World of Biology on Instagram: "Pinocytosis is a cellular process where the cell engulfs small molecules and extracellular fluids, bringing them into the cytoplasm. In this animation, these solutes are represented as small spheres. The term “pinocytosis” comes from “pino,” meaning “drinking,” and it's often referred to as the cell’s way of “drinking” its environment. It’s one of the three main types of endocytosis. The internalized fluid is enclosed in tiny vesicles formed from the cell membrane

Rowan Cheung on Instagram: "OpenAI has developed a specialized AI model that successfully redesigned Nobel Prize-winning proteins to reverse cellular aging with 50-fold greater efficiency. Working with longevity startup Retro Bio, researchers used GPT-4b micro, a model trained on biological data rather than text, to reengineer Yamanaka factors, proteins that reprogram adult cells into stem cells. The original 2012 discovery converted less than 0.1% of cells over weeks, but the AI-designed versio
