Respiratory viruses awaken dormant breast cancer cells and raise relapse risk

Respiratory viruses such as influenza and COVID-19 can reactivate dormant breast cancer cells in the lungs, raising the risk of metastasis. The process is driven by IL-6–induced cell changes and immune suppression, with the highest recurrence risk soon after infection.

Eating over 60g of almonds a day may protect DNA and cut oxidative damage

A meta-analysis of eight clinical trials found that almond supplementation, especially at doses above 60 g/day, significantly reduced oxidative DNA and lipid damage and improved antioxidant enzyme activity in adults. The benefits varied by biomarker and were influenced by dose, preparation, and participant characteristics.

How moving to a walkable city can add 1,100 steps to your day

Moving to a more walkable city boosts daily step counts by around 1,100, with gains lasting at least three months and consistent across most demographic groups. Large walkability improvements nearly double the share of people meeting U.S. aerobic activity guidelines.

GIPR signaling opens brain’s gate for GLP-1 weight-loss therapy

A Cell Metabolism study reveals that GIPR signaling in oligodendrocytes enhances brain access and weight-loss efficacy of GLP-1R agonists by increasing vascular permeability and targeting appetite-regulating neurons. This mechanism may explain why GIPR/GLP-1R co-agonists outperform single-agent therapies.

Study finds vegetarians less likely to develop several common and rare cancers

A large North American cohort study found that vegetarian diets were linked to lower risks of several cancers, including colorectal, stomach, breast, prostate, and lymphoproliferative cancers. No evidence suggested that vegetarian eating increased cancer risk for any site.

AI voice test could help spot dangerous throat lesions before symptoms appear

Researchers at Oregon Health and Science University found that variability in the harmonic-to-noise ratio (HNR) of speech could help distinguish benign from malignant vocal fold lesions, offering a potential early detection biomarker. The exploratory study used AI to analyze acoustic features from the Bridge2AI-Voice dataset and found differences most pronounced in male participants.

Leg movement variability provides reliable marker of dystonia in pediatric cerebral palsy

Cerebral palsy affects around one in 345 children in the U.S., and more than half of them experience a problem called dystonia - involuntary and often painful muscle contractions, most commonly in the legs, that lead to abnormal movement and postures and make regular activities such as walking difficult.

Cervicovaginal microbiome features predict severe chlamydia infection

A new study has identified markers that may predict whether a chlamydia infection is likely to ascend into the uterus and endometrium.

High-speed 3D imaging microscope captures whole organism dynamics in real time

Researchers have developed a high-speed 3D imaging microscope that can capture detailed cell dynamics of an entire small whole organism at once.

New model links striosomal activity to impaired decision making in psychiatric disorders

Scientists from the Icahn School of Medicine at Mount Sinai, working in collaboration with a team from the University of Texas at El Paso, have developed a novel computational framework for understanding how a region of the brain known as the striatum is involved in the everyday decisions we make and, importantly, how it might factor into impaired decision-making by individuals with psychiatric disorders like post-traumatic stress disorder and substance use disorder.

Sex and residual enzyme activity primarily determine clinical course in Chinese Fabry patients

Fabry disease in mainland China is now mapped through the largest single-centre cohort to date, clarifying how α-galactosidase A deficiency, genotype and sex jointly sculpt the clinical spectrum.

Systems biology identifies sentinel biomarkers bridging ankylosing spondylitis and myocardial infarction

Ankylosing spondylitis (AS) is increasingly recognized as an independent risk factor for premature myocardial infarction (MI), yet the molecular bridge linking chronic axial inflammation to acute coronary events remains poorly mapped.

How circadian biology shapes intestinal regeneration and health

The interplay between the circadian clock, intestinal stem cell niche, and epithelial cell fate is shaping our understanding of how gut homeostasis and cellular regeneration are regulated.

Artificial intelligence enables discovery of novel compounds to fight drug-resistant bacteria

With help from artificial intelligence, MIT researchers have designed novel antibiotics that can combat two hard-to-treat infections: drug-resistant Neisseria gonorrhoeae and multi-drug-resistant Staphylococcus aureus (MRSA).

Scientists decode inner speech from brain activity with high accuracy

Scientists have pinpointed brain activity related to inner speech-the silent monologue in people's heads-and successfully decoded it on command with up to 74% accuracy.

New 2025 guidelines focus on early intervention and lifestyle to manage high blood pressure

Preventing and managing high blood pressure with healthy lifestyle behaviors, such as following a heart-healthy diet including reducing salt intake, staying physically active, maintaining a healthy weight and managing stress—combined with early treatment with medication to lower blood pressure if necessary—are recommended to reduce the risk of heart attack, stroke, heart failure, kidney disease, cognitive decline and dementia, according to a new clinical guideline published today in the American Heart Association's peer-reviewed journals Circulation and Hypertension, and in JACC, the flagship journal of the American College of Cardiology.

Dual epigenetic marks found to regulate cell identity

Shedding light on what determines how cells become what they are meant to be-nerves, bone, muscles, etc.-can also help researchers understand how diseases develop when these biological programs break down.

UC San Diego's ACTRI wins $80 million Clinical and Translational Science Award

The University of California San Diego's Altman Clinical and Translational Research Institute (ACTRI) has received a seven-year, $80 million Clinical and Translational Science Award (CTSA) from the National Center for Advancing Translational Sciences (NCATS), part of the National Institutes of Health.

Mayo Clinic identifies cellular 'fountain of youth' in aging immune systems

The immune system is meant to protect the body from infection and disease. But with age, it can become less capable of doing so.

Microbial DNA signature in the blood differentiates primary liver cancer from metastatic colorectal cancer

Determining whether a cancerous tumor originated in a given location or spread there from another tissue or organ in the body is important when assessing the likely course of a patient's disease.
