UCLA researchers identify brain circuit controlling memory organization

When a person has a new experience, their brain faces a subtle but critical decision: should this experience be categorized with other stored memories, or should it be filed away as its own new memory? Getting it right allows the brain to help people navigate the world.

Blood biomarkers may detect Alzheimer’s risk before symptoms appear

For the first time, researchers found blood biomarkers for Alzheimer's disease that correlated with minor cognitive differences in midlife adults who did not have dementia.

Gut changes linger years after polyp removal and may signal colorectal cancer risk

Researchers found that women who had undergone colorectal adenoma resection still showed gut microbiome and fecal metabolome alterations an average of about 12 years later. These persistent changes partly resembled colorectal cancer-associated patterns, suggesting that the host-microbiome axis may remain altered along the adenoma-cancer continuum.

Tezepelumab reduces steroid dependence in severe asthma patients

New results from the Phase 3 SUNRISE clinical trial show that tezepelumab significantly reduced the need for long-term oral corticosteroid use in adults with severe oral corticosteroid-dependent asthma while maintaining asthma control and improving key clinical outcomes.

Mental health challenges linked to hidden online harms among youth

A new study from researchers at the Child Mind Institute finds that negative online experiences are common among children and adolescents with mental health and neurodevelopmental conditions, and that most incidents are not reported through platform reporting tools.

AI maps how brain fluids move to clear waste

MR-AIV uses physics-informed AI and DCE-MRI scans to infer 3D brain-wide fluid movement in mice without direct flow measurements. The method distinguished slow diffusion-dominated transport from faster advective flow and estimated pressure and permeability patterns linked to brain waste clearance.

Obesity alters tumor environment promoting invasive breast cancer growth

Obesity may change how early-stage breast cancer becomes invasive, according to a study by University of Oklahoma researchers published in The American Journal of Pathology.

Smokers undergoing lung cancer surgery face higher complication risks

Researchers at the University of Cincinnati College of Medicine have found that patients who continue to smoke ahead of lung cancer surgery have a higher risk of pulmonary complications, but their short-term mortality rate is similar to patients who were able to stop smoking before surgery.

AI-powered atlas maps immune structures across multiple cancer types

In a new study published today in Science, researchers from The University of Texas MD Anderson Cancer Center developed a spatial atlas of specialized immune structures, called tertiary lymphoid structures (TLSs), across multiple cancer types.

Low protein intake linked to declining physical function with age

Researchers have found that consuming lower amounts of protein-rich foods may negatively affect physical functioning as people grow older, underscoring the vital function protein plays in preserving mobility and muscle strength in adulthood.

Menstrual pain relief purchases reveal stark income-related healthcare disparities

More than a quarter of women buying menstrual products also purchase pain relief at the same time-and those in lower-income areas are significantly less likely to do so-according to a new study published this week in the open-access journal PLOS Digital Health by Dr. Victoria Sivill of the University of Bristol, UK, and colleagues, which used supermarket loyalty card data to map menstrual pain disparities across England.

Brain transposons may influence aging and neurodegenerative disease progression

Transposable elements (TEs), also called transposons, are DNA sequences capable of moving or replicating from one location to another within a genome.

AI ingredient swaps make meals healthier and more affordable

An artificial intelligence framework that suggests just one to three ingredient swaps can make meals meaningfully more nutritious and less expensive, according to a new study published in the open-access journal PLOS Digital Health by Trevor Chan and Ilias Tagkopoulos of the University of California, Davis, USA.

AI chatbots answer health questions with moderate overall accuracy

Artificial intelligence (AI)-powered chatbots respond to everyday health-related questions from general users with nearly 76% accuracy, which raises concerns about their trustworthiness in real-world client-facing applications, according to a new study led by Penn State researchers.

LSU study examines how restrained sitting limits early childhood movement

Researchers at LSU's Pennington Biomedical Research Center, in collaboration with investigators from 32 countries participating in the SUNRISE International Study, have published new findings examining how restrained sitting contributes to daily movement patterns in early childhood.

Rice and Baylor join BrainGate to develop brain-computer interfaces for people with paralysis

When a person loses a limb, a prosthesis often can help restore a significant degree of mobility. But when movement or communication is impaired by a neurological condition such as amyotrophic lateral sclerosis (ALS), spinal cord injury or stroke, there are, as of yet, very few options for the affected individual.

Mental health diagnostic interviews are less consistent than thought

Diagnostic interviews are widely used by mental health professionals to identify conditions such as anxiety, bipolar disorder and depression in adults, but new research led by McMaster University shows that the long considered "gold standard" may not be as consistent as previously thought.
