Nano-tech and medicine / But all this new stuff, out of what ?
« Last post by PART-4-ES-Paula on 19 July , 2018, 19:21:15 pm »
Hi there, it´s me again.
Ready to get your mind to explote with more datums about nanoscience?
Nanotecnology is a realm very innovative, that promises a lot of advances in diferents areas, in our case we will talk about the sanitary aplications, that looks like the revolution and the future of this field, but someone knows where did this technology come from?
"The sick, the elderly and the wounded suffer a disorganization of the atoms caused by a virus, the passage of time or a car accident" (. . . ) "In the future there will be devices capable of rearranging the atoms and putting them in their place".   Engines of Creation .Eric Drexler .1986 (1)
With these words, Eric Drexler advocated the revolution that has suposed the application of the knowledge and the technologies of the nanocosmos and gives rise to the term nanomedicine. Drexler made great contributions to "molecular nanotechnology"  and is considered to one of the big visionaries of this issue, but the origin of the new scientific and
assistance era that we are going to live comes from the father of"nanoscience", Richard Feyman (Nobel Prize in Physics), who in 1959 proposed to manufacture products based on a reorder of atoms and molecules with his famous conference titled "There´s Plenty of Room at the Bottom") (2).
He marked a milestone for the development in this field, signify the possibility of moving things atom by atom.
The discovery in the 1980s of the tunnel microscope and the discovery of fullerenes (a type of carbon that had very interesting properties despite its size) led many scientists to take nanotechnology into account.
This is an overview of the beginnings of nanotechnolgy, but there is plenty of information if you look into thsi two sorces, the first one explains An approach to the development of general capabilities for molecular manipulation by Eric Drexler  , and the second one is the transcript of the classic talk of  Richard Feynman. They are the most important preacher of this new science.
Now we know the start, what it is (thanks to the post of my mate Rachel, Nano…What?), but do we know to who or where is this incredible term reaching? That a point for the next post. Let me know if you will like it. I can´t wait to read your answers! Thanks for Reading me.
Best wishes.

Hi everyone,

When I started researching for my nanotechnology project, I first looked about how developed was the nanotechnology field; the actual nanoproducts, the main businesses... If you started investigating about nanotechnology, and more  concretely about nanomedicine, I’m sure you would have discovered its numerous applications which can solve some of the problems our actual society faces. Although most of the population usually relates nanotechnology with science fiction, we can actually obtain “nanoproducts” from the market; in fact there is a wide range of nanodrugs’ offer nowadays. (If you are interested on nanopharmaceuticals which are actually on the market, you can download the PDF file you can find below).

In spite of their incredible advantages, some businesses have already tagged nanotechnology as negative including a “non-nano” symbol in their products. Nanodrugs, as our example of nanoproducts, have been proved to be safe in a short period of time, being innocuous for human beings or less harmful than the original drug; the drugs which are actually comercialized have been tested and proved as harmless by prestigious regulatory agencies such as the Food Drug Administration or the European Medicines Agency. Therefore, why would some businesses avoid these innovations? The answer is simple: some experts had said that we actually ignore the repercussions of these systems in a longer period of time, were the products can be harmful for patients. What do you think about this controversy? Should we use these drugs without assuring the safety of the patient or continue with the testing of these products in order to obtain a higher regulation? The debate is assured.

I would like to hear about your opinions as soon as possible!

Nano-tech and medicine / What's up with the Nanoscale?
« Last post by PART-4-ES-Raquel on 19 July , 2018, 11:38:11 am »
Hello everyone,

As you might already know, the Nanoscale binds together the fields of Technology and Science, being the common variable in both disciplines. But what is there really that is so promising about this scale, which is nothing but another unit of lenght?
The perks of the Nanoscale lay in the so-called size-effects that materials experience when being reduced to the billionth part of the metre (that is 1nm=10-9m). The change of structure the materials undergo when they are modified by chemical and physical methodologies provide us a wider scope to work with. The behaviour of these nano-objects or nanofauna is a discipline entirely of its own: Quantum Mechanics. Quantum Mechanics understand the tiny and the changes that occur in the Nanoscale that are so important to the development of Nanotech, a few of which are (1)their tiny volume and thus their wider scope for interaction (they can break through biological barriers), (2)more room for storage in computing processing units. Nevertheless, in our projects this is not a topic we will be tackling. However, for those of you who want to know a little more about the innerworkings of this discipline and see a few detailed examples of materials in the Nanoscale, I'll leave a link below:

http://www.pnas.org/content/pnas/104/17/6885.full.pdf (self-assembly of supramolecular structures, the thermal properties of nanoscale molecular systems (DNA melting and nanoscale water meniscus formation, etc.)

https://www.nationalgeographic.org/activity/properties-matter-macro-nano-scale/

Please share any other interesting reasons why you think the Nanoscale is so integral a part of Nanotech. I only listed two examples of the perks of nano-objetcs and their properties. Do not hesitate to share more.

Thanks for reading,

Hi!
I found this article about a new hand prothesis which I think is really interesting. It provides users the sense of touch. I found it amazing because they needed to combine modern technology with the brain. 
As McLoughlin says “The power in this is that we don't have to trick the brain; we use what was already there so the brain doesn't have to learn how to interpret signals from the prosthesis."

Cybernetic prostheses / Re: Cyborgs: are they still human?
« Last post by PART-5-ES-Alejandro on 18 July , 2018, 18:18:30 pm »
I als think this topic is very interesting, and as María said, we discussed this with our expert and between us in the national congress. I think I shouldn't give my personal opinion in order to let you create your own idea about this, and once you have created it, then yes, we will discuss about it. So to help you building your own arguments I let you here the biography of Neil Harbisson, who is considered to be the first cyborg existing. We also talked about him in the national congress and as I said before, this is a very interesting topic to talk. I will also leave you a TED talk he did.

Nano-tech and medicine / Re: INTRODUCTIONS
« Last post by PART-4-ES-Paula on 18 July , 2018, 15:58:54 pm »
Hello everyone, welcome to the IYSC Forum,
I am, with the two more Spanish participants,that have already introducted themselves, one of the finalist in the second phase of the INVESTIGA I+D+i program, from the line of Nano-technology focused on Health.
I am quite delighted and grateful of being able to participate in a forum like this one, in where I will be glad if we could reach to discuss interesting themes about our line, and manage to end in common conclusions. I hope my contribution will be useful for the development of your knowledge on this area and the exchange of information rewarding for everybody.
In the project, that we have been working on in Spain, consists in three main parts.
The introduction shows what nanotechnology is, name the big one´s in this subject and talk about some of the most important devices that take part in this new aim, among other things.
On the knot we have being concentrated on the improvement that this field could provide to the NCDs (Non-Communicable Diseases), giving prominence to cancer. Moreover, we have been treating the theme of nanotechnology on the regeneration issues, like for example: tissue engineering.
Finally, on the conclusion we wanted to add some ethics, analyzing the possible negatives consequences of this technology.
Us per those topics are concerned, I have available great sources of information,
however, I am a researcher, and I will always love looking for new aspects inside this line.
I look forward to hearing back from all of you.
Best wishes,

Cybernetic prostheses / Cyborgs: are they still human?
« Last post by PART-5-ES-Maria on 18 July , 2018, 15:08:43 pm »
Hi!
Something we talked about in the national congress in Spain was what being human means. Prothesis can provide people new or better capacities. If they have this abilities we all can’t, can we still considere them human?
I found this article (https://www.quora.com/Is-a-cyborg-still-considered-human) which I think is very interesting. It talks about this topic and I considere it can be very useful. Please, share your opinion.

Cybernetic prostheses / Are artificial limbs better than the real ones?
« Last post by PART-5-ES-Maria on 18 July , 2018, 14:52:51 pm »
Hello!
Technology can provide people better qualities than biology. Prothesis can replace organs making humans stronger, faster... What do you think about this? Ethically, this is a problem cybernetic prothesis cause.
Here I leave you an article about how, in some cases, technology overcome biology. Write about your opinion please! I think it is a very interesting topic we could debate about.

Space trash / What is orbital debris?
« Last post by PART-3-ES-Elsa on 18 July , 2018, 14:37:45 pm »
Good morning

The first question we have with this research project is about the definition.
I have found several pages about this topic:
https://www.nasa.gov/audience/forstudents/5-8/features/nasa-knows/what-is-orbital-debris-58.html
https://en.wikipedia.org/wiki/Space_debris

I will research lots of information about the definition and then I will investigate about the Kessler syndrome
https://en.wikipedia.org/wiki/Kessler_syndrome

I would like add a section about the participation of Spain in this problem.

I hope I can help you.
