Subject: Science and tech Context: Important parameters in COVID testing Concept: Sensitivity measures how often a test correctly generates a positive result for people who have the condition that’s being tested for (also known as the “true positive” rate). A test that’s highly sensitive will flag almost everyone who has the disease and not generate […]
Subject: Science and tech Context: In a research new protein has been identified as potential cure for coronavirus Concept: PLpro, a protein is produced by the human cell itself after the virus hijacks the cell mechanism. PLpro is essential for replication of the virus. A new study in Nature has found that pharmacological inhibition of […]
