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).

New Ultra-Sensitive Platform Quantifies Damaged DNA Fragments

The Korea Research Institute of Standards and Science (KRISS, President Dr. Lee Ho Seong) has developed an ultra-sensitive immunoassay-based analytical platform that can detect and quantify trace amounts of "Small Excised Damaged DNA (sedDNA)" fragments generated during cellular DNA repair.

Gut Microbiota Modulates Tumor Microenvironment Converting Cold Tumors Into Hot

Traditional cancer treatments like chemotherapy and radiotherapy can induce immunogenic cell death (ICD), but their efficacy is often limited by drug resistance, severe off-target toxicity, and immune-related adverse events.

Automated Cell-Free Systems Boost Protein Production Performance Five-Fold

A research team led by Professor Joongoo Lee in the Department of Chemical Engineering at POSTECH (Pohang University of Science and Technology) has developed an automated, modular method for assembling reconstituted cell-free systems, which are test-tube systems that can produce proteins outside living cells.

Using Environmental DNA to Monitor Global Riverine Biodiversity

A global analysis of fish biodiversity using environmental DNA (eDNA) reveals how human activity and climate influence biodiversity patterns in river ecosystems.

Real-Time Molecular Tool Observes Complex Immune System Changes

A lot of things need to go right on a molecular level for immune cells to launch an adaptive response to an infection.

Common Genetic Variant Increases Colorectal Cancer Risks for General Population

A team of scientists from the Barbara Ann Karmanos Cancer Institute, Wayne State University, and institutions across the U.S., have published a landmark paper on the role of TGFBR1*6A, a naturally occurring genetic mutation in the TGFBR1 gene found in approximately 14 percent of the general population.

Scientists Move Beyond Individual Genes to Decode Schizophrenia’s Complex Genetic Network

Scientists have long known that schizophrenia runs in families, but pinpointing exactly which genes contribute to risk has been like searching for needles in a haystack. Now, researchers at the Lieber Institute for Brain Development and a consortium of collaborators from the University of Bari, Italy, and over 60 psychiatric hospitals all over the world, have developed a groundbreaking approach that looks beyond individual genes.

Study Reveals How Arsenic Pollution Alters Bacterial Metabolism and Detoxification

As arsenic levels increased, bacterial richness and diversity declined, while arsenic-tolerant groups such as Proteobacteria became more abundant. The study also found that bacteria strengthened stress-response pathways, including signal transduction and cell motility, and upregulated arsenic-resistance genes such as arsC2 and arsB.

Cryo-EM Imaging Uncovers the Structure of a Mysterious Molecular "Gate"

How large, fully folded proteins can pass through cell membranes without destroying them has long been one of the open questions in cell biology. Using cryo-electron microscopy (cryo‑EM), Leonid Sazanov and Ziyu Zhao at the Institute of Science and Technology Austria (ISTA) have now uncovered new details about a molecular "gate." Their findings were published in Molecular Cell.

New Genetic Discovery Explains Why Colorectal Cancer Spreads so Quickly

Loss of GATA6-a transcription factor that controls which genes are turned on or off-can reprogram colorectal cancer cells into more primitive, adaptable states that can then spread to the liver and establish new tumors, according to Weill Cornell Medicine and Massachusetts Institute of Technology researchers.

Scientists Discover Hidden Brain Development Signaling Pathway

The cytoskeleton gives cells their shape and helps them move. Researchers at Helmholtz Munich and the Ludwig Maximilian University now show that, in neural stem cells, proteins of the cytoskeleton are also found in the cell nucleus, where they can influence developmental programs.

New Research Examines How Blood Cancer Mutations Progress from Healthy States

Researchers have found that a genetic mutation associated with a rare group of blood cancers does not always result in development of the disease. The work provides insight into the initial phases of the disease and may eventually lead to tailored monitoring techniques that improve patient outcomes.

Single-Cell Analysis Uncovers How Cancer Tumors Diversify and Resist Treatment

A comprehensive multi-cancer study from researchers at The University of Texas MD Anderson Cancer Center has revealed that cancer cells within tumors are genetically diverse, yet all carry the same core genetic changes that can be traced back to a common ancestral cell, providing a single-cell view of how tumors adapt, survive and diversify. Understanding this helps explain why some cancer cells manage to survive treatments, paving the way for more tailored diagnostic and therapeutic strategies.
