Gametogenesis :  The gametogenesis is the formation of gametes i.e. sperm in males and ovum in females. It is also known as spermatogenesis and Oogenesis. Insemination:        Insemination is the deliberate introduction of sperm into a female animal or plant for the purpose of impregnating or fertilizing the female for sexual reproduction. The sperm is introduced … Read more

The phenomenon of technology transfer has existed ever since the beginning of technological progress. Having significantly increased in recent years, it will probably attract the world’s attention for many years to come. Many developing countries now appear to be seeking technological progress through technology transfer to realize development in a much shorter time than that … Read more

. Today, satellites are launched into orbit by multi-staged satellite launch vehicles that can be used only once (expendable). These launch vehicles carry oxidiser along with the fuel for combustion to produce thrust. Launch vehicles designed for one time use are expensive and their efficiency is low because they can carry only 2-4% of their … Read more

LIDAR is short for Light Detection And Ranging. It’s a more modern (but still pretty old) version of the tried and true radar which is short for Radio Detection And Ranging. Radar uses radio waves to detect objects and determine their range, angle, and/or velocity while lidar does basically the same thing, but with pulsed … Read more

The term RNA interference (RNAi) was coined to describe a cellular mechanism that uses the gene’s own DNA sequence of the gene to turn it off, a process that researchers call silencing. In a wide variety of organisms, including animals, plants, and fungi, RNAi is triggered by double-stranded RNA (dsRNA). During RNAi, long dsRNA is … Read more

A concern about what affect genetically modified material could have on human health. For example, transgenic crops have been suggested to cause allergies in some people, although it is uncertain whether transgenic crops are the source of this reaction. Furthermore the antibiotic resistance genes placed in these crops has been suggested to cause resistance to … Read more

Data sovereignty is the concept that information which has been converted and stored in binary digital form is subject to the laws of the country in which it is located. The concept of data sovereignty is closely linked with data security, cloud computing and technological sovereignty.  Many countries have passed cyber laws to prevent the … Read more
