The time is now to use the tools we have to end AIDS in children

open access: yesJournal 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.

A Determination of the Hubble Constant from Cepheid Distances and a Model of the Local Peculiar Velocity Field [PDF]

open access: yes, 2001
We present a measurement of the Hubble Constant based on Cepheid distances to 27 galaxies within 20 Mpc. We take the Cepheid data from published measurements by the Hubble Telescope Key Project on the Distance Scale (H0KP).

Rebound of Respiratory Virus Activity and Seasonality to Pre‐Pandemic Patterns

open access: yesJournal 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.

The Araucaria Project. An improved distance to the Sculptor spiral galaxy NGC 300 from its Cepheid variables

open access: yes, 2004
In a previous paper, we reported on the discovery of more than a hundred new Cepheid variables in the Sculptor Group spiral NGC 300 from wide-field images taken in the B and V photometric bands at ESO/La Silla.

Optical Light Curve of the Type Ia Supernova 1998bu in M96 and the Supernova Calibration of the Hubble Constant [PDF]

open access: yes, 1998
We present the UBVRI light curves of the Type Ia supernova SN 1998bu which appeared in the nearby galaxy M96 (NGC 3368). M96 is a spiral galaxy in the Leo I group which has a Cepheid-based distance.

Synthetic Population of Binary Cepheids. II. The Effect of Companion Light on the Extragalactic Distance Scale

open access: yesThe Astrophysical Journal, 2023
Because of their period–luminosity relation (PLR), classical Cepheids play a key role in the calibration of the extragalactic distance scale and the determination of the Hubble–Lemaître constant H _0 .

Treatment variations in localised prostate cancer in Australia and New Zealand: a registry study

open access: yesBJU International, Volume 136, Issue S2, Page S62-S69, October 2025.
Objective To describe the patterns of care and factors associated with treatment uptake of localised prostate cancer, using the bi‐national Prostate Cancer Outcomes Registry–Australia and New Zealand (PCOR‐ANZ) database. Methods Data for 36 504 patients, diagnosed between 2015 and 2018, from New Zealand and seven Australian jurisdictions were evaluated.
