We present a dual isotope magneto-optical trap (MOT), simultaneous sub-Doppler laser cooling, and magnetic trapping of a spin-polarized K-K Bose-Fermi mixture realized in a single-chamber setup with an unenriched potassium dispenser as the source of atoms. We are able to magnetically confine more than 2.2 × 10 fermions ( = 9/2 , = 9/2) and 1.

Chiral ferroelectrics have recently received considerable interest due to their unique chiroptical properties. They can adopt Kleinman symmetry second-harmonic generation (SHG)-active chiral-polar point groups in the ferroelectric phase while Kleinman symmetry SHG-inactive chiral-nonpolar point groups in the paraelectric phase, providing a great opportunity to realize on/off switching of SHG circular dichroism (SHG-CD) response. However, the SHG-CD effect was rarely explored in chiral ferroelectrics, and the on/off switchable SHG-CD has never been reported.

Metabolic rewiring underlies effective macrophages defense to respond disease microenvironment. However, the underlying mechanisms driving metabolic rewiring to enhance macrophage effector functions remain unclear. Here, we demonstrated that the metabolic reprogramming in inflammatory macrophages depended on the acetylation of CLYBL, a citramalyl-CoA lyase, at lysine 154 (K154), and blocking CLYBL-K154 acetylation restricted the release of pro-inflammatory factors.

After spinal cord injury (SCI), reactive astrocytes in the injured area are triggered after spinal cord injury (SCI) and to polarize into A1 astrocytes with a proinflammatory phenotype or A2 astrocytes with an anti-inflammatory phenotype. Monopolar spindle binder 2 (MOB2) induces astrocyte stellation, maintains cell homeostasis, and promotes neurite outgrowth; however, its role in the phenotypic transformation of reactive astrocytes remains unclear. Here, we confirmed for the first time that MOB2 is associated with A1/A2 phenotypic switching in reactive astrocytes following SCI in mice.
