Scientists from the Indian Institute of Science Bangalore devise a computational model to study how cooperation evolves in natural systems - from cells to large mammals. The study finds mobility, which was largely ignored before, plays a key role in the evolution of cooperation. Understanding mobility of cells in a medium could help us understand better the spread of cancer.
Researchers engineer minuscule particles that use light to break down dyes and sense vital chemicals, paving the way for cleaner water and better diagnostics.
