Rains Bring a Microbial Massacre to Chilean Desert

Automatic TRANSCRIPT

This is science Americans sixty seconds science. I'm Christopher Dodd Yatta Yatta, come and desert in Chile is one of the driest spots on earth. Sometimes can't even see any life at all. I say it was a key. Those guys were really boring because nothing to see Armindo us boost was born and raised in the comma, he's now in Astro biologist at the Spanish national research council's center for Astro biology, and he says with closer inspection. Life can be found there microscope. Another to see metro recently in those giants places in either Tacoma, then in two thousand fifteen and again in twenty seventeen freak storms from the Pacific flooded. The comma ten times, the usual amount of rain fell turning some of the driest parts of the desert into lagoons, but the desert's hardy microbial life didn't exactly burst into bloom looking at it microscope. I couldn't see anything. So what does Jesus pricing? I was expecting to assume two things moving all around. Round. But it could see anything in fact after sampling three of the newly submerged areas his team found only a quarter of the microscopic species they'd previously isolated in the desert region. Perhaps he says because the water killed the rest through a process called as Modig shock. So it doesn't have the mechanisms to get all the water that is going to sell to to get it out. So they start inflicting small anti burst out. Their results are in the journal scientific reports the microbial massacres should serve as a cautionary tale. He says as we search for similar dry adopted lifeforms on Mars because several of the life detecting experiments performed by the Viking Landers involved. You guessed it, adding water, and it would be tragic if we killed the first extraterrestrial life we found. Thanks for listening for scientific American sixty seconds science. I'm Christopher Don. Yata?
