Bionic implants raise ethical questions

Australian researchers trying to regrow damaged spinal cords with tiny bionic implants are seeing for the first time what’s happening at the nanoscale.

Meanwhile, philosophers working alongside the researchers say it’s time to find out more about how the public feels about such bionic research, which in some cases is being used to enhance human memory, physical abilities and perception.

Researchers told the International Conference On Nanoscience and Nanotechnology in Melbourne this week that they are working towards repairing damaged tissue by extending bionic ear technology.

The bionics program at the ARC Centre of Excellence for Electromaterials Science is developing flexible conducting polymers that can be implanted in the body and interact directly with living cells.

The polymers can deliver electrical, mechanical or chemical messages to cells, such as nerve and muscle cells, and receive signals back.

Dr Michael Higgins and colleagues are packing the polymers with cell growth factors and using them to encourage nerve cells to grow in the lab.

When an electrical stimulus is applied to the polymers they pulsate and slowly release the chemicals.

Both the mechanical movement itself and the chemicals it releases can help cells to grow but it’s not yet clear how exactly this works.

To explore this, Higgins has been using an atomic force microscope to take a nanoscale look at what’s happening.

This means he can look in unprecedented detail at the real-time interaction between the polymer and the proteins and receptors on the surface of nerve cell to understand how best to make them communicate with each other.

Higgins says the polymers could be used as a generic interface for a range of bionic applications.

What does the public think?

Philosophers Dr Rene Kyle and Professor Susan Dodds work in the same research centre at the University of Wollongong and also presented at the nanotechnology conference.

Their role is to look at the social and ethical implications of bionic research.

They say it is important for scientific researchers in bionics to start talking to the public to find out what they think of this technology and how it might be applied.

“Obviously there are benefits of the technology,” says Kyle. “But if people feel excluded they are less likely to take the technology up.”

Kyle says past experience with the cochlear implant showed how important it was to talk to groups who are most likely to be affected by the technology, including people with disabilities and their carers.

“The deaf community as a whole was really angry that it wasn’t involved as the research and development progressed,” she says.

Dodds says it’s an issue of respect.

“There’s a recognition that this technology does shape the world in which people live.”

Discrimination?

Kyle and Dodds say bionics could exacerbate existing discrimination against people with disabilities, especially when only some will be able to afford it, and could affect their relationships in the world.

“It’s not just a technical issue but it’s one that has social dimensions,” says Dodds.

Looking into the future, she ponders the issues that bionics aimed at enhancing memory might bring.

“What will it mean beyond being able to do well in tests?” she asks.

“Imagine a world in which you, but not your partner, could remember every conversation you’ve ever had,” says Dodds. “It could have a bizarre effect on our social relations.”

Worth the money?

Bionics aimed at repairing or enhancing human bodies also raises the ethical issue of spending scant public health resources on select disabilities.

Higgins and colleagues say they welcome Dodds and Kyle’s thought-provoking comments.

“It’s good to have a deeper understanding about what you’re doing rather than just a technical aspect of it,” says Higgins.

    “Forskarnas” kränkningar av FN:s deklaration om de Mänskliga Rättigheterna med MIND CONTROL implantat i den mänskliga hjärnan!!!

    I Sverige utvecklas syntetisk telepati, en kommunikationsteknik byggd på tankar, inte tal.

    Dator-hjärna-gränssnitt i nanostorlek kan nu injiceras i människan av internationella forsknings syndikat på svenska sjukhus. Syntetisk telepati utvecklas med de nya dator-hjärna-gränssnitten, teknologins utveckling sker under brutala forskarövergrepp på oskyldiga människor. Det tar flera år av programutveckling för det nya multimediaspråket mellan människa och maskin. Tankekommunikationen inkluderar avbildning och kommunikation med människans sinnen (perception).

    Människan håller med nanoteknologin och denna forskning på att förvandlas till en multimediaapplikation. Forskardatorer kan via nanoimplantaten med lögndetektor-programvaror och multimediateknik i cloud/grid computing, det så kallade ”molnet” avkoda och läsa människans tankar och sinnen.

    Is an Artificial Brain possible at all ? Are motivation, fear, emotions, instincts, and all other ’special features’ we humans possess required and why ? What about the consciousness and subconscious ? Would an Artificial Brain work without the possibility to lie and on what base should stuff like attention and intuition be implemented ? Are neural networks the only answer or are other options preferable ?

    I stumbled onto your site, and think you did an fantastic job. I am very motivated as a Ti and human rights activist. There is power in numbers and making contact and coordinating with others in our situation is important. I have a Web site http://www.unwittingvictim.com In my case I am very grounded, with a stable foundation, although the perpetrators are short circuiting my short term memory and stopping my free ability to think. I am in communication with other well grounded group leaders in the US on a daily basis. We could possibly combine our efforts on a project that we find mutually beneficial and motivating. We need to ensure we follow through with any of our efforts, while combining our individual efforts to form a stronger and more powerful whole. We are all adversely affected, mind bending is the only word that I can think of that conveys what our, the Ti community’s, knowledge base suffers through. We need join forces to ensure we are a force to be reckoned with on a project of our choosing. We would be a group of Ti’s who have awareness foundation, understand the gravity of the harm and hardship, are well grounded, and are motivated.

  6. There is an urgent need for thorough public debate and consultation before these devices are let loose on society.

    Great website! I think there are many valuable information and advices here. Along the same line, I came across the following website which I found interesting. Traditionally, personality tests such as MBTI have been used as career aptitude test. However, these tests have a very limited scope as they ignore many important factors such as person’s skills, values, and interests.

    There have been many advancements in the area of career aptitude testing. Usage of artificial intelligence to evaluate suitability of a job for a person is one of the these techniques. You can take a complete version of the MBTI personality test plus many others such as memory, IQ, problem solving, and patience tests in OptYourLife. This website’s expert system tries to find the most suitable career path for you using neural network. Moreover, salary of different careers will be considered in the final analysis to provide a more insightful advice for you // Stacy L.
