Bacterial spore coat protein kinases: A new twist [Biochemistry]>

Edit PNAS 21 Jun 2016
“Plus ça change, plus c’est la même chose” (the more things change, the more they stay the same). Nowhere is this more apparent than in biology, where nature cleverly recycles and adapts the same chemical reactions to control complex physiology from bacteria to archaea, plants, and metazoans (1, 2). However,... ....

Cells that made humans possible evolved via 'long, slow dance'

Edit The Times of India 18 Jun 2016
The first eukaryote is thought to have arisen when prokaryotes - the kingdoms of archaea and bacteria - joined forces ... The eukaryotic cells of plants, animals, and protists are markedly different from those of their single-celled, prokaryotic relatives, the archaea and bacteria....

Life as we know it most likely arose via 'long, slow dance'

Edit Science Daily 17 Jun 2016
The first eukaryote is thought to have arisen when simpler archaea and bacteria joined forces. But researchers now propose that new genomic evidence derived from a deep-sea vent on the ocean floor suggests that the molecular machinery essential to eukaryotic life was probably borrowed, little by little over time, from those simpler ancestors ... ....

Seeing red (UNSW - The University of New South Wales)

Edit Public Technologies 17 Jun 2016
Its breakthrough application, however, is the result of an elaborate cross-disciplinary UNSW study into the nature and interactions of methane-producing microbes, or 'methanogenic archaea' ... The India-based project is also expected to deliver new fundamental knowledge about how the methane-producing microbes, known as 'archaea', work he says....

Unexpected origins of photosynthesis (INRA - Institut National de la Recherche Agronomique)

Edit Public Technologies 13 Jun 2016
(Source. INRA - Institut National de la Recherche Agronomique). The conversion of light solar energy into chemical energy, a process named photosynthesis, is one of the most important biological reactions on earth ... Photosynthesis is the origin of the fossil energy and organic matter available on earth today ... Indeed, one of the sequences is predicted to derive from alpha proteobacteria while the other one is closer to Archaea ... (noodl....

Man Dies After Falling Into Yellowstone Hot Spring

Edit IFL Science 09 Jun 2016
A man has died at Yellowstone National Park after tumbling into a hot spring after wandering off the designated path ... Mr ... Under high pressures and at incredibly high temperatures, this incredibly acidic groundwater is then forced skywards at remarkable speeds as a geyser; at lower pressures, it emerges through so-called hot springs, which are home to thermophilic microorganisms known as archaea ... ....

Targeting metals to fight Staphylococcus aureus (French Alternative Energies and Atomic Energy Commission)

Edit Public Technologies 30 May 2016
(Source. French Alternative Energies and Atomic Energy Commission). ​​The so-called biologic metals are necessary for life ... Researchers have now identified a new metal scavenging molecule produced in the bacterium Staphylococcus aureus and baptized it staphylopine ... The discovery of a similar metal scavenger in the three kingdoms of life (archaea, eukaryotes and now bacteria) suggests an ancient origin for this type of molecule. ​Figure 1....

The Selfish Gene turns 40

Edit The Guardian 29 May 2016
In 1976 Richard Dawkins’s study of evolutionary theory became the first popular science bestseller. How do its ideas stand up today?. It’s 40 years since Richard Dawkins suggested, in the opening words of The Selfish Gene, that, were an alien to visit Earth, the question it would pose to judge our intellectual maturity was ... The idea was this ... We share dozens of genes with our most distant relatives, single-celled bacteria and archaea ... ....

Extreme Methane-Producing Microbes Found At Earth's Surface Hint At Life On Mars

Edit IFL Science 25 May 2016
These methane-detecting organisms likely belong to the archaea domain, single-celled microorganisms that, despite having similar ecological roles to bacteria, are in fact physiologically distinct ... This new microbial discovery suggests that it’s possible that archaea at or near the Martian surface, perhaps within patches of high-pH water, may be responsible for pumping methane into the atmosphere instead....

Antibiotic Cow Farts Contain More Methane

Edit IFL Science 25 May 2016
In the meantime, the researchers hypothesize that tetracycline allows a type of microorganism called archaea to thrive in the cows’ intestines by killing off other bacteria with which these single-celled creatures normally compete for hydrogen. Since archaea release large quantities of methane as a by-product of their metabolism, any increase in their population results in significantly beefier cow farts and cowpats ... ....
