Media Is Boon or Bane

Bacteria are some of the most diverse organisms in nature. These single-celled organisms cannot be seen with the naked eye and are found in many different habitats, like soil, air, water, hot springs and acidic environments. Bacteria are identified using a method called Gram staining, whereby a stain is used to differentiate different types of organisms. Bacteria with and without a cell wall are classified as Gram-positive or Gram-negative, respectively. Bacterial types vary by shape and size.Coccus Coccus refers to spherical shaped bacteria that may live as individual cells, or pair up to form chains or bunches. Staphylococcus and Streptococcus are the most common bacteria in this group and usually are Gram-positive. These bacteria perform useful functions in the body and environment but they can be harmful. Staphylococcus aureus can cause impetigo (skin infection), scalded skin syndrome and food poisoning, while Streptococcus pyogenes may cause tonsillitis and strep throat. BacillusBacillus refers to rod shaped bacteria that are usually Gram-positive or negative. E. coli and Salmonella are the most commonly encountered species responsible for food poisoning and typhoid fever, respectively. According to the University at Albany, bacillus also includes two of the most dangerous bacteria known, that is Bacillus anthracis, which causes the lung disease anthrax, and Clostridium, which causes botulism, gangrene and tetanus. Rickettsia Rickettsia is a very unique type of bacteria because it behaves like a virus and cannot survive outside living cells.The organism is Gram-negative, coccus or sphere-shaped, and is spread through the bite of infected fleas, ticks and lice, which are known as vectors, or carriers. Rickettsia is responsible for typhus, Rocky Mountain Spotted fever and Rickettsialpox, a body rash. Mycoplasma Mycoplasma does not have a cell wall and may be rod or sphere-shaped. This gives the organism a unique advantage because it is unaffected by antibiotics, which work by damaging the cell wall. Mycoplasma pneumoniae is responsible for respiratory disease, while Mycoplasma genitalium causes pelvic disease.Spirillum Spirillum refers to corkscrew or spiral-shaped bacteria that are Gram-negative. Treponema commonly is responsible for the sexually-transmitted disease syphilis. Borrelia has been known to cause Lyme disease, which is transmitted by a tick bite. Although there are five different types of bacteria, there is a lot of variation among each species. The organisms have evolved to such an extent that they are able to thrive in the harshest of environments with amazing adaptation abilities. N. R.

Dating back to the early years of mankind, humans used fire to keep warm. Even today people regularly use open fires to stay warm outdoors during camping trips or use fireplaces in homes to keep the house warm during the winter. Even gas burning central heating units ignite a flame and use its heat to warm air that is then blown into the home through ducts by a fan.Light * Perhaps one of the most important uses of fire throughout history has been its ability to provide light. Fire is a good light source although it pales in comparison to other sources, such as light bulbs and flashlights for some purposes. It does, however, provide a soft glow that can help light an area and make it possible to move around at night outdoors. In the days prior to electric lights in homes, fire was a main source of light used in fireplaces and oil lanterns. Cooking * Fire can be used to prepare foods in many ways.Open fires have long been used to roast meats and vegetables while grills use flames to prepare favorite foods like steaks, hamburgers, hot dogs, fish and much more. Many people prefer grilling to oven roasting or frying because of the distinct smoky flavor it produces. Fire is also the catalyst for smoking meats. This method of flavoring and preserving meats has been around for generations. Gas ranges also use open flames for cooking. Energy * Every time you turn on a light in your home, flick on the air conditioner, watch television or use any other appliance, there is a good chance you have fire to thank for the luxury.While it doesn’t seem apparent to many people, electricity does not magically occur without an energy source. According to the Polymer Science Learning Center website, the vast majority of electricity in the U. S. comes from the burning of fossil fuels. Fuels such as coal, natural gas or oil is burned to heat water and produce steam that builds pressure and forces turbines to turn, creating energy that supplies electricity to the public. Fire is at the root of the process, and, without it, much of the current electrical availability across the country and much of the world would not exist. Blacksmithing Trades such as blacksmithing and other more modern metal forging operations rely on fire to produce extreme heat to help shape raw materials into new objects. Landscaping * A common use for fire is to aid in landscaping. Burning brush or burning raked leaves is a common task accomplished by many homeowners and landowners, and these tasks require fire.
