As AI—and the ethical debate surrounding it—accelerates, scientists argue that understanding consciousness is now more urgent than ever. Researchers writing in Frontiers in Science warn that advances in AI and neurotechnology are outpacing our understanding of consciousness—with potentially serious ethical consequences.
Writing in the journal National Science Review, researchers present a multichamber magnetic capsule robot for performing multiple tasks in the digestive tract. By applying external programming magnetic fields, its four independent chambers can be selectively opened, allowing for sampling bodily fluid or releasing drug at multiple sites or times via one-time oral intake. This design significantly improves patient comfort and procedural efficiency, demonstrating promising potential for clinical application.
A new review highlights major advances in bio-hydrovoltaic technology, marking a shift from traditional non-living materials to living biological systems that generate electricity through metabolic processes. This revolutionary energy approach offers self-regulation, environmental adaptability, and biodegradability, with strong potential in wearables, environmental monitoring, and distributed energy networks. Future directions include a “hydrovoltaic internet,” “hydrovoltaic intelligence,” and “hydrovoltaic ecology,” while key challenges remain in material stability, scalable manufacturing, and biosafety.
