  1. You posted it as if the whole ice shelf has fallen off into the sea and with your bias against people who denounce climate change, I thought I would tell people what has actually happened. Whereas I agree that climate change is happening and to an large extent it is probably humans fault, that is no reason to spin the facts, as if the facts are there they will speak for themselves.
  2. Well according to this News organisation who I would trust far more than CNN it is about the size of the isle of man which is far smaller than half of Scotland, and according to that it was only 40 square miles. Plus the fact it has yet to break off it has just cracked, some expect it to stay in place as the Antarctic summer is ending and to see what happens in the spring.
  3. Yes it is, it is completely, however probable this maybe the case impossible if the outcome is prevalent in any form as is the case here doesn't exist. Even if being darker were a set of recessive alleles which it clearly isn't there would still be a probability of it occurring. What is this article talking about anyway it seems to be quoting from 1500 and 1800, genetics as a useful science has only been round 100-120 years, I mean I am reading quotes, which I might add will be highly inaccurate, from 300BC The article doesn't even understand how genetics works if 2 alleles are codominant. I will give an example: For the sake of argument we have an individual with the genotype Aa who has the phenotype of brown. So they have one 1 Black alleles (A) and one white alleles (a), now coincidently the male who the woman mates with also has the genotype Aa so you get a cross of: Aa with Aa Now the theoretical outcomes say that the chance of get Aa is a half, (as if you cross them you can get Aa or aA which are the same thing) where as the probability of getting aa or AA is a quarter therefore the child can either be lighter, darker or the same colour as the parents, (AA being black, Aa being brown and aa being white) with a higher probability of being the same colour. Of course that is over simplifying it, but if they are completely codominant as this article seems to presume, incorrectly I might add, then the child can quite easily be darker. This article seems to presume quite hilariously that the Chromosomal alleles "blend" together within each other to make new polynucleotide sequences that magically create working proteins, where as this may happen it doesn't happen with in exons, chiasmatal formation happens in the intron sequences, which are just nonsense code.
  4. This is just a ridiculous statement in general, you don't even have to look at it genetically. If a white woman and a black man have children, the child are not white are they, (well technically they could be) they are a mixture of the two skin tone and therefore the child must be darker than the woman.
  5. My personal opinion on the matter is that it should only be given to people who are terminally ill or with a chronic condition and that the person must be of sound mind and judgement to make the decision independent of others influences and it shouldn't be made by anyone other than the individual it concerns. To further that point all known medical treatments should have been tested and have failed or have had little effect as well as with the patients permission experimental treatments which are being researched tried as well. There should also be some kind of paramount on a time frame that has to have passed before the action can take place so that someone can't just wake up and have an epiphany that they want this kind of procedure done. They must make that decision and then dwell on it for a period such as 6 months, or maybe a less time frame depending on the condition, this would reduce the number of people who would have regretted it (if they could) in the future. This would also mean that people who do want to go ahead with it would have a point to aim at and get their affairs in order by.
  6. What? How is it GTP if it has 4 phosphate groups? You have to radiolabel the alpha phosphate on the nucleotide as this is the one that will be added to the RNA strand with the creation of a pyrophosphate. You need to understand the mechanism of however a polynucleotide chain is created before you will understand this.
  7. It sends an electric shock through the body that is supposed to work as an artificial action potential to stop the heart from fluttering, however if the voltage gated channel proteins aren't working no action potentials can be sent period, unless you introduce an inhibitor of the drug previous to the attempt.
  8. Can't you make a smoothie for the fruit part.
  9. There are various theories that they could come in from space, such as panspermia, or from volcano eruptions. To get the height of the clouds isn't very hard at all Saharan sand can travel thousands of miles in the air and that is full of bacteria.
  10. I got a B at GCSE maths, which as most will know isn't great adn I am doing a degree in biochemistry, the maths is easily doable with a bit of help from your course mates to explain it to you. Most of what I have done is thermodynamics and genetics, which is a lot of probabilities as well as other things. If you are planning to do that you must have done chemistry and if you can do the maths in that you will be fine.
  11. To add to that, the ice currently reflects more of the light due to its colour (white) where as if it melts the sea which is darker will absorb more of the heat and therefore expand quicker.
  12. Indeed that is what I was thinking, they won't turn white and Australians won't turn black, selection pressures are different now to "basic" ones such as those. If you are white you can put on some sun screen if you are black you can take a vitamin D tablet.
  13. Indeed and even if it was in reality how would you know it was in computer program if the sequence that cause the advantageous mutation didn't exist in real life. I can't really see how you can turn off advantageous mutations unless you know them or which clearly we don't.

    That is plasma building up in the legs causing swelling due to a lack of movement, that isn't actually pooling of blood, well I suppose in a way it is as plasma is one of the main constituents of blood, not sure what it is called though. The other one is caused from excess pressure being exerted on areas for a long period of time, in laymens terms they are bed sores causes by a lack of movement as normally even when you sleep you are adjusting your body and rolling over however if you are in a coma or something similar you can't do these default actions. I believe they are 2 different conditions however I would guess they have similar causes.
  15. That isn't entirely true it is well known that infants specialise their brains during the first few months and years. For instance before 18 months experiments have been to show that when a baby looks at a TV screen with a monkey on it and then the same tv with a different monkey that looks very similar they will be interested as it is different, however after this age their brains have specialised to recognise differences between humans so when the 2 different monkey's are show the infant becomes uninterested for the second one as they think they have already seen it. The brain removes unnecessary functions, so in this case maybe it would remove that function or just greatly reduce perception for that colour.
  16. I think what they meant is would the brain be able to comprehend the information or would it have removed the area they would translate that colour for efficiencies sake as the colour was never present. It is an interesting question, I don't know the answer but I presume there would be no effect as what colour would you remove considering most colours are a mix of others.

    It does go down to the bottom as if you kill someone and then leave them there blood pools in certain areas of the body which they are lying on and have pressure on, that is how most investigators know a body has been moved after they have been killed as the murderer doesn't place them in the same position and the blood has now congealed meaning it won't move any more so isn't in relation to the ground. I'm not sure how it does it I would guess it just flows down through the circulatory system and maybe slightly my osmosis out of cells, i'm guessing that all of it doesn't move down to the bottom just a higher percentage than normal does.
  18. Yes but if you have a higher concentration then K1 will be faster anyway as will K2 and most like K-1 as well, everything changes.
  19. My equipments works pretty good, but then again that is biochemistry stuff. Awesome lab report though.
  20. Yes, but it isn't looking towards the future, they are just looking for some quick fix.
  21. It doesn't solve anything though, instead of adding something that was not there, you are taking something that was there and adding it again, it is a futile cycle. It doesn't add anything, but it doesn't take anything away either, with most ideas you do the same activity without adding CO2 so it is negative CO2 emissions compare to using a fraction of oil, where as this is just on par, or even still positive as you still have to grow the crops and make the biofuel which won't be 100% efficient.
  22. Yes but it is still taking farm land away from food production plus the fact that it isn't really solving anything, if everything turned to biofuel it wouldn't lower CO2 emissions they would just balance out, what you need is a fuel that can easily be transported and produced that doesn't produce CO2, otherwise we aren't really getting anywhere, cause biofuels at best are a short term fix which companies are wasting R&D money on when it could be better spent on more "radical" projects.
  23. Indeed, most people don't die of AIDS anyway, it is normally a secondary infection and when you don't have a sufficient health care system or an immune system how long do you think you are going to survive in africa, cause it won't be long enough for anyone to realise that the reason you died from some normally harmless virus/bacteria.
  24. I was going on the fact that lots of people in some countries call there teachers professor even though they aren't. Not many people are professors lots are doctors but few in relative terms professors.
  25. Your professor who I guess isn't actually a professor, is wrong km isn't a measurement of the affinity of an enzyme for its substrate, that is only true when K-1 is much greater than K2. Km is the substrate concentration that gives half Vmax.
