SUMMARY:"Science Talk over the counter" led by faculty PI Oded Beja - "Bact
 eria\, metagenomics and solar energy harvesting" [No Categories]
DESCRIPTION:Location: The Nola Sox Bar\, 4 Shalom Aleichem Street\, Ziv Cen
 ter Haifa  Prof. at the Faculty of Biology Oded Beja\n Affiliation: \n Hos
 t:\n Abstract:\n\n 	What are "Light Sensing" proteins and how were they di
 scovered in the waters of the Sea of Galilee\, for the first time since 19
 71?\n 	What is "harvesting solar energy"\, what is the connection to photo
 synthesis\, and how are these indirectly related to the visual system of v
 arious animals and also humans?\n 	What are rhodopsins? What are bacteria 
 and how is the color "deep purple" related to them?\n\nThe main way throug
 h which energy enters the food webs on Earth is with the help of protein s
 ystems that absorb energy from sunlight. Beja laboratory investigates the 
 various systems with which microorganisms "harvest" energy from sunlight t
 o satisfy their energy requirements.\n\nIn the lecture\, I will talk about
  new families of light-sensing proteins (rhodopsins) that were discovered 
 in the waters of the Sea of Galilee. Proteins that are responsible for har
 vesting solar energy (using solar energy to create chemical energy). Proce
 sses carried out by various microbes. I will describe the role of proteins
  in absorbing light of different colors and turning it into energy availab
 le to cells.\n\nIn the lecture\, I will also talk about the field of "meta
 genomics". A method that allows us to look at the genomes of bacteria and 
 viruses without the need to grow them.\nUsually\, when you want to study t
 he genomes of bacteria and small creatures - you are required to grow them
  in what is called a "pure culture” in the laboratory. And since 98% of 
 those marine microbes cannot be grown in the laboratory\, you have to find
  other ways to look at their genomes and make predictions about what they 
 do for a living in the sea.\n\nlocation: The Nola Sox Bar\, 4 Shalom Aleic
 hem St.\, Ziv Center Haifa.\n\nEntry is free\, you must reserve places in 
 advance here in the form: https://forms.gle/mHTLV7aoPyxmv8CT8\n\nThe lect
 ure would be given in Hebrew.\n\n&nbsp\;\n\n&nbsp\;
