Some people head for the mountains for a sabbatical.
Others go abroad for a change of scene. This fall and winter, immunologist Pat Jones is taking two quarters off for the pleasure of having nothing to do but walk through the side door of her office, into her own laboratory on the third floor of Gilbert Hall. When Jones talks about science, she cannot stay in her chair. She's up and reaching to sketch on a white drawing board on her office wall, switching from red to blue markers to diagram the parts of the immune system that she works on in the lab helper T-cells and voracious macrophages. The chase is on.
