AI Article Synopsis
- The research presents a new method for magneto-optically trapping strontium monofluoride (SrF) molecules, achieving significantly lower temperatures and higher phase space densities than past techniques.
- The trapping process involves rapidly reversing the polarizations of the lasers and the magnetic field, which destabilizes optical dark states crucial for trapping efficiency.
- This approach not only increases the number of trapped molecules and their lifetimes but also allows for the attainment of temperatures as low as 400 μK.
Article Abstract
We demonstrate a scheme for magneto-optically trapping strontium monofluoride (SrF) molecules at temperatures one order of magnitude lower and phase space densities 3 orders of magnitude higher than obtained previously with laser-cooled molecules. In our trap, optical dark states are destabilized by rapidly and synchronously reversing the trapping laser polarizations and the applied magnetic field gradient. The number of molecules and trap lifetime are also significantly improved from previous work by loading the trap with high laser power and then reducing the power for long-term trapping. With this procedure, temperatures as low as 400 μK are achieved.

Previous studies have revealed the essential role of lysosomes in human diseases, including cancer. However, there is a lack of in-depth systematic research on its function in kidney renal clear cell carcinoma (KIRC). In this project, we collected the public dataset of KIRC and selected lysosomal genes tightly linked with survival.

In the present study, we investigated the effects of a representative of the per- and polyfluoroalkyl substance (PFAS) chemical group, namely perfluorooctanoic acid (PFOA), and its alternatives (perfluorobutanoic acid [PFBA] and the hexafluoropropylene oxide dimer acid [GenX]) on bone homeostasis, a process that mainly depends on osteoblast (OB) and osteoclast (OC) activities at the cellular level. C3H10T1/2 cells and bone marrow macrophages (BMMs) were respectively induced into OBs and OCs, and treated with PFOA, PFBA, and GenX at doses of 0.25, 2.

Background: Evidence has revealed that oestrogen deprivation-induced osteolysis is microbiota-dependent and can be treated by probiotics. However, the underlying mechanism require further investigation. This study aims to provide additional evidence supporting the use of probiotics as an adjuvant treatment and to explore the pathophysiology of oestrogen-deprived osteolysis.

Hepatocellular carcinoma (HCC) is the most common form of liver cancer in humans, with an increasing incidence worldwide. The current study aimed to explore the molecular mechanisms that inhibit the proliferation of HepG2 cells, a hepatoblastoma-derived cell line. MSC-derived exosomes (UC-MSCs) were prepared with a median particle size (N50) of 135.

Tandem mass spectrometry (MS) is one of the most effective methods to obtain the structures of organic molecules, enabling the observation of multigenerational ion fragments. Collision-induced dissociation (CID) is currently the most mature technique for mass spectrometry analysis. Ion trap mass spectrometry (ITMS) is favored for on-site detection field, due to its ability of MS analysis with a single trap and its small size.
