SUMMARY: A team of Colorado University researchers has uncovered bacteria that primarily use hydrogen as their fuel source in the colourful hot springs of Yellowstone National Park. Bacteria, such as salmonella, have been uncovered which use hydrogen for fuel before, but nobody expected this was happening in the intense heat of the hot springs. By using very sensitive detectors, they discovered that there's a constant supply of hydrogen being delivered to the bacteria from hydrothermal vents. Hydrogen is the most common element in the Universe, and finding bacteria that consumes it in extreme conditions further expands the places life could potentially gain a foothold.
