Previously unknown bacteria discovered on the space station could help grow plants

  Previously unknown bacteria discovered on the space station could help grow plants Three previously unknown strains of bacteria were found growing in the International Space Station, according to a recent genetic analysis. The discovery could help scientists develop better ways to grow food on Mars. The analysis, published in the journal  Frontiers in Microbiology , describes how astronauts collected four strains of bacteria within the space station in 2011, 2015 and 2016. It was part of an ongoing surveillance program that tasks astronauts with monitoring eight sites of the space station for bacterial growth. Astronauts have already sent hundreds of samples back to Earth for analysis, and thousands more are scheduled to be sent back on return missions. The newly discovered strains belong to a family of bacteria called  Methylobacteriaceae , which is commonly found in soil and freshwater. These bacteria help plants grow, fix nitrogen and stop pathogens. Credits-Nasa Int...

  The search for Alien life Our professor, Mr. Premarathne has written an Article mixed in all terms of Astronomy, English and The limited knowledge of us humans. You definitely want to read his fantastic idea and his talented essay. The search for alien life  Well, we all know it is still unknown about an extra-terrestrial life form or simply aliens. Even finding a tiny microbe out of our world will be a turning point of humans. But we are not searching for microbes, we are searching for life forms that are truly mind boggling. Some people believe that aliens are continuously visiting our home planet. We can’t say that statement is false because nobody knows if there are aliens that have more advance technology than us and visiting other planets in the universe. Our view of aliens is more likely mythical. Those humanoid creatures that are abducting people and use them to experiments sounds entirely bound up but we should not blame because again “nobody knows”. In my view I se...
