Nocturnal moths rely on hearing to escape predatory bats, yet how they respond to different bat calls has remained unclear. In a new study, researchers from Japan exposed moths to ultrasonic pulses simulating bat hunting stages and observed their flight and egg-laying behaviors. The study found that moths change how they fly and lay eggs depending on the level of danger, a finding that could help develop ultrasonic methods to protect crops from moth damage.

An international study led by the University of Basel has discovered that nuclear pore complexes – tiny gateways in the nuclear membrane – are not rigid or gel-like as once thought. Their interiors are dynamically organized, constantly moving and rearranging. The findings reshape our understanding of a vital transport process in cells and have implications for diseases and potential therapies.
