Researchers at OIST and University of Turin developed a general formulation for mixing heavy particles with fluid, enabling study of fundamental physics phenomena and applied research in fluid engineering. Simulations reveal the formation of sediment plumes and the role of friction in particle interactions.
Researchers have discovered that the flight patterns of birds can be used to estimate fine-scale environmental conditions and turbulence levels. The team measured bird altitude and motion using GPS and data loggers attached to pigeons, finding a correlation between the birds' behavior and turbulence strength.
Researchers find that high-energy lepton plasma flows can accelerate interstellar ions in a two-stage process, with the first stage driven by the Weibel instability and the second stage involving collisionless shock waves. This discovery has implications for our understanding of cosmic ray generation.
Researchers have successfully split a single atom into its two halves, pulled them apart and reunited them again. This achievement showcases the potential of quantum mechanics in simulating complex systems, such as topological isolators and photo¬synthesis.
Researchers study soccer heading to understand cognitive decline and long-term brain damage risks. The study found linear accelerations of 15-20 G's and angular accelerations of 1,000-2,000 radians per second squared, values below established injury thresholds.
Researchers found that roller coaster G forces, twists, and speeds are not sufficient to injure the brain of healthy riders. They calculated peak head accelerations in three directions and found they were well within established safety margins.
