Biological fluid dynamics is a research area that applies the principles and methods of fluid mechanics to analyze flows generated by, within, or around living organisms across scales from subcellular to ecological. It investigates how fluid properties, boundary conditions, and flexible or actuated biological structures interact to determine transport, locomotion, feeding, signaling, and morphogenesis in systems such as blood circulation, ciliary flows, microorganism swimming, plant transpiration, and animal flight or swimming. The field integrates continuum mechanics, low- and high-Reynolds-number hydrodynamics, nonlinear dynamics, and computational modeling with experiments to elucidate biophysical mechanisms and to inform biomedical and bioinspired engineering applications.
In the social media age, there is little doubt about who is the star of the animal kingdom. Cats rule the screens just as their cousins, the lions, rule the savanna. Thanks to Erwin Schrödinger, this feline also has a place ...

A trio of chemists at the University of Copenhagen has developed an AI application that can be used to figure out the phase of x-rays that crystals have diffracted as part of efforts to predict the structure of small molecules.
A research team led by Dr. Li Yunlong at the Shenzhen Institute of Advanced Technology (SIAT) of the Chinese Academy of Sciences delved into the origins of nonlinear current response in polycrystalline metal halide perovskite ...
