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…
Dr. Rowan Martindale, a paleoecologist and geobiologist at the University of Texas at Austin, was hiking through the Dades Valley in Morocco’s Central High Atlas Mountains when something unusual caught his attention. A research team including Martindale and Aarhus University’s Stefan Bodin were exploring the rugged valley to study the ecology of the ancient coral reef system that existed there when the area was once under the sea. Reaching these reefs required crossing several layers of turbidites, deposits formed by dense underwater debris flows. These deposits often exhibit ripple patterns. However, Martindale noticed that the small bumps and wrinkles superimposed…
An eight-month study of college students found that students who received autonomy support from others tended to have slightly better subjective well-being. They also showed small increases in agreeableness, conscientiousness, and openness to experience. The paper was published in. personality journal. Autonomous support from others refers to interpersonal behaviors that foster an individual’s sense of initiative and psychological freedom, rather than controlling or pressuring them. This is a central concept in a macro-theoretical framework in psychology called self-determination theory. Supporting autonomy involves acknowledging the perspective of others, even if you disagree with it. This includes providing meaningful options rather than…
