Ionotropic glutamate receptors comprise two conformationally different A/C and B/D subunit pairs. Closed channels exhibit fourfold radial symmetry in the transmembrane domain (TMD) but transition to ...
Neurons in the rodent central nervous system originate from three classes of neural stem and progenitor cells — neuroepithelial cells, radial glial cells and basal progenitors. These cells undergo ...
(a) TEM image of the ultra-fine NiS nanorods with diameter of ~2.7 nm. (b) ADF-STEM image and (c) corresponding FFT pattern of the ultra-fine nanorod in radial direction. (d) ADF-STEM image and (e) ...
Starfishlike brittle stars have five thin arms and no central brain, but even so, they move in a carefully coordinated fashion similar to four-limbed animals (including humans). A new analysis delves ...
Symmetry in biology is the balanced distribution of duplicate body parts or shapes. The body plans of most multicellular organisms exhibit some form of symmetry, either radial symmetry or bilateral ...
A poet finds artistic inspiration in her work as a scientist and new perceptions in the lines and linkages of her art. From flies landing on food to the retraction of the controversial arsenic-life ...
