Structures found on meteorite fragment Allan Hills 84001. Nanobacterium (/ ˌ n æ n oʊ b æ k ˈ t ɪər i əm / NAN-oh-bak-TEER-ee-əm, pl. nanobacteria / ˌ n æ n oʊ b æ k ˈ t ɪər i ə / NAN-oh-bak-TEER-ee-ə) is the unit or member name of a former proposed class of living organisms, specifically cell-walled microorganisms, now discredited, with a size much smaller than the generally ...
The term "nanobacteria" is sometimes used synonymously with ultramicrobacteria in the scientific literature, [2] but ultramicrobacteria are distinct from the purported nanobacteria or "calcifying nanoparticles", which were proposed to be living organisms that were 0.1 μm in diameter. [9]
This list of laboratory biosecurity incidents includes accidental laboratory-acquired infections and laboratory releases of lethal pathogens, containment failures in or during transport of lethal pathogens, and incidents of exposure of lethal pathogens to laboratory personnel, improper disposal of contaminated waste, and/or the escape of laboratory animals.
A biological hazard, or biohazard, is a biological substance that poses a threat (or is a hazard) to the health of living organisms, primarily humans.This could include a sample of a microorganism, virus or toxin that can adversely affect human health.
For example, supposed thyroid lines were actually melanoma cells, supposed prostate tissue was actually bladder cancer, and supposed normal uterine cultures were actually breast cancer. [1] This is a list of cell lines that have been cross-contaminated and overgrown by other cells.
The health and safety hazards of nanomaterials include the potential toxicity of various types of nanomaterials, as well as fire and dust explosion hazards. Because nanotechnology is a recent development, the health and safety effects of exposures to nanomaterials, and what levels of exposure may be acceptable, are subjects of ongoing research.
Costco has issued a recall for a cold and flu medication, sold at its stores at the end of 2024, over concerns of contamination.. The retail giant, in an advisory issued on Jan. 2, said Kirkland ...
Peer-reviewed research if possible. Direct quotes would be good. For example: A paper published in 2000 by a team led by a dentist John Cisar USNIH hypothesized that the "self-replication" was, in fact, an unusual form of crystalline growth, and that his contamination may have been the source of the DNA.
