Organic Transistor Paves Way for New Generations of Neuro-Inspired Computers

organic transistor

For the first time, CNRS(1) and CEA(2) researchers have developed a transistor that can mimic the main functionalities of a synapse(3). This organic transistor, based on pentacene(4) and gold nanoparticles and known as a NOMFET (Nanoparticle Organic Memory Field-Effect Transistor), has opened the way to new generations of neuro-inspired computers, capable of responding in a manner similar to the nervous system.

The study is published in the 22 January 2010 issue of the journal Advanced Functional Materials.

In the development of new information processing strategies, one approach consists in mimicking the way biological systems such as neuron networks operate to produce electronic circuits with new features. In the nervous system, a synapse is the junction between two neurons, enabling the transmission of electric messages from one neuron to another and the adaptation of the message as a function of the nature of the incoming signal (plasticity). For example, if the synapse receives very closely packed pulses of incoming signals, it will transmit a more intense action potential. Conversely, if the pulses are spaced farther apart, the action potential will be weaker.

It is this plasticity that the researchers have succeeding in mimicking with the NOMFET.

Re-skinning the city – the dark side of augmented reality

who framed roger rabbit

Years ago, I had an idea for a futuristic pair of goggles that visually transformed homeless people into lovable animated cartoon characters. Instead of being confronted by the conscience-pricking sight of an abandoned heroin addict shivering themselves to sleep in a shop doorway, the rich city-dweller wearing the goggles would see Daffy Duck snoozing dreamily in a hammock. London would be transformed into something out of Who Framed Roger Rabbit.

What’s more, the goggles could be adapted to suit whichever level of poverty you wanted to ignore: by simply twisting a dial, you could replace not just the homeless but anyone who receives benefits, or wears cheap clothes, or has a regional accent, or watches ITV, and so on, right up the scale until it had obliterated all but the most grandiose royals.

At the time this seemed like a sick, far-off fantasy. By 2013, it’ll be just another customisable application you can download to your iBlinkers for 49p, alongside one that turns your friends into supermodels and your enemies into dormice.

Apple and Control Machines

apple: come see our latest restriction

In the days before the new Apple tablet was announced the anti-DRM group Defective by Design dubbed Apple’s announcement event the “Come see our latest restriction” event. Since then, there’s been a lot of chatter about the various limitations of the device – DRM, or otherwise.

I think some of these limitations could be important for the future of computing and media.

Limitations could be a feature – keeping people focused on reading. Perhaps we shouldn’t be thinking of this as a laptop or netbook alternative at all, but as an text reader and video player. Having a limited multitasking abilities and a lack of Flash might be a means to limit our level of distraction from e-mail and instant messaging. Stan Schroeder wrote for Mashable:

Then, there’s multi-tasking. Nearly everyone I’ve talked to thinks this is a huge deal-breaker, but I think it makes sense. Although Steve Jobs was trying hard to prove to us that the iPad is a computer, it isn’t. Just like the iPod and the iPhone, its main purpose is to give the users an easy way to consume certain types of digital content. After music (iPod) and mobile applications (iPhone) comes iPad with video, photos, e-books, e-magazines, games. Apple doesn’t really want you to do complex photo editing on the iPad; you’ve got your Mac or PC for that. Apple wants you to touch a button, and start consuming content (preferably paying a couple of dollars for it).

Finally, the camera. Yes, it would be nice to have video chat. But once again, Apple wants you to do that on a Mac. If you want to snap photos, you should do it on the iPhone — you’re carrying it with you all the time, anyway. Once again, it becomes clear that Apple doesn’t want to sell devices that can do everything; they want to find the best form factor to consume some types of digital content, and then focus on them. If you look at it, you can do pretty much everything on your personal computer; by that philosophy, you don’t need anything else besides a laptop. And yet, you’ve now got smartphones and e-readers selling very well. Could it be that one powerful device is not as good as several less powerful, but more focused ones?

If that’s the case, and the iPad is just another consumer device and a paradigm, then it’s no big deal.

But if they’re letting users instal everything from the iPhone app store, then are they really designing useful limitations to keep the device focused? You can install apps that do just about anything, not just consume media. And the keyboard extension explicitly allows two-way media interaction.

Ultimately the lack of Flash or multitasking or a web cam seem trivial to me. They’re just features that may or may not be able to make or break the latest in consumer technology. And that’s just not important. But there’s a scarier possibility – that Apple is slowing easing its customers into an app-store centric world, where every app that runs on their platform on a “legitimate” (non-“jailbroken”) device has to pass their gates. It may sound conspiratorial, but I worry that Apple is trying to migrate their closed device paradigm from the mobile world (where that sort of thing is already pretty common) to the desktop world (where that’s unheard of). It’s strange that years after Trusted Computing became an information liberty concern, it’s been Apple, not Microsoft, leading the way to a more restrictive computing environment.

Peter Kirn at Create Digital Music has an extensive post considering the potential problems of the “closed Apple” world:

Apple already has a dangerously dominant position in the consumption of music and mobile software, and their iTunes-device link ensures that content goes through their store, their conduit, and ultimately their control. This means that developers are limited in what they can create for the device when it comes to media – a streaming Last.fm app is okay, but an independent music store (like Amazon MP3 on Android) is not. Now, you can add to that Apple dominating book distribution. At a time when we have an opportunity to promote independent e-book publishing, the iPad is accompanied by launch deals from major traditional publishers. What does that mean for independent writers and content? […]

Apple threatens to split computing into two markets, one for “traditional,” “real” computers, and another for passive consumption devices that try to play games without physical controls and let you read books, watch movies, play music, and run apps so long as you’re willing to go through the conduit of a single company.

And, of course, this wouldn’t be worth my breath if not for my real concern: what if Apple actually succeeds? What if competitors follow this broken path, or fail to offer strong alternatives? The iPad today is a heck of a lot slicker than alternatives. It’s bad news for Linux, Windows, and Android, none of which have really workable competitors yet. It’s especially bad for Linux, in fact, which had a real chance to make its mark on mobile devices.

Timothy Blee makes the case that restricted computing will lose out in the market. I’m not so optimistic.

On not-so-dark note, I was disappointed at how uninnovative the iPad is. It’s just a big iPod touch, or a really crippled tablet pc. It seems like it could be an interesting musical insturment (a nice platform for RJDJ, for instance) It doesn’t seem like as much of a game changer as something like this:

microsoft courier

It’s unusual for Microsoft to out innovate Apple (or rather, to beat them to stealing good ideas), but their Courier seems to do just that. Of course, it’s vaporware right now, and could continue to be so, just like its abandoned predecessor the OLPC2:

Twitter works on technology to evade censors in China and Iran

iran internet cafe

Twitter, the internet social network, is developing technology it hopes will prevent the Chinese and Iranian governments being able to censor its users. […]

Mr Williams, speaking at the World Economic Forum, said he admired Google for its decision last month to confront China over censorship and cyberattacks on its service, but said Twitter was too small to take a similar stand.

“We are partially blocked in China and other places and we were in Iran as well,” he said. “The most productive way to fight that is not by trying to engage China and other governments whose very being is against what we are about. I am hopeful there are technological ways around these barriers.”

Mr Williams said Twitter had an advantage in evading government censors through operating as a network of internet and mobile applications, rather than as a single website. “Twitter is a network that is accessed in thousands of ways.”

‘Cyber Genome Project’ kicked off by DARPA

Applecart-bothering Pentagon boffinry bureau DARPA is at it again. This time, the military scientists want to establish a “Cyber Genome” project which will allow any digital artifact – a document, a piece of malware – to be probed to its very origins. […]

Or in other words, any code you write, perhaps even any document you create, might one day be traceable back to you – just as your DNA could be if found at a crime scene, and just as it used to be possible to identify radio operators even on encrypted channels by the distinctive “fist” with which they operated their Morse keys. Or something like that, anyway.

Augmented Reality in a Contact Lens

augmented reality contacts

These visions (if I may) might seem far-fetched, but a contact lens with simple built-in electronics is already within reach; in fact, my students and I are already producing such devices in small numbers in my laboratory at the University of Washington, in Seattle [see sidebar, “A Twinkle in the Eye”]. These lenses don’t give us the vision of an eagle or the benefit of running subtitles on our surroundings yet. But we have built a lens with one LED, which we’ve powered wirelessly with RF. What we’ve done so far barely hints at what will soon be possible with this technology. […]

These lenses don’t need to be very complex to be useful. Even a lens with a single pixel could aid people with impaired hearing or be incorporated as an indicator into computer games. With more colors and resolution, the repertoire could be expanded to include displaying text, translating speech into captions in real time, or offering visual cues from a navigation system. With basic image processing and Internet access, a contact-lens display could unlock whole new worlds of visual information, unfettered by the constraints of a physical display.

Guardian Launches Search Engine for Government Data from Around the World

world government data

The UK Guardian, ostensibly a newspaper but a major proponent for opening data held by governments to use by outside software developers, has launched some software of its own: a search engine that unearths datasets and pathways to data sets provided by governments around the world. World Government Data Search is now live.

Yesterday the UK government released its new data site, data.gov.uk, to rave reviews (including ours). The new Guardian search engine searches across the UK, US, New Zealand and Australian governments’ data sites. The company also offered up a gallery of the 10 best visualizations and mash-ups built on top of government data like this.

Augmented reality – application examples video

This comes from MetaverseOne, creator of the augmented reality medical app mentioned here before.

If you’re interested in this sort of thing, be sure to check out The Headmap Manifesto (PDF) – it’s from the early 00s, but still relevant today. (I just host it here, I had absolutely nothing to do with Headmap).

Sound Generator Could Kill Humans at Ten Meters

Thunder Generator

The Thunder Generator uses mixture of liquefied petroleum, cooking gas, and air to create explosions, which in return generate shock waves capable of stunning people from 30 to 100 meters away. At that range, the weapon is absolutely harmless, making people run in panic when they feel the sonic blast hitting their bodies. However, at less than ten meters, the Thunder Generator could either cause permanent damage or kill any person.

Chemical computer that mimics neurons to be created

chemical computer

A promising push toward a novel, biologically-inspired “chemical computer” has begun as part of an international collaboration.

The “wet computer” incorporates several recently discovered properties of chemical systems that can be hijacked to engineer computing power. […]

What distinguishes the current project is that it will make use of stable “cells” featuring a coating that forms spontaneously, similar to the walls of our own cells, and uses chemistry to accomplish the signal processing similar to that of our own neurons.

The goal is not to make a better computer than conventional ones, said project collaborator Klaus-Peter Zauner of the University of Southampton, but rather to be able to compute in new environments.

“The type of wet information technology we are working towards will not find its near-term application in running business software,” Dr Zauner told BBC News.

“But it will open up application domains where current IT does not offer any solutions – controlling molecular robots, fine-grained control of chemical assembly, and intelligent drugs that process the chemical signals of the human body and act according to the local biochemical state of the cell.”
