Map of life on Earth could be used on Mars

...lowstone caldera, hydrothermal deep-sea vents, and boiling silica-depositing springs. "Is it a coincidence, then, that we have three hydrothermal habitats and three major groups of prokaryotes? We aren't sure, " she said. "This could suggest that we have some really ancient habitat specialization. These lin...

NC State researchers redesign life for Mars and beyond

...es reach more than 100 degrees Celsius, or that of boiling water. Occasionally, the organism is spewed out into near freezing deep-sea water. The NC State research, funded for two years and $400,000 by the NASA Institute forAdvanced Concepts, entails extracting a gene - called superoxide reductase - from P....

War on terror meets war on cancer

... the air from each tube, then putting the tubes in boiling water. The water from each cell cake was boiled into steam, which was routed to another tube where the water condensed. Before undergoing this process, half of the bacterial cakes were washed with water with four different ratios of oxygen-18 to oxy...

Patterns in genome organization may partially explain how microbial cells work

...tive microorganisms, including one that thrives in boiling hot springs, also exhibit patterns in their genomes that are highly nonrandom. "This high degree of organization of prokaryotic genomes is a complete surprise, and this finding carried many implications that biologists might not have considered befo...

Bacteria beat the heat

... thrive in surroundings ranging from Antarctica to boiling hot springs? A team of scientists from the Weizmann Institute's Plant Sciences Department, led by Prof. Avigdor Scherz, has found that a switch in just two amino acids (the building blocks of protein) can make a difference between functioning best at...

DOE JGI finishes 100th microbial genome

...vironmental challenges can go to the extremes--the boiling hot pools in Yellowstone National Park, for instance--and lead to new biotechnology products. "DOE JGI has played an invaluable and otherwise unavailable role in the development of new enzymes for industrial use," said David Mead, President & CE...

From hot springs to rice farms, scientists reveal new insights into the secret lives of archaea
