Down syndrome (DS) or trisomy 21 (T21) is present in a significant number of children and adults around the world and is associated with cognitive and medical challenges. Through research, the T21 Research Society (T21RS), established in 2014, unites a worldwide community dedicated to understanding the impact of T21 on biological systems and improving the quality of life of people with DS across the lifespan. T21RS hosts an international conference every two years to support collaboration, dissemination, and information sharing for this goal.

Water electrolysis suffers from electron transfer barriers during oxygen evolution reactions, which are spin-related for magnetic materials. Here, the electron transfer at the Fe_{64}Ni_{36}-FeNiO_{x}H_{y} interface is effectively accelerated when the electrode is heated to trigger the Invar effect in Fe_{64}Ni_{36} Invar alloy, providing more unoccupied orbitals as electron transfer channels without pairing energy. As a result of thermally stimulated changes in electronic states, Fe_{64}Ni_{36}/FeNiO_{x}H_{y} achieved a cascaded oxidation of the catalytic center and water.

Background: Genome-wide association studies (GWAS) in Alzheimer's disease (AD) leveraging endophenotypes beyond case/control diagnosis, such as brain amyloid β pathology, have shown promise in identifying novel variants and understanding their potential functional impact. In this study, we leverage two brain amyloid β pathology measurement modalities, PET imaging and neuropathology, to address sample size limitations and to discover novel genetic drivers of disease.
Method: We conducted a meta-analysis on an amyloid PET imaging GWAS (N = 7,036, 35% amyloid positive, 53.

University of Pittsburgh School of Public Health, Pittsburgh, PA, USA.
Background: Many complex traits and diseases show sex-specific biases in clinical presentation and prevalence. For instance, two-thirds of AD cases are female. Studies suggest that women might have higher cognitive reserve but steeper cognitive decline in older age.

TBI is the leading cause of mortality in young adults and causes a huge socioeconomic burden. Improving outcomes in these patients would be a significant public health benefit.
