Subject: Science and tech Context : Department of Telecommunications (DoT) is all set to direct telecom companies to undertake an “information security audit” of their networks and submit the report by October end Concept : An information security audit is a step-by-step assessment of the complete network infrastructure which checks for the equipment installed and […]
Subject: Science and tech Context: The department of Telecommunications (DoT) is set to direct all telecom operators to undertake an ‘information security audit’ of their networks and submit the report by October end. Concept: A ‘backdoor’ or a ‘trap door’ is a bug installed in the telecom hardware which allows companies to listen in or […]
Subject: Science and tech Context: Researchers have shed new light on the dwarf planet Ceres which now has the status of an “ocean world”, after scientistsanalysed data collected by NASA’s Dawn spacecraft. Concept: There are officially five dwarf planets in our Solar System. The most famous is Pluto, downgraded from the status of a planet […]
Subject: Science and tech Context : A new, rapid diagnostic test for the novel coronavirus that uses saliva samples was granted an emergency use authorisation by the U.S. Food and Drug Administration (FDA). Concept : The inexpensive test called SalivaDirecthas high sensitivity and can detect the virus even when the number of virus copies in […]
Subject: Science and tech Context: SARS-CoV-2-specific T cell immunity prevents recurrent severe COVID-19 disease Concept: T cells (also called T lymphocytes) are one of the major components of the adaptive immune system. Their roles include directly killing infected host cells, activating other immune cells, producing cytokines and regulating the immune response. There are two major types […]
Subject: Science and tech Context: In August 1970, in a paper in Nature, relativist C. V. Vishveshwara first published a calculation and plot of the signal that would be given out by a single perturbed back hole. Concept: Black hole refers to a point in space where matter is so compressed as to create a gravity field from […]
Subject: Science and tech Context: An old drug formulation — RLF-100 — is being probed to treat Covid-19 patients after initial studies have shown that the drug is able to halt SARS-CoV-2 virus replication in lungs. Concept: RLF-100, also called Aviptadil, is a formulation of synthetic human Vasoactive Intestinal Polypeptide (VIP). VIP is released throughout the […]
Subject: Science and tech Context: ISRO recently released some images of the Moon captured by Chandrayaan-2 and one of the craters has been named after Vikram Sarabhai, the father of the Indian space programme Concept: Sarabhai crater is about 250 to 300 kilometres east of the crater where the Apollo 17 and Luna 21 Missions […]
