Science&Vie

Science&Vie is a french magazine in which the recent scientific breakthroughs and theories are released(?).
I am a subscriber and after I read it, I'll post it's topics in this thread. In case you want to, I'll try my best to explain those in detail.

November 2010:
Sleeping pills that wake the conscience;
ADN travelling between species (Eg. Mice with wings, originating bats...);
Earth's Core can be renewed over time;
Ideas about storing nuclear waste.

These are the ones I read so far.

and now there is another way of stopping aids from contracting sexually.....party time!!!

oh tell me about renewing the Earth's core please, you have my full attention

This is simply a theorie, but it is the most likely one.
It explains that some iron from the outer core belonging to the west side of the planet (relatively to the greenwich meridien) migrates to the east side.
When the iron reaches the area near the inner core, it starts crystalizing due to the pressure and when it leaves the inner core, it melts again.
This theory was created to explain some problems which were:
-The sismic waves travel faster when they go the West-East way, than when they go the North-South or South-North ones. Yet, when in East-West way, they go slower than the North and South ones;
-Waves strangely speed up near the inner core(about 100km from the outer core's base) which sugests there is a more dense liquid layer than the outer core one. While migrating, the liquid in the outer core is separated from the other lighter elements, like sulfur and oxygen. The liquid crystalizes and when in the other side of the inner core, it spreads through the inner core equally and this creates the dense layer that speeds up the waves
-The inner core raises a few milimetres in thickness per year. They say that the iron that got out of the inner core is more dense than the outer core one and so, it spreads through the whole inner core.

Tell me if you got it, because this is a bit complex to explain through a computer.

imo, i think the whole earth will recycle its self over time...but this will be way after we are dead...i think the whole ice age and early history will repeat its self.

yes, plus the oxygen and the sulfur spread and all the iron comes from the outer core that comes from the inner core when joined with the light elements... it's a cycle and it takes about 100 milion years, I believe
