Deinococcus radiodurans was discovered in 1956 by scientists accidently, after a can of corned beef had been treated with radiation in order to kill any harmful microorganisms that might have been present in the canned meat. Since its accidental discovery, D. radiodurans has been intriguing scientists with is astonishing resistance to ionizing radiation, UV radiation, electrophilic mutagens, oxidizing agents, and desiccation. This gram-positive bacteria usually forms in spherical pairs or…

To Drill or Not to Drill: An Environmental Perspective Environmentalists have long struggled with the government to protect wildlife and open lands. In March 2013, The USGS established that there are approximately 10.4 billion barrels of undiscovered oil in the arctic. (Irwin) Ever since Shell and other companies began to show interest in drilling oil, native communities and environmental groups such as Earthjustice, Alaska Wilderness League and Friends of Earth Climate Campaign have began…

HISTORY OF RIVER RAVI Ravi River, the littlest waterway of the stream Indus framework was among that were given to India when the Indus Water Treaty was agreed upon. Ravi River is one of the five floods of stream Indus that has lead to the area 's name Punjab (signifying "Five Rivers"). It is arranged in the northwestern piece of India and north eastern piece of Pakistan. Waterway Ravi emerges from the Himalyas in Himachal Pradesh state, India and travels through west-northwest Chamba, going…

Genetically modified organisms is a controversial topic that has been on people 's minds in the past couple of years, but lots of people don 't know what genetically modified organisms actually are or what they 're used for. Many people think they’re terrible things in food that are going to kill us one day, but they don 't know very much else. Everyone should know what genetically modified organisms are, why they are used, pros, cons, and why is it controversial, so that they can form their own…

(NO3-)-reducing bacteria is mainly have habitat in freshwater and marine environments. They play significantly affect in the biogeochemical cycling of carbon, hydrogen and variety of trace metal elements. Nitrate(NO3-)reducing bacteria are important for bioremediation purpose. It acts as oxidizing toxic organic compounds to carbon dioxide (CO2) and reduce immobilizing radionuclides…

Pro GMOs Introduction In 1996, Genetically Modified Organisms (GMO) were presented to people. Since then there have been vivid disputes about usefulness and safety of GMOs. Important question here is whether these genetically modified organisms are dangerous to people’s health and environment. Another issue is whether the humankind needs GMO to survive food crisis or whether it can do so without intervening the nature. Thus, there are both proponents and opponent to the relevance of using GMO.…

BACTERIOPHAGE MEDIATED PHYTOREMEDIATION Wastewater is any water that is against the usage by human . Wastewater is the result of domestic, commercial, industrial or agricultural activities. After the use water is returned to the environment in a different condition, usually as dirty water (wastewater).It is never returned in the same way as it was withdrawn. Wastewater produced by households or communities is also called municipal wastewater or sewage. (Tilley) Effluent refers to the sewage or…

My fascination with the neurological basis of learning and memory began during an independent research project in the second year of my master’s degree at Bangalore University. I was in awe when I realized how extraordinarily complex the neural mechanisms that support memory formation are and yet these profound neural events may be “undone” if the memories are not retrieved. Furthermore, I learned that memories can be embedded in chains, or “engrams”, composed of antecedent and subsequent events…

effect of the CRCQL v. Seif case was that, “…the EPA concluded that the health risks caused by environmental hazards in Chester are ‘unacceptably high’…”, and during the trial the DEP denied a permit to a company to create a contaminated soil bioremediation plant in Chester, which stood as the first time the DEP denied a pollution permit to a corporation that selected Chester (Public). As small as this victory this was, it set the scene for further work and today Chester, Pennsylvania is cleaner…
