Artificial intelligence (AI) has the potential not only to redefine the way radiology is practiced, but also to illuminate the unique challenges of radiology, a new study from the National Academy of Sciences finds. Journal of the American College of Radiology (JACR). of JACR Focused Questions on the Impact of AI on Workflow Optimization provides a collection of invited studies and reviews that explore the ways in which AI technologies are regularly utilized across a variety of practice types. When deployed carefully, AI can complement human expertise and improve efficiency and patient care. Successful workflow optimization requires integrating AI…
New research published in Neurology Queen Mary’s University of London has revealed that people of South Asian, African and European ancestry share many genetic risk factors for multiple sclerosis (MS). This new study is one of the most ancestrally diverse genetic analyzes of MS carried out in the UK. MS affects around 150,000 people in the UK and more than 2 million people worldwide, but most genetic research to date has focused on people of Caucasian European ancestry. The research team analyzed genetic data from more than 3,000 people with MS and more than 27,000 people without MS (called controls).…
Childhood obesity has been increasing in recent years. According to the U.S. Centers for Disease Control, in 2024, approximately 1 in 5 U.S. children and teens will meet the clinical definition of obesity. Preventing childhood obesity is not easy. For many years, the main approach has focused on encouraging healthy eating and regular physical activity. Researchers at Yale University now suggest that we should add another important factor to that list: reducing parental stress. A research team led by Yale University psychologist Rajita Sinha has found evidence that reducing parental stress may help reduce the risk of obesity in young…
Major depressive disorder (MDD) is a major global health problem and one of the leading causes of disability. Approximately 30% of people diagnosed with depression develop treatment-resistant depression (TRD). This means that standard antidepressants do not sufficiently improve symptoms. Ketamine has gained attention as a fast-acting antidepressant for TRD patients. However, scientists do not fully understand how this therapy works in the human brain, making it difficult to refine and personalize it. New research published in molecular psychiatry On March 5, 2026, we set out to solve this mystery. The study was led by Professor Takuya Takahashi of the Department…
A large study of U.S. military veterans suggests that GLP-1 diabetes drugs may impact addiction-related outcomes and reveals a surprising association between metabolic treatment and substance use risk. Study: Glucagon-like peptide 1 receptor agonists and risk of substance use disorder in U.S. veterans with type 2 diabetes: A cohort study. Image credit: Kotcha K / Shutterstock In recent research, british medical journal Evidence suggests that commonly prescribed medications for type 2 diabetes (T2D) may be associated with a reduced risk of substance use disorders (SUD). These findings demonstrate an unexpected association between diabetes treatment and addiction risk. Researchers investigated the…
A 12-year national study reveals that aging does not necessarily mean decline. Researchers have shown that many older adults maintain or improve their cognitive and physical abilities, and that positive beliefs about aging are linked to improved long-term health outcomes. Research: Redefining aging: Cognitive and physical improvements through positive age beliefs. Image credit: Finist4 / Shutterstock In a recent study published in the journal geriatricsA group of researchers determined whether older adults can experience improvements in cognitive and physical function over time, and whether positive beliefs about aging predict such improvements. Background: Reconsidering assumptions about declining aging Many people think…
Two-dimensional materials are of intense interest because their electronic and magnetic properties have the potential to power future technologies. Scientists have traditionally treated these two behaviors as separate. Engineers at Illinois Grainger Engineering showed that they are connected by the same underlying mathematics. In a study published in Physical Review Xresearchers at the Granger Institute of Technology at the University of Illinois at Urbana-Champaign have demonstrated how a specially designed two-dimensional magnetic system can follow the same equations that describe mobile electrons in graphene. This mathematical relationship has the potential to impact the design of high-frequency devices and may also…
Scientists reveal how evolution within our own tissues causes disease, protects cells and reveals hidden therapeutic targets for future precision medicine. Somatic cell genomics reveals the consequences of evolutionary competition within tissues that can drive disease, counter monogenic diseases, and protect against common diseases. In a recent study published in the journal cellresearchers reviewed the current evidence on somatic mutations in disease and its potential applications in biomedical discovery. Somatic mutations, genetic changes that occur in cells after conception, are widespread in healthy tissues. Although most mutations are functionally unimportant and do not change the cell’s phenotype, some mutations occur…
A large-scale new multimodal AI system trained on tens of millions of medical images could unify fragmented radiology tools and help doctors interpret scans and generate reports more efficiently. Research: MedVersa: A generalist-based model for diverse medical image processing tasks. Image credit: Thitisan / Shutterstock In a recent study published in the journal NEJM AIresearchers introduced “MedVersa,” a generalist artificial intelligence (AI) model that can capture and interpret a wide range of medical imaging modalities and task types. Unlike traditional AI models trained for specific, narrow tasks, MedVersa is built on tens of millions of medical image instances to detect…
A large British study of more than 165,000 people with dementia found that the drug risperidone was associated with an increased risk of stroke in all patient groups. This finding challenges previous assumptions that certain patients may be safer candidates for medication. Instead, the researchers found no clearly “safe” group. Risperidone is a powerful antipsychotic drug that is often prescribed to dementia patients who experience severe agitation and aggressive behavior. It is commonly used in nursing homes when non-drug approaches cannot control distressing symptoms. However, this study showed that people with dementia who take risperidone have an increased risk of…
