Scientists develop safer CRISPR technique using gentler DNA nicking approach

Researchers at Cornell University have developed a safer and more precise way to study how genes function in living tissues by refining a recently developed CRISPR-based genetic technique in fruit flies, enabling researchers to better study how genes contribute to development and disease.

Can AI help build a fairer food system from farm to plate?

AI could help make food systems more personalized and climate-resilient by linking nutrition, health, farming, logistics, and sustainability data. The review highlights promise in precision nutrition, vertical farming, traceability, and smarter supply chains, while warning that privacy, equity, energy use, data silos, and governance gaps must be addressed.

Extreme trait values often have simpler genetic explanations than thought

Researchers at the Icahn School of Medicine at Mount Sinai have found evidence that people who fall at the extreme high or low ends of certain traits, such as cholesterol, blood glucose, height, and age at menopause, are more likely to have a simple genetic explanation than previously thought.

Prenatal therapy for cystic fibrosis improves lifelong health outcomes

This Cystic Fibrosis Awareness Month, Children's Hospital Colorado (Children's Colorado) is highlighting a growing shift in care: starting cystic fibrosis treatment before birth to improve lifelong health outcomes and reduce hospital stays.

Why blood pressure rises faster in women after midlife

This review examines how sex-specific blood pressure trajectories are shaped by genetics, hormones, metabolic risk factors, lifestyle exposures, environmental stressors, and medical treatments. It highlights that women generally have lower blood pressure earlier in life but may experience steeper increases with aging, especially around and after menopause, with exogenous stressors appearing to have a greater impact in women than in men.

One-time gene editing cuts LDL cholesterol in early hypercholesterolemia trial

A phase 1 NEJM interim analysis found that a single infusion of the investigational base-editing therapy VERVE-102 produced dose-dependent reductions in circulating PCSK9 protein and LDL cholesterol in adults with heterozygous familial hypercholesterolemia or premature coronary artery disease.

Cells detect and silence invading transposons through abnormal RNA signals

Transposons, DNA sequences that can self-replicate and move (jump) throughout the genome, are widespread and can affect cell survival if left unchecked. Cells control these "jumping genes" by silencing them, but little was known about how cells recognize and defend themselves from invading transposons.

Study links fathers’ preconception stress to altered offspring development

Research from the University of Colorado Anschutz suggests that stress experienced by a father before conception may influence an offspring's growth by altering small molecular signals in sperm.

Urine test may help identify autism risk in children

A simple urine test may help identify children at risk for autism sooner than current assessments - opening the door for earlier diagnosis and treatment, and better long-term outcomes for children who do have autism spectrum disorder.

Researchers uncover possible cause of pain in neurofibromatosis type 1

Researchers at Cincinnati Children's have identified a potential new way to relieve chronic pain linked to neurofibromatosis type 1 (NF1), a genetic condition best known for causing tumors to grow along nerves.

Blood proteins can predict multiple sclerosis years before diagnosis

A new study has revealed a group of blood proteins, that are altered in people who go on to develop multiple sclerosis (MS), in some cases more than a decade before diagnosis.

New AI model predicts cancer treatment responses from mutations

Researchers at University of California San Diego have developed a new artificial intelligence (AI) model that can translate a tumor's complex genetic profile into predictions about how that cancer may respond to treatment.

Study links ceramide levels to prostate cancer drug response differences

Ceramides-lipid molecules in cells that affect many physiological functions including cell differentiation, migration, and death-and their metabolites have been implicated in the development of cancer and other conditions.

Researchers identify unique genetic signature in rare oral cancer

Cancer diagnosis can be challenging, and delayed diagnosis can allow cancer to progress, complicating treatment.

Diet and inflammation may play a role in progressive vitiligo

A small case-control study linked higher Dietary Inflammatory Index scores with progressive vitiligo, suggesting that pro-inflammatory dietary patterns may be associated with disease occurrence or progression. The findings support further research into diet, inflammation, and the gut-skin axis as potential targets for vitiligo prevention and management.

DNA metabarcoding reveals hidden freshwater biodiversity in Ontario streams

Researchers using cutting-edge environmental DNA (eDNA) technology have uncovered far greater biodiversity in eastern Ontario waterways than traditional monitoring methods detected over more than a decade, demonstrating the transformative potential of DNA-based biomonitoring for freshwater conservation and environmental management.

Researchers trace the origin of blood cells back to possible single-celled ancestors

Almost all animal species -- including humans -- have blood cells, but between different species our blood tells different stories.

New thermal imaging system detects early melanoma before it is visible

Detecting melanoma before it becomes visible is a major challenge in dermatology. Now, with researchers from Université de Montréal, scientists at Université du Québec's Institut national de la recherche scientifique (INRS) have developed a promising solution.

Senolytic therapy delays early disc degeneration in mouse model

Targeting senescent cells with dasatinib-quercetin preserves disc structure and modulates degeneration-associated pathways in a mouse model.

Small non-coding RNA molecule precisely controls vital gene expression and cellular balance

A rapidly advancing area of biomedical innovation is shining a spotlight on miR-128-3p, a small yet powerful molecule with the potential to reshape how diseases—especially cancer—are detected, monitored, and treated. This microRNA, part of a broader class of non-coding RNAs, plays a critical role in regulating gene activity and maintaining cellular homeostasis.
