In Frankstein’s 1931 movie, Dr. Henry Frankstein was a victory for his victory in more than one way. While huge rays and energy flow, Frankstein’s monster on a laboratory table – his body in life by power of electricity.
A Electricity may also start life On Earth billions of years agoDespite the destruction of a scene with a little less than the classic movie scene.
The land area is about 4.5 billion years, and the oldest enforced evidence of ancient life – Stromatolite, or microorganisms preserved in layers known as microbial carpet – about 3.5 billion years. However, some scientists suspect that life has arisen sooner, arising from the accumulated organic molecules in primitive water bodies, a mixture sometimes called primitive soup.
But where did this first organic matter come from? Researchers have suggested for decades that the rays have caused chemical reactions in the ocean of the ancient Earth and the organic molecules that are automatically produced.
Now, a new research, published on March 14 in the magazine of Science Advances, indicates that almost invisible microscopic loans, created between water steam drops, could have been strong enough to cook amino acids from inorganic substances.
Amine acids – organic molecules that combine proteins – are the sons of the basic blocks of life and will be the first step towards the development of life.
Amy J. Williams, a professor participating in the Department of Geological Sciences at the University of Florida: “It is recognized that the energy catalyst was certainly necessary to facilitate some reactions on the early land that led to the origin of life.”
In order for the animation to form, they need nitrogen atoms that can be associated with carbon. The struggle for nitrogen gas atom requires breaking strong molecular contacts and consumes a large amount of energy, according to Lilims, who has not participated in the research.

Fog
To re -create a scenario that may have produced the first organic molecules on Earth, the researchers relied on the 1953 experiments, when the American Stanley Miller and Harold Auri chemicals invented a mixture of gases that shrink the atmosphere of ancient earth.
Miller, Uri Ammonia (NH3), methane (CH4), hydrogen (H2) and water ended the atmosphere in a glass field and shake with electricity, resulting in simple amino acids that contain carbon and nitrogen.
It has supported the Miller-Ory experience, as is now known, the scientific theory of generating generation: that life can appear from non-living molecules.
For the new study, scientists have reconsidered the 1953 experiments, but directed their attention to electrical activity on a smaller scale, a great authors of Richard Zeer, a professor of chemistry at Stanford University, California.
Zir and his colleagues noticed the exchange of electricity between charged water drops that are measured between a micron and a diameter of 20 microns (the width of human hair is a hundred microns.)
Zeer told ZARE to ZARE CNN. “When the drops with opposite loads are close, electrons can jump from charged drops negatively to positively charged punctuation.”
The researchers mixed ammonia, carbon dioxide, methane and nitrogen in a glass bulb, then sprayed the gas with water, using a high -speed camera to capture a weak vapor flour.
When they examined the contents of the lamp, they found organic molecules with carbon nitrogen bonds. These glycine included amino acids and orcela, the base of nucleotides in the RNA.
“We have not discovered any new chemistry, in fact, we cloned all the chemistry that Miller and Uri did in 1953,” Zeer said. He added that the team did not discover any new physics – the experiences were based on well -known principles of electricity.
Zeer said: “What we did for the first time is to see these small drops, when they are formed from water, the light is already emitting and producing this spark.” “This is new. This spark causes all kinds of chemical transformations.”
Water and life
Lightning is an exciting evidence of electricity, but also intermittent and unpredictable. Even in a billion billion billion years, Liteng may have been very rare for the production of amino acids in sufficient quantities – a fact that has issued doubts about such theories in the past.
However, the water plane was more common than lightning. The most likely scenario is that the exact photography created by fog constantly electric amino acids in the presence of ponds and ponds, where molecules can accumulate and form more complex molecules, which ultimately leads to the development of life.
Zeer said: “The micro -trucks between Microgots clearly produced all organic molecules that have already been noticed in the Miller -Woy experience,” Zeer said. “We suggest that this be a new mechanism for the pre -manuscript synthesis of the molecules that make up life blocks.”
However, even with new discoveries about careful photography, issues remain in the origins of life. While some scientists support the idea of electrically charged with the first blocks of building life, an alternative hypothesis of the initial formation suggests that the early amino acids of the Earth have been cooked around water thermal sources at the sea floor, which is produced by a mixture of sea water, hydrogen fluids -and harsh pressure.
Another hypothesis indicates that organic molecules have not arisen on the ground. Instead, they graduated in space and were loaded here by comets or asteroid fragments, a process known as Panspermia.
“We do not know the answer to this question yet,” he said. “But I think we are closer to understanding something more about what could have happened.”
Although the details of the origins of life on the Earth cannot be fully explained, “this study provides another way to form the decisive particles of the origin of life,” Williams said.
“Water is a side everywhere in our world, which leads to the title of” blue marble “to describe space. It may be the fall of water, the most important element that supports us, also plays a greater role in the origin of life on the ground than we previously realized.”
