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).

Male age over 45 linked to higher miscarriage risk in IVF with donor eggs

A new international study presented today at the 41st Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE) reveals that IVF cycles involving male partners over the age of 45 carry significantly increased miscarriage risks and lower live birth rates – even when young donor eggs are used.

Ancient DNA sheds light on the origins of leprosy in the Americas

Hansen's Disease, more commonly known as leprosy, is a chronic disease that can lead to physical impairment. Today it exists in over 100 countries, and while the infection is treatable, access to treatment varies widely with socioeconomic conditions.

Urine-based DNA test predicts bladder cancer recurrence after immunotherapy

In a multi-institutional study published in Science Direct, researchers revealed that testing urine-based tumor DNA (utDNA) can help predict which bladder cancer patients are at higher risk for recurrence after treatment.

Ionophore use in farming drives global spread of antibiotic resistance genes, study finds

Researchers identified the widespread presence of the ionophore resistance genes narA and narB in over 2,400 bacterial isolates across 51 countries. These genes are often genetically linked to resistance against critically important human antibiotics, raising concerns over agricultural practices and global antimicrobial resistance.

How 50,000 years of ancestry shaped India’s unique disease patterns

Scientists sequenced the genomes of 2,762 individuals across India, revealing the country’s unique ancestral makeup and a wealth of previously undocumented disease-related gene variants. The study highlights how ancient migrations, founder effects, and endogamy have shaped both diversity and disease risk in India.

Discovery of a genetic dimmer switch controlling embryonic development

A team of scientists at the MRC Laboratory of Medical Sciences (LMS) has uncovered a previously unknown mechanism that controls how genes are switched ‘on’ and ‘off’ during embryonic development.

FAM111B identified as a key driver of glioma progression and therapeutic target

Gliomas are among the deadliest brain tumors, with limited treatment options and poor survival rates. Scientists from China identified FAM111B, a DNA-repair-associated protein, as a key driver of glioma progression.

Investigating the role of ultra-processed foods in the inheritance of autism and ADHD

In a recent publication released by PubMed, American scientist Dr. Renee Dufault at the Food Ingredient and Health Research Institute, provides a peer-reviewed protocol for determining the role ultra-processed foods play in prenatal heavy metal exposures and changes in the expression of the zinc dependent MT-1 (metallothionein) gene that impact child neurodevelopment.

New center in Copenhagen to pioneer the future of protein design

Proteins are the workhorses of biology. They perform virtually every important function in living organisms. They store, copy and protect our DNA, digest food to give us energy, and harness this energy to make our cells and muscles work.

Study explores how a familiar spice tackles the toughest cancer cells

Researchers found that clinically achievable doses of curcumin, the active compound in turmeric, target and suppress colorectal cancer stem-like cells, especially in early adenomas. Curcumin shifts these cells toward differentiation, delays tumor growth in mice, and may offer a safe preventive strategy.

Study reveals how FOXA1 mutations drive prostate cancer and therapy resistance

A new study from the University of Michigan Rogel Health Cancer Center, published in Science, sheds light on how two distinct classes of mutations in the FOXA1 gene-commonly altered in prostate cancer-drive tumor initiation formation and therapeutic resistance.

Study finds overlap between chemotherapy side effects and brain aging

While chemotherapy can be lifesaving, it also damages DNA and leads to cognitive issues known as "chemo brain." These effects resemble the memory and learning problems seen in older adults, prompting University of Oklahoma researchers to investigate this unique overlap of cognitive decline.

Harnessing saliva for precision medicine and early disease diagnosis

A research team led by the University of the Basque Country (Euskal Herriko Unibertsitatea, EHU) has identified hundreds of molecular markers in saliva that could reveal the risk of a person developing major diseases such as cancer, cardiovascular diseases, diabetes and neurodegenerative diseases.
