Viroids are plant pathogens that consist of a short stretch (a few hundred nucleobases) of highly complementary‚ circular‚ single-stranded RNA without the protein coat that is typical for viruses.[1] The smallest discovered is a 220 nucleobase scRNA (small cytoplasmic RNA) associated with the rice yellow mottle sobemovirus (RYMV).[2] In comparison‚ the genome of the smallest known viruses capable of causing an infection by themselves are around 2kilobases in size. The human pathogen hepatitis D is

Thermal power plants are one of the main sources of electricity in both industrialized and developing countries. These plants have drawn flak on consumption of non-renewable sources of energy at a rapid rate and also since they release huge amounts of greenhouse gases into the atmosphere. The anti-greenhouse gas activists are calling for thermal power to be replaced by other cleaner sources of energy.
