Human Stem Cell Medical - Legal Implications

Biotechnology is still developing and requires rigorous evaluation and regulation before it can be safely accepted. With the present divided opinion among the scientific community and the absence of biosafety standards…

The idea that being a dental hygienist can help save lives seems exaggerated, but according to a recent article in Cosmos Magazine, it is a very real possibility. Merolla (2010) reports that researchers have recently…

Earthworms are seen in a broad range of habitats across the world as they easily adapt to a lot of different types of soil as also lakes and streams. These worms are found to be advantageous to the soil in a number of…

There are many studies which suggest that nutrition is inextricably linked to cancer rates and many of those studies with their findings will be reviewed during the course of the present study.

In the early days of Ufology, researchers appeared too eager to verify sightings, which they then interpreted as evidence of 'nuts and bolts' spacecraft piloted by intelligent EBEs. Like numerous deities and other extraterrestrial visitors, EBEs are generally held to be concerned about human conduct. This concern was widely reported in the spate of UFO sightings after the Second World War and the beginnings of the nuclear age. Sensationalist reports merging with Hollywood fantasy led to a distancing of orthodox science from Ufology. Explanations offered by Ufologists frequently ignored Occam's razor, which is a rule against multiplying entities or - in general terms - a rule which says don't involve extraordinary hypotheses until the ordinary ones have been eliminated. The apparent resistance to falsification also contributed to Ufology's lack of credibility. However, modern Ufologists, such as Jenny Randles and Paul Fuller of the British Unidentified Flying Object Research Association (BUFORA), are strict adherents to Popperian-inspired scientific methodology, enthusiastically seeking to falsify EBE explanations and providing explanations which are acceptable to orthodox scientific opinion. In this respect the modern Ufologist is a debunker rather than a myth-spinning believer. Explanations in terms of atmospheric phenomena, hallucinations or hoaxes are generally expected from BUFORA publications. Over the years the BUFORA standpoint has been vindicated. So much 'confirmatory' evidence has been demonstrably unreliable. Photographs, which were once considered as hard evidence, are now held to have zero credibility because of the likelihood of fakes. With the advent of sophisticated image-manipulation computers whose work is undetectable, photographs unsupported by other reliable confirmatory evidence are unacceptable. Eye witness reports are also problematic as they are frequently influenced by psychological and cultural factors.

Clostridium tetani is an anaerobic pathogenic bacterium that is primarily found in soil and animal intestinal tracts. As characteristic of all bacteria, C. tetani bacteria are single-celled and do not contain any membrane-bound organelles, such as a nucleus. This bacterium is Gram-positive, meaning it lacks an outer lipopolysaccharide membrane and possesses only a thick peptidoglycan cellular wall. However, established vegetative bacterium occasionally stain Gram-negative, indicating a development of a thin

In very general terms, forensics can be defined as the application of science to law. (a Career in Forensic Science: What is Forensic Science?) Forensics is usually referred to in the context of criminal cases and…

The essence of any effective marketing plan is to seek out opportunities for a unique, defensible, differentiated market position (Bronnenberg, 2008). Toothpaste that through its unique chemical properties can also…

It is easy to assume that all life on earth require a delicate and forgiving environmental balance. Oxygen, water, and moderate temperatures are key to the survival of most organisms.
