An international team of scientists reports producing a form of germanium that is superconducting—able to conduct electricity with zero resistance, which allows currents to flow indefinitely without energy loss, resulting in greater operational speed that requires less energy. 

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 project led by the Germans Trias i Pujol University Hospital and Research Institute has developed an AI-based facial recognition system, AcroFace, capable of detecting early signs of acromegaly with 93% accuracy. The researchers are now conducting a larger pilot study with 4,000 images from the general population to confirm these promising results and improve early diagnosis of this rare disease.

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.

Under ultraviolet irradiation, water molecules can generate highly oxidative hydroxyl radicals (Ultraviolet-water/UV-W), which can scissor polymer chains. The study results reveal that by first introducing water passages into the polymer membrane and subsequently applying the UV-W process, tunable angstrom-sized channels can be created, enabling precise ion sieving.

With a newly developed method that compares AI-generated protein sequences with naturally occurring ones, function- and structure-regulating amino acids can be determined much more precisely than before.
