Airborne Spiders Drift on Multiple Silk Threads
Simulations reveal new details of the way spiders can fly by exploiting the electric field present in the atmosphere. Continue reading
Ultrasound Imaging of Brain with Machine Learning
A proposed machine-learning technique can convert ultrasound signals into a skull profile, which could lead to noninvasive imaging for medical treatments in the human brain. Read more in APS Physics…
Shape-Shifting Proteins Follow Diffusion Rules
How quickly a protein diffuses in a liquid depends directly on its radius, which changes as the protein’s conformation fluctuates. Continue reading
Evolutionary insights into shape-shifting proteins
Over millions of years a protein that now folds into two stable structures likely favored first one configuration, then the other, before settling on both. Continue reading
Evolutionary insights into shape-shifting protein
A protein that has two stable structures likely evolved from an ancestor that had only one. Continue reading
A Vortex in an Egg Cell
During a fruit-fly egg cell’s early development, its internal fluid begins to swirl in a vortex—a transition caused by the coordinated behavior of elastic filaments in the cell. Continue reading
Active Particles Map to Passive Random Walks
Researchers make systems of self-propelled particles produce the same large-scale dynamics as passive-particle systems. Continue reading
