2. Trans Fats and Weight Loss November 19, 2008 I've mentioned butter and oils, but what about margarine? It is an unsaturated fat, made from vegetable oil, but it has been hydrogenated. That means hydrogen atoms have been added to each molecule to "saturate" it so it takes a solid form at room temperature. The added hydrogen atoms also make it more stable, so it is less likely to become rancid. Sounds good? Well, actually, no. This synthetic saturated fat is called trans fat and the news about it is bad. Long marketed as the low-cholesterol alternative to butter, margarine has recently had a lot of bad press. Most of it is based on a ... (read more) Author: Francis Adam

3. Antibodies for use in Biomedical Research November 21, 2008 Antibodies are an unmatched tool used in biomedical research since they attach with high similarity and specificity to an array of molecules - the majority notably peptides and proteins. They are used in proceedings where categorization, quantification, localization or confirmation of a protein is essential. For in-vivo therapeutic applications antibodies are used, due to their capability to bind firmly to a desired molecule. IDEC Pharmaceutical's Rituxan® for use against certain B-cell non-Hodgkin's lymphomas and Genentech's Herceptin® drug for precise types of breast cancer are few of the su...

7. Can Genetic Information Be Controlled By Lasers? October 24, 2008 DNA, the molecule that acts as the carrier of genetic information in all forms of life, is highly resistant against alteration by ultraviolet laser, but understanding the mechanism for its photostability presents some puzzling problems. A key aspect is the interaction between the four chemical bases that make up the DNA molecule. Researchers at Kiel University have succeeded in showing that DNA strands differ in their laser sensitivity depending on their base sequences. It has been known for many years that the individual bases that code the genetic information contained in DNA show a hig... (read more) Author: Shane Ennerson

8. The Fact You Do Not Know About Reverse Osmosis Water October 10, 2008 RO water basically mean water produced by the process of Reverse Osmosis. Osmosis in science basically is the process where 2 types of liquid being separated by a membrane, the specific molecule from four solvent will move from a higher saturation to a lower four until 2 sides reach the same saturation level, by the law of nature. So, the key term here is membrane (or filter) and the direction of the flow. By allowing only certain type of molecule (mainly water or H2O are of smaller size) to pass through in term of size and reverse the osmosis flow direction. So this can only be done by fo...

9. What Are Antioxidants, Really? October 07, 2008 The term antioxidant has been tossed around more and more lately and we'd like to know what it really means. What is so wrong with oxidants that we have to be so against them? One definition for antioxidant is any substance that reduces oxidative damage (damage due to oxygen) such as that caused by free radicals. Free radicals? Like Libertarians or something? So it's still not quite clear - hopefully we can make it a little clearer. What happens is that your body creates a molecule called a "free radical" as a natural by-product of oxygen use. A free radical is an oxygen molecule ... (read more) Author: Andrea Vahl

10. Cholesterol: Good or Bad? September 29, 2008 Let’s get something straight from the on start; cholesterol is an essential compound in humans and for that matter in the entire animal kingdom. The idea that the cholesterol molecule is ‘bad’ is just plain inaccurate. Animals use cholesterol as their building blocks for cell membranes and other structural components. Cholesterol is the basic structural building block for hormones and other molecules essential to humans. What is Good and Bad Cholesterol? In actuality there is only good cholesterol until there is an over accumulation of cholesterol in the artery cells and in th... (read more) Author: Gary Kenneth Archer

15. Antioxidants Can Help Fight Free Radicals July 30, 2008 Free radicals are the main focus of research when the uses of antioxidants are being researched. You have probably heard of these damaging free radicals and the problems they can cause in the body, but you might not know how they are formed. What a free radical is made of is molecules in our body that have an unpaired electron which makes them unstable. The free radical is attempting to become stable when it goes after another molecule in an effort to gain the missing electron. What it creates by taking the missing electron is another free radical. The damage to the body occurs when the c... (read more) Author: Vincent Platania

16. Oxford University gets 18% more light from LCDs July 24, 2008 The University of Oxford has developed a way to improve LCDs without complex drive techniques.

17. Bodybuilding: Nitric Oxide - NO - NO2 July 15, 2008 Nitric Oxide is a free form gas that is produced in the body and is used by the body to communicate with other cells in the body. To produce this gas, enzymes in the body break down the amino acid Arginine. Nitric Oxide is a molecule consisting of one atom of nitrogen and one atom of oxygen. The production of Nitric Oxide occurs when the amino acid L-arginine is converted into L-citruline through an enzyme group known as Nitric Oxide Synthase (NOS). The chemical process of conversion is shown in figure 1. What does it do and what scientific studies give evidence to support this? ... (read more) Author: Zack Fair

18. Einstein and the Laser July 13, 2008 Albert Einstein is sometimes said to be a key person for the invention of the laser. Similarly, his famous equation E=mc2 is sometimes called the key to the atomic bomb. Is that reasonable? In one of this most important publications (“Zur Quantentheorie der Strahlung”), Einstein has described the process of stimulated emission of radiation. This means that a photon hitting some atom (or ion or molecule) may not only supply energy to this atom in an absorption process, but also send an already excited atom back to a state with lower energy. In the lattter case, an additional photon is emit... (read more) Author: Shane Ennerson

19. Better Health Through Reverse Osmosis? 5 Reasons To Filter Instead June 30, 2008 Can your family achieve better health through reverse osmosis treatment of your tap water? The companies that sell home reverse osmosis systems seem to think so.
