Life comes from a “cosmic BBQ”?

Scientists from the US Department of Energy’s Lawrence Berkeley National Laboratory and the University of Hawaii at Manoa using experiments to reproduce a decline of stars containing carbon-rich environment (hot spots), trying to figure out some of the specific molecules are formed.

“Reproduction environment such a hot spot for the first time, no one has ever seen before”, Musahid Ph.D. from Berkeley Lab chemical experiment Ministry Ahmed said, “The results show that DNA is likely to be born in such a hot spot region, we joked to ‘universe barbecue’. ”

Life may be born in the universe barbecue. Scientists claim that one of the basic building block of life may come from hot stars.

They found that the universe of stars near the hot spot (hot spot) is a great place to generate ring nitrogen molecule, it is this nitrogen molecule ring spawned DNA. Once confirmed, the study will have a major impact on life on Earth originated academic study.

Scientists from the US Department of Energy’s Lawrence Berkeley National Laboratory and the University of Hawaii at Manoa using experiments to reproduce a decline of stars containing carbon-rich environment (hot spots), trying to figure out some of the specific molecules are formed.

For decades, the astronauts telescopes have been looking for signs of possible formation of DNA molecules in space, especially quinolone (quinolone), Dr. Ahmed explained. They focus on the area between the stars, also known as the interstellar medium, but few care about the environment in which these carbon rings, in theory, known as the “Golden Mile” (Prime Locations).

Therefore, in order to reproduce such a star near the “Golden Mile”, Ahmed and his colleagues at Berkeley laboratory use advanced light source (ALS) and hot nozzle, scientists have confirmed the use of the latter produced during combustion of soot .

Ahmed experiments in thermal nozzle used to simulate the pressure and temperature of carbon-rich stars nearby. The researchers injected a mixture of gaseous nitrogen, carbon and hydrogen at 700 Kelvin (450 ℃ or 800 ℉) hot nozzle, and then found the gas nozzle transformed into a quinolone and isoquinoline containing substances.

This temperature is close to the ideal temperature of the hot stars in the vicinity, for the formation of DNA provides the best place. “Conversion reaction to cross an energy barrier in the natural space, this barrier across the nearby stars, experiment can be done.” “This means that from now on, we can find these biomolecules in a star of the” , Ahmed said.

DNA, also known as DNA, is the genetic material in humans and almost all other organisms.

 

According to the researchers say, quinolone and isoquinoline produced in a hot environment, and then as stellar wind and the interstellar medium is released. “Once released into space, cold molecular clouds, these molecules condense on the cold interstellar particles and then further processed and functional,” said Dr. Ralf Kaiser added. “These processes may be able to produce more complex molecules with biological, such as DNA and RNA to form a vital base.”
