Hitekno.com – The results of the latest searches found the results that Martian meteorites contain poison for humans. This is achieved by the detection results poison done Mars meteorite the.
Quoted from Suara.com, meteorite Mars contains this poison is given the nickname Lafayette. According to scientists, poison detection can make humans and pigs vomit.
However, the discovery of this toxic Martian meteorite could solve a 100-year mystery surrounding the pure Martian meteorite.
Lafayette was wiped off the surface of Mars millions of years ago and eventually made it to Purdue University in Indiana.
In 1931, the unusually smooth black rock was identified as a pure meteorite.
However, how Purdue University came to own the stone and who sent it to the university was unknown for 90 years.
Now, the scientists who analyzed the meteorite say the strange compounds found inside could be the clue that solved the case.
A history of potential discoveries for the Lafayette space rock, meteorite collector Harvey Nininger reported in 1935.
He said a Black Purdue student witnessed the meteorite fall into a pond while he was fishing, collected the rock and donated it to the university.
However, the evidence to support this story is scant. So, in 2019, a research team led by ine O’Brien, a planetary scientist at the University of Glasgow in Scotland, set out to solve this mystery.
“Lafayette is an absolutely beautiful meteorite sample, which has taught us a lot about Mars through previous research“O’Brien said, quoted from the Space.com page, Friday (10/28/2022).
“Part of what makes it so valuable is that it is so well preserved which means it must have been found soon after landing.“He continued.
O’Brien noted that when meteorites are left in the elements for significant periods of time, their outer layers are lost and accumulate terrestrial contaminants, reducing the value of their research.
“The unusual combination of Lafayette’s quick protection from the elements and the tiny traces of contamination it collects during the short time in the mud is what makes this job possible.“He said.
The team began their investigation by destroying small samples of the meteorite and analyzing them with a spectrometer, an instrument that looks for unique chemical “fingerprints” of elements and compounds.
O’Brien was looking for organic molecules that could indicate that life once existed on Mars, but what the scientists discovered was clearly terrestrial.
Among thousands of compounds, scientists have found deoxynivalenol (DON), a toxin found in fungi that grow on plants such as corn, wheat and barley.
When ingested, DON causes disease in humans and animals, particularly pigs.
O’Brien said DON’s detection could reach the meteorite through plant dust that made its way into the waterways, around the spot where the rock made a muddy splash in Tippecanoe County, Indiana. .
The team contacted researchers from Purdue University’s department of agronomy and botany, who determined how widespread the DON-carrying fungus was in the region prior to 1931, when the meteorite’s origins were determined.
Investigations revealed that the fungus was more common in 1919, when it caused yields to drop from 10% to 15%, with a smaller decline in 1929.
Although the fungus is more common, there is a greater chance of it being carried off the farm, carrying the DON poison with it.
Researchers are also working to determine when Lafayette may have arrived on Earth.
Two particular fireball sightings were notable, in both southern Michigan and northern Indiana: one on November 26, 1919 and another in 1927 that was home to the Tilden meteorite in Illinois, the largest space rock to hit the state in the recorded history.
With these dates in hand, Purdue University archivists began searching the institute’s records for black students attending at the time.
They identified Julius Lee Morgan and Clinton Edward Shaw, born in 1921, and Hermanze Edwin Fauntleroy, born in 1922, all enrolled at Purdue in 1919. A fourth student, Clyde Silance, studied at Purdue in 1927.
“I am proud that, a century after reaching Earth, we are finally able to reconstruct the state of its landing and are closer than ever to paying homage to the black student who discovered it.O’Brien said.
The team’s research is described in an article published Oct. 19 in the journal Astrobiology.
This is the result of research on Lafayette, Martian meteorites are toxic to humans. (Suara.com/ Dythia Novianty)
