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.
Inspired by snake pit organs, we propose a CMOS-integrated upconverter system achieving room-temperature, 4K ultra-high-resolution short-wave and mid-wave infrared imaging. Utilizing colloidal quantum dot barrier heterojunctions and co-hosted emitting units, the device demonstrates superior luminance and upconversion efficiency. This innovation breaks visible light limitations, advancing applications in night vision, agriculture, and industrial inspection.
No-tillage with total green manure mulching can optimize maize root structure by improving soil water content and soil temperature environment. NTG increased maize photosynthetic capacity and grain yield. The relationship between SWC, ST, root length, photosynthetic characteristics, and grain yield was expounded.
