New Candidate Massive Clusters from 2MASS [PDF]
Massive stars are important for the evolution of the interstellar medium. The detailed study of their properties (such as mass loss, rotation, magnetic fields) is enormously facilitated by samples of these objects in young massive galactic star clusters.

We employed the fast-folding algorithm on L -band globular cluster (GC) observations taken with the Five-hundred-meter Aperture Spherical radio Telescope to search for new pulsars, especially those with a long rotational period.

Variable stars in the globular cluster NGC 2419
We have used DOLORES at the TNG to obtain B,V time series photometry of NGC 2419, one of the most distant and bright clusters in the Galactic halo. These data will be used to study its variable star population in order to check whether the cluster could be the relic of an extragalactic system accreted by the Milky Way.

Isocitrate dehydrogenase 1 (IDH1) mutations are highly recurrent in multiple human cancer types, including cholangiocarcinoma and glioma. IDH1 R132C is the most common IDH1 mutation in cholangiocarcinoma and likely arises from APOBEC3A‐ or APOBEC3B‐mediated deamination.

Ancient Relic Moderately Metal-rich Bulge Cluster Tonantzintla 2
The assembly history of the Galactic bulge is intimately tied to the formation of the proto–Milky Way, yet reconstructing this early phase is difficult because mergers and secular evolution have erased most of its original structure.

This study identifies ARHGAP5, in addition to the frequently mutated ARHGAP35, as significantly mutated in endometrial cancer. Mutations in both genes co‐occur and are associated with their correlated downregulation. Functional CRISPR studies show that both paralogs regulate similar pathways, including actin cytoskeleton organization.

Star Clusters and How to Observe Them
Star clusters are among the most spectacular objects for amateur astronomers to observe and image. They represent the beginning, the present and the future of the universe, from sparse open clusters containing only a dozen stars, to giant globular ...

Searching for Variability in the Blue Straggler Star Region of the Globular Cluster NGC 6397
We studied stellar variability in the subgiant branch and blue straggler stars region of the globular cluster NGC 6397. The aim of this research is to identify and characterize new short-period, low-amplitude variable stars.

Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...

Mass Distribution of Binary Black Hole Mergers from Young and Old Dense Star Clusters
Dense star clusters are thought to contribute significantly to the merger rates of stellar-mass binary black holes (BBHs) detected by the LIGO–Virgo–KAGRA collaboration.
