Mitochondria are often described as cellular power plants, but they are also signaling hubs whose activity is tightly regulated. Forcing them into a state of continuous stimulation reveals a complex tradeoff between energy output, oxidative damage, and long-term metabolic stability.

Our solar system is currently drifting through a tenuous region of interstellar material, and Earth is collecting microscopic grains from it. New measurements and models suggest this passage shapes the heliosphere, alters cosmic ray exposure, and leaves traces in deep-sea sediments and polar ice.
The coding agent category is shifting from single-shot autocomplete tools toward multi-agent systems that plan, execute, and critique their own work. This change is reshaping how labs differentiate their products and how developers integrate AI into real engineering workflows.
