The Mesozoic Era started about 225 million years prior to the present era, the amphibians were declining after a long period of supremacy among the animals and the reptiles were gradually replacing them. Many of them became very large fearsome and came to dominate the animal life practically everywhere. As a result, giant reptiles, dinosaurs, and other monstrous beasts become very abundant and spread into all habitats. For this reason, the Mesozoic era is also called the Age of Reptiles or the Age of Dinosaurs. Continue reading Mesozoic Era – the Age of Reptiles.
The Kingdom Protista includes diverse kinds of predominantly water-dwelling unicellular eukaryotic microorganism. Protists, like Monerans, have an immense reproductive potential. In an optimal environment, they may reproduce several times a day. This is mainly by asexual reproduction, using the process of mitosis. However, they also reproduce sexually. Continue reading Sexual Reproduction – An Important Innovation of the Early Protists.
Long pepper (Piper longum), sometimes called Indian long pepper (pipli), is a flowering vine in the family Piperaceae. It is cultivated for its fruit, which is usually dried and used as a spice and seasoning. The dried fruit of Piper longum is a slender, aromatic plant with creeping jointed stems and perennial woody roots. It is used to make medicine. Indian Long pepper has a taste similar to, but hotter than, that of its close relative Piper nigrum. Continue reading Indian Long Pepper: A Potential Cancer treatment Drug.
In recent times, the people of India have been heard talking about gene sequencing, gene editing, gene sequencing, and many other similar terms. It seems like, they are now getting introduced to the idea and principle behind personal genomics. Continue reading Personal Genomics: Gene Sequencing & Analysis in India.
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.
From the beginning of time, people have tried to understand aging and processes associated with the biology of aging. Many scientists believe that aging results from the repetitive damage caused to our body cells. The everyday metabolic activities that usually sustain our life but also create “metabolic stress”, which over time, results in damage to our bodies. Some of these metabolic activities result in the production of radicals and which may cause harmful damage to our body cells. Continue reading Free Radicals: What is their role in making us old?
The origin of new species from the existing one is called Speciation. It occurs when a group within a species migrates to a new area with different environmental conditions and develops its own unique features. Speciation has taken place over the course of evolution and may have played an important role in driving biodiversity on planet Earth. Continue reading What is Speciation?
Euglena is a large Genus of unicellular Protists, which belongs to phylum, Euglenaceae. Thousands of species of Euglena are present in ponds, lakes, streams and also in the waterlogged area such as marshes. Continue reading Euglena – A Protist with Flexible Lifestyle
