Most of your body is now upgradable by Technology

As you see from the blogs here, nanotechnology, neuroscience, electronics and hi-tech materials are already replacing whole limbs and organs in a fast developing field of science


By the end of the year researchers will try out the first bionic eye implant in the UK hoping to help a blind patient see for the first time.
Check out this cool BBC news interactive page for a rundown of what's going on/

We've been cramming more intricate engineering into our bodies than you might think. For more on this fascinating subject, check out The Bionic Body Shop

 Neuroscientists at the University of California, Berkeley working with Champalimaud Center in Portugal have demonstrated that the brain is more flexible and trainable than previously thought.
Their new study, published March 4 in the advanced online publication of the journal Nature, shows that through a process called plasticity, parts of the brain can be trained to do something they normally do not do; like controlling a prosthetic limb for example.


The new study advances work by researchers who have been studying the brain circuits used in natural movement in order to mimic them for the development of prosthetic devices.
"What we hope is that our new insights into the brain's wiring will lead to a wider range of better prostheses that feel as close to natural as possible," said Jose Carmena, UC Berkeley associate professor of electrical engineering, cognitive science and neuroscience.

The Earth has a roughly 12 percent chance of experiencing an enormous megaflare erupting from the sun in the next decade, according to space physicist Pete Riley, senior scientist at Predictive Science in San Diego, California, writing n Space Weather on Feb. 23.

This event could potentially cause trillions of dollars’ worth of damage and take up to a decade to recover from, according to a 2008 report from the National Research Council.

The last gigantic solar storm, known as the Carrington Event, occurred more than 150 years ago and was the most powerful such event in recorded history.

Earth’s sun goes through an 11-year cycle of increased and decreased activity. During solar maximum, it’s dotted with many sunspots and enormous magnetic whirlwinds erupt from its surface. Occasionally, these flares burst outward from the sun, spewing a mass of charged particles out into space. (Wired.com)







Project HAARP. Brollies will be useless against this threat

US Military working on Weather control?
HAARP  began in 1990 and is funded by the Office of Naval Research jointly with the Air Force Research Laboratory.  Its official purpose is to "analyze the ionosphere and investigate the potential for developing ionospheric enhancement technology for radio communications and surveillance purposes."

This invention has a phenomenal variety of possible ramifications and potential future developments. As alluded to earlier, missile or aircraft destruction, deflection, or confusion could result. particularly when relativistic particles are employed. Also. large regions of the atmosphere could be lifted to an unexpectedly high altitude so that missiles encounter unexpected and unplanned drag forces with resultant destruction or deflection of same. Weather modification is possible by, for example, altering upper atmosphere wind patterns or altering solar absorption patterns by constructing one or more plumes of atmospheric particles which will act as a lens or focusing device.

Neural implants to replace damaged sensory cells

Biocompatible chips made of graphene.


(Nanowerk News) In the future, neural implants could replace destroyed sensory cells in the eye or ear – a dream come true for humanity.
One of the greatest challenges yet to be addressed is designing the interface between medical technology and human tissue.
In order to overcome the limitations of existing models, scientists from Forschungszentrum Juelich and eleven other institutions involved in the NeuroCare project, which kicked off on 1 March 2012, will develop novel biointerfaces made of carbon.
If you are a regular visitor to this blog, you will know nanoparticles can be absorbed by the body through the skin or via ingestion as part of foods where nanotechnology is part of of the production process.
You will also have read about nanoscale wireless communication.

It is a commonly held rule that technologies converge and it takes little imagination to consider the dangers of neuro and nanotechnology convergence.

The world of Alister Cloud is one possible future where these convergences have already taken place.
Set in a society where  governments depend upon  ruthless Private Military Companies willing to use any technological advantage to retain contracts and control, the book explores the darker side of today's emerging technologies.
At the end of 2011, researchers from
Forschungszentrum Jülich and Technische Universität München
grew cardiac cells on a graphene transistor.

The Greeks, the riots, the dog.


One committed protester has been at the front line of Greece protests for years.
The dog, thought to be a stray called Loukanikos, or Sausage, has become both a symbol and inspiration for Greek protesters, showing no fear, always in the action, constantly barking down police.

Anonymous take down Interpol Website




The Guardian Reports the following
"Interpol's website appears to have been the victim of a cyber-attack after the international police agency announced the arrests of 25 suspected members of the hacking activist group Anonymous in Europe and South America.
The website went down briefly on Tuesday as supporters of Anonymous made online claims that it had been targeted following the arrests in Argentina, Chile, Colombia and Spain. It was quickly back up and running but was loading slowly."

Get involved in the Public Consultation on Neurotechnology

From Nuffield Council on Bioethics website

Recent developments in Neurology, computing and nanotechnology have led to methods of enabling the brain to directly control computers and thereby machinery; computers that can translate or  'read' thoughts, methods of influencing our thoughts and emotions.

As a result, the Nuffield Council on Bioethics has launched a public consultation on the ethics of the technology. Download the consultation doc and give your feedback. You don't need to be an academic or researcher to tell them what you think of the emerging technologies and if you would use them should the need or opportunity arise. Go on, get involved. You can download the consultation paper from the link on the Nuffield Council on Bioethics page

Professor Baldwin from the University of York is leading the study. According to the BBC News Website Professor Baldwin said "Intervening in the brain has always raised both hopes and fears in equal measure.
"Hopes of curing terrible diseases, and fears about the consequences of trying to enhance human capability beyond what is normally possible.
"These challenge us to think carefully about fundamental questions to do with the brain: what makes us human, what makes us an individual, and how and why do we think and behave in the way we do."

Wi-fi on an atomic scale - the perfect fit

ScienceDaily (Feb. 28, 2012) — We know since the dawn of modern physics that although events in our everyday life can be described by classical physics, the interaction of light and matter is down deep governed by the laws of quantum mechanics. Despite this century-old wisdom, accessing truly quantum mechanical situations remains nontrivial, fascinating and noteworthy even in the laboratory. Recently, interest in this area has been boosted beyond academic curiosity because of the potential for more efficient and novel forms of information processing.

Alister's SoftMachine outfit is a morphing, colour changing outfit that receives instructions from both Alister and the world's most powerful supercomputer. The wireless function is built into the nanomaterial of the outfit.
Here's a rehash exercise I undertook of the Science Daily article  just to help me understand what had been achieved


 "A single atom or molecule acts as a quantum bit processing signals delivered via single photons. 
It is possible to set up a situation where single molecules can be detected and single photons generated. 
The problem is putting together a simple one on one interaction because billions of photons per second are usually impinged on a molecule to obtain a signal from it.
First off, you  would have to find a suitable source of single photons, which have the proper frequency and bandwidth. Although lasers come in different colours and specifications, something that fires single photons can't be bought at Maplins or Radio Shack
One common way to get around this difficulty in atomic physics is to build a cavity around the atom so that a photon remains trapped for long enough times to increase the chances of a 1-1 interaction. 
 And it's been done. Connecting a single flying photon with a single molecule. 
So a team of scientists (at ETH Zurich and Max Planck Institute for the Science of Light in Erlangen) led by Professor Vahid Sandoghdar made something that spits out single photons. 
How? Well they cheated a little by using a photon release event that happens naturally. When an atom or molecule absorbs a photon it makes a transition to a so-called excited state. After a few nanoseconds (one thousand millionth of a second) this state decays to its initial ground state and emits exactly one photon. 
So the group used two samples of fluorescent molecules embedded in organic crystals and cooled them to about 1.5 K (-272 °C). Single molecules in each sample were detected by a combination of spectral and spatial selection.
To generate single photons, a single molecule was excited in the “source” sample and when the excited state of the molecule decayed, the emitted photons were collected and tightly focused onto the “target” sample at a distance of a few meters. 
The team had to (1) make sure the photon and the molecule had the same frequency; and (2)  get the single photons to interact with the target molecule in an efficient manner. 
Not that easy when the focus of a light beam cannot be smaller than a few hundred nanometers; while a molecule is about one nanometer in size (100,000 times smaller than the diameter of a human hair); which would lead to most of the incoming light (photons) going around the molecule, i.e. without them seeing each other. 
Here's the 'but';  if the incoming photons are resonant with the quantum mechanical transition of the molecule, the molecule acts more like a prefect little catchers glove to the area of the focused light and grabs the light waves in its vicinity. 
The experimental work was performed at ETH Zurich before the group of Prof. Sandoghdar moved to the newly founded Max Planck Institute for the Science of Light in Erlangen in 2011."

Nanomaterials and the 'do anything you want' outfit.

ScienceDaily (Feb. 24, 2012) — Researchers at the NanoScience Center of the University of Jyväskylä, Finland, and at Harvard University, US, have discovered a novel way to make nanomaterials. Computer simulations predict that long and narrow graphene nanoribbons can be rolled into carbon nanotubes by means of twisting.  Being classical in origin, the mechanism is robust and valid on the macro-, micro- and nanoscale.
The mechanism also enables experimental control, which has earlier been impossible. The mechanism can be used to make various kinds of novel carbon nanotubes, to encapsulate molecules insides the tubes, or to make tubules from ribbons made out of other planar nanomaterials.
For the past twenty years, carbon nanotubes have been described as "rolled-up graphenes," even though no-one ever really did the rolling. Today, nanotubes, along with many other nanomaterials, are made by atom-by-atom growth.
The results were published in Physical Review B. The research used the computer resources of the Finnish IT Centre for Science (CSC), based in Espoo.

Part Two.
Add to this a couple of other developments reported here in the blog. (a) atom sized transistors and (b) technologies powered by touch and, boom: a computer woven into the nanomaterials of your clothing and powered by the kinetic and thermal energy produced by your movement.
Elsewhere here you'll find posts on brain-machine interfaces. It is feasible to consider a material containing nanotechnology components with different functions; one of which will be to allow manipulation of the different technologies in the outfit by thought alone.
