Here's a businness idea: Like where you have a milkman to deliver milk, you have a gas man to drive round a mini tanker and fill up your car with diesel or petrol so you don't have to waste time doing it. Don't know whether it would be legal though. And your customers would have to get copies of car keys for you. Would probably appeal to rich people in rich estates where one gas man could make sure every car was full of petrol in the morning. Assuming it was not in a garage. OK its a bit of a barking idea, but I thought it was cool

It would be interesting to see whether humans could evolve into Cockroaches Or would that be devolve?

Well if I had some first class levers in me I'd be able to open a bottle of beer and crack some nuts without having to use a tool...

15 years ago when I was a physics student I wondered whether for a coil with a dc current flowing through it the energy contained within the resultant magnetic field is equal to the kinetic energy of the electrons flowing around that coil. Since then Ive worked in sales and computing, and have forgotton all my favourite theories that would have allowed me to calculate it. Does anyone know the answer?

Its the grim reaper. I think death has occurred when you just stop thinking at all.

I don't think death is a scientific term at all - it is a cultural concept of the end of life. In the most conventional sense yes death means when all the brain cells are dead, but I don't see any reason why they can't be chemically repaired and brought back to life. Indeed I read about a case of a dog that was dead that was brought back to life, and indeed what about babies that have been starved of oxygen for hours when buried in earthquakes and under ice that have survived. Their brains must have been considered dead surely?

Ooo that's HHEEAAVVYY man

I have always felt that sex is an enjoyment no different to eating chocolate or having a beer. However it is also the case that I haven't married and had kids. Society doesn't want everyone to be like me, because the human race would die out. So it applies an artificial moral bias stating that "casual" sex is shallow, by which it means less valid than sex in a relationship that will eventually lead to babies. Due to our tribal nature as people - looking up to our elders (pop stars, church leaders, the queen etc) we buy in to this propaganda so keeping the population going. In the past several thousand there was no need for anything artificial because we lived in small tribal units with no anonymity or birth control, and the tribal elders directly controlled all sexual access to the women. Themselves, usually, and it was a free-for-all (when they weren't pregnant). So in summary I suggest you go get it if you can young man!

Do a search on Ebay. For magent For example Check out http://stores.ebay.co.uk/South-Pole-Magnets They have a very attractive collection. But some of them are quite repulsive... Hope you break your fingers hehe

in answer to the original question, since most people with HIV/Aids are gay men (in this country) then this group will have had more time to develop immunity to HIV. So they'll be the survivors. But as they are gay they won't be willing to reproduce. So the species will die off anyway.

I looked up Rimonabant on Wikipedia: http://en.wikipedia.org/wiki/Rimonabant And it seems to be an appetite suppressor. Will be interesting to see how it does. I also looked up "fatty acid metabolism" on wikipedia http://en.wikipedia.org/wiki/Fatty_acid_metabolism and the article says "The breakdown of fat stored in fat cells is known as lipolysis" and "The following hormones induce lipolysis: epinephrine, norepinephrine, glucagon and adrenocorticotropic hormone" Then I clicked on "epinephrine" and it turns out that this is a stress hormone. So on the face of it it would seem you have to be stressed to lose weight. It would explain why people who are worried are often thin, and why fat people are jolly. So the question is, and I know that this is such a simplification, is can you get "epinephrine" into your bloodstream over night without waking you up or causing nightmares?

How about making a rucksack that could be filled with helium after it has been packed. Then it would be lighter to wear.

Why not?

So perhaps if you were to artificially "use energy for real" with my idea of taking blood through dialysis and removing the energy from it would work? BTW When I wrote this post, I didn't get any replies to it, so I thought the title "drugs for weight loss" was not a good title. So I reposted it under the bichemistry section: http://www.scienceforums.net/forums/showthread.php?t=20057 and there are around 5 posts there also. Have a read if you like.

Well of course the word "dialysis" is taken to mean the treatment given to people who have kidneys that have failed. They work by taking blood out of the arm, cleaning it of waste products such as urea, and putting it back into the arm. Just like what the kidneys do. In my case, the machine would take the blood out of the arm, and do something to it to "trick" the fat around one's belly to think that you've just had a strenuous session at the gym, and cause the fat to burn. The key question is what specifically causes fat to burn. Is it just low blood sugar levels, or is it this in combination with other chemicals or hormones. So if you put someone on dialysis every night for a few hours, you could get it to drop your blood sugar levels very low, so cause fat to burn, and then remove the waste products of this burning, be it sugar or ATP or whatever, and then increase blood sugar levels by the morning before you wake up, so you don't feed drained.

Time travel is possible forwards. All you have to do is to go to bed for a few days, and there you are. Time travel backwards is not possible. Why? Because if you travel backwards you see the world as it was. But you already know (because you have memory) how it is going to be, from then to the point when you travelled back from. Since this has already happened, because you lived the first time through the time when it happened and witnessed it for youself, your entire actions will be consistent so as to repeat exactly what happened before. If you have any power to choose anything different then your surroundings will act against you to prevent this, and you know this to be the case as you witnessed this the first time round. So time travel into the past is strictly on a read-only basis. But then we already know this as we have many abilities to read stuff from the past. Like this message for example.

That can't be right. Can it? Surely the idea is that even from the perspective of those travelling you can't get to your destination in less time than the distance to the destination divided by c?

When you exercise, you lose weight. Which is why fat people are often encouraged to go running to lose the flab. But what is the biochemical process that occurs here? My guess, and please correct me if I'm wrong, is that when you exercise your muscles turn Adenosine triphosphate (ATP) into Adensosine diphosphate (ADP) in turn releasing energy to propel you along. To complete this "krebs cycle", as I believe it is called, the body metabolises sugar in the bloodstream to convert ADP back into ATP so that the proportions of these two chemicals don't become too uneven. Then when there is a lack of sugar, the body starts using fat to create ATP, thus burning it. So the question is what chemical has to be present in either increasing quantities or reduced quantities as a result of sugar levels running low in order to cause fat cells to start to be metabolised. And also what are the waste products of this process? where am I going with this question? Why not offer a solution to fat people such that instead of having to go to the gym to keep fit, they hook themselves up to a blood machine every night (aka to a dialysis machine) to do three things with the blood: 1. Add to it the chemical/hormone that causes fat to burn. 2. Convert any excess levels of ATP (caused by the burning of the fat) to ADP, so as to keep the levels of these chemicals even thoughout the night. 3. Remove any waste products of the fat burning process so as not to overwhelm the kidneys. There may be a requirement to add extra oxygen as well. Any thoughts?

Sorry I forgot what I was going to say

I mean it is ONGOING presence or absence of these chemicals in the blood that would be the key thing. Yes you could give them the blood of a thin person but this would only temporarily fix the problem until whatever factors causing the weight gain reassert themselves in terms of what is in their blood.
