China plans to build the first 'clean' commercial nuclear reactor
China is planning to build a thorium-based nuclear reactor that could be cleaner and safer than conventional options.
Nuclear clocks could be 60x as accurate as atomic counterparts, less prone to errors
For years, atomic clocks have been considered the most accurate devices for tracking the slow march towards obsolescence, a subatomic particle vibrating a given number of times per second with relatively few issues. Now the reliability crown might be passed to the nuclear clock, which in addition to sounding gnarly, could prove to be less susceptible to errors from outside stimuli. It goes like this: although an atomic clock will measure a certain number of vibrations per second, external forces such as ambient electric and magnetic fields affect the electrons used in atomic clocks, causing mishaps. The particles used in nuclear clocks that are measured for vibrations -- and thus timekeeping -- can be excited with a relatively low-energy ultraviolet light, allowing for fewer variations from the aforementioned fields. To wit, Corey Campbell and colleagues at the Georgia Institute of Technology in Atlanta have devised a scheme that uses lasers to carefully control the spatial orientation of the electron orbits in atoms. A nuclear clock containing a thorium nucleus controlled in this way would drift by just one second in 200 billion years, the team claims. Before nuclear clocks become a reality, researchers must identify the precise frequency of light needed to excite thorium nuclei; but this is what grad students are for, right?

Insider Trader: Patch 3.2 keeps getting better
Insider Trader is your inside line on making, selling, buying and using player-made products.I love it when a content patch includes some professions love. As the details keep surfacing, patch 3.2 is looking better than ever. In fact, with the upcoming patch, Engineers will finally be able to drop their Gnomish and/or Goblin specialties ("for a fee")! This has been one of those issues, like ugly and buggy cat forms, that has dragged on and on. The materials for Jeeves have also been updated (get the schematic!). If you're wondering just what you should be saving, hop on through the break for that and other patch 3.2 news!
The Queue: Reputation, daily quests, and performance in Dalaran
Welcome back to The Queue, WoW Insider's daily Q&A column where the WoW Insider team answers your questions about the World of Warcraft.Daily quests and reputation has been a really hot topic lately, not only in The Queue but across WoW in general. Some of our questions today will focus on that, but I'd also like to let you guys know that WoW Insider will overall have more information on those things coming really, really soon. Keep an eye on the site today and in the coming days for all of that good stuff.Alright, let's gets started with my2cents' question... Where, if anywhere, is the quartermaster for Valiance Expedition? I'm almost revered and I'm curious to see if there are any rewards available.
Insider Trader: To prospect, smelt, or let alone?
Recently, a reader wrote in with a question that everyone ponders from time to time. When trying to make money from a profession, it can be difficult to determine what to sell, what to convert, and what to avoid doing all together. Here's what she asked:Hello, When making gold from Mining, is it better to Prospect the Ore? Or is it better to just sell the Ores and Bars?Thank you!Regards, Kristy. Taking a break from the faction recipe series to shake things up a bit, let's take a look at how this breaks down.
