Old life capable of revealing new tricks after all
Date:7/6/2011

ostructure sheath around their cell membrane that might serve as a sort of protection, or "cell armor," against the harsh environments in which they are typically found. Though the sheaths were discovered in the 1970s, the technology necessary for studying them in detail had yet to be developed at that time.

"M. hungatei have evolved unique features in order to survive in very harsh and low-energy environments," Gunsalus said. "The presence of cutting-edge equipment and world-class experts at UCLA allows us to closely study them, hopefully revealing their myriad of secrets."

The researchers' next goals are to elucidate the exact biological function of the granules and sheaths in M. hungatei. Many functions have been proposed for the granules, including as energy sources for cell division, or to power flagella that move the cells, or even as a protection against metal toxicity from heavy metals like iron or copper.
