A lucid dream is a dream in which you know you are dreaming. Typically this happens when the dreamer experiences something strange, and when they stop to question their reality, they realize they are in a dream. Lucid dreams happen naturally on occasion, although some people may have them naturally more often than others. The definition of lucid dreaming may be simple, but there are a lot of misconceptions surrounding it.
Misconceptions
The definition of lucid dreaming may be simple, but just like many other things which are relatively unknown by the public, there are a lot of misconceptions surrounding it.
A dream isn't lucid unless you control it
There is some confusion about the difference between lucidity and dream control. The two are related, but one can happen without the other. <br />
<a name='more'></a>For example, many lucid dreamers experience little or no control in some dreams. On the other hand, it is possible to exercise some dream control without being aware that it is a dream. Typically the dream plot will explain this by making the dreamer believe that they have some sort of god-like power over everything. Dream control, by our definition, can be either conscious or unconscious.
<!--nextpage-->
Lucid dreaming is new age
Because almost everyone has lucid dreams naturally every once in a while, we know that lucid dreaming is not limited by any one viewpoint. There are historical records which speak of lucid dreaming going back thousands of years--so it is hardly a new phenomenon. There is no need to have any spiritual beliefs to enjoy lucid dreams.
Lucid dreaming advocates escapism
Lucid dreaming occurs while you are sleeping; it is not meant at all to infringe upon your involvement in the real world. While many lucid dreamers enjoy writing down their dreams, talking about their dreams, and planning fun lucid dreams, this is generally no different from any other hobby. In fact, playing a video game or watching a movie will take you out of the “real world” more than lucid dreaming will.
Lucid dreaming is unnatural, involves "dark arts," or is occult related
Many religious or spiritual sects lump lucid dreaming in with occult practices and activities. Lucid dreams often occur naturally and there is nothing occult about them. On the contrary, many great religious epiphanies and messages came in the form of dreams; sometimes lucid dreams. Our dreams are what we make them; whether we wish to give them spiritual significance or not is up to us.
Dreams contain messages that are lost with lucid dreaming
As of this writing, there are many theories about why dreams exist and what purpose they serve, but so far none of these theories has been proven. One theory is that our dreams contain important or useful messages about our lives. Considering that many people do not even remember their dreams, let alone pay them any attention, changing the dream plot in a fraction of one's dreams is in comparison not nearly as problematic for any message-sending done through dreams. Lucid dreaming also requires very good dream recall, so even if a fraction of these messages are lost in lucid dreams, you are likely remembering many more regular dreams than you ever did before, and on top of that, giving them more attention than ever. Lastly, if we consider that it is our mind that gives us the message through dreams, even if lucid, there is high chances that the message will show regardless.
Levels of Lucidity & Dream Control
Lucid dreaming was defined as becoming aware you are dreaming; the actual level of awareness varies, however. When the level of lucidity is high you are well aware that nothing you experience is real, and you realize that you have nothing to fear—you cannot be harmed by any situations that may seem precarious. With low-level lucidity, although partially aware you are dreaming, you are not aware enough to have a great impact on your dream—you may accept some aspects of your dream that you would not normally accept in the ordinary world (you may not find it at all strange that your dog flies around the living room, etc.) With low-level lucidity your realization may also quickly fade and you may accept the whole dream as reality.
A lucid dream is a completely natural and healthy experience. It is just like any other dream except for the small difference of your knowledge that it is a dream. It has nothing to do with new age, the occult, or escapism, nor can it harm you any more than a regular dream could.

<img alt="" class="aligncenter" height="292" src="http://www.nano.gov/sites/default/files/feynman.jpg" title="nanotech" width="358" /> </div>
<br />
<div style="text-align: center;">
Nanotechnology is science, engineering, and technology conducted at the nanoscale, which is about 1 to 100 nanometers.
Physicist Richard Feynman, the father of nanotechnology.
Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering. Nanotechnology is not just a new field of science and engineering, but a new way of looking at and studying .
The ideas and concepts behind nanoscience and nanotechnology started with a talk entitled “There’s Plenty of Room at the Bottom” by physicist Richard Feynman at an American Physical Society meeting at the </div>
<a name='more'></a>California Institute of Technology (CalTech) on December 29, 1959, long before the term nanotechnology was used. In his talk, Feynman described a process in which scientists would be able to manipulate and control individual atoms and molecules. Over a decade later, in his explorations of ultraprecision machining, Professor Norio Taniguchi coined the term nanotechnology. It wasn't until 1981, with the development of the scanning tunneling microscope that could "see" individual atoms, that modern nanotechnology began.
It’s hard to imagine just how small nanotechnology is. One nanometer is a billionth of a meter, or 10-9 of a meter. Here are a few illustrative examples:
There are 25,400,000 nanometers in an inch
A sheet of newspaper is about 100,000 nanometers thick
On a comparative scale, if a marble were a nanometer, then one meter would be the size of the Earth
Nanoscience and nanotechnology involve the ability to see and to control individual atoms and molecules. Everything on Earth is made up of atoms—the food we eat, the clothes we wear, the buildings and houses we live in, and our own bodies.
But something as small as an atom is impossible to see with the naked eye. In fact, it’s impossible to see with the microscopes typically used in a high school science classes. The microscopes needed to see things at the nanoscale were invented relatively recently—about 30 years ago.
Once scientists had the right tools, such as the scanning tunneling microscope (STM) and the atomic force microscope (AFM), the age of nanotechnology was born.
Although modern nanoscience and nanotechnology are quite new, nanoscale materials were used for centuries. Alternate-sized gold and silver particles created colors in the stained glass windows of medieval churches hundreds of years ago. The artists back then just didn’t know that the process they used to create these beautiful works of art actually led to changes in the composition of the materials they were working with.
Today's scientists and engineers are finding a wide variety of ways to deliberately make materials at the nanoscale to take advantage of their enhanced properties such as higher strength, lighter weight, increased control of light spectrum, and greater chemical reactivity than their larger-scale counterparts.
Conflicting Definitions
Unfortunately, conflicting definitions of nanotechnology and blurry distinctions between significantly different fields have complicated the effort to understand the differences and develop sensible, effective policy.
The risks of today's nanoscale technologies (nanoparticle toxicity, etc.) cannot be treated the same as the risks of longer-term molecular manufacturing (economic disruption, unstable arms race, etc.). It is a mistake to put them together in one basket for policy consideration—each is important to address, but they offer different problems and will require different solutions. As used today, the term nanotechnology usually refers to a broad collection of mostly disconnected fields. Essentially, anything sufficiently small and interesting can be called nanotechnology. Much of it is harmless. For the rest, much of the harm is of familiar and limited quality. But as we will see, molecular manufacturing will bring unfamiliar risks and new classes of problems.
<img alt="" class="aligncenter" height="247" src="http://www.crnano.org/srg-iii-pov-animation2.gif" title="nanotech2" width="300" /><br />
<br />
General-Purpose Technology
Nanotechnology is sometimes referred to as a general-purpose technology. That's because in its advanced form it will have significant impact on almost all industries and all areas of society. It will offer better built, longer lasting, cleaner, safer, and smarter products for the home, for communications, for medicine, for transportation, for agriculture, and for industry in general.
Imagine a medical device that travels through the human body to seek out and destroy small clusters of cancerous cells before they can spread. Or a box no larger than a sugar cube that contains the entire contents of the Library of Congress. Or materials much lighter than steel that possess ten times as much strength. — U.S. National Science Foundation
Exponential Proliferation
Nanotechnology not only will allow making many high-quality products at very low cost, but it will allow making new nanofactories at the same low cost and at the same rapid speed. This unique (outside of biology, that is) ability to reproduce its own means of production is why nanotech is said to be an exponential technology. It represents a manufacturing system that will be able to make more manufacturing systems—factories that can build factories—rapidly, cheaply, and cleanly. The means of production will be able to reproduce exponentially, so in just a few weeks a few nanofactories conceivably could become billions. It is a revolutionary, transformative, powerful, and potentially very dangerous—or beneficial—technology.
How soon will all this come about? Conservative estimates usually say 20 to 30 years from now, or even much later than that. However, CRN is concerned that it may occur sooner, quite possibly within the next decade. This is because of the rapid progress being made in enabling technologies, such as optics, nanolithography, mechanochemistry and 3D prototyping. If it does arrive that soon, we may not be adequately prepared, and the consequences could be severe.
We believe it's not too early to begin asking some tough questions and facing the issues:
Who will own the technology?
Will it be heavily restricted, or widely available?
What will it do to the gap between rich and poor?
How can dangerous weapons be controlled, and perilous arms races be prevented?
Many of these questions were first raised over a decade ago, and have not yet been answered. If the questions are not answered with deliberation, answers will evolve independently and will take us by surprise; the surprise is likely to be unpleasant.
It is difficult to say for sure how soon this technology will mature, partly because it's possible (especially in countries that do not have open societies) that clandestine military or industrial development programs have been going on for years without our knowledge.
We cannot say with certainty that full-scale nanotechnology will not be developed with the next ten years, or even five years. It may take longer than that, but prudence—and possibly our survival—demands that we prepare now for the earliest plausible development scenario.

The brain-computer interface will be a critical component for extreme human life extension.
Such connections will allow the human brain and mind to expand beyond its current limits and could potentially allow one’s consciousness to long outlive outlive one’s body.
We are at the first steps of this inevitable journey, and the work of researchers at the University of Wisconsin appears to be laying the groundwork.<br />
<a name='more'></a>
Scientists there have first created silicon-geranium nanotubes. Then they placed them into a culture of mouse neurons.
There they found the dendrites from the nerve cells were drawn to explore and grow into and through the tubes and even follow their structural architecture.
In the next stage of research the tubes will be made into functional silicon transistor chips that will be capable both of reading electric signals from the dendrites as well as stimulating them. This would then form the basis of future brain-machine interfaces.
“There’s a lot of nontrivial engineering that has to happen, that’s the real challenge,” said one expert. “It’s really cool engineering, but what it means for neuroscience remains to be seen.”

<img alt="" class="aligncenter" height="156" src="http://bruceeisner.com/new_culture/wp-content/uploads/2011/12/emotive-developers-logo.png" title="brain" width="400" /></div>
In the year and a half since I posted Control Your Computer With Your Brainwaves — TED Conference Video which highlighted a presentation at the Ted Conference by Tan Lee, from the EEG biofeedback device developer Emotive Systems the development of Brain Computer Interface (BCI) has accelerated at an amazing rate. In fact the acronym BCI is used so widely that when I saw it the first few times on some of the sites I am going to mention in this post, I was not sure what it represented.
For example, there is a UK blog called thinktech with the tagline The UK’s Leading Brain-Computer Interface, Mind Controlled <br />
<a name='more'></a>& Neurotechnology Gadget Blog which I stumbled upon while Googling on the subject which first tipped me off about the rapid proliferation of BCI that has taken place. I would recommend taking a look at that blog to get a notion of the diversity of development taking place.
Just in the past couple of years, a number of devices which use EEG biofeedback have become available at prices which most would consider affordable. You can get a rundown of these devides on one of those thematic Wikipedia pages that have begun popping up a lot recently called Comparison of Computer brain-computer interfaces.
I recently purchased one of these gadgets called Neurosky Mindwave at a web store appropriately named ThinkGeek. Until recently, the cheapest mobile EEG biofeedback device cost over a thousand dollers but this one cost under a hundred bucks.
Neurosky developed a complete brain wave biofeedback device on a small circuit board that it uses in Mindwave as well as some some higher end devices targets at researchers and rich people. It also licenses the board for other companies to use. Toymaker Mattel uses the board popular toys Mindflex and Mindflex Duel Another company Uncle Milton Science Toys makes a toy called Star Wars Science – Force Trainer.<br />
<br />
<div style="text-align: center;">
<img alt="" class="aligncenter" height="332" src="http://bruceeisner.com/new_culture/wp-content/uploads/2011/12/neurosky-mindwave-package.gif" title="headset" width="500" /> </div>
<br />
The Mindwave device is not aimed at kids but rather at adult geeks like myself. So I spent a few hours playing around with the device. Although Mindwave is packaged Apple style in a artfully decorated boy with just the headset, a USB dongle and a CD-ROM, using the device is anything but simple. I’ve used similar types of devices before in my role as head of the Mindware catalog and before that in a college class at UC Santa Cruz back in the late seventies with the guy who invented biofeedback. Dr. Joe Kamiya.
All of those credentials did not make using Mindwave any easier. I first hooked it to one of my Windows Workstations. I installed the software and it even updated itself from the Internet. Putting on the headset was fairly awkward and when i went to the Neorsky website, I found out that there were several more sophisticated headsets which did not use plastic and which apparently made it easier to clip one part of the headset to your ear and press the other to your forehead without inflicting quite as much pain as I did on my try.
Worst of all, once all properly set up, I could not get any of the applications what came with the device to register my brainwaves. I went to the Neurosky app store and found out that there were hundreds of apps for the device. Neurosky has made available a developers toolkit and created a software API for the device. Unfortunately the most promising ones I could find in their app catalog were fairly expensive.
I finally downloaded a 14 day demo of a Windows program called Mind Workstation by a developer I know called Transparent Corp. The program has built in drivers for the Mindwave as well as other devices by Neurosky, Emotive and several more. However, again no luck. So I gave up for the day.
Thinking about the situation later, I had an aha moment remembering when I demoed a another device of its type and found that it worked better with my Macintosh than with Windows. So I gave it a shot and and after another hour or some of trial and error, I managed to get one of the supplied programs called Meditation Journal to display my brain waves.
That was about an hour ago. Later, I’m going to give a shot at using the same program on the Windows computer and now that I know what to look for, I can probably get it to work there as well.
Most of the biofeedback games on the market until this year like those from Journey to Wild Divine use GSR biofeedback. GSR is short for Galvanic Skin Response which means that the sensors measure the electrical conductivity of your skin.
This new generation of brain games use EEG which is short for Electroencephalogram. The devices measure brain waves that are found at the surface of your scalp. Although this is a bit more promising of direct brain computer connection, there are still a lot of hurdles to overcome before we all are writing blog posts by brain waves.<br />

<img alt="" class="aligncenter" height="183" src="http://wakeup-world.com/wp-content/uploads/2012/01/A-CubeSat-in-Space.jpg" title="satelite" width="300" />
</div>
<div style="text-align: center;">
<br /></div>
<div style="text-align: center;">
<br /></div>
<div style="text-align: left;">
They call it the “Hackerspace Global Grid” and organizers say it would be made up of a network of low-orbiting satellites, all relatively small in size, which would be used to allow internet access that could not be controlled or blocked by any government censors.
The Hackerspace Global Grid, or HGG for short, would also integrate an array of base stations which would be located around the world.
The HGG is aimed at providing a way for activists and journalists to obtain access to the internet, <br />
<a name='more'></a>even when a repressive government has cut off access or censored the internet in one way or another.
While most people would think this is aimed at combating the authoritarian regimes in the Middle East being challenged by the so-called Arab Spring, this indeed could be quite useful in what some might consider the “free” nations like the United States and other Western nations.
With legislation similar to SOPA/PIPA being pushed around the world in the form of the Anti-Counterfeit Trade Agreement (ACTA), the danger of governments controlling the internet is growing.
The anti-censorship network would rely on low orbiting “cube” satellites which would be interconnected in a manner similar to the traditional internet.
This distributed network architecture allows for one satellite to be disabled without the entire network going down because the functions of the downed satellite would simply be re-routed to other units in the network.
While the developers of the project are excited for obvious reasons, critics and doubters believe that it will never happen.
However, some amateur HAM radio operators and others have already discovered methods to launch their cube satellites into orbit.
According to Nick Farr, a hacker and accountant working on the project, they will be using these methods along with new methods to get their satellites into low orbit.
Farr says this is a growing trend, telling TechNewsWorld, “What we’re seeing right now is a big explosion in people launching cube sats.”
While there is a lot of promise for the HGG, it is still in its infancy at this point. </div>
<div style="text-align: left;">
<br /></div>
<div style="text-align: center;">
<br /></div>
<div style="text-align: center;">

<br />
The organizers of the project still have to iron out how they will track the satellites in near-earth orbit from the ground because high orbiting satellites have a fixed position, making them much easier to track from the ground.
The problem with these low orbiting satellites is that they have variable positions and are fast moving, meaning that the window for locating one and then connecting is quite small indeed.
Currently they are focusing on establishing a network of base stations around the globe which will be used “to track various things, for example airplanes, satellites, weather information,” Armin Bauer, a lead hacker for the project said.
The organizers say that once enough stations are integrated into the network grid, it will be possible for the low-orbiting satellites to operate in a way similar to cellular networks.
As the satellite moves, the link would be passed from base station to base station, much like a cellular connection is passed from tower to tower.
I think this program has a lot of promise and I will be keeping tabs on it and hopefully we will see it go operational, in which case I would love to be a part of it as I’m sure many others worried about the viability of the future of the internet would be.

<img alt="" class="aligncenter" height="222" src="http://images.gizmag.com/gallery_lrg/nuiverse.png" title="universe" width="400" /> </div>
<div style="text-align: center;">
<br /></div>
Could this be the killer app for ultra-spec tablets? Microsoft Surface researcher David Brown is working on a marvelous space app that shows off not only the multi-touch power of Microsoft Surface, but also the computational grunt of the Samsung SUR40 on which it runs - not to mention the majesty of the solar system we live in and the Universe beyond.
<br />
<a name='more'></a>
View all
Of course, we're all well-acquainted with multi-touch demos by now, but the nuanced gestures in Brown's app, NUIverse, are something else. The name NUIverse is of course an anagram and play on the word universe, with the acronym for natural user interface incorporated. Clever: but nowhere near as clever as the app itself, which does indeed use the sort of familiar NUI gestures smartphone owners everywhere will be used to: grabs, twists, swipes and prods all work much as you'd expect.
But in fact not all the gestures could be considered natural - with some requiring the summoning of elaborate on-screen dials that can be used to control effects ranging from the very subtle - including the field of view of the camera, to the more fundamental - such as the passage of time. But writing about NUIs is like angling about acupuncture (if that's the expression). Probably the thing to do at this point is take a look at Brown demonstrating the app himself: <br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<iframe allowfullscreen='allowfullscreen' webkitallowfullscreen='webkitallowfullscreen' mozallowfullscreen='mozallowfullscreen' width='320' height='266' src='https://www.youtube.com/embed/qnnIzB-DBWc?feature=player_embedded' frameborder='0'></iframe></div>
<br />
<br />
As coffee tables go, this makes for rather a good one (if also expensive, at US$9,049 including the stand). But one has to wonder if this app will ever see a consumer release. Some of the effects (and the presence of Battlestar Galactica models) hint at heavier-duty applications such as video game development or perhaps even (one day) film special effects.
But we hope the app will see some sort of educational application. The power of the SUR40 is put to great use, rendering thousands of on-screen objects (all the data in the app is supplied by NASA) at a time - and turning on labels for them doesn't appear to appreciably slow it down. And the ability to set the solar system into motion with the speeding slowing and reversing of time means NUIverse is a wonderfully detailed and dynamic clockwork model of our corner of the cosmos. Observing an Earth-rise from the moon's dark side or watching from geosynchronous orbit the ballet of light and shadow play out on the Earth's surface (or at least digital recreations of these things) is compelling enough without need of spaceships.
Another video showing only the on-screen action of the app in use, can be seen below. There. Something the iPad doesn't do. Yet.

From what I heard today Samsung with its Flexible AMOLD OLED displays will soon outdate gorilla glass and be wearable 2013. We got a taste of Samsung’s amazing flexible<br />
<a name='more'></a> OLED displays at CES in 2011. According to some Samsung peeps the flexible OLED will be going commercial in 2013 (dates are unknown as of now). They also say screens can be bent so a user can wear them on their arm or rest them on their shirt. No immediate details but who needs gorilla glass anymore… Yes its unbreakable to a hammer! Check the videos below:

By now, people who use the Internet seriously, and even plenty who don’t, are aware of the arrest of six-foot-seven, 300-pound Kim Dotcom, an outsize figure in the business of facilitating Internet downloads.
The problem with his company, Megauploads, according to the US Justice Department and the FBI that carried out the arrest, is that his brainchild allowed users to traffic in "stolen" – copyrighted – entertainment on which no royalties had been paid.
</span><br />
<a name='more'></a><span style="color: white;">
In this article, I’ll comment on the arrest of Kim Dotcom and try to show how this one action is actually the beginning of an entirely new phase of what we may call the Internet Wars.
I’m not the first to notice this. As Kurt Nimmo and Alex Jones, of Infowars fame, pointed out in an article posted today entitled "The Great Internet Wars Have Begun," we wake up to an entirely new Internet era this weekend.
Yes, a war has been joined and human history shall never be the same. For one thing, the outcome is NOT certain – and the power elite that seeks to control and constrain the Internet may yet end up taking a step back – at least in these early rounds, anyway.
For another, the directed history that the Anglosphere power elite has been so clever at inculcating over the past century is gradually fading away. That’s perhaps an even more important point. The Dotcom arrest actually reinforces this observation, as I’ll try to show in a moment.
There is no doubt, in my view, that the elites practiced directed history in the 20th century, setting up wars and economic catastrophes designed to consolidate world government. But in the 21st century, with so many understanding and evaluating the mechanisms of the elites, this is a considerably harder trick to pull off.
The elites actually have a limited playbook when it comes to influencing the larger society, though that is not intended to downplay its power. The elites use what we call dominant social themes – fear-based promotions – that are designed to frighten middle classes into giving up wealth and power to specially prepared globalist institutions like the UN, IMF, etc.
The other "tools" in the toolkit include war and a pervasive societal matrix of sociopolitical, economic, religious and military elements. The matrix itself was seamless in the late 20th century – for most Western citizens anyway – and allowed the power elite to advance its fear-based promotions without fear of contradiction.

<div style="text-align: center;">
<span style="color: white;">Today, the Center for American Progress hosted a panel titled "Mind Wars: Brain Research and National Defense." CAP Senior Fellow Jonathan Moreno, Ph.D. gave a run down on his book and fellow panelist Jennifer Bard, a law professor at Texas Tech University, gave a legal analysis of advances in neuroscience research as applied to real life situations.
The most shocking comment came from panelist Paul Root Wolpe, Ph.D. when he said that it "is realistic that in ten to fifteen years, it could be possible to directly connect the human brain to the internet."</span></div>
<a name='more'></a><span style="color: white;"> He cited current research where neuroscientists are able to bypass lesions in the brain by connecting two sections of the brain by man made circuitry.
Despite such an earth shaking advancement being possibly a decade away, there exists no body of ethical oversight OR laws governing such research. The biggest sponsor of this type of research is the Federal Government, often funding scientific studies through the Defense Advanced Research Projects Agency, DARPA.
Techniques currently in development include functional Magnetic Resonance Imaging, or fMRI. It takes pictures of brain activity in real time and is being used to learn reactions of the brain to figure out if someone is lying, their sexual orientation, if they have racist tendencies, if they are extroverted, and countless other things. It is the closest that we have come to "mind reading."
DARPA is funding an "Enhanced Human Performance" project. Augmenting cognition, or increasing brain function, is one of the goals of this project. This can be accomplished by inserting a chip in a soldier's brain and increasing the bandwidth of brain activity.
The drug Modanafil has also been developed and can keep people awake for days at a time without the need for sleep or calories. This has already been made available in the private sector under the name Provigil.
This barely scratches the surface of an emerging issue about which the Center for American Progress hopes to begin a public discussion. The potential implications of this issue on civil liberties is enormous. It warrants much scrutiny until acceptable legal and ethical standards are created. There should also be a balance between using these new advances for national defense and using it in the private sector where it can be used to improve the lives of everyday Americans.

<span style="color: white;"><strong>'The Matrix'</strong> is a step closer to reality; Neuroscientists break code on sight
From: physorg.com
In the sci-fi movie "The Matrix," a cable running from a computer into Neo's brain writes in visual perceptions, and Neo's brain can manipulate the computer-created world. In reality, scientists cannot interact directly with the brain because they do not understand enough about how it codes and decodes information.
Image: Neurons in a purely visual brain region called the inferotemporal (IT) cortex respond selectively to different images. As pictures were randomly presented to the monkey during specific intervals (top), neurons at different sites in IT produce distinct patterns of activity to each picture (bottom). For example, neurons at site 1 favor the toy and the yam, while neurons at site 3 prefer the monkey face and the cat. Image courtesy / Poggio/DiCarlo labs
Now, neuroscientists in the McGovern Institute at MIT have been able to decipher a part of the code involved in recognizing visual objects. Practically speaking, computer algorithms used in artificial vision systems might benefit from mimicking these newly uncovered codes.
The study, a collaboration between James DiCarlo's and Tomaso Poggio's labs, appears in the Nov. 4 issue of Science.
"We want to know how the brain works to create intelligence," said Poggio, the Eugene McDermott Professor in Brain Sciences and Human Behavior. "Our ability to recognize objects in the visual world is among the most complex problems the brain must solve. Computationally, it is much harder than reasoning." Yet we take it for granted because it appears to happen automatically and almost unconsciously.
"This work enhances our understanding of how the brain encodes visual information in a useful format for brain regions involved in action, planning and memory," said DiCarlo, an assistant professor of neuroscience.
In a fraction of a second, visual input about an object runs from the retina through increasingly higher levels of the visual stream, continuously reformatting the information until it reaches the highest purely visual level, the inferotemporal (IT) cortex. The IT cortex identifies and categorizes the object and sends that information to other brain regions.
To explore how the IT cortex formats that output, the researchers trained monkeys to recognize different objects grouped into categories, such as faces, toys and vehicles. The images appeared in different sizes and positions in the visual field. Recording the activity of hundreds of IT neurons produced a large database of IT neural patterns generated in response to each object under many different conditions.
Then, the researchers used a computer algorithm, called a classifier, to decipher the code. The classifier was used to associate each object -- say, a monkey's face -- with a particular pattern of neural signals, effectively decoding neural activity. Remarkably, the classifier found that just a split second's worth of the neural signal contained specific enough information to identity and categorize the object, even at positions and sizes the classifier had not previously "seen."
It was quite surprising that so few IT neurons (several hundred out of millions) for such a short period of time contained so much precise information. "If we could record a larger population of neurons simultaneously, we might find even more robust codes hidden in the neural patterns and extract even fuller information," Poggio said.

<span style="color: white;"><img alt="" class="aligncenter" height="194" src="https://encrypted-tbn1.google.com/images?q=tbn:ANd9GcRU2efUlCuhWldNCfr4bI3R8N0jFGi2ndNSi2jj2KKTIiBIgd-f" title="space" width="259" /> </span></div>
<span style="color: white;"><br /></span>
<span style="color: white;">What if Neanderthals, who bit the dust just 28,000 years ago, had instead wised up and were now living next door? Or what if, during all these millennia that humans have been evolving, some unrelated creature had evolved cognitive and technological prowess in keeping with our own?</span><br />
<a name='more'></a><span style="color: white;">Another scenario: what if humans had split into two separate species — the original gangsters, and a successful evolutionary offshoot?
These are all perfectly reasonable histories of the world that would have resulted in two advanced species of Earthlings living side-by-side today. They’re just not the histories that happen to have happened.
But what if they had? Would we break bread with our brainy cohabitants or be locked in a constant battle for supremacy?</span><br />
<div style="text-align: center;">
<span style="color: white;">
<img alt="" class="alignleft" height="279" src="https://encrypted-tbn1.google.com/images?q=tbn:ANd9GcSyGYpfZYG_JalWtS9xu_m2oJeDmHhyMvYaEyv3QOXARU9mrpsq" title="alien" width="181" /></span></div>
<span style="color: white;"><br /></span>
<span style="color: white;">Oh, them – just ignore them
In this hypothetical world, there would be three possible relationships between humans and "others," said William Harcourt-Smith, a paleoanthropologist at the American Museum of Natural History. The most likely one is that competition for resources would cause us to fight, constantly.
"Given knowledge of how humans behave within their species — the endless intertribal conflicts and wars that have sadly gone on for many thousands of years — I think that whenever resources become an issue, or competing ideologies become an issue, you get conflict," Harcourt-Smith said. If one of the species was slightly cleverer or stronger or developed better technology than the other, the former would eventually decimate the latter, reminiscent of Humans vs. Neanderthals.
Alternatively: If, after tens of thousands of years of clashes between Humans and Others, no one had come out on top, the two species might have gradually drifted toward equilibrium, either by populating geographically separate regions of the globe or by adapting to require different resources, Harcourt-Smith said. Others might have developed an appetite solely for fish, for instance, while Humans might have specialized in animal husbandry, and come to find fish disgusting.
In either of those cases — if we lived in different regions or utilized different resources — Humans and Others would have developed cultural systems in which we were taught to avoid one another. That’s what other species do under the same circumstances. "As long as there isn’t competition, species just ignore each other," he said. "Two monkeys living in the same tree, for example — if they’re not going after the same resources, they don’t interact."</span>

<div style="text-align: center;">

<br />
<span style="color: white;"> February 14, 2025 - Today is the release of the first home computer with the new 4 THz microprocessor, currently the highest performing processor available. Several analysts have doubted of the need of the 4THz processor for the home market, but the pre-sale for the last couple of weeks look positive according to the manufacturer.</span><br />
<a name='more'></a><span style="color: white;">
The computer has the 100TB memory drive that became standard about 5 years ago, basically because the lack of interest in more storage for home computers due to cloud hosting. It's nice that they have included 1,000 movies in the package but as you can guess they are not the latest releases.
It has 512 GB RAM memory, the size of the box is 10.3" x 7.9" x 1.2" (WxDxH) and it is of course compatible with all the wireless screens that you have at home. The introduction price is set to US$ 399.
Argument: According to Moore's Law the number of transistors that could be placed on a computer chip would double every 18 months which has been the case since the 1970s. Gordon Moore has though revised his law since then which could give us a microprocessor of 4 THz by 2025.
Questions: Will there be need for more than 100 TB storage memory for the home market? How far will it go with cloud hosting? What else can drive the development of home computers than moving images, as in movies and games? </span>

<span style="color: white;">Google has publicly unveiled new photos and the first video from the real view of their augmented reality glasses prototype. The images show what the wearer sees while reading a newspaper, catching a football in the backyard and helping a smiling child play on the jungle gym.</span><br />

Such views don’t necessarily represent anything people haven’t seen before with head-mounted portable cameras. But they do hint at how Google Glasses could enable many people beyond geeky life-casters to capture a diverse array of moments in their lives — the video shows the bouncy viewpoint of the Google Glasses wearer doing flips on a trampoline.</span></div>

The Internet search giant has yet to show off real images or photos of how the glasses could seamlessly integrate virtual information with what a person sees in the real world. Its earlier unveiling of “Project Glass” included a concept video that imagined a wearer getting social calendar reminders and map directions in his field of view.</span></div>

Still, many members of the public still seem enthusiastic about just having a pair of glasses with a small camera attached. One of the top comments on the YouTube video of the trampoline jumping simply stated “Shut up and take my money!”</span></div>

The most popular comment of all had a perhaps tongue-in-cheek suggestion for using the Google Glasses — “Good for POV [point-of-view] porn.”</span><br />
