Hybrid grass may prove to be valuable fuel source

...predicted that if just 10 percent of Illinois land mass was devoted to Miscanthus, it could provide 50 percent of Illinois electricity needs. Using Miscanthus for energy would not necessarily reduce energy costs in the short term, Heaton said, but there would be significant savings in carbon dioxide produ...

Secrets of the deep may hold key to life on other planets

...buffers them from almost all major events, such as mass extinctions or climate change. "Their evolutionary history is likely to be radically different to other, photosynthesis-based communities ?they may even mirror life forms on other planets." Very little is known about the geological history of the...
