Hot Springs In Japan Give Insight Into Ancient Microbial Life On Earth
Earth was not always the blue-green world we know today: the early Earth’s oxygen levels were about a million times lower than we now experience. There were no forests and […]
Studying Thermophiles In Yellowstone National Park
Ask any Yellowstone park ranger about hazards in the park, and you will soon learn that hydrothermal features (not bears) have caused more harm than any other natural threat. Park […]
The Biology, Microclimate, and Geology of a Distinctive Ecosystem Within the Sandstone of Hyper-Arid Timna Valley, Israel
Microbial endolithic communities in the sandstone rocks of the southern Negev Desert, particularly in Timna Park, were initially discovered by Imre Friedmann and Roseli Ocampo-Friedmann in their pioneering study about […]
Partnership Between Algae And Bacteria Reveals Secrets Of Evolution
The microscopic alliance between algae and bacteria offers rare, step-by-step snapshots of how bacteria lose genes and adapt to increasing host dependence. This is shown by a new study led […]
Orbital Biosignature Survey: Brilliant Phytoplankton Bloom In The Baltic Sea
Editor’s note: with the future advent of powerful telescopes that may be able to resolve habitable worlds in images composed of a few pixels, large biological phenomena such as algal […]
Microbial Diversity Of Coastal Microbial Mats Formations In Karstic Habitats From The Yucatan Peninsula, Mexico
In this study, we report for the first time an exploration of the physicochemical characteristics and the prokaryotic diversity of three different types of microbial mats from karstic habitats located […]
Chemoautotrophy In Subzero Environments And The Potential For Cold-adapted Rubisco
The act of fixing inorganic carbon into the biosphere is largely facilitated by one enzyme, Rubisco. Beyond well-studied plants and cyanobacteria, many bacteria use Rubisco for chemolithoautotrophy in extreme environments […]
Tracing The Evolutionary History Of Bacterial Circadian Clocks On Ancient Earth
To better understand the circadian clock in modern-day cyanobacteria, a Japanese research team has studied ancient timekeeping systems. They examined the oscillation of the clock proteins KaiA, KaiB, and KaiC […]
Light-to-electricity Nanodevice Reveals How Earth’s Oldest Surviving Cyanobacteria Worked
An international team of scientists have unlocked a key piece of Earth’s evolutionary puzzle by decoding the structure of a light-harvesting “nanodevice” in one of the planet’s most ancient lineages […]
