In this episode, we dive into the groundbreaking new technique, Dynamic Interface Printing (DIP), that’s setting a new standard in 3D printing. Imagine creating intricate, centimeter-scale structures in seconds, not hours, all without the complex chemistry and optics of traditional methods. DIP achieves this using an acoustically modulated air-liquid interface, enabling rapid, high-resolution fabrication ideal for bioengineering, medical models, and more. From tissue engineering to rapid prototyping, DIP's potential is immense, merging speed, scalability, and biocompatibility. Join us as we explore how this innovation could reshape the future of manufacturing and medical technology.

This research was led by Callum Vidler and David J. Collins from the University of Melbourne, alongside their colleagues from various departments, including Biomedical Engineering, the Florey Institute, and Physics from University of Melbourne, Australia

Let's dive deep into technology that's set to transform how unmanned aerial vehicles handle the skies. Meet FALCON—an innovative, Fourier-based control system that's rewriting the rules of stability and control in turbulent environments.
Developed by researchers from the Caltech, led by Anima Anandkumar, FALCON is designed for high-stakes applications where conventional methods fall short.

This model-based reinforcement learning framework leverages the power of the frequency domain to predict and reject disturbances in real time, making it a game-changer for UAVs, wind turbines, and beyond. Tested under extreme turbulence, it doesn’t just react; it anticipates, adapts, and excels where other methods struggle.

Tune in to explore how FALCON might be the future of adaptive flight technology, from securing drone deliveries in urban jungles to enhancing the resilience of renewable energy systems.

Researchers, using the power of AlphaFold-Multimer, have uncovered a key trimeric protein complex—Izumo1, Spaca6, and Tmem81—on sperm that is essential for sperm-egg binding. This trio forms a critical link to egg proteins such as Bouncer in zebrafish and JUNO in mammals, offering new insights into the intricate dance of fertilization. This research, featured in Cell and conducted by Victoria E. Deneke, Andreas Blaha, led by Andrea Pauli and their team, sheds light on a conserved fertilization mechanism across vertebrates and could open up new avenues in fertility treatments.
