Will Moths Inspire a New Kind of Microphone?

Share This Post

Directional hearing, the ability to determine the direction a sound comes from, is important for living beings. Unlike large animals that have directional hearing because their ears are far apart, insects have differently structured ears. The lesser wax moth is one example. Scientists discovered that its elliptical ear structure and its differing thickness allow the lesser wax moth to hear directionally despite its ears being only 600 micrometres apart. The simplicity of this solution could inspire new directional audio technology, like microphones and hearing aids. Read full article here

Magneto Protein Could Help Magnets Control Brain Circuitry

This groundbreaking research by scientists at the University of Virginia has demonstrated a novel way to control the nervous systems of zebrafish and mice using magnets. This method, called magnetogenetics, involves inserting genetic constructs into neurons to make them sensitive to magnetic fields, providing a more precise and non-invasive way to control and manipulate neural circuits than traditional methods. This could one day revolutionize the treatment of brain disorders in humans. Read full article here
