Y Chromosome and mtDNA - Linking Lives, Past and Present
Deoxyribonucleic Acid, most commonly known as DNA, has been cropping up again and again in the development of Biomedical Technology. DNAs, the blueprint of humans, are unique and inherent in each individual, even among identical twins. In a word, DNAs are like human fingerprints that identify each person, his roots and ancestry and his ethnicity among others.Read more…DNA Testing: How DNA Testing Has Shaped The Modern World
Over the recent years, DNA Testing has increasingly become popular in the fields of Biomedicine and Biotechnology, Criminology and Family Law.

As they say, it’s all in the genes!Read more…Choosing an Online DNA Testing Service
Unless you've been living in a cave for the last ten years, you're probably aware of the growing role of DNA testing in everyday life. From forensics to relationships to ancestry, DNA testing is changing the way we validate truth. One of the fastest growing areas of DNA testing is in the realm of DNA paternity testing.Read more…Embryonic Stem Cell Research: Overcoming The Ethical Barriers
With well-publicized declarations that embryonic stem cells may be the panacea for every disease and affliction that defies current medical treatments based on surgical procedures and drug-based therapies, vocal support for stem cell research continues to grow louder. Proponents emphatically state that such research could regenerate failing organs since they have the potential to “become nerve cells, muscle cells, heart cells and all of the other cells in the body”[1] and cure diseases and other afflictions such as Alzheimer’s disease, diabetes, macular degeneration and even blindness, multiple sclerosis, Parkinson’s disease and spinal cord injuries. In the rush to justify and promote this research ethical questions such as “Do embryonic stem cells represent a life, should ‘extra’ frozen embryos created through in vitro fertilization be used to establish stem cell lines, and does the end (potential for and even cures of debilitating diseases and afflictions) justify the means (human embryonic stem cell research even if the embryo is destroyed in the process)?Read more…The Sun In Space
The Sun is the star of our solar system. The Earth and all the other matter in the solar system including the other planets, comets, asteroids and dust all orbit the Sun which in turn makes up more than 99% of the solar system’s mass. Earth receives energy from the Sun in the form of sunlight, and it responsible for supporting life on this planet, the weather and the climate.Read more…Pollution in the Modern World Leads to Modern Problems
In this modern world as scientists produce new technology for the welfare of mankind it only results in new luxuries being produced. This attitude by people towards the environment is changing because they want more and more luxuries and they are destroying the environment for this reason.They use instruments like fridges, air conditioners etc that release C.Read more…Facts On Mercury
Mercury is the planet closest to the Sun. It is a dry, rocky world with an extremely thin atmosphere due to the radiation emitted from the Sun, which has burned away a large amount of it away. Mercury, being closest to the Sun, completes one orbit in 88 days; however, it takes 59 days for the planet to rotate as it spins very slowly on its axis.Read more…Biotechnological Ethics
Biotechnology is often a controversial field. Every time you hear of something being cloned, some religious group is speaking pout. The same situation applies to stem cell research and the mapping of the human genome.Read more…DNA Molecules
Deoxyribonucleic acid, or DNA, is the component containing the blueprint that specifies the biological development and composition of every form of life. Its general structure is in the form of a double helix and is primarily made up of nucleic acids. DNA is a polymer strand of nucleotides that contain sequences using genetic codes.Read more…Pure Essential Oils
Pure essential oils are known as the life force of plants. They are highly volatile, concentrated substances, which are extracted from the different parts of a plant such as flowers, leaves, seed, resin, bark, fruit or fruit rinds, stem and root. Only very little oil is present in most plants.Read more…Teach Your Kids Arithmetic - Division Shortcuts
The famous Greek mathematician Pythagoras (you know the one with that theorem) said, “Numbers have a way of taking you by the hand and leading you down the path of reason.” What Pythagoras was getting at, I think, is that numbers—by their very nature—permit us to do things which enable an understanding of the very universe and its intricate laws. Numbers have their roots in arithmetic, and a mastery of this field, particularly the operations of addition, subtraction, multiplication, and—yes that monster operation of division—will certainly pave a smooth road down that path of reason.Read more…Reading Faster Makes you Happy and Creative
Fast thinking, or "racing thoughts," is most commonly known as a symptom of the clinical psychiatric disorder of mania (and of the manic part of bipolar disorder or "manic-depression"). But, according to Princeton University psychologist Emily Pronin, most healthy people also have experienced racing thoughts at some point in time--perhaps when they are excited about a new idea they have just learned, or when they are brainstorming with a group of people, or even when they lie in bed unable to fall asleep. Pronin and her Harvard colleague Daniel Wegner decided to explore whether inducing people to think fast might lead them to feel some of the other experiences also associated with the manic experience.Read more…Astronomy Real Star Power
Astronomy has to be one the most humbling of all subjects to study. Just the thought of our universe, being like a grain of sand in a sandy shore of universes, is enough to make me want to crawl back under the sheets. Everything just seems so immense, andbeyond comprehension.Read more…Leather
Ever wonder what is leather, what are it's properties and how is it made. Here is a simple and concise discription of leather; how it made and what are it's properties.Read more…Uses of Calendar: From Then and Now

Six centuries before Galileo conducted experiments with falling bodies and three centuries before Roger Bacon began to advocate experimentation to test hypotheses, an Arab Muslim scholar born in what is now Iraq was conducting verifiable experiments to test ancient Greek ideas about light and vision. That scholar was Ibn al-Haytham. His use of experimentation was an outgrowth of his skeptical nature and his Muslim faith. He believed that human beings are flawed and only God is perfect. To discover the truth about nature, he reasoned, one had to allow the universe to speak for itself. By insisting on the use of experimentation to establish truth, Ibn al-Haytham earned himself a place in history as the first scientist.Read more…Mars Exploration Rover Mission - VRPresents Technology Revolutionizes the Way of Presenting Science with the Aid of Virtual Reality
Mars Exploration Rover Mission has provided a large amount of scientific data and high resolution images. The question is: how to present them and not to bore the common man? The answer has been found by Sciterian Technologies.Read more…All About Lasers
Short for Light Amplification by Stimulated Emission of Radiation, LASER is a mechanical device that produces a narrow beam of light with a well-defined wavelength, capable of traveling over vast distances. The essential difference between the light emitted by a LASER and that by an incandescent light bulb is that unlike the former, the latter emits light into a large solid angle and over a wide spectrum of wavelength.

- 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. - Camps that Grow the Science in You - By: Ron Victor
