Researcher Claims Find Beings on Mars
CALIFORNIA - Scientists have been studying how microbes can survive in low temperature conditions . Scientists are also studying how microbes respond to stress and damage conditions .
Reported by TGDaily , Monday ( 10/14/2013 ) , a new NASA - funded research Allows Scientists to study microbes in the ice . Researchers at the Department of Biological Sciences LSU figure out how microorganisms can survive in permafrost or permafrost .
In fact , with this research could lead to the possibility that microbes hiding in the ice on Mars . Brent Christner , professor of biological sciences and his team recently revealed on DNA repair in microbes trapped in the ice .
The research was published in the journal Applied and Environmental Microbiology . Researchers focused on the analysis of DNA , the molecule that encodes genetic descent instructions used in the development and function of all organisms .
" Microbes composed of macromolecules that if frozen , exposed to decay. We know of many spontaneous reactions that lead to DNA damage , " said the researcher .
The worst kind of damage known as ' double - stranded break ' , where microbial DNA is cleaved into two separate parts . To create a chromosome function , then two separate parts that must be put back together .
Christner said , this kind of damage can be avoided if the cells remained frozen in permafrost for years Welcome to Thunderbird . " Imagine if the microbes in the ice for a long time and this DNA progressively dismembered . Later will come a point where microbial DNA Becomes so damaged and no longer a viable information storage molecules . What 's left is a corpse , " Explains the researcher .
Therefore , the microbes inside the ice in a long time Considered to be terrible and could Eliminate valuable information for Researchers . However , the Researchers were Able to revive claims that microbes buried in the ice .
Microbes are buried in the ice until the age of Hundreds of Thousands to millions of years . In the experiments conducted Christner , he reveals could revive some kind of bacteria that is in the bottom of the ice Guliya in Qinghan - Tibet plateau , China West . Ice is 750 thousand years old .
This research is expected to reveal Whether on Mars actually has the potential Emergence of life through microbial findings .
