Discovery of the Longest-period Classical Cepheid in the Milky Way
The Astrophysical Journal LettersWe report the discovery of the classical Cepheid OGLE-GD-CEP-1884 (= GDS_J1535467-555656) with the longest pulsation period known in our Galaxy. The period of 78.14 days is nearly 10 days longer than that of the previous record-holding Cepheid, S ...

Cepheid and SNIa Distance Scales
, 2001 We first discuss why there remains continuing, strong motivation to investigate Hubble's Constant. Then we review new evidence from an investigation of the Galactic Open Clusters containing Cepheids by Hoyle et al. that the metallicity dependence of the Cepheid P-L relation is stronger than expected. This result is supported by a new analysis of mainly

International Journal of Cancer, Volume 157, Issue 11, Page 2363-2373, 1 December 2025.What's New? Neoadjuvant chemotherapy (NACT) can be highly effective for patients with early‐stage breast cancer. Patients with hormone receptor‐positive (HRpos), HER2‐negative (HER2neg) breast cancer, however, may benefit less from NACT. Here, the authors investigated survival outcomes with adjuvant chemotherapy or NACT in a population of ...

The time is now to use the tools we have to end AIDS in children
Journal of the International AIDS Society, Volume 28, Issue 11, November 2025.Abstract Introduction Progress in reducing and eliminating vertical transmission of HIV in children has stagnated over recent years. Unfortunately, recent decisions in the global donor space are likely to lead to considerably lower funding available for HIV and other disease programmes in high‐burden low‐ and middle‐income settings.

RR Lyrae and Type II Cepheid Variables in Globular Clusters: Optical and Infrared Properties
Universe, 2022 Globular clusters are both primary fossils of galactic evolution and formation and are ideal laboratories for constraining the evolution of low-mass and metal-poor stars.

The Araucaria Project. Near-Infrared Photometry of Cepheid Variables in the Sculptor Galaxy NGC 55
, 2007 We have obtained deep images in the near-infrared J and K filters of four fields in the Sculptor Group spiral galaxy NGC 55 with the ESO VLT and ISAAC camera. For 40 long-period Cepheid variables in these fields which were recently discovered by Pietrzy{\

Rebound of Respiratory Virus Activity and Seasonality to Pre‐Pandemic Patterns
Journal of Medical Virology, Volume 97, Issue 11, November 2025.ABSTRACT The emergence of SARS‐CoV‐2 and the implementation of non‐pharmaceutical interventions (NPIs) profoundly disrupted the transmission dynamics of respiratory viruses, altering their epidemiology and seasonality. However, comprehensive long‐term data on these shifts and their post‐pandemic implications remain limited.
