New modular, spring-like devices maximize the work of live muscle fibers so they can be harnessed to power biohybrid bots.

The realistic model could aid the development of better heart implants and shed light on understudied heart disorders.

Reptiles don’t generally care for their offspring, but some pterosaurs may have bucked the trend.

Revisions to the CDC’s developmental milestone checklists removed crawling as a skill that babies pick up at a typical age. A biomedical engineer describes how more research may clarify its role.

When we tweaked the simulator, talented players naturally adapted.

Rather than start from scratch after a failed attempt, the pick-and-place robot adapts in the moment to get a better hold.

The soft robotic models are patient-specific and could help clinicians zero in on the best implant for an individual.

Counterintuitively, cells move faster in thicker fluids. New research on breast cancer cells explains why, and reveals the role that fluid viscosity plays in metastasis.

Players can optimise their energy resources by adopting different styles when running in short bursts or longer periods.

During a virtual Harvard Science Book Talk, Raghuveer Parthasarathy examines the mysteries covered in his new book, “So Simple a Beginning: How Four Physical Principles Shape Our Living World.”
