    Help Needed on Science Friendly Software

    Superb - I have to check this out. Thank you. Hope it is royalty free.

    Help Needed on Science Friendly Software

    Thank you Bufofrog. I will try it out. How is Corel Draw?
  3. Hi all out there, I am writing a short summary article on biological molecules etc... for my school and perhaps for the wider community. I want to make my article exciting by incorporating scientific images. I want to make it more exciting and include images of amino acids etc... but showing each individual atom. Is there animation/image software available for science education purposes? Alternatively, is there low cost software that can help me to bring my article to life? for example, something like this: Thanks, in advance
  4. This is more appropriate for a religion forum. If you have a scientific version of this question, please make the enquiry. However, IMHO most people on this forum do not agree that humans have souls. (I do but I am in the minority). Also, IMO, most people on this forum believe that chemical reactions in neurons cause our feeling of "self". Some of the replies were hilarious, you have to admit it....
  5. Does this mean that a time may arrive when we can stop using GPS and avoid silly incidents like that below?
  6. Thank you for the reply. I will look up each of the developments. This is fascinating material. I am sure you are an inspiring lecturer with your sheer breadth of knowledge. Please do not leave this Forum. Have a good day. Jimmy

    More Conclusive Evidence that DM does exist:

    As far as I recall, the evidence for subatomic particles and most molecular biological phenomena is indirect. However, at least the electromagnetic spectrum interacts with all matter and we can "see" a pellet of DNA at the bottom of an Eppendorf. How on Earth do you have conclusive proof where the whole of the electromagnetic spectrum does not allow access to it. I could hypothesise that God has ordered the angels to push apart galaxies and expand space and I can use the same evidence that you have used. Where there are galaxies with apparent less dark matter, there are just fewer angels.

    More Conclusive Evidence that DM does exist:

    I'lll be honest and say that I don't know much about this subject. However, what would be conclusive is the actual measurement and characterisation of dark matter otherwise we might as speculate that leprechauns or unicorns cause the expansion of space/galaxies from each other. So, IMHO, dark matter is a hypothesis that fits in with the current data but we cannot say more about it yet but speculate. Even the authors are being cautious. https://iopscience.iop.org/article/10.3847/2041-8213/ab0d92/meta
  9. Hi Charon Y, I do try to keep with literature for my Yr 12 and 13 (A level) classes. I also try to incorporate information from papers in these lessons if it is not available in textbooks. I was not aware that live interactions between organelles have been "seen" for such a long tie. I did use fluorescent imaging and observed shedding of fluorescent proteins using a confocal light microscope many moons ago. However, I could not discern the smaller organelles (Golgi apparatus, RER etc...). I realise that parts of narratives that are incomplete are not helpful to students. However, these can be made available to bright students who are keen for extra extension to the dogma that we teach them and who can accommodate uncertainties. I agree with the misuse of titles to make each scientific discovery into a sensation. Thank you for your reply. I will look up the latest microscopy techniques if you could point me in the correct direction.
  10. This is news to me. I have been teaching the textbook version for 21 years. It is about time that the textbooks are now changed. It amazes me that the new science is not incorporated into textbooks sooner. Great find and I will re-read this information. Electron microscopy has been such a useful tool to provide a snapshot of what goes on in cells but the fact that light microscopes have been developed which can provide intercellular interactions "live" is a most welcome innovation to cell biology.

    Bacteria power

    Interesting find. I did not believe it at first but then read these quotes: https://www.quantamagazine.org/swarming-bacteria-create-an-impossible-superfluid-20180726/ There is also a model stated here: https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.121.018001 As for having a motor driven by bacteria, that need warmth and a continuous flow of suitable nutrients - dream on!
  12. I am so glad that China, an economically developed nation, have entered the space race in such an able manner. Let's hope that they open up data and pictures to the world in an open and unselfish way. This is a great moment for the whole of humanity - not only China and let's not be small minded here. Congratulations China!
  13. /nice one mate. Thank you for the information.
  14. First of all, it is no surprise that computer scientists would consider DNA as an excellent information store. Treated correctly, DNA can be frozen and kept for potentially hundreds of years if I believe the magazine article which I scanned very quickly today. Also, there are 2 billion base pairs in the entire chromosomal content of one cell nucleus which are responsible for the encoding of roughly 21,000 genes to make a human being IIRC. However, here is the bit where I need help. The article claimed that 9 base oligonucleotides could be used to code for short instructions and that 13 of these 9 base oligonucleotides could encode 13 trillion "words" of code (in the same way that sentences could be broken into words). I am assuming that I read this correctly. Not knowing coding, can someone clarify: a) What it means by words of code and b) What technique would allow this code to be read quickly enough for practical purposes? In the meantime, I will hunt for the original article...
  15. Is there a particular model which is more plausible than others about the movement of DNA from the organelle to the nuclear chromosomes? I am making an assumption here that the genes for mitochondrial replication are spread amongst several chromosomes as a "buffer" to avoid deleterious mutations, but I could be corrected...
