Sickle Cell Anemia May 3 2011
Description
Discover sickle cell anemia, a genetic disorder caused by a mutation that forces red blood cells to warp their shape and obstruct blood flow within the capillaries. The video demonstrates how a defect in the hemoglobin protein transforms flexible cells into rigid, sickle-like structures. It also explores the fascinating evolutionary link between this hereditary disease and a natural resistance to malaria.

אנמיה חרמשית (3 במאי 2011)
הכירו את מחלת האנמיה החרמשית, שנובעת משינוי גנטי הגורם לכדוריות הדם האדומות לשנות את צורתן ולחסום את זרימת הדם בנימים. הסרטון מדגים כיצד פגם בחלבון ההמוגלובין הופך את התא הגמיש למבנה קשיח דמוי חרמש ובוחן את הקשר המרתק בין המחלה התורשתית לבין עמידות למלריה.

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
