POPS Invisibility cloaks could take sting out of tsunamis "I think that this is a great idea with much potential," says Ulf Leonhardt at the University of St Andrews, UK. "One could really imagine protecting coastlines by arrays of cleverly designed concrete poles." Such structures act like metamaterials, materials whose properties result from their structure not composition, and can be used to make invisibility cloaks for light, he says. But Guenneau cautions that large structures like islands and coastlines are unlikely to become invisible anytime soon, because building the many small islands needed to protect one is such a big job. "It's crazy – maybe only people in Dubai could do this," he adds, referring to the spectacular artificial islands built there. Smaller structures such as offshore oil platforms would be easier to protect, he says.

POPSThe Methane Time Bomb As pessimistic/cynical as I am, I really didn't want us to get to this point. Perhaps it won't reach the critical point, but I'm not holding my breath.

POPS'Chemical equator' keeps southern air clean The virtual map says it all. Now it means the approach to the solution of the pollution problem needs to be tackled in different ways in each hemisphere. Atmospheric pollution is only one problem. More investigation needs to be done into the nature of oceanic pollution. it did make me wonder of the Nuclear Fusion experiments on Mururoa (Aopuni) and Bikini atolls in French Polynesia last Century. The first nuclear test was conducted on July 2, 1966, code named Aldebaran. France abandoned nuclear testing in the atmosphere in 1974 and moved testing underground in the midst of intense world pressure. A total of 147 underground nuclear tests were conducted at Mururoa and Fangataufa. This practice created much controversy as cracking of the atolls was discovered, A 1979 test conducted at half the usual depth caused a large submarine landslide on the southwest rim of the atoll. Just somehow seemed relevant

POPSA Tiny Nation in Indian Ocean An example of the majority of a nation protecting the minority from the death grip of an armed group that poses as 'Liberators' where there are no 'Slaves'.

POPSFossils tell of mass exodus from sea Creatures could develop some protection from the sun in the water, but the land was wide open, and predators were yet to get anywhere the efficiency of ocean based predators. They can understand why shelled arthropods had the protection to survive, but can't understand the survival of soft bodied things like worms and Molluscs? then perhaps they can explain why a slug like creature evolved a shell and branched unto the Snail genotype. i don't imagine life is safe anywhere for exposed slugs and worms, and solar radiation, particularly UV Light can accelerate development. and change. Perhaps they were moving to the place that was the least dangerous.
