Introduction: Airplanes have revolutionized modern transportation , allowing us to traverse vast distances quickly and efficiently. But have you ever wondered how these colossal machines take flight? In this blog post, we'll delve into the fascinating science behind aviation and explain how airplanes soar through the skies. Aerodynamics: A key concept in understanding flight is aerodynamics. This branch of science deals with the study of air in motion, particularly the interaction between the aircraft and the air it moves through. Lift: Lift is the force that allows an airplane to overcome gravity and ascend into the sky. This ess ential force is generated primarily by the wings. Here's how it works: Shape of the Wings: Airplane wings are carefully designed with a curved upper surface and a flatter lower surface. This shape creates a pressure difference, with lower pressure on top and higher pressure on the bottom. As a result, the airplane gets pushed upward, creating lift. ...
viruses that can selectively target and kill cancer cells are known as oncolytic viruses . These viruses are engineered or naturally occurring pathogens that have been modified to specifically infect and destroy cancerous cells while sparing healthy ones. The concept behind oncolytic viruses is to harness the natural ability of viruses to enter and replicate within cells to combat cancer. Here's an overview of how they work and some examples: -Mechanism of Action : Oncolytic viruses are designed to be selective for cancer cells. They exploit the differences between cancer cells and normal cells, such as changes in cell surface receptors or the tumor microenvironment, to preferentially infect and replicate within cancer cells. -Replication and Destruction : Once inside a cancer cell, the oncolytic virus replicates, c...
