Phys.org / Engineers discover 'unexpected motion' in drug-delivery robots

One day, tiny swimming robots may travel through the human body to deliver drugs. The medication would target only areas of need—chemotherapy drugs for a tumor, for example—avoiding healthy tissue and minimizing side effects. ...

Phys.org / Researchers use AI to evaluate a systematic framework to describe molecular order in liquid water

Water is the most abundant liquid on Earth's surface, and it is highly anomalous compared with other liquids because it expands upon freezing. The anomalies in water have been linked to how its microscopic structure changes ...
