Ancient microbes discovered in bitter-cold Antarctic brine
Where there's water there's life – even in brine beneath 60 feet of Antarctic ice, in permanent darkness and subzero temperatures.
Researchers discover unknown species at juncture where hot and cold habitats collide
Among the many intriguing aspects of the deep sea, Earth's largest ecosystem, exist environments known as hydrothermal vent systems where hot water surges out from the seafloor. On the flipside the deep sea ...
First detailed report defines limits of methane-exhaling microbial life in an undersea volcano
By some estimates, a third of the Earth's organisms by mass live in our planet's rocks and sediments, yet their lives and ecology are almost a complete mystery. This week, microbiologist James Holden at the ...
Life thrives in porous rock deep beneath the seafloor, scientists say
Researchers have found compelling evidence for an extensive biological community living in porous rock deep beneath the seafloor. The microbes in this hidden world appear to be an important source of dissolved ...
Banded ironstone formation theory challenges current thinking
A UWA geologist has proposed a hypothesis which threatens to overturn conventional notions of the way Banded Ironstone Formations (BIF) first evolved.
Billion-year-old water could hold clues to life on Earth and Mars
A UK-Canadian team of scientists has discovered ancient pockets of water, which have been isolated deep underground for billions of years and contain abundant chemicals known to support life.
Glimpse into the future of acidic oceans shows ecosystems transformed
Ocean acidification may create an impact similar to extinction on marine ecosystems, according to a study released today by the University of California, Davis.
