Scientists have developed a 3D, AI-based tool for viewing hearing cells. To understand hearing damage from noise and aging, and develop new treatments, scientists need detailed images of hair cells. The new VASCilia tool uses deep learning to accelerate sensory cell image processing and analysis.
Why do some groups get smarter together while others collapse into groupthink? New research from University of Pennsylvania theoretical biologist Joshua Plotkin and collaborators show that collective intelligence doesn’t emerge by rewarding the most accurate individuals but by rewarding those who improve the group’s prediction as a whole.
No ears, no problem! The tobacco hornworm caterpillar, a common garden pest, can actually detect airborne sound via microscopic hairs on its body, according to a team of faculty and graduate students at Binghamton University, State University of New York. The research could have implications for improving microphone technology.
