Are we born to be optimistic, rather than realistic? Tali Sharot shares new research that suggests our brains are wired to look on the bright side -- and how that can be both dangerous and beneficial.

Information is power. Public education is all about sharing and giving power to people. We need to follow these steps..
This is a very big and exciting announcement!

EdX is a joint partnership between The Massachusetts Institute of Technology (MIT) and Harvard University to offer online learning to millions of people around the world. EdX will offer Harvard and MIT classes online for free. Through this partnership, the institutions aim to extend their collective reach to build a global community of online learners and to improve education for everyone.

MIT’s Director of the Computer Science and Artificial Intelligence Laboratory Anant Agarwal serves as the first president of edX, and Harvard’s Faculty of Arts and Sciences Dean Michael D. Smith leads faculty in developing courses. Along with offering online courses, the institutions will use edX to research how students learn and how technology can facilitate teaching—both on-campus and online.

Slice and Scan brain tissues and post them on the google map...
Amazing Tech..
Our lab needs this..
Invented by Bruce McCormick and his team at Texas A & M University’s Brain Networks Laboratory, the Knife-edge scanning microscope (KESM) combines the job of a tissue slicer and a microscope into a single process. First, the tissue is embedded into a plastic block mold. A custom-made diamond knife then slices the tissue into very thin sections (about half a micrometer thick). A laser illuminates the tissue along the knife’s edge as it’s being cut while images are rapidly captured through a microscope objective.

Because the sectioning and scanning is automated, entire brains scans are a simple matter of letting the KESM do its thing. It takes just under 100 hours to scan a 1 cubic cc block of tissue, which is about the size of a mouse brain. At 300 nm resolution, individual neurons in the brain slices are visible.

Researchers from Chalmers and the University of Gothenburg have shown that nanocellulose stimulates the formation of neural networks. This is the first step toward creating a three-dimensional model of the brain. Such a model could elevate brain research to totally new levels, with regard to Alzheimer’s disease and Parkinson’s disease, for example.

Over a period of two years the research group has been trying to get human nerve cells to grow on nanocellulose.

“This has been a great challenge,” says Paul Gatenholm, Professor of Biopolymer Technology at Chalmers.‟Until recently the cells were dying after a while, since we weren’t able to get them to adhere to the scaffold. But after many experiments we discovered a method to get them to attach to the scaffold by making it more positively charged. Now we have a stable method for cultivating nerve cells on nanocellulose.”

When the nerve cells finally attached to the scaffold they began to develop and generate contacts with one another, so-called synapses. A neural network of hundreds of cells was produced. The researchers can now use electrical impulses and chemical signal substances to generate nerve impulses, that spread through the network in much the same way as they do in the brain. They can also study how nerve cells react with other molecules, such as pharmaceuticals.

The researchers are trying to develop ‟artificial brains”, which may open entirely new possibilities in brain research and health care, and eventually may lead to the development of biocomputers. Initially the group wants to investigate destruction of synapses between nerve cells, which is one of the earliest signs of Alzheimer’s disease. For example, they would like to cultivate nerve cells and study how cells react to the patients' spinal fluid.

fMRI has been applied to almost every aspect of brain science since. It has shown that the brain is highly compartmentalized, with specific regions responsible for tasks such as perceiving faces and weighing up moral responsibility; that the resting brain is in fact humming with activity; and that it may be possible to communicate with patients in a vegetative state by monitoring their brain activity7. In 2010, neuroscientists used fMRI in more than 1,500 published articles.

But researchers readily admit that the technique has flaws. It doesn't measure neuronal activity directly and it is blind to details such as how many neurons are firing, or whether firing in one region amplifies or dampens activity in neighbouring areas. The signal — a boost in blood flow in response to a stimulus — can be difficult to extract from the 'noise' of routine changes in blood flow, and the statistical techniques involved are easy to misunderstand and misuse. “I'm surprised that fMRI has kept going for 20 years,” says Karl Friston, scientific director of University College London's neuroimaging centre. Friston says he thought all the interesting questions would have been “cherry-picked within the first two or three years”.

This is one of the two feature-length documentaries on the Ultimate Matrix Collection. It goes over many philosophical concepts that inspired, and are presented in, the trilogy. They spend the first half on the original film, and the rest of the time then goes over parts 2 and 3, with a couple of things on the Animatrix shorts. This consists of clips of aforementioned releases and interviews. This does a good job of informing the audience about the various thoughts, although it would obviously take far longer to go over all the symbolism in them, and one can ask the very appropriate question if something anywhere near that definite and final is even desired, by viewers or the Wachowskis alike.
