Forensic Science is rapidly progressing to the point that the science fiction of today could well be the science reality of tomorrow. Expert Author: L.Stalin Hair follicle drug testing is the ultimate drug testing method due to its large detection window, convenience and accuracy. This article talks about the basics of hair drug testing, how the hair follicle test work and produce results for drug use detection. Expert Author: Dr. Randy Wysong Evolutionists use probabilities to prove that life could have emerged on Earth by chance. Not only are such probabilities in the realm of impossible, scientific laws demand that probable events happen, not impossible ones. Expert Author: Dr. Randy Wysong Materialists believe that all the energy and matter in the universe is governed by physical laws. Since evolution presumes materialism is all there is, and denies the quite evident presences of free will their foundation crumbles. Your free choice to believe in evolution would be the very act that denies its validity. Expert Author: Phil Morris The first metal detector was created in 1881 by Alexander Graham Bell to detect the bullet lodged in the body of President James Garfield when he was assassinated.

Expert Author: Michael Russell The seasons of the year are integral to the survival of most life on earth, affecting migratory patterns, spawning and hibernation among many other factors, but what exactly causes these yearly climatic changes? Expert Author: Dave Conrad Mechanical energy is an area of science that is making strides every day. The study of how actuators produce mechanical motion by converting various forms of energy into mechanical energy is a source of great exploration. Science finds new ways to make use of actuators every day including for medical purposes. Many scientists believe that the more they study these seemingly simple machines, the more they will discover ways of helping mankind. Expert Author: Dalvin Rumsey On all modern vehicles there is a computer that controls the way the engine operates, this computer is called Electronic Control Module, or ECM. The purpose of the ECM is to maintain the engine running within emissions limits and at top efficiency. With the very strict emission regulations of today, this is not an easy task to achieve. Precise and constant adjustments to match various conditions of the engine must be made by the ECM in regards to speed, load, engine temperature and others. Expert Author: George Johnson One thing we can always be certain of is our advancement in technology. Ever since that first trip to the moon, our curiosity has more than heightened. We now have the ability to achieve satellite images of earth.
This has given the human race an incomparable new take on space and how the earth fits into the scheme of things. With the satellite technology we currently enjoy on a daily basis, anything seems possible, and nothing out of our reach. Expert Author: Analeese Burnabaker There is so much to be learned in life, sometimes I find myself overwhelmed with all that I do not know. I've heard it said, however, that the smartest people are the ones that know that they do not know much. I like that. I like it because I am acutely aware that there is so much that I have yet to discover and understand. I am committed, however, to the process of constantly learning more. Expert Author: Michael Russell Is there life on Mars? If there is, they probably don't want uninvited guests. Hoping to find life shouldn't be a reason to ignore the lives in front of you.

Expert Author: Susan Green A microscope is a device which allows one to view something which is too small to be seen by the naked eye. Items which are often studied under a microscope can include a single hair, blood or skin cells. With the naked eye these are hard to see, and impossible to view in any detail. However, by using a microscope the intricacies of these and any other object are much more clearly revealed. Expert Author: George Royal One of the most important telescopes in the history of astronomy, the Hubble telescope has allowed observers to peer farther into space than any previous telescope. By moving outside and above the atmosphere of the earth, the Hubble telescope has been able to observe visual data much more clearly than a terrestrial telescope, and it has been able to see much farther into the ultraviolet and infrared spectrums as well, since these spectra are largely absorbed by the earth's... Expert Author: Sebastian Romero If you want to trace your ancestors, the job is much easier with modern DNA analysis techniques. The process is very simple. You register and pay a fee. The company sends you a mouth swab kit. You use it and send it back to the lab for analysis. Cells from your mouth swab will contain your DNA. Expert Author: Dora Wysocki Raising price of oil, gas and other commodities brings on the surface the question about utilizing other resources of energy like of solar energy. This article represent a brief discription of solar panels.
