Over the recent years, DNA Testing has increasingly become popular in the fields of Biomedicine and Biotechnology, Criminology and Family Law. DNA Testing has the ability to determine biological lineage and genealogical links, settle estate disputes between family members. DNA testing can also identify criminals based on biological evidences present in a crime scene. Thus, people are becoming more and more interested in learning and discovering about DNA Testing and how it can help affect and shape individual lives across the world.

How is DNA testing relevant to modern lives?

1.Relationships

DNA testing can determine whether or not two people are related. And if they are indeed related, DNA Testing can give a certain percentage to which these two people are linked biologically. DNA testing can also tell you whether or not you are relatives with a person of the same surname. Thus, DNA testing proves and disproves family tree researches.

2.Ancestry

DNA testing can trace lineages. They determine if two or more people are descendants from the same ancestor. It matters not how far the distance between you and a alleged ancestor could be. As long as there are biological specimen from your and from the alleged ancestor (hair, semen, saliva, buccal cells), ancestry can still be established. Ancestry tracing through DNA testing are most often used by offspring of people who have migrated to other places for many years but who would still like to find their roots in their parent’s country. Hence, DNA testing can also provide you with your ethnic origins.

3. Settlement of Disputes

Since DNA testing can prove and disprove the biological relationship between two or more people, DNA test results are also tools used in court to settle land and estate disputes, in the writing of wills, and in child custody cases.

4. Forensic Identification

Clearer than fingerprints, DNA test results are considered as today’s one of the most powerful tool in determining criminals based on biological evidences found in crime scenes. In rape cases, semen samples, skin scrapings, or suspect’s hair found in victim’s fingernails are used to determine identity of perpetrators.

As far as acquitting the innocent and charging the guilty is concerned, bridging peoples lives and settling domestic disputes, the constant complain against technology has found its justification in biomedical technology and DNA testing.

  • Hydrogen As a Fuel Source - By: Levi Quinn
    From water to air, there are a number of ways to energize your car. Alternatives to petroleum are a hot topic today. The growing concern for the environment is steadily increasing. It's an important issue that many people want to feel personally connected to. Hydrogen as a fuel source is not an entirely new idea. But science is taking a closer look at the impact that using hydrogen could have on both the environment and the economy. The best solutions are the ones that have more benefits than drawbacks.
  • MRI and Ultrasound: Two Vital Branches of Radiology - By: R Govindan
    Radiology was initially the branch of medical imaging that made use of x-rays on large flat sheets of photographic films for diagnosis. Modern day radiology is no longer confined to the practice of x-rays and now encompasses other methods of diagnostic imaging such as Computed Tomography (CT), Magnetic Resonance Imaging (MRI) and Ultrasound.

    Helena Petrovna Blavatsky (HPB) demonstrated the Siddhis (psychic-spiritual faculties) of clairvoyance, clairaudience, and the powers of projection, precipitation and being en rapport. These were all used in her writings on Occult science and Meta Physics which may be categorized into seven kinds of processes. We outline them below but it is emphasized that none of the above processes are miracles or supernatural

  • The Z-Boson Mass and its Formula as Multiple Proofs in One Bowl of Yummy Pudding - By: Sean Sheeter
    A demonstration of the mathematical, theoretical and, especially, empirical connotations of the phrase "Pudding Proof" in the context of a highly exacting physical model. In particular, a formula is given deriving the mass of the Z-boson from two heavy quarks and and Higgs field. Remarkably, the precise correlation with the known value of the Z-mass is thus empirically proof positive of these far less directly measurable masses, which is further supported by arithmetic and theoretic construct.
  • The Theory, Significance and Precise Calculation of Gluino Mass - By: Sean Sheeter
    A preview of the most significant predictable particle cascades at Cern's LH-Collider in the coming years. Describes how a precise gluino mass of 6.388355 TeV relates to the super-symmetric Higgs mechanism and decays to squarks and other 'sparticles as a prerequisite to creation of 'dark mass,' as well as the unsolved puzzle of material baryon creation. Which also goes on to shows why giving three dimensionless calculations for the gluino mass are central to the e-course "241-Mumbers."

    A history of a definitive answer to #1 'millennium question' of Strings 2000 in regard to whether all fundamental parameters can be determined in a dimensionless manner. Focus's on a 'pure' calculation of the fine-structure constant from a unified 'monolithic' system that allows precise equations for the full spectrum of fundamental particle masses from Higgs/SUSY to quarks, neutrinos and dark matter. With an update on controversies of determining the fine-structure from metric measures and a few other related issues.
  • Proof of the Exact Up and Down Quark Masses from the Pion Mass-Differential - By: Sean Sheeter
    A discussion of the equivalence of the mass differential between the charged and neutral pion as a function the mass difference between the down and up quark. Given the unprecedented mass value of the down quark = 7.763258 MeV, the up quark mass is calculable from the even more exacting d-u mass differential = 4.593453 MeV, where the experimental pion mass difference = 4.5936 plusmn.0005 MeV.
