Scientists uncover a new way to forecast eruptions at mid-ocean ridges through hydrothermal vent temperatures

Woods Hole Oceanographic Institution
Peer-Reviewed Publication

A new study published in the Proceedings of the National Academy of Sciences (PNAS) provides scientists with a powerful new tool for monitoring and predicting tectonic activity deep beneath the seafloor at mid-ocean ridges—vast underwater mountain chains that form where Earth’s tectonic plates diverge.

Twisting sound: Scientists discover a new way to control mechanical vibrations in metamaterial

Advanced Science Research Center, GC/CUNY
Peer-Reviewed Publication

October 13, 2025 — Scientists at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have discovered a groundbreaking way to control sound and vibrations using a concept inspired by “twistronics,” a phenomenon originally developed for electronics. Their research, published in the journal PNAS, introduces “twistelastics”— a technique that uses tiny rotations between layers of engineered surfaces to manipulate how mechanical waves travel.

Miniature 3D-printed objects inside the body

Universitaet Stuttgart
Grant and Award Announcement

Dr. Andrea Toulouse from the Institute of Applied Optics receives €1.8 million in funding from the Carl-Zeiss-Stiftung as part of the CZS Nexus program to establish a new junior research group. She conducts research in the field of micro-optics and fiber-based 3D printing. Her vision is to develop 3D printers that will one day be able to build biological tissue directly inside the body.
