Bacteria Used To Make Radioactive Metals Inert 237

Serenissima writes "Researcher Judy Wall is experimenting with bacteria that can cleanse the radioactivity from toxic areas by rendering the heavy metals into non-toxic, inert versions. The technology is not without its flaws (the bacteria can't exist in an oxygenated environment yet), but it does have the potential to cleanse some of the world's hazardous sites. From the article: 'The bacteria Wall is studying are bio-corrosives and can change the solubility of heavy metals. They can take uranium and convert it to uraninite, a nearly insoluble substance.'"

Hubble Releases First Post-Upgrade Images 129

Hynee writes "As tweeted, NASA has released 10 new images, all from the new WFC3 instrument and others, including the Cosmic Origins Spectrograph. Images include NGC 6302, Carina Nebula, Stephan's Quintet, Markarian 817, Abell 370, and a few others. Great looking stuff, the WFC3 has twice the resolution of the WF/PC2, on the CCD at least, if memory serves correctly. Eta Carina is a fascinating object, and there are at least two releases in this 'Early Release Observations' set." Here is a video about the new images at Hubblesite.org, and a full HubbleSite.org release page with 56 images.

Why Motivation Is Key For Artificial Intelligence 482

Al writes "MIT neuroscientist Ed Boyden has a column discussing the potential dangers of building super-intelligent machines without building in some sort of motivation or drive. Boyden warns that a very clever AI without a sense of purpose might very well 'realize the impermanence of everything, calculate that the sun will burn out in a few billion years, and decide to play video games for the remainder of its existence.' He also notes that the complexity and uncertainty of the universe could easily overwhelm the decision-making process of this intelligence — a problem that many humans also struggle with. Boyden will give a talk on the subject at the forthcoming Singularity Summit."

There have been many studies linking and many disproving a link between EM radiation and cancer. Even at extremely high levels, most people don't get cancer. In fact, one theory posits that exposure to low-level radiation at early stages can boost the immune system. No one can say either way for certain, because this is all scientific heresy until someone credible crunches the numbers and they are significant. This is happening all the time as science constantly evolving, but at this time 'most' don't recognize this link. Anyone who does is likely a crackpot... reads popular science, orders blueprints, that sort of thing. Now, devil's advocate, imagine the potential ramifications if some credible scientific study came out rigorously pointing to a link between even high-level EM radiation and a carcinogenic effect... The lawsuits would block out the sun. Pandemonium. Economies would fail, and people would starve. Seriously. The world economy could not afford to take that gut-check at this time. It would destroy us. So then, it would be in the best interest of the 'powers that be' to deny, discredit, obfuscate, and in any way DISPROVE a link between EM radiation and cancer. Well-heeled corporations can afford LOTS of 'science'. With as much as they've invested in cell phones, radio, radar systems... imagine asking them to turn it off? Yeah. Suddenly the link is a possibility again. Let's crunch those numbers one more time.

I would like to add to your excellent and highly accurate post, Good Citizen dangitman, as opposed to bothering with some of the idiotic and moronic criticizing posts which follow it: If Wall Street could ever come up with anything remotely as successful as Social Security (an insurance program for the majority), we would all be mightily impressed.

Instead, they keep coming up with an infinite amount of securitized financial scams (or as they call them, "instruments") to continue The Great Financialization.

Comment Metroid, anyone? (Score 1) 130

The absolute best gaming experience I've had when it comes to immersion is definitely Metroid Prime. The game completely blew me away the first time I played it. It's just you, nobody else, on a planet fighting against ETs and Space Pirates while trying to figure out what the heck is going on. Retro Studios never made the game too unlike the previous games in the series as well; this isn't an FPS, it's a First Person Adventure. The puzzles were innovative, expansions were well hidden and fun to find, and the controls, while awkward, worked surprisingly well. The graphics were absolutely beautiful to look at; your HUD would show things like raindrops hitting it or condensation appearing from steam/heat!

The reason why I think the game was so immersive was this: Retro never made players care about the story! The game went on without any real "story" happening. You had to figure out for yourself where to go next, how to beat certain enemies, and everything! You had to "scan" items and enemies to figure out parts of the story and how to defeat enemies. The game gave you this feeling like the world in the game was going on without you animal-crossing style; go to an area one time and something happens, go there another time and different enemies/sequences are present. I was only a pre-teen when I played the game first, so you can imagine how thrilling it was to watch a metroid breaking out of its casing to attack me, and after wondering where to go next for a split second a space-pirate jumps through the window and attacks me.

If more shooters want to be successful, make the design choices that Metroid Prime made.

It's not just a dedicated place of learning, it's a place of research.

Many of the top schools aren't called "top schools" because they teach well. They're top schools because they have to researchers and experts a wide range of subjects who make themselves available to students. If you have a large number of the top people in the world, and they all expect to have the highest salaries of anyone in their line of work, then you have to find a way to increase income to meet their demands. When you see a faculty to student ratio, it can be interpreted as the number of students it takes to pay one person's salary (on average).

This is all on top of providing infrastructure and a vast number of services to enough people to fill a small city (in many cases).
