Nipah virus outbreak: What are monoclonal antibodies?

Context: Recently, India reached out to Australia to procure monoclonal antibody doses to combat the Nipah virus outbreak in Kerala. The dosage has to be administered at an early stage of infection. What is an antibody? What is a monoclonal antibody? How do monoclonal […]

What is the Human microbiome?

Context: The microbiome research has gone from a ‘niche subject area’ to ‘one of the hottest topics in all of science’. Researchers have thrown light into the human microbiome — the community of microbes living in the human body. Human Microbiome: Benefits of Microbiome: […]

Hybrid Nanoparticles to target Cancer cells

Context: Scientists at the Indian Institute of Science (IISc) have developed a new approach using hybrid nanoparticles to potentially detect and kill cancer cells, especially those which form a solid tumour mass. The researchers have tested the nanoparticles on lung cancer and cervical cancer […]

Genetic engineering gives mosquito control an upgrade

Context: With insecticide resistance in mosquitoes rising to alarming proportions, it has become imperative that newer approaches to mosquito control gain prominence. Gene-drive technology is one such approach, which has been used in outdoor trials in India, Brazil, and Panama. Background: Restraining Mosquito Population […]
