Bridges-2 Sims Shed Light on the Echoes of Toothed Whales

by Ken Chiacchia | Jul 3, 2024 | Bridges-2, Research, Science Highlights

By Kimberly Mann Bruch, SDSC Communications, and Ken Chiacchia, PSC Virtual Dolphin Head Shows How Sound Moves through the Skull, Suggesting How Sounds May Offer Directional Cues for Navigation and Detection Whales navigate, find food, and communicate over vast...
Voltage-sensing Protein Moves in Unexpected Ways in Anton Simulations

Voltage-sensing Protein Moves in Unexpected Ways in Anton Simulations

by Ken Chiacchia | Jun 3, 2024 | Anton 2, Research, Science Highlights

This image shows the complexity of simulating the functional movements of the voltage-sensitive phosphatase’s motions. Anton 2 enables scientists to reproduce the movements of the protein’s components, as well as the lipids (grey, with the headgroups colored), water...
Representation Matters in AI-Generated Images

Representation Matters in AI-Generated Images

by Ken Chiacchia | May 24, 2024 | AI, Bridges-2, Science Highlights

A prompt for Mexican dancers from an AI image generator produced the strange ballerinas at left; a new CMU-designed filter makes the image more appropriate and realistic, right. Image credit: Zhixuan Liu, Jean Oh, et al. 2024. SCoFT: Self-Contrastive Fine-Tuning for...
Bridges-2 Simulations Target Role of Red Blood Cells in Clot Formation

Bridges-2 Simulations Target Role of Red Blood Cells in Clot Formation

by Ken Chiacchia | May 2, 2024 | Bridges-2, Science Highlights

Developing blood clot, with fibrin “cables” (yellow), being pulled together by platelets (off-white). Clots that trap more red blood cells (red) may not contract as effectively, slowing healing. Adobe Stock image: 240_F_453411695_2N2Jddctb1vWwqowio9hVtKoNrZ76X65.jpg...
Surface Curvature Directs Growth of Bacterial Biofilms

Surface Curvature Directs Growth of Bacterial Biofilms

by Ken Chiacchia | Mar 26, 2024 | Bridges-2, Science Highlights

Simulated bacteria growing on a flat surface (left) versus on a sphere (right). The simulation recreates the growth of real bacteria raised in the lab; it also shows that when the microbes grow on progressively smaller curved surfaces, the areas of alignment become...
