Science Articles & NewsHow Electron Microscopes Work Electron microscopes are among the most powerful magnifying tools on the planet. They use beams of electrons rather than conventional light to illuminate objects. The two main types of electron microscopes are transmission electron microscopes and scanning electron microscopes. Ernst Ruska and Max Knoll constructed the first electron microscope in 1931. They needed an instrument that could examine tiny specimens like components of cells, and conventional light microscopes were not nearly ... Invaluable Embryonic Stem Cells Research Embryonic Stem Cell (ESCs) Research is back in the news again. Unfortunately, it is under the political and religious pressure. ESC is moving at a slower pace at the expense of, as stated by the White House, "millions of people who suffer from life destroying diseases." Unlike abortion, the purpose of ESC research is to cure potential diseases and disabilities such as Parkinson's disease, diabetes, Alzheimer's, stroke, and spinal cord injuries. The History Of The Microscope The first microscope was created hundreds of years ago. In the passing centuries, microscopes evolved into powerful, precise tools that allow scientists to view tiny objects at a level of detail that seems unreal. There are a wide array of available microscopes, from the compound microscopes commonly found in high school science classrooms to powerful scanning tunneling and electron microscopes used by Nobel Prize winners. Building A Foundation, Starting With Physics When you break it down, all sciences are derived from physics. Think about it, psychology is the biology of the brain. Biology is just the study of biochemical reactions. Biochemistry(or organic chemistry) is simply complex chemical reactions. Chemistry is just molecular physics summed up into a table(The periodic table). Finally, molecular physics is defined by the weak nuclear force of the fundamental forces of physics. Even the four fundamental forces of physics can be broken down into one ... Recognix: Face Recognition Technologies - Bringing Home The Future. You have seen it in the movies but now it is real, face recognition access control systems are no longer a bright idea for the future; it is already here for your home & office. Telescopes, Principle Of Operation And Factors That Affect Its Properties Telescopes are devices that are used to view the distant objects. They find its use in astronomy and physics. It enables you to view the distant objects by magnifying them. There are many types of telescopes and their prices vary according to the specifications. Many accessories are also available that can be used in conjunction with the telescopes. Small telescopes that are used as toys are also capable of viewing some objects around 50 meters away. Principle in which the ... Accurate Pre-neolithic Calendars Braden is quite wrong when he says the initiations to this knowledge began about two thousand years ago. I think that is when some people emboldened by the earlier Pythagorean partial inclusion of the knowledge into Therapeutae systems like the Essenes, started to study it and write something about it. However, the prohibition on sharing this information which is said to have still been a matter of summary execution in the time of Plato, probably started ten thousand years earlier. Geothermal Energy In Australia GEOTHERMAL ENERGY IN AUSTRALIA Geothermal energy might hail as an alternative source of energy to drive our turbines in a race to produce “cleaner” electricity. The Harmonic The Harmonic In a good history book by a leading light in the field of history, I recall Michael Grant saying Pythagoras was ‘weird’. This book is The Rise of the Greeks and he does almost admit he is not qualified to judge the great sage, which is more than many academics will allow. None of us should expect he could judge ‘bi-location’ or the musical octaves and their connection to the Singing of the Spheres. However, it would be nice to see these researchers (are ... Cord Blood and Its Uses Cord blood is the blood left in the umbilical cord and placenta after the birth of the child and is collected after the cord has been cut off. The umbilical cord is routinely discarded with the placenta after a child is born. It is also called placental blood. Cord blood has lots of blood producing stem cells which can be frozen and later used for transplants. Cord blood is genetically unique to the child and the family. Now researchers have found that it can be used to treat many ... The Intricacies of a Compound Microscope Have you ever used a compound microscope? Your first thought may be to answer "no" but chances are if you had Biology in high school or college that you have used a compound microscope. What do you remember about this microscope? You may remember what it looks like but can you recall how it worked? If not, this article is for you! Ancient Navigation and Mapping DR. SENTIEL ROMMEL: As part of the research team that sought to know how advanced the ancient navigational equipment and computers or astrolabes were, this man deserves credit he has not received; although it might be that credit would come in the form of ridicule such as was directed at Barraclough Fell. Here is an excerpt from The Epigraphic Society Occasional Publication no. 20 on pages 2-3 which makes mention of his assistance in these regards that prove Maui was not the ... Lasers - The New Mythical Gift Of Fire Copyright 2005 by Doug Smith In Greek mythology, the Titan Prometheus gave the gift of fire to Humanity. It provided warmth, light, and energy. Whether or not you believe that myth, humanity has learned to concentrate that light into beams of unimaginable power: Lasers. What does that word make you think of first? Science fiction ray guns? A secret agent strapped to a table while a metal- melting beam of light inches toward him? Or maybe the master thief throwing dust in the air to reveal a ... The Harmonic (logos Etc.) The Harmonic In a good history book by a leading light in the field of history, I recall Michael Grant saying Pythagoras was ‘weird’.

A Cluster Of Atoms Imagine a new variety of compounds; compounds that have properties never seen before or simply compounds that have properties more pronounced than those which we already know of at present. It would be really cool. No, in fact it is really cool! Indeed, an entirely new class of compound is on the verge of getting everybody’s attention. The beauty Of Number Theories In the proceedings of the London Mathematical Society of May 1921, Srinivasa Ramanujan said something startling as a reply to G.H. Hardy’s suggestion that the number of a taxi-cab (1729) was “dull.” Ramanujan’s reply was as follows: “No, it is a very interesting number; it is the smallest number expressible as a sum of two cubes in two different ways.” Is Yawning Contagious? It is a fact to any observer that yawning flies like a butterfly and stings like a bee. Scientists and others studying yawning, seem to have reached that same conclusion. Yawning is indeed contagious. But why? How Did Dna Testing Children Begin? The story behind the first maternity and paternity tests used for legal purposes. Science Behind Using An Electric Fan Electric fan once was an essential heatstroke prevention item in summer for many families. Though the number of families that use electric fans has somewhat decreased due to the popularity of the air conditioner, staying in an air conditioning room for too long can cause the immunity of our body to drop, some can easily catch cold, get a fever, contract allergic rhinitis and allergic asthma, and more. These are all because of the bad air quality caused by almost no circulations in an air ... Life Under Mars Ice Shelf? When looking for life on Mars we should be thinking of how life forms on Earth. Not because it will be similar, although it possibly could be, but because we know the things, which inhibit life and the things which help it flourish. This is not to say that life does not exist inside the rocks or under the surface in underground aquifers or that the rocks themselves are not alive, but in all probability we will find the life or remnants of previous life in those places where we find life on ... The Big Bang Theory - Evidence Start Of Cosmos And Human Evolution The Big Bang Theory - Evidence Start of Cosmos and Human Evolution What is The Big Bang Theory! What do we mean when we talk of The Big Bang Theory? In Concept The Big Bang Theory would mean something related to the start of the Cosmos... the beginning of the Evolution itself. The Big Bang Theory came to be accepted by scientists only about three decades ago as an irrefutable fact of Creationism. Does it mean that it is only The Big Bang Theory which gave birth to the existing Cosmos? Yes! ... The How To Of Pyramids GEOPOLYMERIZATION: I just watched a show dealing with the Incan Andean cosmology that said they believed in 'As Above, So Below'. This is one of the three laws of the Magi and the Dictum of Hermes that our secret agent of British Intelligence has on the back cover of his book Secret Societies. Dr. Davidovits is the modern patent holder of many geopolymeric rock-making or concrete processes and I talked at length with his co-author Marjorie Morris in 1993-4 about a variety of ... Text To Speech - It's Simple Looking for a natural voice speech engine? Curious about what software can read your e-mails. Here is the latest TTS (text-to-speach) news. Statistical Analysis Of Hydrologic Variables Relation To Tree Ring Growth Statistical methods that may be utilized to determine hydrologic effects on indexed tree growth. The ability to determine the effects of multiple hydrologic and climatic variables such as temperature, precipitation, stream flow, and groundwater on the growth of the Western Sycamore requires the use of statistical regression methods and may require more complex methods such as multiple linear regression, factor analysis and Principal Component Analysis (PCA). A note about time scales Since the ... Ball Bearings Are Flat - Another Myth Crushed Ball Bearings Are Flat – Another Myth Crushed Incredible but unrelated things I learned working on the Internet By David Leonhardt Immortality : My Ultimate Aim Immortality has always lured me. Immortality is not just living indefinitely but is to keep struggling to be alive. It means, you cannot die of natural factors but you can however die of you following beings e.g. someone switching off your simulation on a chip without you capable of doing anything coz you have not updated yourselves with the times and the environment you are living in. Is 'Thought' Evident in Plants? Who would have thought that a plant could be a witness to a crime – and even testify against the perpetrator? Well, it is true! In the early 1970’s experiments were done on ordinary houseplants, by researchers who connected a polygraph machine to a plant. Living In Arizona Boulders Where Did They Come From? When most people think of building a secluded home, they think of tall trees and large bushes. But what about boulders? DNA Testing Has Changed Everything Since its discovery 20 years ago, the use of DNA for human identity and relationship testing has emerged as a powerful tool in both civil and criminal justice systems. DNA testing can reveal whether two or more individuals are related as well as determining the nature of their relationship. Today, it is possible to identify people by a single hair, as well as obtain information about their gender and ethnic background, and, within the next couple of years, identify their age. DNA Testing Breaks Down Barriers in the Court Room DNA testing has three major applications for forensic studies: identification of missing persons; identification of victims of wars, accidents, and natural disasters; and crime investigation. Annually, more than 20,000 forensic DNA tests are performed in the UK. Two out of three of all criminal cases using DNA evidence involve sexual assault, the rest are cases dealing with burglary, murder, and other types of violent crime. During the last 15 years, DNA analysis became an indispensable ... |
