New “fixed” bacterial Tree of Life looks like a cityscape

Seen from below: Professor Hugenholtz said the scientific community generally agrees that evolutionary relationships are the most natural way to classify organisms, but bacterial taxonomy is riddled with errors, due to historical difficulties. “This is mainly because microbial species have very few distinctive physical features, meaning that there are thousands of historically misclassified species,” he Read More…

“Fairly sophisticated” bacterial communications pose stark question re evolution

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 Read More…

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 Read More…
