Identifying individual animals in the wild has long meant tagging, branding or clipping. For amphibians, the standard approach has often been toe-clipping, a procedure that can affect survival, physiology and behavior. A new study suggests that, for at least one species of treefrog, nature has already provided a more humane solution: the eyes.

Light-based method enables precise control of ultrafast electron flow in a scanning tunneling microscope
What would it take to watch an electron move through a material? Researchers would need to see individual atoms and capture an electron's motion at incredibly short timescales. A Technion-led team has brought those two capabilities together in a scanning tunneling microscope, usi
