Generate a photorealistic image of a woman, upper body, working in a science laboratory. She is in her early thirties, wearing a white lab coat, safety glasses, and gloves. She's holding a beaker or test tube, her expression focused and serious. Her hair is pulled back into a neat bun. The background should include lab equipment, such as microscopes, beakers, and other scientific instruments, slightly out of focus. The lighting is bright and sterile, typical of a lab environment. Include details like the markings on the glassware, the texture of the lab coat, and realistic skin imperfections. The image should convey a sense of intelligence and precision. Focus is from mid-torso up.
