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?
Several Bacteria (like Escherichia Coli) exhibit a form of sexual reproduction called Bacterial Conjugation. It is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells. It was discovered by Nobel Prize winners, Joshua Lederberg and Edward L. Tatum in 1946.

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?
