Expert Author: Peter Vine A home DNA test kit is exclusively used in the sampling stage of a home based DNA paternity test. The key component in the kit is usually a pair of serrated cotton swabs, and some DNA free sample tubes. These two components allow the obtaining of the source material which will ultimately be used to determine the biological relationship of a child to the putative parents. Expert Author: CD Mohatta I am not against any scientific enquiry. I support science and I fully support the work of science in making living better for all of this. Expert Author: Polly Priester Graphology is the name given to the general subject of personality analysis based on handwriting analysis. Just as in Psychology there are various schools of Psychology - Behaviorist, Psychoanalytical, and so on - so too in Graphology. Expert Author: Paul Graham One may consider the hair as a person's crowning glory. In fact, most people spend hours in front of the mirror fixing their hair. Aside from making each one of us look good, the hair has yet another function you might be interested in. In today's modern world, there comes another way of detecting drugs in individuals. Yes, using the hair! And it is actually the most accurate method of detecting drug abuse in individuals. Expert Author: Trevor Rowell Tritium has been used since the 1930's to illuminate watches at night. This once Top Secret technology is now available to members of the public in a safe form using tritium vial light sources. Expert Author: Stephen White DNA testing was popularized only in recent years mainly due to having it extremely handy when it comes to high-profile criminal investigations as well as in paternity cases. DNA, otherwise known as deoxyribonucleic acid, is most commonly used in trying to prove the relationship of an individual to another person, that linking is aimed at trying to determine whether or not those two people are related or not. Expert Author: Jack Smith First, the stomach must store the swallowed food and liquid. This requires the muscle of the upper part of the stomach to relax and accept large volumes of swallowed material. Expert Author: Jack Smith All animals, fungi and humans are heterotrophs. A heterotroph is an organism that obtains their nutrition by breaking down organic molecules in foods. The digestive system varies depending on the type of organisms; Fungi have the simplest system and humans having the most elaborate. Like the digestive systems in all organisms, the digestive system of the human is vital for survival. Expert Author: Mike Strauss Theoretical cosmologists spend much of their time perfecting what is now known as the 'Big Bang' theory. This concept originates from ideas percolating in the minds of scientists, theologians and astronomers down through the ages. However, much of what they consider as proof for the 'Big Bang' is dependent upon uncontrolled experimentation that is molded to meet their expectations. Expert Author: Rick Chapo Water is used as a significant power source in many parts of the world. In fact, Norway uses it to produce 99 percent of its electricity. So, how does it work? Expert Author: Rick Chapo With massive rebate programs and tax credits being issued by state and federal governments, using the sun to generate electricity is very popular. So, how does it work? Expert Author: Greg Neyman No doubt you have heard the claims from young earth creationists about living fossils. A "living fossil" is an organism that is thought to have been extinct, and then it shows up alive on planet earth. Expert Author: Joe Goertz In both science and in technology, a battery is used as a type of device that is used to store energy, making it available for use in an electrical form. They consist of electrochemical devices, including one or even more galvanic cells. Expert Author: Paul Callis The first Space Exploration started in 1957 with the launch of the first artificial satellite, Sputnik 1, sent into space by the Soviets. Since ancient times people have dreamed of leaving their home planet and exploring other worlds not known to man. Every era through out history has had a belief as to what the "heavens" are made from. Expert Author: Steve Roensch The following four-article series was published in a newsletter of the American Society of Mechanical Engineers (ASME). It serves as an introduction to the recent analysis discipline known as the finite element method. The author is an engineering consultant and expert witness specializing in finite element analysis.

Expert Author: Mike Strauss Science has reached an enormous impasse. From biology to physics, astronomy to genetics, the scientific community is reaching the limits of understanding which often presage a complete rethinking of long-accepted theories. So characteristic of this new apex of modern arrogance is the inability to comprehend the obvious in physics: That we don't know what we are talking about. Expert Author: John Mclain Chemistry is generally divided into two broad branches: organic chemistry and inorganic chemistry. Other types of chemistry include physical chemistry, biochemistry, and analytical chemistry, with each field branching off into several specific subfields. Here's a brief description of the most common branches of chemistry.
