“Fairly sophisticated” bacterial communications pose stark question re evolution
| August 1, 2018 | Posted by News under Cell biology, Complex Specified Information, Evolution, Intelligent Design |
From ScienceDaily: A concept known as ‘percolation’ is helping microbiologists explain how communities of bacteria can effectively relay signals across long distances. Once regarded as a simple cluster of microorganisms, communities of bacteria have been found to employ a strategy we use to brew coffee and extract oil from the sea. Percolation helps the microscopic […]
Bacteria make complex antibiotics that give chemists “cold sweats”

From Josh Bloom at American Council for Science and Health: I recently wrote about three of the deadly neurotoxins being produced by cyanobacteria (aka blue-green algae) during an ongoing algae bloom in South Florida (See Florida’s Deadly Algae Bloom – Why Is It So Dangerous?). The toxins range from structurally simple and easy for organic […]
Bacteria created iron deposits by metabolizing iron?

Researchers: Half of iron atoms in some cores were processed by microbes 2.5 bya/Clark Johnson 2.5 billion years ago? That’s the theory here: These ancient deposits, up to 150 meters deep, were begging for explanation, says Johnson. Scientists thought the iron had entered the ocean from hot, mineral-rich water released at mid-ocean vents that then […]
