"Many of the molecules found by ROSINA DFMS in the coma of comet 67P are compatible with the idea that comets delivered key molecules for prebiotic chemistry throughout the solar system and in particular to the early Earth increasing drastically the concentration of life-related chemicals by impact on a closed water body. The fact that glycine was most probably formed on dust grains in the presolar stage also makes these molecules somehow universal, which means that what happened in the solar system could probably happen elsewhere in the Universe."

ITER's Tokamak

The most advanced approach to fusion involves
using magnetic fields to confine the deuterium
–tritium plasma. This is the route to be taken by
International Thermonuclear Experimental
Reactor (ITER), which will build a fusion reactor
at Cadarache in the south of France [ITER is an
international coallition among China, the European
Union (EU), Japan, Russia, South Korea and the
US]. The project will cost $10 billion to build and
run. ITER will use magnetic fields generated by
superconducting coils to confine a plasma of
deuterium and tritium in a donut-shaped chamber
called a Tokamak. The plasma will be heated to a temperature of 100
million degrees so that the deuterium and tritium nuclei can overcome
their mutual repulsion and undergo nuclear fusion.

I read this for a while, and I suppose my physics has yet to be so good that I could understand the concepts behind. It would be helpful if charts or figures could be used. I am more visual.
