Good and simple information can be found on page 1102 in 6th edition of Halliday's 'fundamentals of physics'. Oklo, located in the Republic of Gabon, was discovered about 30 years after the first artificial nuclear reactor was built by Fermi et al.
US will soon be atacking Iraq once again for cheap petroleum. Why do you think your country has any interest on local grown sugar cane if they want world control of petroleum?
Actually, the reason for the huge sugar cane production is that you make good destilled drink out of it. Very good, cheap... people call it 'cachaça' - 40%GL.
Now there is also a point on slavery in this production: people work under a very hard sun and if they get caught eating sugar cane (which is delicious, a lot of sugar, much water) they immeaditely lose their job. They're hired and work on daily basis and have no sindicate. It is slavery indeed.

Mule Gives Birth

"A horse has 64 chromosomes and a donkey has 62, so a mule is left with 63, an uneven number which cannot divide into chromosome pairs. This should make a mule unable to reproduce."
That is very correct. Now I wonder if scientists test every insect if they aren't able to reproduce with other insects of different species (and generate fertile children).
My point is, there are millions of different species of insects, but often they just differ by some dots in some part of the body, but are already described as a different specie. What about the definition for different species used above and in the above thread?
Well, if you live of indirect evidences of everything, science is pretty much just about a guess... if a hypothesis is not applicable, then some things you predict out of it might not be true.
This is something: by inhibiting NF-kappaB action, fever has very interesting properties like inhibiting virus proliferation and activating Heat Shock Proteins. Fever is a defence mechanism. It is itself a relieve for pain. There's nothing wrong with the body if your fever vanishes and you get a terrible headache - it's perfectly natural.
My last viral infection I treated with 12h fever straight, and there was no sign of it left. Now keeping a fever gives farmaceutical industry absolutely no money, which is why likely this is not much revealed, but you can read about it studying physiology...
I forgot its name, but there is a range of distance to a planet in which rocks are reduced to dust. Well, this is a theory: rocks (satellites) release dust by some act of gravity, in some range of distance. There are some smaller moons around Saturn which seem to follow this rule. I don't believe that our moon or one of the other two are within that range.
...with only a 3" mirror telescope in my backyard and only doing minor observations like globular clusters and some planets and stars I'm no longer considered an amateur astronomer.
In june 2000 this was already published in Nature."Adhesive force of a single gecko foot-hair" by Autumn, Liang, Hsieh, Zesch, Chan, Kenny, Fearing and Full.
The complete reference for those who access a library or nature.com: Nature 405, 681 - 685 (08 Jun 2000) or simply the first reference if you search for gecko.
So this article could have been published LONG ago.
For those who do not write programs, != is the logical operator not. So 'wheight!=mass' is a correct statement which says 'wheight not equal mass'.
Now answering to the thought, I try to build ideas to make antigravity something real.
The gravitational force is given by F=GmM/r^2. Then take one of those masses to be negative and the formula says that it would show gravitational repulsion.
Nothing hasn't been yet shown, but it was pointed out by a french scientist that in one of his experiments, antimatter showed some gravitational repulsion, but this was not the key idea of his study so he did not carry on further investigations regarding this subject. And he denied my explanation with negative mass...
Hey, take antigravity stuff, it would have negative wheight (wheight!=mass). Now think of antimatter, possibly with negative mass, also could have antigravity properties. That would rock! Except that you wouldn't be quite able to walk in a antimatter ship or whatever.

José Lutzenberger (who recently passed away) wrote many good texts on modern agriculture and GM food. In this homepage you can download them. Most of the texts are in portuguese, some in german and some in english.
So right, LaTex is already enough when you want to write math-stuff. Well, I don't know how to use, compile and whatever, but I believe it's close to that staroffice formula program.
I wouldn't think of genetic engineering. Bacterias evolve faster than we can make experiments... they're millions and billions in a small place. They're a mutation factory, that's why they evolve. Short life-time, huge population, natural selection for adaptation to some enviroment.
Now nanotech would be something. We could make some nano-probes which would identify bacterias (in some biochemical way, membrane receptors, for example) and destroy them somehow (a violent method, nano-laser or some other cool killing machine). That would rock!!!
When the first antibiotics (penicillin) were made, it took a lot of time for bacteria to evolve and become imune. If they now have suceeded in becoming imune soon after its discovery, normal antibiotics (chemicals) are likely not to be effective much longer. The whole way of thinking antibiotics... bacterias always adapt after some time.
We need to think of a new way to fight bacterias or we're all going to die!! cool...
And I don't feel a little sorry for the great farmaceutical industries
Plastic is a major problem. There's almost no recycling in Brazil which is one of the most developed of the developing countries (and is where I live). There are huge amounts of garbage around major and even small cities.
That is one of the reasons why I do not like capitalism: something has to sell so it has to be presentable. To be so, it's likely to have some layers of plastic protecting it and so on.
Also, most things which go inside a refrigerator have plastic. Necessary or not, it goes all into the garbage. Milk, for example, goes into boxes which wheight quite something.
Now biodegraadble plastics are developed almost everywhere. In Brazil, some of them have been produced with local available material (like parts of mandioc which is abundant as sun...). But why bother with the use of new technology if petroleum is abundant... that's a problem of capitalism and lack of political will.
There's something in the movie... 'Build me an army worthy of Mordor' This can't be. The Palantír just allows you to gaze far away, it doesn't transport any sound. What Sauron is able to do (according to The Book) is to look upon the one who gazes at him. Pippin, for instance, looked at him and later told Gandalf that 'He just looked at me and I understood'. This happened after Isengard was laid down... oh, perhaps i shouldn't have said this.
I just did some calculations powered by windows calculator. First I calculated the energy those T-Rays have. This is given by:
E = planck*[speed of light]*frequency
Planck's constant is 6.63e-34 J/s (check Halliday), speed of light is 3e+8 m/s and the frequency is something like 1e12 1/s which is THz frequency. Then you calculate the equivalent mass for this energy which is given by E=mc^2 (yes, this formula has some use) or simply make
h*c*f = m*c*c which is h*f/c = m
Now pick this mass and divide it my the mass of a resting eletron (=9.11e-31 kg, according to Halliday). By now you should have something around 2,4. Means, one photon of this kind has an equivalent mass of 2,4 resting electrons or one accelerated to some velocity, god know how much.
I mean, after all, I'm not allowing anyone to scan my body with this T-Rays. It's way more dangerous than X-rays (with which I work) and Gamma-Rays (which are emitted by the sun and hardly reach us). No thanks.

I wonder why countries like USA worry about CO2 emission and do not sign the related treaty, i.e. Kyoto protocol...
More orbital garbage, more walking blinking things to watch at sunrise/set... I'm kind of blind, so it's pretty hard to find sattelites.
