Telomeres are vital nucleotide sequences at both ends of each chromosome, and their
motion reports on the local dynamics of decondensed chromatin in the nucleus of interphase …

Recent experiments reveal both passive subdiffusion of various nanoparticles and
anomalous active transport of such particles by molecular motors in the molecularly crowded …

The healthy growth and maintenance of a biological system depends on the precise spatial
organization of molecules within the cell through the dissipation of energy. Reaction …

Cell movement—for example, during embryogenesis or tumor metastasis—is a complex
dynamical process resulting from an intricate interplay of multiple components of the cellular …

Single particle tracking has become a standard method, especially in biophysics (1, 2). With
superresolution microscopy, the motions of even individual molecules in a live cell are …

Subdiffusive motion of tracer particles in complex crowded environments, such as biological
cells, has been shown to be widespread. This deviation from Brownian motion is usually …

The cytoplasm and biomembranes in biological cells contain large numbers of proteins that
cyclically change their shapes. They are molecular machines that can function as molecular …

The focus of many particle tracking experiments in the last decade has been active systems,
such as living cells. In active systems, the particles undergo simultaneous active and …

The translational motion of small molecules in cells appears to be suppressed compared to
what is observed in dilute solutions. Although, the rotation of small proteins is almost …

In multicellular organisms and complex ecosystems, cells migrate in a social context. While
this is essential for the basic processes of life such as embryonic development, wound …
