The dual-hormone artificial pancreas provides additional reduction in hypoglycemia, offering a promising treatment option for type 1 diabetes patients.
Researchers found that individuals with autism spectrum disorder (ASD) make mixed judgments when presented with neutral facial expressions in photographic images, unlike control group participants. However, the results remained consistent when synthetic images were used, suggesting that it's not the judgment process itself that differs.
A systematic review found no significant difference in the prevalence of verbal abuse between men and women, suggesting that societal factors rather than gender play a role. Men are more at risk due to adopting protective attitudes towards women in female-dominated workplaces.
Research suggests an increase in psychotropic medication prescriptions, with doctors often relying on standardized treatments rather than tailored approaches. The tension between clinical reasoning and the Diagnostic and Statistical Manual of Mental Disorder (DSM) is also a major concern.
A new natural supplement based on medicinal plants and dietary supplements has been developed to relieve canine arthritis. The study found that dogs receiving the treatment showed significant improvements in strength and daily physical activity, with none experiencing a decline in health.

The research contradicts the popular belief that bilingualism at an early age is detrimental to oral and written language learning.
A new study from the University of Montreal found that playing has no goal for children, it's an end in itself, promoting emotional and social well-being. The research highlighted four dimensions of play: play as fun, sedentary games, free time, and risk-taking, which contradict public health's focus on physical activity.
A new molecule, UM171, has been discovered that can multiply stem cells in a unit of cord blood, increasing the number of units available for transplant. This breakthrough could revolutionize the treatment of leukemia and other blood-related diseases, particularly for non-Caucasian patients who often have limited access to transplants.

The researchers developed a predictive model to map the effects of this training on brain function, suggesting potential for improving daily lives.
A Quebec study found that 77% of children placed in out-of-home care eventually reunify with their families, with the majority reuniting within 6 months. Younger children and those from low-socioeconomic backgrounds face a lower likelihood of family reunification.
Researchers developed a new model explaining how autism occurs, with genetically-controlled brain plasticity mechanisms potentially determining autistic capabilities and subtypes. The 'Trigger-Threshold-Target' model suggests focusing on developing children's unique strengths rather than solely correcting behaviors.
Researchers identified three key neurocognitive dimensions: impulsive action, impulsive choice, and reward sensitivity. These dimensions are linked to externalizing problems and can be targeted in interventions. The study suggests prevention and intervention approaches targeting these deficits have potential to impact clinical outcomes.
