Think of a world where infertile, childless couples can go to a medical clinic, purchase cell replacements for malfunctioning cells in the reproductive system and, thus, bear kids; a world where people afflicted with degenerative diseases like Parkinson's and Alzheimer's Disease can replace their damaged cells and be cured again; a world where the crippled can get the much-needed cells to revive their spinal chord and walk again.

Those amazing medical and scientific feats are only the tip of the iceberg when the potential of human cloning is concerned. Developed to its extreme, human cloning can make disease and sickness, maybe even physical suffering altogether, a thing of the past.

There are two basic kinds of human cloning and, separately, each offers us a deeper insight as to the vast possibilities of this burgeoning new science. In reproductive cloning, a cloned embryo is implanted in a woman's uterus from where, theoretically, a normal baby develops that is genetically identical to the DNA donor. The second type of cloning, therapeutic cloning aims to provide replacement organs or tissue for people. The cloned embryo contains DNA taken from the transplant patient to ensure that the cloned organs are compatible with the person's immune system.

In the past decade, human cloning has taken great strides. To many, the biggest and most visible accomplishment in this arena was the successful cloning of two mammals: Dolly the Sheep in 1996 and Snuppy the dog in 2005. After six years, Dolly died in 2003 from non-cloning related conditions. Meanwhile, Snuppy, Time magazine's "Invention of the Year" in 2005, is alive and well.

In 2004 and 2005, Korean scientist Hwang Woo Suk, who headed the team that created Snuppy, shocked the science world when he announced that he had successfully cloned human embryos in his laboratory in Seoul. However, it was discovered that Hwang had fabricated evidence to back his scientific research. Following a thorough investigation, through, a panel of scientists pronounced that Snuppy was a legitimate clone and this achievement stands.

  • 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.
  • Processes Involved In Blavatsky's Writings and its effects - By: Edi Bilimoria
    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."
  • Derivation of the Pure Precise Fine-Structure Number and as a Ratio of Two Inexact Metric Constants - By: Sean Sheeter
    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.
