The Use and Control of Biological WeaponsBy: Dr.Badruddin Khan | 26/10/2008 | Self HelpWe have heard of use of harmful or deadly chemical or biological agents as weapons of war. These agents can kill many people and are considered weapons of mass destruction. While chemical weapons are made up of poisonous chemical compounds, biological weapons use living microorganisms. Weapons that contain the poisonous chemical products of living organisms are known as toxin weapons and are sometimes classified separately. ATTACK OF THE CELL PHONE ZOMBIESBy: William Thomas | 22/03/2009 | CultureAre zombies real? You'd better believe it! In this excerpt from ZOMBIE NATION - a book in progress - I take a look at the cell phone culture and its effects on participants and bystanders alike. Cell Phone Protection against Virus and RadiationBy: sheldonkalnitsky | 20/04/2009 | BusinessThere are now predictable to be 208 million cell phone users in the U.S. alone, 1.9 billion all over the world. Scientists panic we might be on the verge of a health calamities of epidemic proportions. Power of Living Water, Biological Magnetism – How it WorksBy: Mayer Fitoussi | 04/08/2007 | Technology"due to electrical interference, satellites, cellular telephones and high pressures, water loses its given powers", such water sick or "dead" water has a negative influence on humans, animals and plants. However water that has undergone magnetized purification regains its natural abilities. Crops grow faster and richer, flowers bloom and grow better, rivers and lakes restore their natural qualities and are re-energized. Hairy Cell LeukemiaBy: Juliet Cohen | 12/09/2008 | Diseases & ConditionsHairy cell leukemia (HCL) is a rare cancer of the blood. It affects B cells, a type of white blood cell (lymphocyte). HCL is due to increase of a clonal malignant B cell that infiltrates the reticuloendothelial cells, mainly the bone marrow, resulting in bone marrow failure. New Generation Reproductive Technologies (stem Cell-nanotechnology)By: G.M. Wani | 12/02/2008 | ScienceInvited Lead paper presented at Indian Society for study of Animal Reproduction (ISSAR) Conference held at Agricultural University, Bunwashwar, Orissa – on 7th to 9th Dec, 2007. Interference With Cell-to-cell Signaling: a Potential Therapeutic Approach Against Vibrio SpeciesBy: Vijaya Baskar, P And Veera Ravi.a | 16/05/2007 | NatureBacterial biofilms are sessile communities with high cell density that are ubiquitous in natural, medical, and engineering environments; they are fascinating since they are primitive tissues with an advanced chemical communications network. Currently, there is an explosive amount of biofilm research, most of it with the ultimate aims of biofilm prevention, control, or eradication.The present investigation was aimed to study the cell signaling principle among seaweed epibiotic bacterial organisms , totally 54 bacterial isolates were made out of 20 seaweed species. Among 54 bacterial isolates 17 of them producer, another 17 of them inducer strains rest of 20 isolates were normal that have not showing any signs of activity. The 17 producers and 17 inducer strains were subjected to the cross species induction by quorum sensing principle and found that only 3 of them have responded to the cross species induction in production of antibacterial compound against the respective inducer strains. All the 3 producers and inducer were identified by biochemical analysis and surprisingly that all the 3 producer strain belongs to Genus Pseudomonas and inducer strains were belongs to Genus Vibrio. The supernatant obtain from mixed culture of Pseudomonas & Vibrio shows the antibiotic activity against the various Vibrio species which were isolated from other sources. Such as Vibrio from primary film, Vibrio from sediment Vibrio from seaweeds epibiotics. The obtain results clearly shows the particular Pseudomonas from seaweed epibionts has the capability of producing potential antibiotic compound against wide range of Vibrio species through quorum sensing. Energy Medicine: The Medicine Of The Future—Now Part 3: Living Cells, Energy, And YouBy: Stan | 06/03/2009 | Alternative MedicineEach cell must be able to ingest nutrients, metabolize nutrients, excrete byproducts (toxins), experience growth and mobility, provide protection, and communicate with other cells. The DNA in each cell is needed for the division of cells and for the production of new proteins. It is surrounded by regulatory proteins that need specific vibrational frequencies that unravel the regulatory proteins in order for the DNA to perform its function. The regulation of each cell is triggered either by ce
