The modeling and simulation of self-organized intracellular twisters in the Drosophila oocyte

Cytoplasmic streaming is the large-scale motion of cytoplasm (i.e., gelatinous liquid inside cells) inside a living cell. This flow, known to regulate various intracellular processes, can vary greatly between different cell types at different stages.....»»

CERN researchers measure speed of sound in the quark–gluon plasma more precisely than ever before

Neutron stars in the universe, ultracold atomic gases in the laboratory, and the quark–gluon plasma created in collisions of atomic nuclei at the Large Hadron Collider (LHC): they may seem totally unrelated but, surprisingly enough, they have somet.....»»
