The Astrophysical JournalGlobular clusters contain vast repositories of metal-poor stars that represent some of the oldest stellar generations in the Universe. The archaeological footprint of early Galactic evolution may be retained in the measurable properties of globular ...

Structure of Globular Clusters [PDF]
Highlights of Astronomy, 1998 There was a time, more than a century ago, when Astronomy & Astrophysics was not a European Journal yet, but still an American one. In its Vol. XII, Bailey (1893) published, from photographic observations of two globular clusters (GCs), ω Centauri and 47 Tucanae, what were probably the first extensive star counts, which represent the oldest ...

From omics to AI—mapping the pathogenic pathways in type 2 diabetes
FEBS Letters, EarlyView.Integrating multi‐omics data with AI‐based modelling (unsupervised and supervised machine learning) identify optimal patient clusters, informing AI‐driven accurate risk stratification. Digital twins simulate individual trajectories in real time, guiding precision medicine by matching patients to targeted therapies.

Globular Clusters in the LMC [PDF]
Symposium - International Astronomical Union, 1980 Because globular clusters are the oldest stellar systems, they should be sensitive probes of the early dynamical and chemical evolution of galaxies. Since some success has been achieved in understanding these problems in our own galaxy, it seems appropriate to see what can be learned from the clusters in the Large Magellanic Cloud (LMC).

FEBS Letters, EarlyView.Tuberculosis remains a global health challenge and new therapeutic targets are required. Here, we characterized SseA, a sulfurtransferase from Mycobacterium tuberculosis involved in macrophage infection, and its interaction with the newly identified protein SufEMtb that activates SseA enzymatic activity.

The Astrophysical Journal, 2023 In the context of a project aimed at characterizing the dynamical evolution of old globular clusters in the Large Magellanic Cloud, we have secured deep HST/WFC3 images of the massive cluster NGC 1835.

Molecular Oncology, EarlyView.MET variants in the N‐lobe of the kinase domain, found in hereditary papillary renal cell carcinoma, require ligand stimulation to promote cell transformation, in contrast to other RTK variants. This suggests that HGF expression in the microenvironment is important for tumor growth in such patients. Their sensitivity to MET inhibitors opens the way for

Globular Cluster Counts around 700 Nearby Galaxies
The Astrophysical JournalEmpirically, the total number (or total mass) of globular clusters (GCs) bound in a single galactic system correlates with the virial mass of the system. The form of this relation and its intrinsic scatter are potentially valuable constraints on theories

Keck Imaging of the Globular Cluster Systems in the Early--type Galaxies NGC 1052 and NGC 7332
, 2001 The presence of two globular cluster subpopulations in early-type galaxies is now the norm rather than the exception. Here we present two more examples for which the host galaxy appears to have undergone a recent merger.
