Hello guys :smile: Although it is offtopic, but could you please tell me which genetic engineering technology is most suitable for transferring genes from one animal species to another (transgenic animals)? I thought that it was CRISPR/Cas9, but I was told that this technology is mainly used...

Generally, why I am asking this question :oldsmile: The Euclidean geometry is based on four axioms: But all these notions such as point, line, circle, plane are the results of our eyes and our visual cortex, is t correct? None of them exist as such, but they are in our mind only! So, if our...

DaveC426913 I want to know which physiological reasons prevent this :oldsmile: jim mcnamara And it will help to boost a monkey’s (macaques for example) size from current 41-70 cm to let’s say two meters? It would be interesting to see such monkey :oldeyes: I do not imply/plan to receive an...

Hello again :oldsmile: Let’s assume that for some scientific reasons we need to have monozygotic (identical) twins in apes, for example in chimpanzee or bonobo. So I take egg-cell from female, fertilize it with spermatozoon and receive zygote and it (more precisely morula) later can be...

<mentor - Epistemology (how do we know or perceive) is not subject PF supports in the science forums - moved to General Discussion> Since my previous topic The arrangement of our visual system and the objective truth was closed I will open a new one, less philosophical. So, just imagine that...

This is a continuation of my previous topic Is there any linkage between historic Oxygen levels in Earth's atmosphere and organism size? So, let’s forget about primitive organisms and turn our attention to higher ones, for example rodents, primates :oldsmile: Are there any genes discovered...

But it seems to be quite easy and interesting (I mean results) :oldeyes: Perhaps :cool: But if I had free money I would make such experiments regardless it will yield some practical resulst in biology or not, it is just curiosity :oldsmile:

Sound easy to do, why nobody tried to do it? :oldeyes:

But if genetic alterations are not absolutely necessary, then during several years (and hence about 100 generations?) we can probably achieve desired goal? :oldeyes: So, can they in principle grow 30-40 m height? If only “niches” matter, then why nobody tried to receive such giant ferns? It...

Hello :oldsmile: I have heard that various organisms in Carboniferous period had gigantic sizes because of relatively high Oxygen level in atmosphere. Today it is equal to 21 %, but at that time it was higher: https://www.nationalgeographic.com/science/article/carboniferous So, organisms...

Hello people :oldsmile: I would like to discuss one issue here. Let’s imagine that I am looking to the sphere: I can clearly see that it sphere, not cylinder, or cube, or submarine, or dinosaur. So what I see is objective truth. But how do we generally see the objects? We have got two eyes...

BillTre Thanks :oldsmile:

BillTre Well, thanks a lot for a detailed answer :oldsmile: Insertion into genome is better if we want permanent usage of certain gene, but it requires advanced genetic engineering technologies. From the other hand, if we simply inject DNA molecule containing desired gene into nucleus then...

Ygggdrasil Thanks :oldsmile:

atyy BillTre Thanks :oldsmile: Yes, in minor sulci/fissurae if I remember correctly :oldeyes:

Frankly saying I have got very vague idea about it :rolleyes: Actually I am looking for some online–courses, could you please tell me if there are any about Biotechnology and Genetic engineering? On Coursera there are some courses, but perhaps you know better ones :oldeyes: Imagine that we...

Of course Well, let’s do not complicate the whole image and let’s assume that these factors do not change :oldsmile: but what really changes is only gyrification pattern and axons’ length. And are they explored? Interesting and very complex :oldsmile: I will tell you what is one of the...

Thanks, I wanted to know exactly this :oldsmile: And which ones? :oldeyes: Thanks, now it is clear :oldsmile:

I will read this thread a bit later, but now: In my question I meant a bit different thing :oldsmile: namely: imagine that some certain repressor is physically attached to DNA (I am dealing with neuroscience, I am not expert in molecular biology but as far as I remember many repressors are...

Hello people :oldsmile: In future I am going learn biotechnology and genetic engineering at some moderate level, but now I simply need to be aware of some basic aspects of this field :oldeyes: Imagine that we need to insert some gene(s) in ape/chimpanzee and the length of these genes are at...

Eagle9 Could you please tell me how the repressor can be removed from DNA? Is there such example (at least one) in biotechnology? :oldeyes:

Hello people :oldsmile: I guess that this is quite fantastic question/idea, but perhaps some day it will be possible to do it :oldeyes: So, in brain we have got the cortex and the axons that leave one certain area in cortex and enter another area: cortico-cortical afferents/efferents. Some...

BillTre Actually I am looking for the genes that participated not in a brain’s whole evolution (this is a big topic) but in primates’s brains’ evolution. More precisely – which genes caused humans’ (ancestor’s) brain to develop compare to chimpanzee. In other words – brain’s evolution during...

jim mcnamara Thanks :oldsmile:

Ygggdrasil BillTre Thanks guys :oldsmile:

Hello people :oldsmile: I have recently finished reading a wonderful book “Evolving Brains” by John Morgan Allman, it describes how brain evolved during the biological history. This book is really good, but unfortunately it was published more than 20 years ago, so it does not contain new...

jim mcnamara BillTre Ygggdrasil Hello people :oldsmile: I think that this thread is suitable place to ask my question and not to open a new thread: Now I read the book “Evolving Brains” by John Morgan Allman. The book is interesting in many aspects and particularly it says many things about...

Of course Thanks, I see that this (whole) situation is quite complex :oldeyes: jim mcnamara Thanks :oldsmile: I hear this first time, thanks :smile: Oh, it turns out to be much more difficult than I expected :rolleyes: Thanks, however I believe it would be very difficult to do in...

Good day guys :smile: I want to clarify one issue in molecular biology. As well-known a repressor is a DNA- or RNA-binding protein that inhibits the expression of one or more genes by binding to the operator or associated silencers. The number of genes in human genome is about 20 000, so how...

Thanks, I found that Kanto Karaoke is what I want :oldeyes:

Hi guys :oldsmile: Several years ago I installed in my computer software „Realtek High Definition Audio“. The option “Karaoke” (with red line) enabled the sound/music to be played with imaginary/seeming high or low rate (however, the actual rate remained the same), this I liked very much. But...

Thanks :smile: so as I understood Blender still is the best option

So, Blender is "better" than "OpenGL"? I study this program now :smile:

Wow, this is great, I am studying Python now :smile: And this OpenGL library is compatible with both Python and Blender? Or is it something separate tool? I will learn Python in any case, so if it is compatible for Blender I would use this option. As for OpenGL – I have not used in, never. I...

Good day! I need your advice in computer graphics :smile: I have been studying and working in Autodesk 3ds Max for years, mainly for my pleasure. Now I want/need to study some new 3D program in CG, however not for just fun but for science. Particularly I need such program that enables showing...

StatGuy2000 Thanks :oldsmile:

Guys I am looking for a textbook about Matlab where In a simple language it will be described how to use this program for solving differential equations. I am more or less aware about calculus but if I have to solve such equations in future – only with this program. So which book could you offer...

Study what exactly? :oldeyes:

Or in any western countries, but USA is still USA :oldsmile: I want to change my field of interest/study/research. Now my field is neuroanatomy and behavior, but what I want to explore it is brain’s highest cognitive functions :oldsmile: The whole point is that I do not have some specific...

Ok :oldsmile: So, my question is still open – my current PhD (sub)field can be a bit different from future PhD (sub)field, but will it make problems for applying to new PhD program? Probably it will better to ask to that university where I would apply to. :oldeyes: Thanks a lot, Canada is very...

Maybe :oldsmile: but I have got biological background, not computer and/or electricalю So, I would still prefer to receive (new) PhD in (neuro)biology since my interest is brain's highest cognitive functions and not computer’s intelligence :oldeyes: So, new master’s program, you say? I thought...

If I remember correctly – one of my friends who is now living in USA, we were talking about this issue and she told me this, hence I wanted to check if this is correct or not. Now I am dealing with neuroanatomy (actually the program where I am studying now is called “Cellular Neuroscience”, but...

Hello people :oldsmile: I am the Ph.D student in one of the eastern European countries dealing with Neuroscience, I hope I will graduate soon. But I would like to gain second Ph.D degree abroad, if possible in USA. But I have heard that American universities do not accept the persons who...

So many answers :oldsmile: Thanks Thanks, this I did not know :oldeyes:

Excuse me if this is naive question :oldsmile: Plasma is gas where all atoms are ionized. I would like to know if liquid or solid plasma can exist. Let’s take chemical element Lithium, its atom has got 3 electrons and Lithium’s crystal lattice is arranged like this...

Matterwave atyy jedishrfu Thanks a lot :oldsmile: I do not completely understand - anaconda distribution is the part of Python language? :oldeyes:

I am planning to learn Python (I am not absolutely aware about programming, but others advised me this program. They told me that it is relatively easy (much easier than C++) program, that it is widely used in science and etc.), will it be useful in Computational neuroscience (after reading the...

Please tell me which programming language is more suitable for Computational neuroscience? C++ or Python? Or maybe others?

As we know, both strands in DNA is complementary to each other, it means that nucleotide sequence in one strand completely defines the sequence in the second strand. Bacteria has got one, circular chromosome and it contains (almost) only genes. So if there are 100 genes in one strand then...

Thanks a lot :oldsmile: Yes, weird and complex :oldeyes:
