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.

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…

The amount of fiber you consume has a huge impact on your overall health. Fiber supports healthy digestion and has been linked to a lower risk of certain cancers, among many other benefits. This increased awareness may help explain why the “fibermax” trend is gaining traction. Fibermaxxing refers to consuming at least the recommended daily amount of fiber for your body weight each day. This idea has gained traction across social and traditional media this year. Jennifer Lee is a scientist at the Gene Mayer USDA Human Nutrition Research Center on Aging at Tufts University. Her research focuses on how…

New research published in Frontiers of human neuroscience suggest that assistive robots may work best when they share control with the user and are at a halfway point between full automation and manual operation. People with severe movement disorders, such as amyotrophic lateral sclerosis (ALS), often require constant assistance from a caregiver with daily tasks such as cooking, eating, and moving objects. Bodily assistive robots have the potential to restore independence, but many existing systems are limited to simple pre-programmed tasks. Brain-robot interfaces, which allow users to control robots using brain signals, offer a promising alternative, but are often noisy,…

Recent public health studies have found a clear link between exposure to common air pollutants and the occurrence of suicidal ideation in adults. This study suggests that chemicals found in everyday products and car exhaust can have a negative impact on human mental health. These results are Affective Disorders Journal. Suicide remains a major public health challenge worldwide. Hundreds of thousands of people die by suicide every year. Suicide rates have continued to rise in the United States over the past decade. Suicidal ideation is a term used to describe thoughts of self-harm or planning one’s own death. Experiencing such…
