Rock-n-roll bridges, blinking eye-on-a-chip, high-flying low metabolism, & urban air “re-leaf”

The video highlights four innovative discoveries. It begins with the STEM Guitar Project, which integrates math, science, and engineering through guitar building. The first discovery involves training geese to fly in a wind tunnel, revealing their unique metabolic efficiency at high altitudes, which could have medical implications. The second discovery is a bioengineered model of the human eye, used to test new drugs for dry eye disease. The third discovery features earthquake-resistant bridges using hybrid sliding rocking columns. Lastly, the video discusses how oak trees in urban areas act as natural air filters, capturing significant amounts of black carbon particles.
