The sparks between a few drops of water may have started life

First molecules required life The water could be created in the ground among the drops of “Mikrolightning” when the small tracements turned on the necessary chemical reactions.
“This is a new way of thinking how life blocks were formed,” says Richard Zero California at Stanford University.
It has been a permanent hole in our knowledge The origin of lifeSpecifically, how simple gases reacted to the creation of organic molecules related to carbon and nitrogen, such as proteins and enzymes, we know.
“If you look at the gases that people think at the beginning of the earth, they do not have carbon nitrogen bonds,” says you. “Metanus, water, ammonia and nitrogen are gases like.”
Experiment by Stanley Miller and Harold Urey In 1952, the electricity revealed that water and such gases can be converted into ecological molecules, but their hypothesis was that electricity came from the lightning.
However low option lightning A high concentration of the gas in the expansions of the oceans or atmosphere of the atmosphere has never been sure that he was behind the creation of earth life about 4 million years ago.
Now, Zare and his colleagues have had little drops irrigate Methane, carbon dioxide, ammonia and nitrogen gas mix, and have shown that they can cause organic molecules with carbon-nitrogen links without external electricity sources.
Because water spray drops generate small electric charges, Zare says. “The smaller drops are negatively charged, the greater charges positively,” he noted. The Lenard effect has fallen to something called, water drops, a waterfall, colliding and breaking, creating an electric charge.
What the team discovered using a high-speed camera, when enough drops of the opposite loads are close enough, small electricity Jump between the two, Zare calls Mikrolightning.
It is a way to create static electricity, or is built and unloading in the clouds of lightning. “When the water drops are included in each other’s nanometers, you get an electric field and this electric field causes breakdown,” he noted.
Mikrolightning brightness had enough energy – to lose gas molecules to lose an electron, creating organic molecules with carbon nitrogen, including hydrogen cyanide, anxious acid and uracil, one of the components Wna.
“It’s amazing that Mikrolightning can start chemistry starting with nitrogen. However, the reported observations are credible,” says Veronica Vaida At Colorado University. “The origin of life involves a new and renovated role for water.”
The work involves waves or small sparks in waterfalls that would be enough to give the necessary chemicals to start life on this planet, says Zare.
Water sprays are ubiquitous and often land in the rocks, which would allow organic chemicals to accumulate in their crises. Then the field will dry and be re-wet. Wet wet cycles combine shorter molecules, or polymerize, are longer.
“Research suggests that mikrolightning would be plentiful in the surrounding rich water environment, and maybe having been driven in prebiotic chemistry, especially other energy sources, such as lightning or UV radiation,” says Vv download Indian Pune, Indian national chemical laboratories.
Vaida believes that work also has consequences for searching for extraterrestrial life, which is often driven by looking for the presence of others planet or moon. You may need to search for places that allow small drops of water to collide, he says.
