(PhysOrg.com) -- In 1996, when scientists examined a meteorite from Mars previously uncovered in Antarctica, they were intrigued by what looked like microscopic fossils of ancient Martian life forms. Now, using new technology ...
A team of researchers at Virginia Tech working with one colleague from Dongbei University of Finance and Economics and another from Santa Clara University has developed a process for recycling polystyrene that involves the ...
(Phys.org)—Hydrogen has the potential to provide an alternative, clean energy source, particularly as applied to fuel cell technology. Current fuel sources involve carbon-containing fossil fuels or carbon-containing organic ...
The first direct evidence that humans played a substantial role in the extinction of the huge, wondrous beasts inhabiting Australia some 50,000 years ago—in this case a 500-pound bird—has been discovered by a University ...

Decomposition (or rotting) is the process by which organic material is broken down into simpler forms of matter. The process is essential for recycling the finite matter that occupies physical space in the biome. Bodies of living organisms begin to decompose shortly after death. Although no two organisms decompose in the same way, they all undergo the same sequential stages of decomposition. The science which studies decomposition is generally referred to as taphonomy from the Greek word taphos, meaning tomb.
One can differentiate abiotic and biotic decomposition or biodegradation. The former one means "degradation of a substance by chemical or physical processes, eg hydrolysis). The latter one means "the metabolic breakdown of materials into simpler components by living organisms", typically by microorganisms.
