The article that I have chosen is Early Detection of Parkinson’s disease through handwriting. The topic of this article is disorders and syndromes: Parkinson’s disease. The authors of this article are Sara Rosenblum, Margalit Samuel, Sharon Zlotnik, Llana Erikh, and Llana Schlesinger. The source I used to come to this article is sciencedaily.com.
Dr. Ilana Schlesinger, head of the Center for Movement Disorders and Parkinson's disease at Haifa’s Rambam Medical Center and occupational therapists helped to conduct this experiment. Prof. Sara Rosenblum, of the University of Haifa’s Department of Occupational Therapy, initiated the study. She believed that identifying the changes in handwriting could lead to an early diagnosis of the illness.
During this study, they gathered forty participants, all adults with at least twelve years of schooling. Half of the participants healthy, and the other half known to be in the early stages of Parkinson’s disease (before motor signs are visible). They were instructed to write their names and a given address on a regular piece of paper that was placed on electronic tablet, while using a special pen that had pressure-sensitive sensors operated by the pen when it hits the writing surface. The number of parameters: writing form, time required, and the pressured exerted were compared using a computerized analysis. Once the results were in, it showed a great difference between the healthy and the patients. All subjects, except for one had their status correctly diagnosed. The patients with Parkinson’s disease wrote with less pressure on the surface and with smaller letters, taking longer to complete the task. Professor Rosenblum, a noticeable difference was the length of time the pen was in the air between writing each letter and word.
This article proves an effective way to notice if you have Parkinson’s disease at an early stage…...

...The importance of science education for children Published 03/11/2008 Science Communication 17 Comments  Tags: Science Education One of the features of wordpress is a list of what web searches have led people to your blog (or at least hits anyway) and they themselves can be fascinating glimpses into what people are interested in or what information on (mostly Tyrannosaurus and Jurassic Park). A recent one was the title of this post and it is a very interesting question (precisely it was “what is the importance of teaching science to children?”). Apart from the fundamental answer (well, everyone should know a bit about biology, chemistry and physics, much as they should know a bit about history, geography, art and maths) it is a good question. What does science bring to the table? It’s hard to put in specific terms, but science as a concept (as opposed to just learning facts and theories, or heating stuff in test tubes) has some nice ideas to offer that would be useful for many people to learn and would be useful throughout their lives. Concepts such as logical deductions and inference, parsimony, and not accepting arguments (or dismissals) based on authority but from evidence, and scepticism would all be handy. Teaching someone how to appraise and evaluate conflicting evidence and any bias in that evidence would be useful ‘life skills’ for pretty much everyone. Let’s face it, it ultimately comes down to trying to spot patterns, work out reasons for them, and to spot......

...Science On the question of science, participants on various occasions referred to some of the misunderstandings surrounding this concept. It was repeatedly mentioned that, notwithstanding general agreement among development planners and practitioners about the crucial role that science has to play in development, many lacked a common understanding of its nature or the ways in which it can contribute to the wellbeing of the masses of humanity. As the discourse evolved over several years, many of these misconceptions were brought to light. Some of them are as follows: First, the practice of science is all too often reduced to the mere application of technology. What is lost sight of is the fact that science is a system of knowledge and practice that provides the methods and tools for the systematic and structured exploration of material and social reality. By asking questions about reality and seeking to answer them through a process of action, reflection and consultation, a population acquires the capacity to take charge of its own development and to promote the advancement of civilization. Due to the existing misrepresentation of the role of science in development, attention is focused on making people passive consumers of technology rather than on building their scientific capacity. Development Development as a concept is a victim of definitional pluralism. It is a difficult word to define. However, attempts have been made by erudite scholars to conceptualize......

...present era is the era of science. Science has undoubtedly done a great service to mankind. Man, a rational being, has been curious to explore mysteries of nature and this led to many discoveries being made in various part of the world. But he is never satisfied with the acquired knowledge and is always keen to unravelle mysteries of the universe. He has conquered the land and air. His incredible lust for knowledge has revolutionised human life and raised the standard of life. He was able to invent innumerable ways of making his life comfortable and happy. Every sphere of life has been revolutionised by science. There have been innumerable inventions. One of the greatest inventions is the invention of medicines. There has been a series of tests carried out using animals as subjects and various medicines have been tried out on these animals to check their efficacy. Many fatal diseases can now be cured because we have the drug to fight those diseases. It has reduced the rate of infant mortality and increased the life span. Before these inventions millions of people died for lack of medical care. Science has given us many machines that have made our lives very comfortable. Buses, cars, sewing machines, mixes, grinders, etc. are all machines that are used every day by us and the discovery of electricity has made it possible for us to change night into day and summer into a comfortable cool season It is now easy to cultivate fields as we have tractors. New forms of......

...Science to me is everything that surrounds us. It's to discover information about this world we live in, study this information, and use it however we will; a process that has started long, long ago, and will continue in generations to come. Everything in our world that we use somehow or someway was made by science. It started with discovering something new; then study what it can be capable of. See where this new founded information can be fit into use. Science was used to create something new. In this day and age science has taken us to an entirely new place. From better batteries, to faster computers, to better gas mileage, there has just been a huge breakthrough in science. It is both chemistry and physics. In science of chemistry there is discovering elements and using these elements in chemical bonding. For physics, there are already discovered laws, and properties; such discoveries as gravity, motion, force, speed, velocity, acceleration, etc. Science even branches off as far as the universe and its discoveries. Whether the discovery is 200 years old, 100 years old or present, it's science nonetheless. Science is all around us, from the laptops we use to the cars we drive, something had to be discovered and study for us to able to use either. Maybe it was chemical combustion to get the energy from oil so our cars can move, or even some physics to help us understand how much energy we can save if we make something for aerodynamic. Science is to discover information......

...monitoring platform Project NOAH under the Department of Science and Technology, said that YouTube user DutchSince who created and lent his voice on the video may not himself believe his claims. "From the images he was showing, it would appear that the typhoon was already developed when he was showing the microwave pulses that were being transmitted. And the second thing that I noticed was that he was also relating the microwave pulses with the occurrence of earthquakes, and what we know about earthquakes is that they form because of the accumulation of energy due to earth movements. And through time, this energy is accumulated along faults and it does not at all relate to any type of microwave he was referring to," he said. "He is just pulling a trick on us ... As of the moment, there's no reason to believe this person," Lagmay added. The video uploaded last November 8 gained attention on YouTube amid overwhelming news on the catastrophe wrought by the powerful cyclone. Dutchsince, voicing over moving satellite images of the typhoon's movement, said that a US facility based in Alaska manipulated the direction and strength of the weather disturbance. "We can follow this storm's formation ... and what we've seen several times is out here near Guam, of all places, we see a large microwave-shaped spiral pulse that comes from the north," the narrator said. The conspiracy theorist also claimed that microwave pulse is now controlling a new weather system named "Zoraida"......

Heather Dewar wrote the original article of this edition. According to the article Biogeochemical gestures, in Brazilian 2.5-billion-year-old carbonate rocks disclose that sulfur-consuming bacteria were full of life at a time when levels of ocean sulfur were low. Geologists concentrated on sulfur isotopes in antique carbonate rocks. The research study reveals early atmospheric chemistry of the Earth (University of Maryland 2014, November 6). There is a heated debate around the evolution of sulfur-dependent bacteria among the numerous scientists who study the early history of planet earth. The scientists claim that these organisms lived when there were fewer oxygen levels in the atmosphere (less than one-thousandth of their quantity now). Active in ocean waters, the bacteria breathed in sulfate instead of free oxygen molecules. The big question is how the sulfate reached the ocean and how it...

...The word 'science' is derived from the Latin word 'scientia' which means knowledge. Therefore, science is about gaining knowledge either through observing, studying, experience, or practice. Entire knowledge acquired through science is about discovering truths, finding facts, uncovering phenomenon hidden by the nature. Observations and experimentation, in science, support in describing truth and realities through systematic processes and procedures. For me, science is an intellectual set of activities designed to uncover information about anything related to this world in which we live. The information gathered is organized through scientific methods to form eloquent patterns. In my opinion the primary objective of science is to gather information and to distinguish the order found between facts. What Science Means to Me as an Upcoming Scientist Science exposes several ideas along with significant themes so that I could test them independently and without any bias to arrive at solid conclusion. For this purpose exchange of data and materials is necessary. I am able to generate real and tangible facts supported by reliable evidence. Work of scientist is based on theoretical science. It means, in theoretical science, there is only a sign, just a hint on which discoveries could be made, facts could be found. While studying science I am always working for determining truth, based on my perceptions, judgment, observation, experience, and knowledge collected through several means...

...Science (from Latin: scientia meaning "knowledge") is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the world.[1][2][3][4] An older and closely related meaning still in use today is that of Aristotle, for whom scientific knowledge was a body of reliable knowledge that can be logically and rationally explained (see "History and etymology" section below).[5] Since classical antiquity science as a type of knowledge was closely linked to philosophy. In the early modern era the two words, "science" and "philosophy", were sometimes used interchangeably in the English language. By the 17th century, "natural philosophy" (which is today called "natural science") had begun to be considered separately from "philosophy" in general.[6][7] However, "science" continued to be used in a broad sense denoting reliable knowledge about a topic, in the same way it is still used in modern terms such as library science or political science. In modern use, science is "often treated as synonymous with ‘natural and physical science’, and thus restricted to those branches of study that relate to the phenomena of the material universe and their laws, sometimes with implied exclusion of pure mathematics. This is now the dominant sense in ordinary use."[8] This narrower sense of "science" developed as a part of science became a distinct enterprise of defining "laws of nature", based on early examples such as Kepler's laws,......

...Chapter 132 - Science and Technology Section SCIENCE AND TECHNOLOGY Science and technology provide people with the knowledge and tools to understand and address many of the challenges. Students must be provided with opportunities to access, understand, and evaluate current information and tools related to science and technology if they are to be ready to live in a 21st century global society. The study of science and technology includes both processes and bodies of knowledge. Scientific processes are the ways scientists investigate and communicate about the natural world. The scientific body of knowledge includes concepts, principles, facts, laws, and theories about the way the world around us works. Technology includes the technological design process and the body of knowledge related to the study of tools and the effect of technology on society. Science and technology merge in the pursuit of knowledge and solutions to problems that require the application of scientific understanding and product design. Solving technological problems demands scientific knowledge while modern technologies make it possible to discover new scientific knowledge. In a world shaped by science and technology, it is important for students to learn how science and technology connect with the demands of society and the knowledge of all content areas. It is equally important that students are provided with learning experiences that integrate tools, knowledge, and processes of science and......

...Science is the concerted human effort to understand, or to understand better, the history of the natural world and how the natural world works, with observable physical evidence as the basis of that understanding1. It is done through observation of natural phenomena, and/or through experimentation that tries to simulate natural processes under controlled conditions. (There are, of course, more definitions of science.) Consider some examples. An ecologist observing the territorial behaviors of bluebirds and a geologist examining the distribution of fossils in an outcrop are both scientists making observations in order to find patterns in natural phenomena. They just do it outdoors and thus entertain the general public with their behavior. An astrophysicist photographing distant galaxies and a climatologist sifting data from weather balloons similarly are also scientists making observations, but in more discrete settings. The examples above are observational science, but there is also experimental science. A chemist observing the rates of one chemical reaction at a variety of temperatures and a nuclear physicist recording the results of bombardment of a particular kind of matter with neutrons are both scientists performing experiments to see what consistent patterns emerge. A biologist observing the reaction of a particular tissue to various stimulants is likewise experimenting to find patterns of behavior. These folks usually do their work in labs and wear......

...Lydia Hernandez Bio 156 Module 5 Cellular Respiration Cellular Respiration is the process by which cells acquire energy by breaking down nutrient molecules produced by photo synthesizers. (Mc-Graw-Hill, 2014). Oxygen and carbon dioxide are what makes cellular respiration, without it, no animal, human or plants would breathe. Cellular respiration has four phases and that includes: glycolysis, citric acid cycle, preparatory reaction, and electron transport chain. The first phase is glycolysis and it takes place outside of the mitochondria and during this phase it does require oxygen. During this phase, glucose is broke down to two molecules of pyruvate. During the breakdown it release enough energy to give a net gain of 2 Atp. Preparatory reaction and citric acid cycle follow next and occur in the mitochondria. The preparatory reaction happens in the matrix of the mitochondria. Carbon Dioxide is release and pyruvate is broken into a 2-carbon acetyl group. The citric acid cycle also takes place in the matrix. Oxidation occurs when two carbon dioxide molecules, three NADH molecules, and one FADH2 molecules are formed. This phase produces one ATP. The final phase is the electron transport chain that is located in the cristae in the mitochondria. FADH2 and NADH bring electrons to the transport chain. The electrons move down and energy is caught to form ATP. For every pair of electrons that enters by NADH, three ATP result and 2 ATP result by Fadh2. (Mc-Graw-Hill,......

...The importance of science and the ways of expressing scientific ways of life to the world. The start of scientific rules and the ways to explain the methods it follows .Science is based on methods that explain the way science goes on around the world and what is the importance of it that helps people understand things beyond imagination (Thomas Samuel Kuhn). The scientific ways of expressing the world and how it generates based on its history. The importance of science, the scientific methods, and the scientific expression of how the world generates based on its history are the three major descriptions of science. One of the important facts about science is the start of scientific rules and the way to explain the methods it follows (See Appendix 1). Science is based on the knowledge that humans have to know the mystery behind things that cover the truth behind something. Science has many rules that have been passed on by one of the greatest scientists that discovered the ways of life and things that were not predictable. The scientific method is a procedure of six steps they are stating the problem, collecting information, forming a hypothesis, performing experiments, analyzing the data (Alhazen), and making a conclusion. The first step to the scientific method is to stat the problem in which you wish to Answer. The second step is collecting information on the question answered. Making observations and study the things on the question you have more knowledge on the......

...Blessing of Science Blessings of science are numerous. Science has completely changed the living style of man. Now man is living in a totally 18 century. From home to office, from farm to factory, form village to town, in short everywhere in life now we can see the unlimited blessing of science. At home, we find that science has provided many comforts to the human beings. Whether it is kitchen, lounge, shaker, chopper, toaster and many other appliance have brought a revolution in the working of a kitchen and a housewife. Although it is a fact that science can not fight with fate and it often fails to defeat nature yet it has done a lot to minimize the disastrous effects of nature. Scientists have invented such machines like air conditioner and heater that can give comfort to the man in hot summers and in extreme winters respectively. Now there are such instruments, which can warn man against floods, earthquakes and windstorm. After getting such warnings human beings are able to take preventive measures. Travelling and transportation were very difficult and paining in the past but now the miracles of science have made the travelling a luxury. Now there are variety of means of transportation like buses, cars, trains and aero-planes that have decreased the distances and have made the journey a comfort. Now hundreds of people can travel from own country to the other country in one train or in one aero-plane. The distance that could be covered by the people in the months...
