The Artful Amoeba

Thank You, Domain Archaea …


… and thank you to the late, great Carl Woese, for my post about both — Archaea Are More Wonderful Than You Know — was a finalist in the Best Biology Post category in this year’s ScienceSeeker Blog Awards. If you are interested in learning more about Woese and Archaea, I encourage you to listen [...]

Archaea Are More Wonderful Than You Know


In the 1970s, an obscure scientist named Carl Woese (pronounced “woes”) was working on something apparently rather mundane: finding a way to classify bacteria. Though that may seem a straightforward task, bacteria had stubbornly resisted all previous attempts. The traditional method — looking at differences in appearance, structure, and metabolism and sort of eyeballing it [...]

For years, ripples at the surface of the Dead Sea hinted there was something mysterious going on beneath its salt-laden waters. But in a lake where accidentally swallowing the water while diving could lead to near-instant asphyxiation, no one was in a hurry to find out what it might be. This year, some intrepid divers [...]

Mars, Ancient Water, Deep Hydrogen, and Life


Two billion year-old water pockets and a revised deep hydrogen content are good news for Earth’s vast subsurface biosphere, and could offer clues to life on Mars and much further beyond. Excitement over the Curiosity rover’s recently reported detection of a ‘spike’ in localized atmospheric methane – persisting over a couple of months – is [...]

Millennia-Old Microbes Found Alive in Deep-Ocean Muck


A sparse community of microbes can persist for eons in the clay beneath the deep blue sea. When scientists drilled into the Pacific Ocean bottom and pulled up a long core of clay, they also pulled up microbes living on so little that it was hard for the scientists to tell if they were alive [...]
