Angiogenesis May 3 2015
Description
Angiogenesis is the physiological process of forming new blood vessels from existing ones, playing a critical role in wound healing and embryonic development. However, this process also has a destructive side, as cancerous tumors exploit it to nourish themselves and metastasize to other organs. Understanding these molecular mechanisms allows scientists to develop drugs that inhibit the process in order to "starve" the tumor.

אנגיוגנזה (3 במאי 2015)
אנגיוגנזה היא התהליך הפיזיולוגי של יצירת כלי דם חדשים מתוך כלי דם קיימים, הממלא תפקיד מכריע בריפוי פצעים ובהתפתחות עוברית. עם זאת, לתהליך זה יש גם צד הרסני, שכן גידולים סרטניים מנצלים אותו כדי להזין את עצמם ולשלוח גרורות לאיברים אחרים. הבנת המנגנונים המולקולריים הללו מאפשרת למדענים לפתח תרופות המעכבות את התהליך במטרה "להרעיב" את הגידול.

Daniel Asks: Why Are We Afraid of the Dark
Credit: מכון דוידסון לחינוך מדעיThe fear of the dark is an ancient evolutionary survival mechanism designed to protect us from predators lurking in places we cannot see. Our brains tend to fill in missing visual information with our imagination, which triggers a sense of danger and anxiety in children and adults alike. Understanding the evolutionary roots of this fear helps us confront it in a more rational and calming manner.2:48

Floating Paintings
Credit: מכון דוידסון לחינוך מדעיDiscover how to bring your drawings to life using nothing more than a whiteboard, water, and an erasable marker. This experiment demonstrates the unique properties of dry-erase ink, which is insoluble in water and does not adhere strongly to surfaces. This lack of adhesion allows the drawing to detach in one piece and float on the water's surface, powered by the force of buoyancy.4:09

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
