Prussian Blue Salt Linked to Origin of Life

This is Prussian blue. This salt could cause substances essential for life.

ScienceDaily (Dec. 15, 2009) — A team of researchers from the Astrobiology Centre (INTA-CSIC) has shown that hydrogen cyanide, urea and other substances considered essential to the formation of the most basic biological molecules can be obtained from the salt Prussian blue. In order to carry out this study, published in the journal Chemistry & Biodiversity, the scientists recreated the chemical conditions of the early Earth.

We have shown that when Prussian blue is dissolved in ammoniac solutions it produces hydrogen cyanide, a substance that could have played a fundamental role in the creation of the first bio-organic molecules, as well as other precursors to the origin of life, such as urea, dimethylhydantoin and lactic acid," Marta Ruiz Bermejo, lead author of the study and a researcher at the Astrobiology Centre (CSIC-INTA), said.

Urea is considered to be an important reagent in synthesising pyrimidines (the derivatives of which form part of the nucleic acids DNA and RNA), and it has been suggested that hydantoins could be the precursors of peptides and amino acids (the components of proteins), while lactic acid is also of biological interest because, along with malic acid, it can play a role in electron donor-recipient systems.

The researcher and her team have proved that these and other compounds originate from the cyanide liberated by the salt Prussian blue (the name of which refers to the dye used in the uniforms of the Prussian Army) when it is subjected for several days to conditions of pH12 and relatively high temperatures (70-150ºC) in a damp, oxygen-free ammoniac environment, similar to early conditions on Earth. The results of the study have been published recently in the journal Chemistry & Biodiversity.

"In addition, when Prussian blue decomposes in this ammoniac, anoxic environment, this complex salt, called iron (III) hexacyanoferrate (II), also turns out to be an excellent precursor of hematite, the most stable and commonly found form of iron (III) oxide on the surface of the Earth," explains Ruiz Bermejo.

Hematite is related to the so-called Banded Iron Formations (BIF), the biological or geological origin of which is the source of intense debate among scientists. The oldest of these formations, more than two billion years old, have been found in Australia.

The researchers have confirmed in other studies that Prussian blue can be obtained in prebiotic conditions (from iron ions in methane atmosphere conditions with electrical discharges). The synthesis of this salt and its subsequent transformation into hematite offers an alternative model to explain the formation of the banded iron in abiotic conditions in the absence of oxygen.

Ruiz Bermejo concludes that Prussian blue "could act as a carbon concentrator in the prebiotic hydrosphere, and that its wet decomposition in anoxic conditions could liberate hydrogen cyanide and cyanogen, with the subsequent formation of organic molecules and iron oxides."

THE PIG FART HEARD AROUND THE WORLD


“Assenture” dumps Tiger



The only real issue here is, DO CORPORATE SPONSORS have the right to pass judgment on professional athletes PERSONAL LIVES. Any consumer that allows that to happen is selling their soul to stupidity. Our athletes bless those leaches by allowing them to use their name.



This BS should be the beginning of a sportsman revolt against any company that is ARROGANT AND IGNORANT ENOUGH TO THINK THEY CAN PASS MORAL JUDGMENT ON ANY BODIES LIVES.



Time to send a message folks.



Big business thinks that they own this country. They think they own our athletes. They think they own our government. They even think they own us. Enough is enough. The corporate pig that just dumped our SUPER STAR has been consulting our jobs OUT OF THIS COUNTRY for decades. They are not anybodies friend.

They are blood sucking vampires. IMHO



Tiger in a sense has given the people of this nation of sheep a GOLDEN OPPORTUNITY to rip off that lamb’s skin and show corporate America the wolf/tiger hide within. Tiger has given pro golfers the same golden opportunity to reclaim some dignity in their lives. You guys have been kissing corporate butts for far too long.



Let the greedy SOBs know that they are guest in your game, not rulers. Don't play until Tiger plays if you have too.



I say screw any CORPORATE sponsor that acts in such a fashion.



Boycott their products. Leave them on the shelves. If their sales reps come calling leave him/her sitting in the lobby until their butts are stuck to the chairs.



This country is dying because it has lost the guts to fight. Time to go looking for those guts boys and girls. No better time than right now.

Morals are a product of our environment. We got them from our parents, our friends, our teachers, and our society. We were not born with those opinions we learned them.



America’s moral values have sunk to an all time low. Do we even know what they are anymore? We kill thousands of our fellow man all over the world every day simply because they grew up in a different moral molding environment than we did and we don’t even shed a tear. Our government representatives sanction this AMORAL behavior every day and we do not even blink an eye.



IT IS LONG PAST TIME FOR US TO PUT A STOP TO THIS NON-SENSE. TODAY MY BROTHER AND SISTERS RISE-UP, RISE-UP and SHOW THE WORLD THAT THE AMERICAN PEOPLE ARE TAKING CONTROL BACK FROM THOSE LOW LIFE SCUM SUCKING PIGS. THEY WILL ALL BREATH A HUGH SIGH OF RELIEF, I AM SURE.



If we can't stand up for our Super Stars, then who or what? If you are a SUPER STAR it is time to stand up and be counted. Show the pigs who is really the Super Star. Don’t play if you have to. Screw the money; it is the principle that counts.



WE GOT LAZY AND WE LET THE LOW LIFE SCUM SUCKING PIGS RULE THE HOUSE FOR A WHILE. THEY STOLE US BLIND. THEY HAVE STOLEN OUR MONEY, OUR POWER, OUR RIGHTS AND THEY SHOW NO SIGN OF STOPPING OR EVEN SLOWING DOWN. BUT THE TIME TO NEUTER THE PIGS HAS COME. IF WE DON'T DO IT NOW, LORD HELP US. WE HAVE LEARNED TO SLEEP WITH THE PIGS AND LIKE THE SMELL.



TIGERS FAMILY AND THEIR PROBLEMS ARE THEIR BUSINESS AND JUST THAT. CAN THE SELF RIGHTEOUS RHETORIC EITHER PRO OR CON AND GET OUT AND KICK SOME CORPORATE PIGS BUTT.



Copy this fast boy and girls, the pigs will start squealing real quick and it will soon be gone. Send it to everybody you know. Post it again if you choose. Make it pretty, make it spread. Post it on every news story on every blog on every place you can think of.
