People who walk more each day tend to score better on several brain tests

Researchers analyzed 14 years of physical activity and blood pressure records from 3,093 US adults and found that higher daily step counts were associated with better performance on tests of attention, cognitive control, and reward-related decision-making. Higher systolic blood pressure was associated with poorer delay-discounting performance, but accounted for only 4.8% of its association with physical activity, while the single cognitive assessment prevented conclusions about causation or cognitive decline.

From turmeric to fenugreek, scientists examine nature’s potential role in diabetes care

A narrative review examined how curcumin, honey, culinary spices, and traditional remedies may influence oxidative stress, inflammation, mitochondrial function, and insulin signaling in diabetes. Although experimental research and some clinical trials suggest potential metabolic benefits, the authors emphasize that larger, well-controlled studies are needed to establish their effectiveness and safety alongside conventional treatments.

Coffee, citrus and genetics: What scientists found inside human breast milk

In a bioRxiv preprint, researchers analyzed 458 metabolites in breast milk samples from 349 mothers to investigate how maternal diet, genetics, clinical characteristics, and milk-cell gene expression relate to milk composition. Maternal diet explained the greatest share of metabolite variation among the measured maternal factors, while specific genetic variants and gene-expression patterns were associated with individual metabolites, although the study did not establish effects on infant health.

Your diet may have more to do with your sense of smell than you think

Researchers analyzed dietary patterns and odor identification in 6,690 adults in Italy, finding that healthier plant-rich diets, particularly those emphasizing fruits and vegetables, were associated with better olfactory function and lower odds of hyposmia. Diets emphasizing less healthy plant foods showed the opposite association, although the cross-sectional study could not establish whether diet influences smell or impaired smell affects food choices.

Cigarette smoke exposure alters ovarian and testicular function in mice

New research has shed light on how exposure to cigarette smoke could affect reproductive health in both men and women, identifying changes in biological processes involved in ovarian function and sperm production.

Researchers uncover how metastatic colorectal cancer evades immune attack

Researchers at Hokkaido University, in collaboration with an international team of scientists led by the University of South Florida Health and Tampa General Hospital, have uncovered an important mechanism behind immune evasion in metastatic colorectal cancer (mCRC).

Nature-based activities may offer lasting relief from loneliness

About one in three Americans and one in six people worldwide feel lonely on a regular basis, a troubling reality that has prompted some public health officials to declare an "epidemic of loneliness."

Disadvantaged children with intellectual disabilities face greater mental health difficulties

Children with intellectual disabilities face greater mental health difficulties when they are from a disadvantaged background, finds a new study led by UCL researchers.

Parents of children with mental health problems face stigma

Parents of children with mental health problems may experience stigma when the ideals that matter most to being considered a "good parent" are perceived as not being met, according to preliminary research led by Weill Cornell Medicine, Columbia University Vagelos College of Physicians and Surgeons and NewYork-Presbyterian investigators.

Improving nurse staffing could ease emergency department crowding

A new study led by researchers from Penn Nursing's Center for Health Outcomes and Policy Research (CHOPR) finds that improving hospital nurse workloads could alleviate delays in care contributing to emergency department crowding.

Researchers improve CRISPR technology for detecting HIV and other RNA viruses

Scientists have long used a powerful gene-editing tool called CRISPR to make precise changes to DNA. But a different version of the technology, known as Cas13a, targets RNA, the genetic material found in viruses such as HIV.

$5.8 million study explores gut-brain inflammation in people with HIV

Oregon Health & Science University researchers have secured a $5.8 million, five-year federal award to investigate whether damage to the gastrointestinal tract contributes to neuroinflammation in people living with HIV - raising the potential for new treatments to preserve brain function in people with HIV and older adults.

Pregnancy reshapes the maternal brain through remarkable neurological changes

For generations, women have been told that the forgetfulness, emotional shifts, sensory changes, and altered sense of self that accompany pregnancy and new motherhood are simply "mommy brain."

CHOP researchers link MAP2K4 variants to a neurodevelopmental disorder

Researchers from Children's Hospital of Philadelphia (CHOP) have discovered the mechanisms of previously unknown changes in a gene that result in symptoms associated with a neurodevelopmental disorder.

Scientists studied diet and lung cancer in 95,612 adults. One eating pattern stood out

A prospective study of 95,612 U.S. adults found that those with the highest sulfur microbial diet scores had a 23% higher adjusted lung cancer incidence hazard and a 19% higher lung cancer-related mortality hazard than those with the lowest scores. However, the associations weakened after accounting for overall dietary quality and competing causes of death, and the findings do not establish a causal relationship.

Doctors avoided two common words when talking about weight with patients

Researchers analyzed 123 recorded primary care consultations involving adults with type 2 diabetes and elevated BMI, finding that weight was discussed in just 39% of visits. Clinicians avoided potentially stigmatizing terms such as "overweight" and "obesity," while weight-related conversations occurred more frequently among patients taking GLP-1 receptor agonists.

Pancreatic cancer cells continuously reshape DNA to evade treatment

A new analysis of nearly half a million cells from dozens of pancreatic tumors, led by researchers at UC San Diego Moores Cancer Center and New York University (NYU), reveals how pancreatic cancer cells continuously reshape their genetic makeup over time, enabling them to evade treatment.

Enhanced CAR T-cell therapy may improve treatment options for patients with B-cell blood cancers

Results from a phase I clinical trial led by The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James) show a possible way to improve therapy options for patients with relapsed or treatment-resistant B-cell blood cancers.

Maternal opioid use in pregnancy linked to childhood hospitalizations

Children whose mothers received opioid prescriptions during pregnancy have a higher rate of hospital admission in childhood than unexposed children, including unexposed siblings, according to a new study published October 13th in the open access journal PLOS Medicine by Dong Keon Yon of Kyung Hee University College of Medicine, South Korea, and colleagues.
