ìWhen the plasma confined by a magnetic field reaches the high energy point of self-organisation, a zonal flow is generated. These zonal flows produce regions in the plasma known as transport barriers, which stop the loss of particles and energy out of the plasma system,î Dr Shats said.

In the natural world, there are already examples of these powerful flows. The turbulent water flow around the Antarctic continent prevents the freezing waters from escaping north, preserving the ice cap on one side and the tropical water on the other. ìThis is very similar to the transport barrier that we find in plasma,î Dr Shats said.

U.S. Activity Update on Tsunami Reconstruction

In the two years since the tsunami, much work has been done to rebuild lives and livelihoods and U.S. government assistance has totaled more than $840 million in this effort. In addition, U.S. charitable donations have exceeded $1.8 billion, according to the Center on Philanthropy at Indiana University.

Tsunami money 'still not being spent'

Figures compiled by the UN also show that a number of governments which pledged to send aid money have only given a small amount of what they promised or in some cases, nothing at all. The tsunami, which left thousands of children across south-east Asiaorphaned and saw millions lose there homes, was one of the most destructive in history. But despite a massive aid effort, about a tenth of the £3.3 billion offered is yet to be delivered while only £1.7 billion has been spent.
