A realistic model of the connections between local populations of neurons in the adult mouse brain can be constructed based on just two biologically plausible rules.

A new taxon from the Late Jurassic of southern Germany represents the second volant bird known from that time period and documents the improvement of flapping flight in bird evolution.

The results here show that Stu2 binds kinetochores by associating with the Ndc80 complex and that the interaction is critical for accurate chromosome segregation during cell division.

By distributing receptor-binding and receptor-destroying proteins asymmetrically on their surface, filamentous influenza A virus particles create a Brownian ratchet that facilitates their passage through mucus.

Human chromosome-microtubule attachments are stabilised by Astrin-mediated dynamic delivery of PP1 phosphatase to the attachment site, which ensures the normal segregation of chromosomes.

The immune effector Drosomycin buffers stress signaling in hypertrophic salivary glands to inhibit their disintegration, detection by the cellular immune response, and promotes further overgrowth.

Multiple age-related changes in chromosome architecture could explain why human oocyte aneuploidy increases with advanced maternal age.

The chromosomal passenger complex interacts with the inner kinetochore COMA complex through the Ctf19 C-terminus in vitro which is shown to be important for mediating accurate chromosome segregation.

A cell surface receptor called Ret enables neurons to establish and maintain the organized arrays of dendrites that support communication between neurons.

A designed system to track homologous recombination (HR) in vivo demonstrates the importance of chromosome organization in the induction of global mobility in response to double-strand breaks and characterizes the role of two types of global motility in HR.
