Worlds Oldest Living Thing!

Scientists say a patch of ancient seagrass in the Mediterranean is up to 200,000 years and could be the oldest known living thing on Earth. Australian researchers, who genetically sampled the seagrass covering  40 sites from Spain to Cyprus, say it is one of the world's most resilient organisms - but it has now begun to decline due to global warming.

Australian scientists sequenced the DNA of samples of the giant seagrass, Posidonia oceanic, from 40 underwater meadows in an area spanning more than 2,000 miles, from Spain to Cyprus.

Methane Hydrates Resource







Methane Hydrate - 
The Gas Resource of the Future









Methane hydrate is a cage-like lattice of ice inside of which are trapped molecules of methane,  the chief constituent of natural gas. If methane hydrate is either warmed or depressurized, it will revert back to water and natural gas. When brought to the earth's surface, one cubic meter of gas hydrate releases 164 cubic meters of natural gas. Hydrate deposits may be several hundred meters thick and generally occur in two types of settings: under Arctic permafrost, and beneath the ocean floor. Methane that forms hydrate can be both biogenic, created by biological activity in sediments, and thermogenic, created by geological processes deeper within the earth.
