NASA-Funded Research Discovers Life Built With Toxic Chemical
NASA-funded astrobiology research has changed the fundamental knowledge about what comprises all known life on Earth.
Researchers conducting tests in the harsh environment of Mono Lake in California have discovered the first known microorganism on Earth able to thrive and reproduce using the toxic chemical arsenic. The microorganism substitutes arsenic for phosphorus in its cell components.
"The definition of life has just expanded," said Ed Weiler, NASA's associate administrator for the Science Mission Directorate at the agency's Headquarters in Washington. "As we pursue our efforts to seek signs of life in the solar system, we have to think more broadly, more diversely and consider life as we do not know it."
ScienceDaily (June 7, 2010) — Two new papers based on data from NASA's Cassini spacecraft scrutinize the complex chemical activity on the surface of Saturn's moon Titan. While non-biological chemistry offers one possible explanation, some scientists believe these chemical signatures bolster the argument for a primitive, exotic form of life or precursor to life on Titan's surface. According to one theory put forth by astrobiologists, the signatures fulfill two important conditions necessary for a hypothesized "methane-based life."

The governments haven't been interested in finding life, they've been more bothered about manipulating their people. That's why researchers and scientists interested in searching don't get funded properly and usually discredited at the same time. You can bet on it that if it was in their interests there'd be life all over the place and we'd be hearing about it every day.

Governments are especially not interested in identifying life where big companies are exploiting it for profit. I have always suspected that mineral nodules on the ocean floor may be a form of life, but we'd have to study them for a thousand years to watch one "day" in their slowly evolving lives. Those nodules are consider to be a mineral resource worth trillions of dollars. Imagine the uproar if the EPA put mineral nodules on their endangered species list.
