DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

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.

Study reveals how immune cells alter vascular plaque formation

A new LMU study shows how differently immune cells influence the formation of dangerous vascular deposits - and identifies miR-147 as a potential starting point for future therapies.

New colorectal cancer screening guidelines emphasize advanced stool tests

With colorectal cancer a growing concern among younger people, the American Cancer Society has endorsed two new types of stool tests to encourage people to get screened while also recommending a limited role for new blood tests many patients find appealing.

Climate change could expand chikungunya into temperate regions worldwide

Chikungunya ('to become contorted' in the Kimakonde language, named after the characteristic joint ache) is classified as one of the neglected tropical diseases by the World Health Organization.

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.

Chronic oral inflammation may impair female fertility and egg quality

Chronic oral inflammation may impair female fertility by triggering a systemic immune response that affects the ovaries.

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.

Sting signaling stimulates vital immune defenses to actively suppress aggressive tumor growth

A new review brings attention to the STING pathway as a critical regulator in both colitis and colon cancer, highlighting its complex and often opposing roles in inflammation and tumor development. The findings underscore how this key component of the innate immune system can act as both a driver of disease and a protective mechanism, depending on biological context.

New AI model detects hidden antibiotic resistance genes beyond standard databases

resLens uses genomic language models to detect antibiotic resistance genes from DNA sequences, performing especially well on long-read data and on some ARGs poorly represented in reference databases.

DNA methylation variability may improve precision cancer treatment strategies

A new review article brings attention to the critical role of DNA methylation heterogeneity in shaping the tumor microenvironment, highlighting its growing importance in understanding cancer progression and advancing more precise treatment strategies.

DNA repair gene variations reveal evolutionary roots of cancer susceptibility

A new review highlights how human evolution has shaped the presence of pathogenic variations in DNA damage repair (DDR) genes, offering a new perspective on why modern populations face increased cancer susceptibility.

Extrachromosomal circular DNA shows promise for precision disease diagnostics

A new scientific focus on extrachromosomal circular DNA (eccDNA) is opening transformative possibilities for disease detection, monitoring, and personalized medicine.

AI-engineered p53 superproteins may reshape future cancer therapies

The Oncodarwinian Hypothesis (OdH) proposes a paradigm shift: cancer is not merely a disease but a potential macro‑immunoadaptive response – a self‑replicating algorithm that can be reprogrammed via AI‑based 3D printed p53 superproteins.

Bioinformatics accelerates discovery of marine-derived bioactive therapeutic peptides

Marine organisms have evolved a remarkable arsenal of host-defense peptides under conditions of extreme variability and constant pathogen exposure. Generally defined as short chains of 2 to 20 amino acid residues, these molecules have become a focal point for biomedicine, food science, and materials science.
