The lab microscope is essential to every scientist, and is used everywhere today from medical labs to schools. Microscopes have been in use since the mid seventeenth century, and were used by Anton Van Leeuwenhoek in his observations of some of the first microorganisms. Those early microscopes had only a single lens and were extremely simple, allowing only the briefest glimpse into the fascinating world of the microcosm. Today lab microscopes can range from a simple compound microscope with two lenses, to more complex, digital microscopes that come with cameras, motion recorders and laser scanners. Many labs have multiple microscopes, each used for a set purpose, as some work better than others in...

Many people think that a lab refrigerator is just a larger version of the domestic refrigerator. But there is more to a lab freezer than what a novice knows. Lab refrigerators are specifically designed to store critical materials over extended periods of time. The temperatures of these refrigerators is maintained and kept constant at all times so that the many specimens and samples that are kept in it can be preserved in a stable environment. There are mainly two types of lab refrigerators. One is called the chest freezer and the other called the upright freezer. The main difference between the two is the footprint space that they take. The upright refrigerator, in comparison to the chest...

The position of clinical laboratory technician is crucial and is important in the detection, diagnosing and treatment of diseases. Laboratory tests are performed by technicians and the test results identify the accurate disease or illness that a patient have. The clinical laboratory technicians carry out less complicated tests and laboratory procedures. Usually, they prepare or collect specimens, operate automated analyzers and performed manual tests as per a detailed instruction. They perform chemical analysis of body fluids, such as blood and urine, to detect abnormalities or diseases and encoding findings into a computer. Technicians conduct blood tests and perform blood counts for transfusion...

Stanley Miller, a graduate student at the University of Chicago in 1953, experimented with the creation of life in his laboratory by simulating Earth's atmosphere of 3.8 billion years ago (ammonia, methane, hydrogen and water vapor), using electric sparks to simulate lightning. The experiment produced a reddish "slime", only a simple inorganic compound, with no life or subsequent development, but Miller's experiment was widely reported - and erroneously interpreted - as proof that life could have started similarly - naturally and by chance. While a synthetization by non-biological reactions of amino acids, building blocks of protein as found throughout the universe, they were "far from being alive...

Introduction Think of your old manual Spectronic 20, or your direct reading spectrophotometer that you use in your lab. You line up your samples in a row. In front of them, you place some small sample cups or maybe even a series of cuvettes, and you pipette a known amount of sample into each cup. You then add a reagent and somehow mix the reagent and sample. You do this for each sample. You may have more reagents to add so you repeat the whole process until all reagents are added. Then you start a timer. When the timer beeps you know you have a certain "time window" to read the absorbance (or concentration) of your samples. You read by manually transferring the color-developed sample to a...

In every laboratory around the world, there is a dire need for refrigeration. Nearly every reagent needed in chemistry analysis requires refrigeration, and some must be kept at a precise temperature to remain stable. Laboratory refrigerators are needed for this purpose, as a regular household refrigerator may not have the stable temperatures needed by the products used by the laboratory. Most laboratory products needing refrigeration are very sensitive to certain low or high temperatures. Some of these materials can only be safely stored at a very close and precise range of temperatures, so keeping them safely stored around the clock is vital for the cost-effectiveness of the laboratory. Having a...

An analytical balance is used to measure mass to a very high degree of precision and accuracy, because unlike spring scales their accuracy is not affected by differences in the local gravity. A change in the strength of the gravitational field caused by moving the balance will not change the measured mass, because the moments of force on either side of the balance beam are affected equally by the pull of gravity. The weighing pans of a high precision (.01 mg or better) balance are inside a transparent enclosure with doors so that dust does not collect and so any air currents in the room do not affect the balance's operation. The use of a vented safety enclosure with an analytical balance which has...

Although it has been a subject that science has ridiculed for decades, subliminal messages have new scientific believers. A recent laboratory study into subliminal messages has revealed some startling evidence that are indeed recorded by the brain! A neuroscientist at the Institute of Cognitive Neuroscience University College London, called Bahador Bahrami, has found through laboratory experiments that subliminal messages do indeed leave an impression on the brain. Using sophisticated equipment Bahrami's team of scientists discovered that the brain is aware of, and records, images that we are consciously not aware are there. Bahrami had a group of volunteers view a computer screen while wearing 3-D...

The incubation period is about 10 days to onset of fever and 14 days to appearance of rash. The prodromal period is characterized by fever, sneezing, coughing, running nose, redness or eyes. Koplik's spots (enanthems of the buccal mucosa), and lymphopenia. The fever and cough persist until the rash appears and then subside within 1-2 days. The rash spreads over the entire body within 2-4 days, becoming brownish in 5-10 days. Symptoms of the disease are most marked when the rash is at its peak but subside rapidly thereafter. In measles, the respiratory tract becomes more susceptible to invasion by bacteria, especially hemolytic streptococci; bronchitis, pneumonia, and otitis may follow in 15% of...

Vampire folklore is prevalent throughout European history. Some tales date back as far as the 12th century. It's possible that these early tales of vampires were spawned by real medical conditions. Porphyria There are several types of porphyria. Four of the types have symptoms of light sensitivity: Variegate Porphyria, Porphyria Cutanea Tarda (PCT), Erythropoietic Protoporphyria (EPP) or Protoporphyria, and Congenital Erythropoetic Porphyria (C.E.P.). Other symptoms include brown teeth, red and sometimes bloody gums, and hypertrichosis (excessive hair growth). These symptoms mirror many vampire legends. However, victims of porphyria do not crave or drink blood. Catalepsy Catalepsy is a neurological...

Nature has given us the wealth of herbs. Knowingly or unknowingly, its values have been discovered. Since the time when the practical and theory of medicines came into execution herbs have played a significant role. Millions of herbs have been explored since then and were adopted by modern medical practitioner.

Prof Hawley added however that global food scarcity and climate change were also factors that could trigger global chaos, saying the Government had to make difficult resource decisions and continually re-prioritise in a changing, unstable, global environment. Prof Hawley now works at the University of Glamorgan as a Professor of Disaster Studies. He said the threat that avian flu could cross over into humans was one that was absolutely still on the radar, adding that he was glad he was not a politician having to make such hard decisions on the resources around disaster management. Veterinary laboratories are crucial in monitoring the development of infections in animals that could pose a threat to...

I have read articles explaining behaviour and appearance as products of genetics. The study of genes and how they control the aforementioned attributes and others like the predisposition to certain diseases, for example, is fascinating. In fact, genes hold characteristics which are hardwired into the ooze and the essence of who we are. I started thinking about the genetics of retail. If one wants to know about their personal genetics they observe their parents and and their parents parents and...well you get a feel for how far that could go. But if you want to know about your retail genetics look at those who taught and mentored you. I suggest to you that many of the systems, policies and...

In fact, of the top 10 causes of death in America, men are only affected less by one, Alzheimer's disease. Men also have more chronic illnesses than women. They are nearly 10 times more likely to get inguinal hernias than women, and five times more likely to have aortic aneurysms. Four times more American men get gout, and 3 times more become alcoholics, get bladder cancer, or kidney stones. Two times more men suffer from emphysema or duodenal ulcers. So why do males die more frequently? Genetics? Men have only a single X chromosome and Y chromosome (which has few genes). Women, with two X chromosomes can sometimes get away with disease causing errors in the X chromosome by having a good backup copy...

More hair growth is waiting around the corner for you thanks to the help of natural remedies and baldness cures.

Both men and women can benefit from the use of natural hair loss remedies. Many of them are easy to make and can be used whenever you feel the need. One thing to keep in mind in order to beat genetics and get your hair back is to increase blood circulation. A lot of times people misunderstand exactly why their hair is falling out. Some blame their genetic makeup, when really the problem lies in how much blood is flowing to their follicle roots...

The age old question regarding baldness has always been where does it come from? How does it happen? Is it hereditary? If my daddy was bald, does that mean I will also become bald? Throughout recent years there have been numerous studies relating to hair loss in general terms. Many scientists in these studies have studied the chromosomes and genetic makeup of both balding men and their 'fully-haired' counterparts. While there are no concrete conclusions available, the results gathered so far indicate that male pattern baldness is in fact a hereditary phenomenon. From these studies conducted to date, it has been a common finding that this form of baldness originates in the genes coming from our...

No matter who you are, I believe that you can build thickly muscled and chiseled biceps regardless of your size or body weight. Having said this, the fact remains that not all of us have the genetic potential to become Mr. Olympia (and most of us probably don’t want that much development anyway). The exact role of genetics in bodybuilding is not fully understood. One thing is certain – you’ve got to train smart to maximize whatever genetic potential you have to build massive, well-defined biceps. Some people use “bad genetics” as a convenient excuse for quitting their training programs when they fail to see quick results. Don’t fall into this trap. You must remember to set your own...

There are some men out there in the bodybuilding world who can just naturally see a good weight gain. They simply look at a dumbbell and it seems like they build muscle overnight. Then there are those in the bodybuilding world who don't. These are often know as the 'skinny guys' or 'hardgainers'. These are the individuals who train and train and train, and yet still cannot seem to build muscle if their life depended on it. What's the story with them? Are they destined to live the life of a string bean forever? Or can something be done with them too, to get their body looking more strong and shapely? You bet there is. These individuals just need to learn the 'hardgainer' secrets that should be...

Genetics is a notorious course for demanding a high-volume of information in a short amount of time. However, there are studying methods to assist students in learning efficiently and effectively. I have studied and interviewed groups of medical and science students that have mastered their course work. It is true that there are specific and detailed guidelines that these students adhere to and credit for their academic success. The successful student must understand the fundamental science of DNA and expand on it as a discipline of inheritance and variation in organisms. With some time and applying these study strategies and tips from past honor students of Genetics, you will greatly improve your...

If you want to gain muscle and get big then there's no need to blame your genetics. I've met so many skinny guys who told me that they've tried everything to build muscle, but nothing had worked. The reality is that they weren't trying hard enough. If you want to transform your physique, if you want to add a lot of rock solid muscle to your frame then you'll need to follow a proven action plan and most importantly you'll need to work hard. Increase Your Daily Caloric Intake In order to make your body grow you first of all need to give it more energy which comes in a form of calories to make it grow. This is why you've got to increase your daily caloric intake. Everything starts here. Follow a High...

The answer to the obesity epidemic sweeping the world seems to be divided. Depending on the point of reference, some are adamant the gene pool plays a major role but others put forward a strong argument to say that diet, lack of exercise and the modern lifestyle are a greater problem than the gene pool. Whatever your personal feelings are on the subject, the one thing that everyone must agree on is that this subject needs to be talked about much more than it already is. This snowballing epidemic has already affected more than 31% of all Americans, 25% of Mexicans, 23% of those living in the United Kingdom and the list goes on and on, people where ever you are, this is not a contest you want to win...

When scientists started studying the genetics of breast cancer, they hoped to understand the mechanism by which the disease developed and so reveal new ways of treating it. They did not expect to end up furthering the commercial interests of insurance companies. Yet insurers in Britain have been taking account of the results of genetic tests for breast cancer in granting insurance cover, even though two separate Government Commissions have recommended a moratorium on the use of such information. Only after a public outcry has the Association of British Insurers accepted a voluntary, two-year ban on the use of genetic test results for policies over £300,000. Insurers have a legitimate fear of...

You can prevent tinnitus by taking steps and precautions especially if you have bad genetics. It is much easier to prevent tinnitus than it is to cure it. The first step in preventing tinnitus is too avoid exposure to loud noises along with avoiding head and neck trauma. If you know you are going to be exposed to loud noises or high frequencies you should take precautions to protect your hearing. If you already have tinnitus you should take precautions to protect your hearing because it is possible that your tinnitus can get worse. Proper precautions include wearing protective earplugs and earmuffs. It is best to avoid places you know are likely to have loud noises such as concerts and clubs. In the...

Allergy is the body's hypersensitive reaction to any external allergen and its symptoms may vary in intensity among various individuals. While some people might not even notice these symptoms; for others, the reactions of the immune system are so severe that it may even threaten their life or give rise to many complications. What causes this difference in allergy symptoms intensity is genetics. This means that the individual is more susceptible to a hyperactive reaction or response to allergens. Allergens are mostly harmless substances that may be safe for others but quite detrimental to the person who is allergic. If your parents suffered from some allergies then it is quite likely that the...

If you have been dealing with going bald for some time now, then you might be interested in male pattern baldness genetics. The genetics behind male pattern baldness can reveal not only why we suffer from it, but also what options we have to treat it. The idea behind it is very simple and I really think it will help you deal with your problem. I am going to tell you all about male pattern baldness genetics and how they are affecting you. The main cause of male pattern baldness is a serious lack of DHT. No other reason for hair loss is so common. It is a genetic disorder that most men, about 57%, have the baldness gene. This is no reason to fear however. You see, since we know the most common cause...

Autism is a very complex neurodevelopmental disorder and due to this face there are many proposed theories on the causes of autism. Even though these theories can explain some cases, it's hard come up with an exact case for this disorder. What makes autism a very special case is that there are more theories that come from a controversial angle, such as vaccinations, even though there isn't any convincing scientific evidence to back this up. Genetics Genetics is considered one of the most likely reasons autism occurs. It is estimated that 90% of autism is a result of genetics. As you know, genetics is a very complex science that is relatively new in our age of science. It isn't believed that the...
