... in flavivirus entry, there is evidence that additional host cell surface molecules are necessary for flavivirus entry. Because flaviviruses are transmitted between insect and vertebrate hosts during their natural transmission cycle, it is likely that the cell receptor they utilize is a highly conserved protein (Hubalek 2001; Brinton 2002).

... and carbon dioxide from the air to make sugar and oxygen through photosynthesis for growth (Wen 2009). They grow quickly and can double in biomass size in 3.5 hours at the peak phase. Microalgae has high oil content between 20-50 % (dry weight) that can generate biofuel. Other crops may take the entire season to grow and contain lower level of ... grow in various types of waters, such as sea saltwater, alkaline and also waste water, making it advantageous to produce energy in areas with freshwater shortage. The short cell cycle and fast reproduction, simple structures, and high oil conten...

... the effects of climate change, as sea levels rise, agricultural systems are destabilized by deforestation and drought, and extreme weather events proliferate (Myers, 1993). Other ecologically-based phenomena, such as Peak Oil and geopolitical conflict over scarce resources, could further accelerate this process. The emergence of environmental migration as a social problem is not yet widely recognized by sociologists, though it evidently ... to split the labor market and drive down wages for the formal working class, or - in classic Malthusian fashion - are "written off' and left the mos...
