    Everyone has heard of the classic volcano science project using vinegar, baking soda, and a little bit of red food coloring. This little experiment, however, is a little more extreme, and a little more realistic (do not worry, it is not actually dangerous!). This guide will teach you how to create a volcano project that really erupts with some force.
    Unfortunately, the fake lava is not going to be quite so realistically red, but sometimes compromise means sacrifices! Here we go:
    Gather your building supplies. For this project, you are going to need to start with a volcano. A prepackaged paper mache kit is recommended. Next, you need a two-liter bottle of diet cola. Use your paper mache kit to build a mountainous, volcanic structure around the bottle, leaving a hole at the top large enough to facilitate opening the soda bottle. Give your paper mache plenty of time to dry before you attempt the next step, or else you will end up with a sticky mess on your hands.
    Paint your volcano. This is where you can get pretty creative, even though most volcanic mountains look pretty much the same. You can go for the standard black and brown color of rocks and dirt, or you can get a little artsy. Why not make a tie-dye themed volcano? It is just a science experiment, and science should be fun! After applying your paint, make sure that it is completely dry before you begin the next stage: Explosion!
    Now it is time to add the trigger to the equation. Go to your local convenience store and buy a roll of mint Mentos. It is very important that you buy these in particular, as nothing else will work correctly.
    Ready your presentation in a clear, outdoor space (trust me; you do not want this volcano erupting indoors!). Carefully take the cap off your diet cola, which, if you have followed directions, should be housed securely in your paper mache volcano. Commence with a dramatic countdown, and at its conclusion, drop a couple of the Mentos into the cola.
    ERUPTION!
    This is a fun experiment to do at school or at home, but if you are planning to attempt it, there are a few safety precautions to take. The reaction of the cola to the mints is very strong, and you definitely do not want to put your face near the opening of the soda bottle for the initial eruption. It is recommended that you wear goggles or some type of protective eyewear if you are going to be the one tossing the mints in the soda. Other than that, enjoy the spectacle!

    Elizabeth Whelan, President of the American Council on Science and Health (ACSH) posted a great entry on ACSHs Health Facts and Fears blog on the growing attempts by activist groups to convince the EPA to ban atrazine due to cancer claims and other health concerns.

    Atrazine is one of the most widely used herbicides in the world. It helps farmers fight weeds on corn, sugar cane and other crops, leading to dramatic increases in crop yields. Without it, our food supply would be in jeopardy. Activists want the public to believe that atrazine causes cancer and birth defects, but its simply not true. Whelan writes:

    “Atrazines health and safety record is stellar. The Safe Drinking Water Act requires monitoring for a multitude of chemicals, including atrazine. Levels of atrazine in U.S. waters are well within the federal lifetime drinking water standard a level containing a 1,000-fold safety buffer. The Environmental Protection Agency in 2006 completed a 12-year review involving 60,000 different studies and concluded that the current use of atrazine poses “no harm” to the general population infants, children and adults. According to this same regulatory agency (which oversees pesticide use) atrazine is “one of the most closely examined pesticides in the marketplace.”

    Circulating Tumor Cells can be found in the blood of patients with primary tumor. These cells are extraordinarily rare and their detection presents a major challenge. But collaboration between bioengineers, molecular biologists and clinicians, many technologies have been developed which can detect CTCs. There are many ongoing research on this which are facilitated by the reports generated earlier. Because of the circulating tumor cells clinical significance, there has been a lot of stress on developing methods that can allow detailed studies across multiple types of cancer and its detection.

    Detailed study on CTC technologies shows that this field of biotechnology can offer unique opportunities for the detection of tumor cells in patients with early stage cancer. It also confirms the ability to genetically characterize tumor cells without needing an invasive biopsy, and determine responsiveness to the new generation targeted cancer drugs. Some of the latest reports even discuss the ability of CTC technology to offer the opportunity to study -cancer stem cells- or -metastasis precursors- which were thought to be at the origin of cancer spread via the bloodstream, to define their molecular vulnerabilities and help design new therapies to prevent cancer metastasis.

    Clinical research on circulating tumor cells technologies can be considered to be in its early stages and it has a long way to go. This field of research work is getting mass support from private and government organizations and reaching new heights every day. Its remarkable significance in pharmaceutical industry is encouraging many investors and business person to invest in its R&D for discovery of some technologies that really bring some highly effective difference in the process of cancer detection. Hope of a number of cancer institutions and future of cancer patients depend on the development of CTC technologies. The next generation of clinical trials is waiting to be designed based on the upcoming reports.

    Many things we encounter in our daily lives have been created with the help of an electro mechanical engineering technician who works in automation and robotics. Automation is the use of machines, control systems and information technologies to optimize productivity in the production of goods. Meanwhile, robotics deals with the design, construction, operation, and application of robots as well as computer systems for their control, sensory feedback, and information processing. Combined, automation and robotics creates automated systems that are at the heart of virtually all advanced manufacturing industries. As such, electro mechanical engineering technicians may work in maintenance, in which professionals fix assembly lines or technical sales and service, in which professionals sell them. In addition electro-mechanical engineers can design, program and install robotic systems and the associated interfacing with other factory control systems including programmable logic controllers, human-machine interfaces and supervisory control and data acquisition software.

    To enter this technological field, students must complete a post-secondary program such as Centennial College’s Electro-Mechanical Engineering Technician – Automation and Robotics. In this offering, students obtain theory and practical laboratory experience through which they learn basic technology used in building and operating automated industrial systems: Programmable Logic Controllers (PLCs), hydraulics, pneumatics, electronics and robotics. More specifically, Electro Mechanical Engineering Technician students attend various courses such as: Digital Electronics (students are introduced to digital circuits in this lab and theory course. They study Boolean algebra, mapping and all common gates, gated latches, flip-flops, counters, and shift registers); Robotic Devices (topics include programming the ABB robots, challenges of the integrated systems, robot safety guidelines, terminology and classification of robots, definition of robotics in CIM systems, and end of arm tooling); Report Writing in Technical Environment (students present technical information in appropriate formats that meet professional/workplace standards. Students write a formal report, a number of informal reports, technical descriptions, and records of data/research); and more.

    This automation robotics engineering offering allows students to either graduate as technicians after two years, or continue for additional study and co-op work experience in Centennial’s three-year Automation and Robotics Technology program. The main difference between the two is that the latter offers a co-op experience, which involves students partaking in a field placement during which they apply what they have learned during their courses and have a chance to network with seasoned professionals.

    Thanks to a growing body of research, scientists are now recognizing that having more stem cells in ones bloodstream could be one of the greatest strategies for optimal health. For example, a number of recent studies have shown that a greater number of circulating stem cells equated to greater cardiovascular health.

    Lets look at some of these studies in a little more detail so you can grasp the potential benefits of supporting your bodys natural release of stem cells into the bloodstream

    In 2001, Vasa et al reported that compared to healthy individuals, people with cardiovascular problems had fewer endothelial progenitor cells (EPCs) in their bloodstream. EPCs are a type of stem cells responsible for the development of new blood vessels. The study also demonstrated that the EPCs isolated from people with cardiovascular problems showed less ability to migrate in tissues. The Vasa group also reported that smokers had fewer EPCs in their blood.

    The pick and place robots are very useful things to work with. These are the ones which are known to make the job easier and faster. The main work of the pick and place robots is that these pick up the things from one place and then drop it in some other place. This makes the work organized and it reduces the labor cost as well. The pick and place robots have replaced many laborers as they do the work efficiently. The companies which have high production rates generally go for the pick and place robots. These are known to make the job of the people very easy and the efficiency rate also increases such that the production rate eventually grows high. Hence the people now have switched to the pick and place robots from the laborers. This is also the reason because these robots have many great advantages linked to it. The main aim of the servo motor amplifier is that these take hints from the input signals and then amplify the output signals such that the signal can now be used for some other experimental purposes. This makes the job of the servo motor amplifier all the more essential. These are important because not always is the input signal sufficient for the experiments. One also needs to amplify them for proper results and also for the experimentation purposes. The amplifier has a sensor attached to it. The function of the sensor is to monitor the correct value of the amplification and then it sends back signals to the input ensuring that the work is done properly. An acknowledgement is a must in such cases. This makes the person be assured that the amplification is right and the experiment is going on in the right track. The servo motor circuit is so beautifully designed that it does most of the work of the machines. These handle with a lot of responsibilities and do the work well also. The sensor can be mounted in the motor and the readings can be taken accurately. This is not possible if the motor does not have one. This also is important because this is the one thing which keeps a track of all the happenings of the motor and also the signals and their amplification. So the people now have got used to the very same concept of the servo motor circuits and also the amplification.
