A University of Houston psychology professor is challenging the notion that dyslexia, or specific reading disorder, stems from a single faulty gene in the brain, suggesting instead that it is caused by an overall brain network vulnerability.

Cardiovascular disease results in around 20 million deaths worldwide and causes around a quarter of all deaths in the UK.

A research team from the Department of Psychiatry at Tohoku University, led by Dr. Zhiqian Yu and Professor Hiroaki Tomita, has uncovered compelling evidence that maternal perinatal depression - psychological distress occurring during pregnancy or postpartum - elevates the risk of autistic-related traits in toddlers, with a particularly strong impact on girls.

Access to paid sick leave among South Korean in-home service workers during COVID-19 was associated with lower perceived infection risk, reduced job stress, and higher job satisfaction. Workers without paid leave reported greater perceived risk and stress, with indirect negative effects on job satisfaction, highlighting paid leave as an important workplace resource.

Health system design plays a major role in medication adherence for chronic diseases, with delivery models influencing access, affordability, and continuity of care. Flexible, well-regulated dispensing systems that address structural barriers can improve long-term treatment outcomes across diverse populations.

Longitudinal data from postmenopausal women suggest that cumulative pregnancy duration and breastfeeding history are associated with modestly better cognitive performance later in life. These associations reflect higher cognitive trajectory levels rather than proven slowing of decline, and causality remains uncertain.

Gene therapy holds the promise of preventing and curing disease by manipulating gene expression within a patient's cells. However, to be effective, the new gene must make it into a cell's nucleus.

Researchers have elucidated key steps in the ubiquitin tagging of the mutated huntingtin protein, providing hope for future therapies.

Parkinson's disease is a progressive neurodegenerative disorder that affects more than one million people in the United States, with approximately 90,000 new cases diagnosed each year.

Alzheimer's disease is often measured in statistics: millions affected worldwide, cases rising sharply, costs climbing into the trillions.

People with ulcerative proctitis, a milder and more limited form of ulcerative colitis, are not at higher risk of developing rectal cancer than the general population.

More than 30 million people with HIV must take antiretroviral therapy (ART) medications daily to keep the virus under control, according to the Joint United Nations Programme on HIV/AIDS (UNAIDS).

Predicting tumor progression is one of the major challenges in oncology. Scientists at the University of Geneva (UNIGE) and the Ludwig Institute for Cancer Research have discovered that neutrophils, a type of immune cell, undergo reprogramming when they come into contact with the tumor ecosystem and contribute to its progression.

A new Canadian study has found that people living with dementia (PLWD) are often excluded from research due to assumptions of incapacity and variations in institutional processes.

Researchers evaluate the effectiveness of a novel extracorporeal total artificial lung system to enable bilateral pneumonectomy in patients with severe ARDS.

New evidence suggests that mpox may be circulating quietly among healthy Nigerians, with some infections occurring without the symptoms that typically trigger detection by health authorities.
