Simple ballpoint pen can write custom LEDs

Researchers working with Chuan Wang, at the McKelvey School of Engineering, have developed ink pens that allow individuals to handwrite flexible, stretchable optoelectronic devices on everyday materials including paper, textiles, rubber, plastics and 3D objects. The study is published in Nature Photonics.
Hormone alters electric fish’s signal-canceling trick

Hormone alters electric fish’s signal-canceling trick

New research from Washington University in St. Louis shows that testosterone — which naturally triggers male electric fish to broadcast slightly different signals during the breeding season — also alters a system in the fish’s brain that enables the fish to ignore its own signal. The study by biologists Matasaburo Fukutomi and Bruce Carlson in Arts & Sciences is published in Current Biology.

Good smells, bad smells: It’s all in the insect brain

Good smells, bad smells: It’s all in the insect brain

Barani Raman and his lab at the McKelvey School of Engineering studied the behavior of the locusts and how the neurons in their brains responded to appealing and unappealing odors to learn more about how the brain encodes for preferences and how it learns.

Analyzing generative AI’s copyright crisis

Artificial intelligence tools like ChatGPT and Copilot offer helpful assistance to programmers, but computer scientists at the McKelvey School of Engineering have shown that both open-source and commercial AI platforms frequently generate copyright-infringing content.
Brain movement measured for clues to prevent, reduce injury

Brain movement measured for clues to prevent, reduce injury

Philip Bayly and Jordan Escarcega at the McKelvey School of Engineering led a multi-institutional team to compare how the human brain deforms in response to movement using two types of magnetic resonance imaging. Such deformations are key to understanding traumatic brain injury but are challenging to study since the brain is hidden inside the skull.
