplifying 'truthiness,' from the article: 'Long ago I learned it was a planet and I see no reason to unlearn it. Why should I?' "
