Northern Australia wet season (November-April) rainfall exhibits strong variability on multiyear timescales. In order to reveal the underlying mechanisms of this variability, we investigate observational records for the period 1900-2017. At multiyear timescales, the rainfall varies coherently across north-western Australia (NW) and north-eastern Australia (NE), but the variability in these two regions is largely independent. The variability in the NE appears to be primarily controlled by the remote influence of low frequency variations of El Niño-Southern Oscillation (ENSO). In contrast, multiyear variations in the NW appear to be largely driven locally and stem from a combination of rainfall-wind-evaporation feedback, whereby enhanced land-based rainfall is associated with westerly wind anomalies to the west that enhance local evaporation over the ocean to feed the enhanced land based rainfall, and soil moisture-rainfall feedback. Soil-moisture and associated evapotranspiration over northern Australia appear to act as sources of memory for sustaining multiyear wet and dry conditions in the NW. Our results imply that predictability of multiyear rainfall variations over the NW may derive from the initial soil moisture state and its memory, while predictability in the NE will be limited by the predictability of the low frequency variations of ENSO.

Background: Targeted cystic fibrosis (CF) carrier screening panels may lack sensitivity in non-European ancestry groups. This study aims to evaluate the sensitivity of various panels in Australian CF carriers identified through sequencing.
Methods: The following panels were evaluated in 869 CF carriers: Asuragen, Elucigene, Devyser, American College of Medical Genetics and Genomics and Victorian Clinical Genetics Services.
Carbon gain in upper but loss in deeper cropland soils across China over the last four decades.

Increasing soil organic carbon (SOC) in agricultural systems is a primary nature-based option for mitigating climate change, improving soil fertility, and ensuring food security. However, the consequences of global warming and increases in carbon inputs on cropland SOC stocks over the last few decades remain largely unknown, particularly in deeper soil layers. Here, by using repeated measurements, we reassess variations in SOC stocks across a 0 to 100 cm soil profile at the same locations in China's upland croplands in 1980 and 2023.

Background: Juvenile idiopathic arthritis (JIA) is challenging to classify and effectively monitor due to the lack of disease- and subtype-specific biomarkers. A robust molecular signature that tracks with specific JIA features over time is urgently required, and targeted plasma metabolomics may reveal such a signature. The primary aim of this study was to characterise the differences in the plasma metabolome between JIA patients and non-JIA controls and identify specific markers of JIA subtype.

Background: Cancer is one of the leading causes of death in children and adolescents, with a significant concentration in low and middle-income countries. Previous research has identified disparities in cancer incidence and mortality based on a country's level of development. The Middle East and North Africa (MENA) region comprises of countries with heterogeneous income and development levels.
