Systemic PF4 enhances adult hippocampal neurogenesis in vivo. a Experimental design of PF4 injection paradigm in young mice. bc Intravenous (i.v.) PF4 injections for 1 week did not affect neural precursor cell proliferation in the subgranular zone (SGZ; n = 10 mice in saline group; n = 9 mice in PF4 group; counts of one hemisphere), but increased the number of doublecortin+ (DCX+) cells (n = 15 mice per group; counts of one hemisphere). d Experimental design of the double-labeling paradigm with CldU and IdU. e Acute administration of PF4 did not affect neural precursor cell proliferation, including the recruitment of cells from quiescence (n = 20 mice per group). f Running paradigm of PF4 knockout (KO) mice. g Representative images of Ki67+ cells in the S...

Star attraction: Magnetism generated by Star-like Arrangement of Molecules- Atomic-scale ‘kagome’ geometry switches on magnetism in a 2D organic material.

The star-like ‘kagome’ molecular structure of the 2D metal-organic material results in strong electronic interactions and non-trivial magnetic properties (left: STM image, right: non-contact AFM).

A new study demonstrating the emergence of localized magnetism due to a 2D nanomaterial’s unique, star-like atomic-scale structure has potential for applications in next-generation electronics based on organic nanomaterials, where tuning of electronic interactions can lead to a vast range of new electronic and magnetic phases.

A 2D nanomaterial consisting of organic molecules linked to metal atoms in a specific atomic-scale geometry shows non-trivial electronic and magnetic properties due to strong interactions between its electrons.

A new study, published today, shows the emergence...
