I can't remeber the source otherwise I would cite it, but does anyone remember the experiment where researchers just grew foetal neurons on/in a slab of hole riddled silicon, and then promptly slid it into the spine of a paraplegic patient.
Apparently 60% return of function with physio. Considered one of the major stepping stones in biochips.
A lot of people don't realise how good this sort of thing is.This sort of tech is just a start, but if progresses, is a great boon to mankind.
The process of growing neurons in a circuit and allow interfacing of different types of neurons and electrical components is, I believe, fundamental to biochip technology.
As a student of Prosthetics/Orthotics and Biomedical Engineering, this is exactly the sort of progress needed for greater synthesis of humans and their environment.
The body is in many ways just a collection of tools, and the mind has adapted to use these tools. But when one of the tools is lost, there is great trouble in dealing with the loss(on a grief scale = to loss of a husband/wife).
Children can adapt easier as they are still learning to use their tools. This is why myoelectric prostheses work quite well with children(myo prothetics are very instinctual). This sort of technology can allow greater integration of prosthetic limbs/organs as limbs can be designed to deal directly with the human 'meatware'.
Don't even get me started on control of extenal devices like vehicles, surgical tools, or augmentation of mental systems, otherwise I'll be ranting for ever.
People would rather accept the 'reason' that makes them FEEL warm and fuzzy than take the time to think.
I think it has a lot to do with people becoming personally attached to their ideas, and beliefs. When this happens it becomes very hard for the person to objectively view a situation and apply true scientific method.
I always find it scary how people are afraid to think beyond what they are told. But then again a lot of people do choose the path of least resistance, and go with whatever they are told.
Please excuse the generalisations, but I have a lot of trouble dealing with people who will not think and do not quest for the truth.
I read your post. You stated yourself that you do not know much about eyes.
I presumed that you were talking about the person voluntarily moving their eyes over the image to view the picture.
I thought I was clarifying, in denoting the INVOLUNTARY movement of the eye in the process of the brain gaining the data at the behest of the human moving the eye. Try looking at something without moving your eyes.
I apologise if I did not understand the distinction you made of the movement of the eyes. I was attempting to clarify.
Another point of interest is the difference between male and female eyes and the degree of peripheral and central acuity.
As for the human eye and visual systems, the eyes are continually scanning and moving around as you look. This occurs as the rods and cones fire off and send information through the nerves. The rods and cones have a certain amount of time before they can fire again, so the eye moves around to continue recieving data, which the brain assembles into an image.
I don't know, BUT compaq could be onto something.
Computers that transform. I mean we have all seen trucks that transform(optimus prime), planes that transform(starscream), or even dinosaurs(grimlock).
Though I wonder if they would make that cool noise when they transform.
Just to point out that in fact cartilage does grow back, but very slowly due to its structure.
Bone, cartilage, etc are very close together in the way that they form.
In fact most of the human skeletal structure starts out as cartilage, and then resolves itself to bone in the later years(I believe 17-25 for males and females).
The cartilaginous structures in the body normally take a long time to heal due to the nutrient and blood supply being poor in collagenous areas.
Can't remember all the facts at the moment but bottom line is cartilage DOES grow back.
It is not for the patent office to have to translate the description into lay terms.
Law and government policies are written in exact language so there is no confusion over the meaning. But this does not mean that it has to be written simply. A complex issue is generally complex, and to "dumb it down" can downplay the complexity of the issue.
The work that was done cost the company money, and someone else is trying to get away with not paying for the work that was done.
Other problems that we will probably see down the road for geeks aren't just osteoporosis, but I would actually be very worried about the integrity of the IV discs, and the lack of decent activity to nourish the discs.
I know myself when I code, that hours will pass with no problem, and I force myself to get and stretch to keep the discs happy. I do this because I know the consequences and have to sit through hours of lectures on the consequences. But what about your average programmer? Are they really aware of how more physical activity they should be getting( this is of course the web designers who are always off snowboarding:) ).
In fact geek related disorders could almost be a specialist category, just to correct them now so they aren't patients later.
A lot of the gymnasts are also on diets that do not allow them to gain as much weight. It has to do with them staying the right size so that the centre of balance is maintained.
Look up the statistics of eating disorders and halting of the menstrual cycle in female athletes, particulary in russia, and china. That, of course is not to say that other countries don't do it, it's just that they are the examples that come to mind.
As far as fracture management at university and reports go, bone actually grows according to gravity and muscle pull.
Bone(hydroxyapatite), when compressed, generates a charge. This charge in turn stimulates more bone to grow.
What happens in space is that there is not as much force and so the osteoclasts(or osteoblasts, i can't remember), resorb more bone than is grown.
This is why when a bone is broken it is better to use fracture bracing(orthotics, or casts), and keep the person using the bone, so that the bone is stimulated into healing.
An example of this is the strength difference between internal/external fixation and using fracture bracing.
A brief look at any medical journal, or more specifically, prosthetics/orthotics journals.
I am hoping that this entire post was in jest, because it shows a direct non-understanding of prosthetic theory or the issues that an amputee faces with cosmesis and acceptance by 'normal' people.
BTW, that "flesh-coloured rubber washing up glove" normally costs anywhere from $50-$300 depending on the material and the amount of work put into making it lifelike.
The technology is called myoelectrics and has been around since approx 1947.
The article says partial hand, this gives a lot more control options than a transradial amputation. The pictur actually depicted using Otto-Bock batteries(you can see it just under the silicon glove used to give a 'lifelike' appearance to the hand.
The news always seems to bring out the same stories on 'bionic' limbs, and it is the same shit over and over again....
For the electronic engineers, the system is normally:
signal is taken from the muscle longitudinally
filtered
rectified
amplified
then logic circuitry is used to gain a control mechanism. this depends on available sites, muscle control, functions required.....
It is the same story over and over again....
It does take courage to break out of the cycle.
We can see this with so many forms of behaviour.
For example, the child beaten by the step father, the pedophile, the person that resorts to violence out of a lack of tools to use anything but violence, etc.
I just believe people should take responsibility and ACT, rather than REACT.
Oh well, time will tell....
I went to a private high school, and was considered one of the "nerds", "geeks", "freaks", etc.
The "jocks", as everyone seems to so unequivocally state as the big bad people, were just as lost, but they were in denial.
Of course they gave us shit, but the issue here is that the "jocks" did not seem to have an understanding of the real world.
By real world, I mean, learning how to treat people with respect and understanding, otherwise they got their arses kicked.
A couple of friends ran with local gangs due to their primary school contacts, and I myself grew up in a rough neighorhood. By rough neighborhood I mean you either learnt how to run or how to fight.
Now the "jocks" used to give us shit, but we understood that they had not experienced the types of threats that a lot of us have had to deal with, and hence when they wanted to fight, or rough or extremely aggressive, we could walk away.
And by sometimes walking away, we did it not out of fear, but out of understanding that we made a choice, not simply reacting to a threat.
High school is a time of change, and learning to deal with these changes is a part of life. If anything I am glad that I learnt more about what makes me tick, and how to cope with flux in life.
Sometimes the "jocks" made the wrong decision, and attempted to hurt myself and/or my friends. I always gave them the choice to walk away, and explained what is going to happen. Often it worked, oft times it didn't. Things got physical on a number of occasions, and each time the "jocks" lost, but also, as it was explained and the situation was complete self defence the teachers dealt more harshly.
Now as I look back and hear about the people I went to school with, some have grown and are quite likeable, whereas others have gone completely the other way and have gone to jail, or O.D.'ed, or even worse blame the rest of the world for their problems and their situation in life.
And this is what I see happening here on slashdot. A whole lot of people who complain about how crap it was to be bullied and that morons the "jocks" are, when it seems that you just have not grown out of being the victim.
Growing means making changes and adapting to a new situation. The only sad thing is if you did't learn how to get over the problems put in your way and didn't learn any lessons from the experience.
Let it go, 'cause if you have learned then, you understand that by growing past those issues, they will not be a problem in the future as you have already experienced many concurrent themes.
and BTW smile!!!

A nerve is a collection of neurons.
The tail you are thinking of is the axon of the neuron.
And I agree this is very good.
From Australia.
Does not apply, we leave university with nothing but a degree and debt.
And then we go over to America where money means something.
I am saddened by your lack of vision.
I will look forward to buying your house and family.

It has a light side, a dark side and holds the universe together.

Too bloody right!!!

That is a pretty good metaphor.

Rambus knew that they had a more than a competitive edge when the standards were being drawn up.
If a politician(moreso a minister) does not disclose that they have a vested interest in a change in the legislation, then they get investigated.
Similar to insider trading.
What does the international standards organisation do to stop this. How does a standard come about with this happening?
Surely there should be measures to stop this, or at least enforce decisions afterwards, particulary in regards to violations like this.
Or is the formation of standards similar to the UN, strictly a paper tiger?
