Path-breaking discoveries of biology

Biology wonderfully undertakes the natural aspects of life, and stunningly collaborates itself with a human’s infinite curiosity. Over the centuries biology has given us reasons and resolutions to tackle the threatening biological adversities, and it wonderfully continues to do so.

It is impossible to judge which is the greatest contribution in the biology domain, but here are some of the most ultimate biological inventions and discoveries of all time.

The theory of Evolution by natural selection
Darwin’s theory of Evolution advocates the notion that all forms of life has descended from a single ancestor. It focuses on the theory that all the complex forms of organism have naturally evolved from the basic predecessor. Although Darwin wasn’t the first person to study the process of evolution, he was able to gain widespread support because of his coherent demonstrations. The concept of natural selection in evolution basically explains how there is a competition for limited resources in common species. This struggle for surviving is gradually passed on to their descendants, along with certain practical endurance skills. This process of natural selection is also known as survival of the fittest. This theory beautifully projects how and why humans are on the top of the universal food chain.

DNA
DNA, completely turned around the way we look at life. Its discovery was a wake-up call for all the generations. DNA made us understand that the life we are living was never contained, but was rather an unending chain of possibilities. Since, its discovery it has not only affected the medical sciences but has reinvented our approach towards almost all walks of life. Not just in healthcare sector, DNA opened up avenues in agriculture, animal husbandry, forensics and even transformed the social strata of biological relations.

Polio vaccine
Invented by virologist Jonas Sulk, the polio vaccine is of the most crucial inventions of all time. Polio was considered to be the most terrifying health threat post World War 2. Salk undertook a research project affiliated and sponsored by the National Foundation for Infantile Paralysis, after polio claimed thousands of lives and left countless disabled. Not only he developed an effective vaccine consisting of a killed polio virus, but also devised a meticulous plan to combat the outbreak. His trial arrangement had thousands of physicians, health officers and volunteers. Subsequently after the breakthrough of the injected polio vaccine (IPV), Dr. Albert Sabin came up with an alternative oral polio vaccine (OPV) that used the weakened strain of the virus in 1962.

Birth control pills
Gregory Pincus’s birth control pills have revolutionized the biological and social aspects of a human life. After meeting Margaret Sanger, Goodwin was deeply inspired to research on contraception. Along with the co-inventor, Min Chueh Chang, he began developing an oral pill combining estrogen and progestin. Their trials conducted in Puerto Rico were successful, and were later approved legally to be circulated amongst the public. This gradually led to the modern birth control movement advocating planned parenthood, population control and women’s rights.

  • 4 ways plastic bags harm the environment
    Plastic bags are one of the most versatile carry bags. They are also feasible for businesses since they are cheaper than paper and cloth bags. Compared to paper bags, plastic bags are stronger and resistant to water. Hence, many customers prefer to use plastic bags. Apart from using to carry groceries, plastic bags are also re-used by many to line their trash cans. However, once they are disposed of, plastic bags are serious environmental hazards. They do not degrade and accumulate over time and fill up landfills and waterbodies and choke drainage systems. Here are 5 ways in which plastic bags have been found to be harmful to the environment.
    • Issues with landfill Plastic bags are difficult to recycle. Bags made from polyethylene can be recycled into new plastic bags, drainage pipes, composite lumber, or outside the fencing. However, the process of recycling requires that the plastic bag does not have any moisture; in order to be recycled, it is necessary that food or other water-based materials have not been stored in the plastic bags. This reduces the percentage of plastic bags that are recycled. The bags that do not undergo recycling accumulate on the landfills. This increases the volume of the landfill since the plastic bags take a very long time to decompose.
    • Issues with waterways Plastic bags take nearly 400 to 1000 years to decompose. When plastic bags enter the waterbodies, they do not break down completely. They are converted to plastic dust, which is made of compounds knowns as polychlorinated biphenyls (PCBs), which are bio-toxins. These toxins enter the food chain as plants and animals are exposed to the water containing PCBs.
    • Issue with wildlife Plastic bags that are disposed into landfills or released in any way into the environment enter into the water bodies such as rivers, oceans, and tributaries. These floating plastic bags are mistaken for food by the aquatic animals. For instance, sea turtles that feed on jellyfish may mistake plastic bags for food since a floating plastic bag appears like a jellyfish. Once plastic bags enter their bodies, it affects their health since plastic cannot be digested. Small animals and birds get entangled in the floating plastic bags and often strangle to death.
    • Issues with flooding Since plastic bags do not decompose or dissolve in water, they clog drains and sewers. This causes flooding since the normal flow of sewage water is blocked. This issue has been observed in a lot of developing countries.

They can easily fit into 60-inch space which may have been occupied by your previous standard tub. Use space wisely: Extension kits available in the market can resolve any space-related issue. If you have additional space left after the installation of your walk-in tub in place of your conventional tub, you can try matching panels available with extension kits or you could add shelves or drawers in that area.Apart from inward swinging and outward swinging doors, you can consider a sliding panel door which can be raised up to allow the bather to slide into the bathtub seat. This feature is especially useful for individuals using a wheelchair. Mind the details: Most walk-in bathtubs have built-in seats much like a chair. However, the height of the seat can vary in different models. You should check under the product description to get an idea about the height and select one which meets your requirement.

It so happened that while on a trip to Chicago, Dick Cabela bought some fishing flies. When he returned to Nebraska, he intended to sell this product and make a neat profit. His first effort failed after he placed a simple classified advert in a local newspaper. Undaunted by this setback, Dick created another ad that exhorted buyers to benefit from an introductory offer. He placed this ad in some leading outdoor magazines and this time, he was flooded with offers to buy his gear and this is how the journey of Cabela's began. Dick had quickly learnt the ropes of direct mail so every order was mailed out with a mimeographed catalogue of his outdoor products. Mary, Dick's wife, contributed to the venture's success by adding to its product lines. As the sales climbed, Dick and Mary moved out of their kitchen, which was their company's headquarters, to the basement of their family furniture shop. The kept on shifting their offices to various locations and finally settled on a 50, 000 square feet vacant John Deere building in downtown Sydney, Nebraska. Initially, Dick and Mary used to depend upon temporary typists and other workers to fulfill the orders. But with passage of time, the couple realized that it needed more helping hands. In 1963, Dick persuaded his brother Jim, successfully, to join the company. Since then, Dick, Mary and Jim have led their venture successfully through numerous troughs and crests. In the early years, neither Dick nor Jim took any salary from the earnings of the company. Mary did not draw any salary either. These three people re-invested whatever was earned back into the company's business. Today, by lots of hard work and sheer persistence, the company is housed in a 2, 50,000 square feet facility along the Interstate 50 in downtown Sydney. The keystone of Cabela's business is its world-famous catalog business. Its catalogs are focused on archery, fishing, boating, camping and many other outdoor activities.

  • Diabetes: Symptoms and prevention strategies
    Diabetes refers to the condition of your blood carrying an excess of sugar. Sugar is a source of energy, and when it is ingested, the body secretes a hormone called insulin. Insulin helps to "open" cells so that the glucose can enter the cells and energy can be released. Now when there is a shortage of insulin or if insulin is unable to open, the cells for energy is released. The sugar which is ingested is not processed and remains in the bloodstream. This causes diabetes. Although there are different types of diabetes, the symptoms for each of the types are more or less the same. Most of the time, diabetes occurs in people who do not show any of these symptoms at all. Symptoms If you happen to show one or two symptoms from the below list, then it's best you get a blood test done first thing.
    • Excessive thirst on a frequent basis
    • Increased appetite (sensation of hunger even after large meals)
    • Excess urination
    • Fatigue
    • Weight loss
    • Blurred vision
    Small changes to your lifestyle can reduce your risk of getting diabetes by a long way. What Is The Normal Blood Sugar Range? The blood sugar levelis lowest in the morning and the blood sugar level at this time is the Fasting level. The normal blood sugar range for a nondiabetic person at this time is between 3.9 to 5.5 mmoI/L, while thenormal blood sugar range for a diabetic person is between 4.4 to 7.2 mmoI/L. The blood sugar levelrises after a meal, so the test is usually done after 2 hours of consuming food. Thenormal blood sugar range will change in this case. The normal blood sugar range for a nondiabetic person is between 6.5 to 7.8 mmoI/L and the normal blood sugar level for a diabetic person is approximately 10.0 mmoI/L. How to prevent diabetes You can prevent diabetes or at least reduce the risk by taking certain preventive measures. If you are prone to hereditary diabetes, you need to take certain precautions to delay the onset of diabetes. Here are a few preventive measures you can follow. Cut down on the sugar When you consume more sugar, the body has got to produce more and more insulin to burn all that sugar into energy. Now, if you don't give the body so much work by reducing your sugar intake, you are reducing the risk of increased sugar levels in your blood. Work out whenever you can Studies have shown that regular engagement in physical activity improves the sensitivity of your insulin. This means that lesser amounts of insulin are required for your body to maintain the sugar levels. Water all the way Set water as your go-to beverage whenever you are thirsty. Replacing those sodas and carbonated drinks with water will reduce the amount of sugar you consume. If you consume a lot of drinks with high sugar content, you increase your chances of getting LADA (Latent Autoimmune Diabetes of Adults). Treatment for this takes much longer to be effective than the original diabetes itself. Lose weight If you feel that you are overweight or that you have a bit too much on your waistline, create a workout regime and stick to it. Make a plan to change your diet and to hit the gym regularly. When you are overweight, the excess fat around your waist, also called visceral fats, promote insulin resistance which decreases the sensitivity. This increases your risk of getting diabetes. Drop the cigarette Research has shown that smokers have a higher chance of getting diabetes than nonsmokers. If you smoke, even occasionally, try to break that habit. Five or ten years down the road your risk of acquiring diabetes will be the same as that of a nonsmoker. There are several other ways to prevent diabetes. But the most important question is, are you willing to do what it takes to prevent diabetes? Everything worth having comes at a price, so decide to pay that price and reduce your risks of getting diabetes and live a longer and healthier life.
