Earlier this year, Hubble Telescope found a Megmaser that was around 100 times brighter than the Maser found in our galaxy i.e. Milky Way galaxy. So, you must be wondering What are Megamasers, How do they look like and Why NASA is so excited about them. Here, we have everything about Megamaser that you should know. Continue reading What are Megamasers? Why everyone is so excited about them?
Hirudo medicinalis (a European medicinal leech) was earlier used in Leech Therapy ( classified as Blood Letting). Leech Therapy was used for the removal of blood from a patient body. The first description of Leech Therapy was found in the text of Sushruta Samhita, written by Sushruta in 800 B.C. who was also considered “the father of plastic surgery”. Diseases, where leech therapy was indicated, were skin diseases, sciatica, and musculoskeletal pains. Continue reading Hirudo medicinalis – An Old Medicine is New.
Southern Blotting is an elegant technique that can be used to identify the locations of genes and other DNA sequences on restriction fragments separated by gel electrophoresis. This technique is named after the Edwin Southern (1975) who developed it. Continue reading What is Southern Blotting? How it is used to identify Specific DNA Sequences?
In Industrial Microbiology, microbes are used to synthesise a number of products valuable to human beings. This Industry has provided products that have profoundly changed our lives and life spans. These products include beverages, food additives, products for human and animal health, and biofuels. Continue reading 11 Industrial Products that are derived from Microbes.
Antibiotic Resistance is a term that appears to be like some super terms used in some science fiction movies. But this term is something of which we should be afraid of because antibiotic resistance and spread of drug-resistant pathogens are one of the most serious and dangerous threats to public health in this 21st century. Continue reading What are the different Causes of Antibiotic Resistance?
With the use of high–yielding varieties of crops, the use of fertilizers and pesticides has increased a lot. Excess fertilizers may mix with surface water and may get drained into water bodies (surface runoff). These fertilizers overstimulate the growth of algae, causing eutrophication, and robbing the water of dissolved oxygen vital to other aquatic life. During the past century, lakes in many parts of the earth have been severely eutrophied by sewage and agricultural and industrial wastes. Continue reading What is Eutrophication? What are its Causes & Effects?
The cells of an embryo get their roles when they are capable of differentiating autonomously in a neutral environment such as petri dish or test tube. (the environment is neutral with respect to the development pathway.) This process of giving different roles to embryonic cells is called Cell Specification. Continue reading How do cells in Embryo get their Roles to Play?
In 1868, T. H. Huxley described protoplasm as the “physical basis of life”. Protoplasm is a clear, colorless and jelly-like substance which seemed to make up the contents of the cell. It was also described as “substance of life” or “living material”. Continue reading What is the physical basis of life?
