Modeling Tissue Mechanics with Molten Glass
A glass studio becomes a physics lab for biophysicists examining the physiological tissue properties of marine microorganisms. Read more in APS Physics…
Molecular Lawnmower Drives Itself
A protein-based motor uses a trimming mechanism to move forward across a field of grass-like peptide segments. Continue reading
Tension Remodeling Resolves Tissue Architecture Question
A dynamical tension model captures how cells swap places with their neighbors in epithelial tissues, explaining observed phase transitions and cellular architectures. Continue reading
Express Delivery of Proton Therapy
A new scheme could increase the efficiency of a high-dose cancer radiation therapy and mitigate patient discomfort by reducing particle loss in proton beams. Continue reading
A Broader Stance Can Stop a Sandy Slide
Experiments show that an optimal distance between points of contact helps insects and other multilegged creatures avoid slipping down a steep granular slope. Continue reading
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
