When Steward introduced the spacecraft to asteroid, scientists wait patiently their opportunity to look into the pieces of distance Rock is on the lab, hoping to answer some of the personality questions.
In Danny Glavin, a sample higher sample, wanted to solve a lasting secret in his work: Why all the things known to live left hand-hand things for Amino acidsMolecules make protein?
His time arrived for about ten years later. Glavin and a team of investigators examine grit from SentutThe rich is rich asteroid made of freely stoned stonesBut what they have got casts the curveball. Instead of supporting one of the leading books – that the first sunlight likes different kinds of left and brought such ancient ingredients – no indicate that it is completely attractive.
“I have to admit, I was disappointed or disappointed,” said Glavin. “I felt like this 20 years of research on our lab and my work.”

Many acids are aminos, whether they are used in biology or not, coming in two mirror forms. Each molecule has a central atom of carbon and other atoms attached, tend to be in one place or back. This property, called the Chirality, is like the left and right hand: they are the same, but when them put them, and the thumbs will be the opposite.
In the world of life, left “left,” and sugar, in part, that constructed the DNA spine, remained right, providing double helix signed on the right. Homogeneity found between both funnings of scientists because left and left and left types of all these molecules are equally available in uniform chemical mix.
In fact, it speaks, if all biological molecules take the restore, which can work well. So if life would take another way, why didn’t he do it? The “hand” uniform “is a secret ingredient in the clinic, and more, he did have Left turn? Has left-handed amino acids begin in cosmos, or later in this planet?
“The basic question for all of us should be a way,” said Iris Chen, a professor of chemical engineering and biomolicular engineering in UCLA, who had not participated in the Assoid Study. “Does the atmosphere be determined by our type of life, or our biology resulting risks and opportunity?”

Scientists inform each time using what is collected by icler-Rex-Rex Mission, short of Origin, visible translation, identification resources, and Revolith-Revolith ExplorerAnalyst “hand” of individual amino acids. Bennu’s mineral pieces can be older than a 4,6 year old. These Stardent’s characters are likely to appear Death of the stars or supernovas that eventually led to the construction of sun and planets.

In order to make their own study, they place the form of “Bennu Tea,” boiling a small amount of rocks and dust in the water and acids to execute organic computers. Then they use the main strategies to identify organic molecules, including 14 acid amino acids that use protein, carry out the genetic regulations. Some of the Recent findings They have been published this week’s weekend Natural environment.
“I have to admit, I was disappointed in a minute or disappointed.
For several decades ago, researchers found that meteorites – Rocks walking space and Crash-arrived In the world – they have a higher appointment of left amino acids than the rights, 60% over the top. Perhaps the Space Stones sent computers to accept chemicals next to the land Deep Vents at sea building the first cells. Another evolution is perhaps.
Those results, accompanied by the knowledge that space rocks are exploding ecosplines, leading scientists to believe ancient Assyoids, solar system caplule, which will also produce left-handed. If the solar system is actually dating the time, perhaps the obvious light in space was the cause. Little liking in nature can be turned into a great division over time.
Scientists think that the metorites and the planet collision may be that the origin of the Life chemistry may even earth land, including left amino acids.

But researchers have found left and right that includes equally. Now Glavin Wonders If the past courses are not allowed, perhaps they are contaminated by the global protein when they fall down. Jason Dwurkin, Project Science for Osiris-Rex MissionYou think there may have been a different reason Bennu Buck Trend.
“Bennu is an example of one genuine meteorite type to survive the Earth’s arrival, so it’s not really our collections,” said Dorkun.
Perhaps the fact is that the formation of life is determined by the flip of money. Once a successful pattern is established, the template continued evolution. Proteins and Enzymes, young drivers within cells, come together as a gigsaw puzzle. If life comes from left amino acids, switching to the left amino acids later may have stopped everything to work. There are major benefits: if people are based on right amino acids, they cannot eat and digest plants or animal products based on left amino acids.
The investigators have made Versions of Environmental Protein with amino acids with a lab. They work alike, but it is very difficult to spend. Enzymes are usually slow down the bottomless floor. As your hairstyles on a world of countries, a tool will not work when the plug and opt out.

Some scientists consider the meaning of the problem express concern about future development in mirror cells. If people are infected with harmful midror germs, their immune system can be prevented, can tie the fight against fighting. A group of organisms recently wrote poster in accidents, as reported by New York Times.
Despite Glavin’s disappointment that Bennu did not produce chirality beas, research continues. He and his participants plan to study the many asterroid samples to investigate other amino acids.
And there may be silver inserts: Some astronomers propose to use different molecules as Biosignature. The combination of both types of external sample can elevate chemical molecules without organisms. But the excess of one type can be an unknown life index.
“In fact, it can actually make life easier in some ways because we do not have this powerful risk,” Glavin said. “We made it) we believed that if there was one or other raising, there could be biology behind.”
