A prospective analysis of 2,077 children in the Canadian CHILD Cohort Study found that higher intake of ultra-processed foods at age three was associated with slightly higher behavioral and emotional symptom scores by age five. Modeling showed that replacing 10% of calories from ultra-processed foods with minimally processed foods was associated with modestly lower symptom scores.

Scientists developed Evo 2, a large biological foundation model trained on about 9 trillion DNA base pairs that can analyse genomic sequences across bacteria, plants, and humans. The model predicts functional effects of genetic variants and can generate genome-scale DNA sequences, enabling new approaches to studying and designing biological systems.

A perspective in The Journal of Clinical Investigation argues that environmental exposures may interact with the gut microbiome and intestinal barrier to trigger biological processes linked to Parkinson’s disease. The authors propose that cumulative environmental stressors can erode host resilience, promoting α-synuclein pathology, immune activation, and neurodegeneration.

A study from University of Limerick in Ireland has identified the hidden challenges of women living with and managing Gestational Diabetes Mellitus (GDM).

The study is among the first to examine strengths-based indicators of well-being in a large, population-level Indigenous sample.

Accumulation of the protein tau in the brain is one of the hallmarks of Alzheimer's disease. In a paper publishing March 5 in the Cell Press journal Cell Press Blue, researchers report a previously unknown mechanism that appears to enable the build-up of tau.

About one in 20 infants worldwide is subjected to physical abuse by a caregiver in their first two years of life.

Researchers have found that targeted delivery of messenger RNA (mRNA) can restore sperm production and fertility in genetically infertile male mice.

Social memory—the ability to recognize familiar individuals and distinguish them from strangers—is fundamental to social cognition.

Premature ovarian insufficiency (POI) is a clinically significant cause of infertility that affects between 1 to 3% of women of childbearing age.

A comprehensive new systematic review published in The Journal of Nutrition provides the latest evidence that large-scale food fortification is a highly cost-effective intervention for reducing global malnutrition.

Teens who frequently lash out at others may face lasting physical health consequences later in life, according to research published by the American Psychological Association.

Affecting roughly half a million Americans each year, bacterial infections caused by Clostridioides difficile—commonly known as C. diff—are a serious and persistent problem for patients and hospitals alike.

What impact does a viral infection have on our memory, attention, and concentration? The COVID-19 pandemic has reignited interest in this question, which has now been extended to other infections such as HIV, herpes, and hepatitis.

Researchers from the Johns Hopkins Kimmel Cancer Center and The Johns Hopkins University have created a novel database structure that allows investigators anywhere to more easily study multiple types of cancer data - including laboratory results, genetic sequencing and imaging data - in one setting.

Inflammatory osteolysis is a condition involving progressive bone tissue destruction and is observed in many well-known skeletal disorders, including rheumatoid arthritis, osteoporosis, and chronic apical periodontitis.

Current findings reveal no support for emotional benefits from probiotic cosmetics, highlighting the need for further investigation into neurocosmetics.

People who use drugs with anticholinergic effects, including certain antidepressants, drugs for urinary incontinence and common antihistamines, are at higher risk of developing cardiovascular disease.

The study identifies molecular changes in taste receptor cells as a potential cause of persistent taste dysfunction in long COVID-19, impacting quality of life.

A team of Korean researchers has, for the first time in the world, developed a technology capable of enabling early diagnosis of major neurological disorders, including epilepsy, Parkinson's disease, and schizophrenia, using only a small amount of saliva.
