NASA finds alien Lifeform on EARTH!

Die Katze ist aus dem Sack, die NASA hat zwar keine Aliens auf dem Titan gefunden, dafür aber eine völlig neue Form des Lebens im Mono Lake, ein „alkalischer Salzsee in Mono County im zentral-östlichen Teil von Kalifornien.“ (Wikipedia)

Dort haben sie Bakterien gefunden, die aus Arsen bestehen. Eine komplett neue Form des Lebens die mit allem bisher bekannten Leben auf der Erde nichts zu tun hat. Was das für die Wahrscheinlichkeit von Leben auf anderen Planeten bedeutet, muss ich wohl niemanden erklären.

Von Gizmodo:

Hours before their special news conference today, the cat is out of the bag: NASA has discovered a completely new life form that doesn't share the biological building blocks of anything currently living in planet Earth. This changes everything. […]

All life on Earth is made of six components: carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur. Every being, from the smallest amoeba to the largest whale, share the same life stream. Our DNA blocks are all the same.

But not this one. This one is completely different. Discovered in the poisonous Mono Lake, California, this bacteria is made of arsenic, something that was thought to be completely impossible.

NASA Finds New Life


Nature: Arsenic-eating microbe may redefine chemistry of life: „Oddball bacterium can survive without one of biology's essential building blocks.“

New Scientist: Arsenic-eating bacteria point to new life forms: „We could be witnessing the first signs of a "shadow biosphere" – a parallel form of life on Earth with a different biochemistry to all others. Bacteria that grow without phosphorous, one of the six chemical elements thought to be essential for life, have been isolated from California's Mono Lake. Instead of phosphorous, the bacteria substitute the deadly poison arsenic.“

Discover Mag: Mono Lake bacteria build their DNA using arsenic (and no, this isn’t about aliens) „Phosphorus helps to form the backbone of DNA and it’s a crucial part of ATP, the molecule that acts as a cell’s energy currency. Arsenic sits just below phosphorus in the periodic table. The two elements have such similar properties that arsenic can usurp the place of phosphorus in many chemical reactions. But arsenic is a poor understudy – when it stands in for phosphorus, it produces similar but less stable products. This partially explains why the element is so toxic. But the bacteria of Mono Lake have clearly found a way to cope with this.“

PopSci: NASA's Newly Discovered Arsenic-Loving Bacteria Are Fascinating, but Not Aliens „This finding essentially tells us that we should ditch these assumptions and broaden our horizons. If a humble Earthling bacteria can subsist on a poisonous chemical, then who knows what might lurk elsewhere in the solar system? We’ll have to recalibrate our mass spectrometers.“
