As a former athlete and runner, I am certainly no one who would ever be a spokesperson for a tobacco company. I value my lungs and their ability to produce oxygen for my body, I don’t want anything to happen to them, nor do I want anyone else’s lungs to […]

The Components of the Blood and the Immune System
We all have a general idea of what blood is. The heart pumps it through our body, and we need it to live. It is used to swear eternal friendship. We use it to save lives. If we are sick, the doctor can test our blood to find out what […]
Gene Assembly: DNA Sequencing of Gene-Sized Fragments Using Primer Walking
Next Generation (Next-Gen) sequencing is a new form of technology capable of determining the sequence of DNA the size of a bacterial genome. Despite this capacity to sequence millions of bases, Next-Gen technology is not always efficient or cost effective. Sequencing smaller fragments of DNA is an example of this. […]
The Human Species and The Genetics of Echolocation Speculated
Not long ago, I had an interesting conversation with a gentleman who explained he’d observed his own personal abilities to use the background and ambient noise to help him navigate in a dark hallway in pitch black conditions. After he did this a few times he realized that if he […]
Can Terrestrial Life Have Extraterrestrial Origin?
Crick (1973) advanced the idea that life was originally seeded on Earth from space – the idea of Panspermia. The British astronomer Fred Hoyle and Srilankan Chandra Wickramsinghe have further raised the possibility of Panspermia (1981). The whole idea of Panspermia is the outcome of inability to satisfactorily explain origin […]
Auto Refractometers
Discover a new range of constructive refractometers, in the marketplace named auto refractometers widely used as an ophthalmic diagnostic product allowing a more natural measurement. An auto refractor or automated refractor is a computer-controlled machine used during an eye examination to provide an objective measurement of a person’s refractive error […]
Historical Development of Automated Sequencing Using the Sanger Method
Automated sequencing has been a technique utilized since the early 1980s. Although the technology has changed dramatically since its first use, the basic chemistry is still commonly used today. It is based on four basic steps: purification of DNA, amplification using the polymerase chain reaction (PCR), separation by electrophoresis and […]
How to Study Biology to Get an A-Plus
Biology is the study of life in its entirety. The growth of biology as a natural science is interesting from many points of view. One feature of this growth is changing emphasis. Initially it was description of life forms, identification, nomenclature, classification of all recorded life forms. In recent years, […]
One Person, Twelve Bodies
It is obvious that all human beings go through various cycles during their life, progressing from infant to child to adolescent to adult to senior citizen. Each of these stages builds upon previous biology and experience while evolving from one to the next. The concept that the body changes form […]
