Nanobacteria are said to have a hard mineral shell, replicate like a living organism and are wiped out by antibiotics and radiation, yet seem to lack DNA. This proposal was controversial to say the least, and has been described as the cold fusion of microbiology. So, are nanobacteria fact or fiction? A recent article in PLoS Pathogens takes a highly skeptical view (Nanobacteria: Facts or Fancies? 2007 PLoS Pathogens 3, 5, e55).. Nanobacteria have been claimed to be present in animal and human blood and other body fluids, in tissue culture cell lines, wastewater, rocks, in the stratosphere and in meteorites from Mars (Nanobacteria-like calcite single crystals at the surface of the Tataouine meteorite. 2003 PNAS USA 100: 7438-7442). Most of the reports are based on the visualization of nanobacteria by electron microscopy, but Kajander and his colleagues claim they can be propagated in cell-free tissue culture media (unlike viruses, which are obligate parasites requiring host cells for ...

A brief history of nanobacteria and their implications for human health. I remember when nanobacteria were a really big deal. Press-conference-by-POTUS-about-evidence-of-extraterrestrial-life-level big deal. I hadnt thought much about them until recently, when they made a surprise appearance in a presentation on idiopathic preterm birth by Irina Buhimschi, MD, director of the Center for Perinatal Research at The…. read more ...

Calcifying nanoparticles (CNPs) (nanobacteria, nanobacteria-like particles, nanobes) were discovered more than 25 years back; nevertheless, their nature is obscure still. important function in etiopat... Read More ...

One of the original discoverers of nanobacteria (NB) and NASA researchers have presented evidence supporting the role of the mysterious agent in kidney stone formation. If further studies confirm the results, a better treatment for this painful condition may include antibiotics. Finnish researchers first forwarded the idea of NB as a novel life form and…

Placenta can be considered as a pump of calcium necessary for the normal development of the fetus. We believe that the location of this pump is in the placental basement membrane. The calcification of this membrane has been described only in cases of in utero fetal death. In this study we describe for the first time a case of placental calcification in a living fetus. The fetus of a normal 21-year-old pregnant woman showed heart abnormalities but the genetic analysis showed a normal male karyotype. The histology of the placenta demonstrated multiple intravillous linear and granular calcific incrustations The hemtoxylin/eosin stain of the sections revealed basement membrane calcific incrustations and intravillous calcium deposits. We postulate that the fetal circulation in the villi was impaired and the calcium that reached the villi from the mother was deposited at this level ...

The ability of proteins and other macromolecules to interact with inorganic surfaces is essential to biological function. The proteins involved in these interactions are highly charged and often rich in carboxylic acid side chains1-5, but the structures of most protein-inorganic interfaces are unknown. We explored the possibility of systematically designing structured protein-mineral interfaces, guided by the example of ice-binding proteins, which present arrays of threonine residues (matched to the ice lattice) that order clathrate waters into an ice-like structure6. Here we design proteins displaying arrays of up to 54 carboxylate residues geometrically matched to the potassium ion (K+) sublattice on muscovite mica (001). At low K+ concentration, individual molecules bind independently to mica in the designed orientations, whereas at high K+ concentration, the designs form two-dimensional liquid-crystal phases, which accentuate the inherent structural bias in the muscovite lattice to produce protein

PNNL staff scientist and co-author Uljana Mayer devised new tagging methods that enabled the team to isolate sufficient amounts of protein. The tags also allowed fast measurements of protein-mineral binding. The researchers supplied the protein with energy--directly as electrons or in the form of a natural cellular fuel called NADH--and only during binding detected charge-transfer from protein to mineral, through a combination of techniques that included FCS, or fluorescent correlation spectroscopy, and confocal microscopy. These yielded a fluorescence intensity trace whose brightness depended entirely on whether hematite was available to bind with OmcA in solution. No hematite, dim; hematite, bright.. How bright? The peak current, or flux, doesnt run long, just a few seconds, Squier said, but flux is at least as good as what you would find in the most efficient bioreactors, which rely on living bacteria.. Biological fuel cells, or biofuel cells, are not yet powerful enough to be ...

In 2004 a Mayo Clinic team led by Franklin Cockerill, John Lieske, and Virginia M. Miller, reports to have isolated nanobacteria in diseased human arteries and kidney stones. Their results were published in 2004 and 2006 respectively.[9][10] Similar findings were obtained in 2005 by László Puskás at the DNA Lab, University of Szeged, Hungary. Dr. Puskás identified these particles in cultures obtained from human atherosclerotic aortic walls and blood samples of atherosclerotic patients but the group was unable to detect DNA in these samples.[11]. In 2005, Ciftcioglu and her research team at NASA used a rotating cell culture flask, which simulates some aspects of low-gravity conditions, to culture nanobacteria suspected of rapidly forming kidney stones in astronauts. In this environment, they were found to multiply five times faster than in normal Earth gravity. The study concluded that nanobacteria might have a potential role in forming kidney stones and may need to be screened for in crews ...

How did life originate? This is not part of evolution. Even so, there are many explanations. Proto-life, such as nanobacteria, viruses, or prions, exist as transitionary stages. Even a simple salt crystal can replicate itself. And amino acids are widespread, even in outer space. How did the DNA code originate? There have been simpler versions of the DNA code, for example one that only uses Adenine and Guanine. How could mutations create the vast amounts of information in the DNA of living things? Richard Dawkins once ran a computer model in which a complex insect-like shape evolved from a single pixel. Evolution had billions of years and billions of generations to do this. Why is natural selection taught as evolution, when natural selection selects, but does not create? Mutations can add to the DNA code. Natural selection is the cumulative effect of mutations, and can create information. Evolution is simply the cumulative effect of natural selection. How did new biochemical pathways, which ...
