The centerpiece of U.S. espionage is the CIA, created by the National Security Act of 1947 (50 U.S.C.A. Â§ 402 et seq.) to conduct covert activity. The CIA protects national security interests by spying on foreign governments. The CIA also attempts to recruit foreign agents to work on behalf of U.S. interests.
Most known extremophiles are microbes. The domain Archaea contains renowned examples, but extremophiles are present in numerous and diverse genetic lineages of bacteria and archaeans. Furthermore, it is erroneous to use the term extremophile to encompass all archaeans, as some are mesophilic.ew sub-types of-philes are identified frequently and the sub-category list for extremophiles is always growing. For example, microbial life lives in the liquid asphalt lake, Pitch Lake. Research indicates that extremophiles inhabit the asphalt lake in populations ranging between 10 6 to 10 7 cells/gram.
The organisms also developed a defense mechanism that protected them from cold temperatures. The halophiles and methanogens are part of a hardy group of microbes called extremophiles, which thrive in the harshest environments on Earth. Maryland Astrobiology Consortium/NASA/STScI. These close-up images, taken by an electron microscope, reveal tiny one-cell organisms called halophiles and methanogens.
