Quantum supremacy refers to quantum computers being able to solve a problem that a classical computer cannot. In the research paper, Google used a 53-qubit processor to generate a sequence of millions of numbers. Though these numbers appeared randomly generated, they conform to an algorithm generated by Google. A classical supercomputer checked some of these … Read more

Stem cells are special human cells that have the ability to develop into many different cell types, from muscle cells to brain cells. In some cases, they also have the ability to repair damaged tissues.               Stem cells differ from other kinds of cells in the body. Self-renewal: They can divide and renew themselves for … Read more

Adaptive immunity develops when innate immunity is ineffective in eliminating infectious agents and the infection is established. The primary functions of the adaptive immune response are the recognition of specific “non-self” antigens in the presence of “self” antigens; the generation of pathogen-specific immunologic effector pathways that eliminate specific pathogens or pathogen-infected cells; and the development … Read more

Stem Cells: Stem cells are a class of undifferentiatedcells that are able to differentiate into specialized celltypes. Commonly, stem cells are of the followingtypes: Embryonic stem cells – derived from the inner cellmass of an embryo and these are capable offorming any cell types of the bodyAdult stem cells – also known as somatic stem … Read more
