A Bad Memory Erasing Pill

The February issue of Wired magazine contained an article about an interesting medical breakthrough related to memory. Scientists working on the development of a pill that can erase bad memories have achieved success in laboratory rats.

Bad memories, a thing of the past?

It is a long and detailed article, but I will try to summarize it in a few sentences. Memories are stored in different parts of the brian, emotions in one part, visuals in another etc. In order to remember something a sort of chain must be formed that link the separate parts of the memory, a chain formed by protein. If you can block the protein you can block access to the memory.

Scientists have been experimenting for decades to try and find a compound that can do this, and recently seem to have found one that works on rats. The experiment is relatively simple, the rats are exposed to series that they learn to recognize, an example might be a series of musical notes followed by a painful electric shock. As soon as the rats hear the first note in the series they get scared and agitated. Administer the compound and the association is lost, you can play the series and the rats no longer remember the consequences until BANG, the shock arrives.

Cruel but bearing important consequences, if the links in the chain can be broken then the memory is not cancelled but the individual no longer has access to it.

As I said above different parts of the memory are stored in different places, so the hope is that different compounds will be able to delete different aspects of painful memories. One might close access to the memory of the scent of an ex girlfriend who left you for your best mate, or the pain experienced in an accident, or the vision of your dog jumping out of your third floor bedroom window while chasing a ball that you accidentally threw too hard for him to catch, or other such traumas.

Talk is of selected memory loss by pill, but of course this is far in the future if ever at all, but the very prospect raises some interesting ethical dilemmas. We are who we are by experience. I don’t play with knives; I have a scar with 7 stitches in my hand to remind me why, but even without it the memory of a Christmas Eve trip to Wythenshawe Hospital lingers on.

And having seen various governments conduct more than questionable research on their own populations (and others) and I am not just talking about despot regimes but the very birth states of democracy themselves as this apology given by President Obama demonstrates, I sincerely question the ethics behind such a development.

So the question is this, are we seeing a great medical and technological breakthrough, a leap in human advancement, or the creation of another dangerous tool once it gets into the wrong hands?

The State of the Blogosphere

Technocrati.com have recently published their State of the Bolgosphere 2011 report and it raises some interesting questions. The report is based upon a survey of 4114 bloggers around the world, and presents various statistics in easily readable graph format explaining who blogs and their stated reasons why and purposes.

I am one of the 30% over 44 year olds, with the majority being considerably younger than me and much more experienced. A small percentage treat blogging as their job, make an income from their posts or run a blog for their own business or employer. The vast majority do it as a hobby, in the main to express their expertise or interests. A major sector say that they just blog in order to speak their mind freely.
I am most interested in the professional category, and I in fact find myself somewhere within that group. I am not however paid to promote something, but to provoke discussion about the ethical implications and responsibility issues brought about by technological development, and one of my tools is blogging. My employer is also a non-profit research foundation, so the aim of making money is out of the equation.

Blogging is generally perceived as a pier to pier action, and the report cited above demonstrates that people trust blogs and bloggers, in many cases more that they trust other publishers. But what if we find people publishing reviews about services or products that they have a vested interest in? If I am paid by a company to review or promote their products can I be really honest in my views? And what about the breech of trust implied?

In the US the FTC (Federal Trade Commission) made a ruling in 2009 determining that bloggers have to state if they are paid for posts by an interested third party. If a blogger in the US does not state that they either receive the product to keep or are paid by someone to write the review they risk an 11000 dollar fine. In the UK the Office of Fair Trading also has extensive blogging disclosure rules. All well and good, but the report above states however that only 60% of people that find themselves in this position actually adhere to the rules, and the statistics are very likely to be skewed, as when a person is asked if they have respected the rules that almost always say yes.

How could this problem be addressed? The Technology Bloggers site refuses to publish anything that may be deemed promotion, the author guidelines are clear. But would it be possible for all blogs make this statement and enforce it, and if it were possible would they do it? The implications for trust and the spreading of reliable information are obvious.

Another issue I wish to raise involves advertising. The report offers various statistics about how many blogs have advertisement placings, before going on to analyze the reasons given either for not carrying or carrying advertising, the issue of control over who advertises and the possible financial rewards.

Here again we step into the issue of trust. If a blog has a reputation as offering reliable and quality information this reflects upon the company advertising. The placing is a two way endorsement. If advertising is not offered (as some may feel that it affects independent status or may not reflect the blogger’s ideals), how can a blog not only make money (if that is the aim) or even cover its expenses? Most bloggers sink their own money into setting up and running their blog, and if you add up the time spent in maintenance (and the administrators are undoubtedly experts in their field) each blog should be seen as a real investment in terms of many different forms of capital. You pay $120 an hour for such expertise in other fields!

Prosthetic limb technology and elective amputation

Recently on the BBC World Service I followed a news article about a young man who decided to have his hand amputated in order to have a prosthetic version fitted. His hand had been damaged in a motorbike accident and was not fully functioning, but was however still attached to his arm.

His decision rather took me aback, here was a person choosing to improve the performance of a hand with a replacement. This is fundamentally different to fitting a prosthetic hand to a person that has either lost one or was born without one. The problem seems to be in the quality of prosthetic limbs.

Prosthetic limbs can be operated through the existing muscle system, for example they can be attached to existing muscles in the arm or by using electrical impulses. In this case the muscle use generates an electrical impulse that makes the hand move.

Scientists are currently testing a system that works directly from the brain. Implants register the brain’s impulses and send them directly to the hand. You think about the movement and the hand moves.

There is another advantage too, sensors in the fingers can send signals back to the brain so the user can actually feel the object they are touching.

All of this raises some questions, soon technology will provide us with a fully functioning prosthetic hand that the user controls directly with their brain. It will be hard wearing, reliable and you can touch hot things without burning yourself, it will in fact be better that a human hand.

People might then have elective amputation in order to get one. Who can make legal and ethical decisions about such an intervention? This argument also has implications for sport. South African athlete Oscar Pistorius has recently qualified for the Olympic Games in London and will be competing with 2 prosthetic legs.

Here we are moving into a discussion about the confines of the human body, but also about enhancement. Maybe he even has an advantage over human legged athletes.

Have a look at Transcendent Man for a futurist view of how robotics and medicine in general might change humanity in the future.
