Nano springs eternal; Protozoan 'engine' posts nano records
Looking through his handmade microscope in 1702, it was Anton van Leeuwenhoek who first described the workings of a nano machine. He observed the rapid contraction of a stalk tethering the cell body of a tiny protozoan, Vorticella convallaria, to the surface of a leaf. Little did van Leeuwenhoek imagine that more than 300 years later, the biological spring that drives Vorticella would set records...Protein 'nanosprings' most resilient found in nature
A component of many proteins has been found to constitute one of the most powerful and resilient molecular "springs" in nature, researchers have discovered. The engineers and biologists from Duke University and the Howard Hughes Medical Institute say their discovery could lead to a new understanding of mechanical processes within the living cell. The discovery also could provide potent nanoscale...From hot springs to rice farms, scientists reveal new insights into the secret lives of archaea
In the world of microbes, as in politics, some groups just can't seem to shake the label ''extremist.'' So it is with archaea (ar-KEY-uh), a collection of bacteria-like microorganisms whose unique genetics and chemical structure separate them from all other living things. For years, biologists have pigeonholed archaea as extremophiles-creatures that live in extreme conditions. Indeed, many...Bacteria Commonly Seen In Radioactive Waste, Hot Springs Found Inside Humans
A group of bacteria, previously known to exist in radioactive waste, hot springs and fecal matter of animals has now been found to reside inside the human stomach. // This finding could eventually pave for a better understanding of gastrointestinal diseases and newer treatment strategies. The bacteria 'Helicobacter pylori', that was discovered about 20 years ago, has been largely blam...Schlesinger Laminectomie Rongeur, golden springs
