I'm amazed at the production value on this parody ad!

"The US government shut down a series of court cases arising from a multimillion pound business dispute in order to conceal evidence of a damning intelligence failure shortly before the 9/11 attacks, MPs were told.
Moreover, the UK government is now seeking similar powers that could be used to prevent evidence of illegal acts and embarrassing failures from emerging in court, David Davis, the former shadow home secretary, told the Commons."

"A mechanism for memory encoding has now been found."
Research team posits theory that memory could be encoded in the 3 dimensional structure of the neuron cell.
"Memory is attributed to strengthened synaptic connections among particular brain neurons, yet synaptic membrane components are transient, whereas memories can endure. This suggests synaptic information is encoded and ‘hard-wired’ elsewhere, e.g. at molecular levels within the post-synaptic neuron."
"The team looked into structures at the cytoskeletal level of brain structure. They found components that fit together and were capable of creating the information processing and storage capacity that the brain needs to form and retain memory."
Microtubules fill the interiors of our brain's neurons, especially in axons and dendrites where most of the activity takes place. We undertook to find out if this similarity is accidental or not. This led to the generation of a very accurate computational model of the interaction between CaMKII and microtubules. It looks to us that a mechanism for memory encoding has now been found.
The cytoskeleton (also CSK) is a cellular "scaffolding" or "skeleton" contained within a cell's cytoplasm and is made out of protein. The cytoskeleton is present in all cells; it was once thought to be unique to eukaryotes, but recent research has identified the prokaryotic cytoskeleton.

Travis J. A. Craddock
Department of Physics, University of Alberta, Edmonton, Canada
Jack A. Tuszynski
Department of Experimental Oncology, Cross Cancer Institute, Edmonton, Canada
This may also eventually lead to a better understanding of the mechanism behind Alzheimer's disease and it's progression:
"Another paper has been just accepted for publication, based on our collaboration with University of Arizona, Harvard and Boston University, where we propose a molecular mechanism of Alzheimer’s disease progression."
And finally there's another paper related to anesthetic molecules blocking the brian's microtubules:
"A third paper in this series stemming from Travis Craddock’s PhD thesis discusses the effects of anesthetic molecules on memory blockage in brain’s microtubules."
This is another paper I found from 2010 or so from the same group:

wow!!
A small company called ChamTech Operations based in Utah has developed a nanoparticle mix that can be sprayed on any vertical object—like a tree—and make that object act as a high-powered antenna.

This Mindblowing Photo of a World Map In a Water Drop Is Real
(photo réalisée sans trucages !)
You may think that this image recently posted on Reddit is a 3D rendering or some Photoshop trickery, but it's a real photo. A refraction of a world map through a water drop.
It was taken by Markus Reugels, who is an expert on capturing liquids in an awesome way, using a special rig created by himself. He spends weeks in creating images like these, taking about five hundred pictures before obtaining a couple of perfect images. [Flickr, Edemiya and Daily Mail via Reddit]

1,000 Education Apps Organized By Subject & Price
Sure, there are plenty of apps you can use in education. Apple has a whole category dedicated to education in the App store. But how do you really know which ones are worth downloading, or possibly even paying for?
TCEA (Texas Computer Education Association) regularly tests available apps and recommends apps that teachers may be using.The list is organized in Google Docs by subject area and free apps are color coded in white.

Awesome video! Really worth watching!! Last Monday, 30 Dolphins stranded at Arraial do Cabo, Brazil and were quickly saved by local people at the beach.

Scientists to Build a Virtual Brain Henry Markram
A team of Swiss researchers believe they can build a virtual human brain using advances made by neuroscience over the last decade, from modelling the structures of ion channels to the mechanisms of conscious decision-making. "First the scientists must decide on the volume of brain tissue to construct, and, second, they must distribute mathematical models of neurons throughout this volume in a manner consistent with experimental data from real human brains." The project is currently awaiting $1.3 billion from a European science fund.
The plan is controversial, some scientists do not think the plan will work. Others believe that dealing with a virtual brain will prove just as complex and mysterious as working with a real one. Still, the Swiss team envisions a computer that will learn and gradually develop more complex cognitive abilities just like a human brain. If the project gets the go-ahead, researchers have promised to publish the code used to program the brain, meaning limitless experiments could be run on the software, testing virtual drugs against the debilitating diseases that affect the mind.

Below from a TEDTalk from 2009 Henry Markram speaks to the basics of the plans for a supercomputer that models all the brain's 100,000,000,000,000 synapses. (16:49)

Seriously what the hell is wrong with Merikans sticking their fucking noses in someone elses business because of their own political shit-holes they find themselves in.
It is business. Finish and klaar. Plus this pull out will mean a huge financial loss for a shit-load of poor black people in this country whose life savings are plowed into a special purpose investment vehicle in MTN.
So dear Mark Wallace this is not the US, and neither is Iran: Go fuck yourself or pay in the cash you half-witted troglodyte activist. Maybe all companies should pull out of the US seeing that US spies on its own citizens etc as well, pisses on human rights and invaded enough countries to make Iran look like a bunch of peace loving tree huggers.
No "your freedom is not hated" , it is your bullshit attitude and self-centred bullying.

TED 2012 Favorites: Robots that fly...and cooperate
I found this TED talk to be impressive not only in terms of the technology being demonstrated (amazing "news from the future") but also as a masterpiece of teaching. Vijay Kumar doesn't just give a stunning demo of his cooperative flying robots, but also explains how they work. It's a masterpiece of teaching. This is a model TED talk.

As more of the videos from this year's TED go up, I will share the talks that I found most compelling.
