DNA News and Research

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).

Researchers advocate local data strategies for early cancer detection

Researchers are calling for the application of locally driven strategies, supported by stronger regional evidence, to improve early cancer detection and precise care.

Plague emerged earlier than thought and hit hunter-gatherers hard

Ancient DNA from 46 Lake Baikal hunter-gatherers revealed two early plague outbreak phases about 5,500 years ago, with Yersinia pestis detected in 18 individuals. The findings suggest these basal plague strains caused lethal, child-heavy outbreaks long before dense farming societies, cities, or classical flea-borne bubonic plague emerged.

New human protein atlas maps how cancer rewires the body’s tissues

Researchers created a DIA-MS atlas of 13,609 proteins across 2,856 samples from fetal, healthy adult, paired non-tumor, and tumor tissues. The resource maps tissue-specific protein patterns, cancer-associated changes, organ-specific drug-toxicity signals, and candidate therapeutic targets.

Aging immune cells may explain why autoimmunity rises later in life

A new Review reveals how aging can push the immune system into a paradoxical state, weaker against threats yet more prone to attacking the body’s own tissues.

Psychologist warns DNA testing kits can bring unexpected risks

DNA testing kits are often gifted for Father's Day, Christmas and special occasions. The idea of learning more about yourself and unearthing some long-forgotten family history is certainly appealing for many, but a psychologist has warned that these presents can come with profound psychological implications.

Childhood stress leaves lasting epigenetic marks across the body

The experiences we face early in life may leave their marks on our health in ways that echo across decades-and even across the entire body.

Cancer-driving genetic mutation does not always cause disease

Researchers have found that a genetic mutation associated with a rare group of blood cancers does not always result in development of the disease.

Quest Diagnostics study uncovers widespread community reservoirs of deadly gut bacterium

A common bacterial strain that lives naturally in people's guts can cause a dangerous or deadly infection for some, especially when it becomes multidrug-resistant and causes chronic urinary-tract infections (UTIs) in elderly women.

Epigenetic drugs improve blood vessel health in obesity and diabetes

People with obesity and type 2 diabetes are at high risk of blood vessel damage. This risk depends not only on the genes a person carries, but also on how they are "read".

New biological age tools could reveal health risks before symptoms appear

A JCI review traces biological age measurement from functional tests and blood biomarkers to epigenetic, proteomic, imaging, wearable, and AI-based clocks. It finds that these tools can improve risk prediction beyond chronological age, but standardization, interpretability, and prospective validation are needed before routine clinical use.

Preoperative radiation boosts immunotherapy response in brain metastases

A new study led by researchers at The University of Texas MD Anderson Cancer Center demonstrated that pre-operative radiation therapy for brain metastases not only targets tumor cells directly but also can activate immune pathways that can make tumors more receptive to immunotherapy.

Onion-loving gene linked to lower diabetes and blood pressure risk

Imagine if a doctor could look at your DNA and predict not just your disease risk, but also which foods you're drawn to – and whether those cravings are quietly protecting you.

Men's fertility-friendly underwear may be briefs without benefits

A narrative review found that tight-fitting underwear may modestly raise scrotal temperature and is inconsistently linked to lower sperm production measures. However, current evidence does not show that switching to looser underwear improves real-world fertility outcomes.

Key Alzheimer's protein actively protects neurons from nuclear damage

Researchers at Niigata University's Brain Research Institute have uncovered a new function of amyloid precursor protein (APP), a molecule long studied as the precursor to amyloid-β (Aβ) in Alzheimer's disease (AD).

Autism study reveals shared brain cell changes during early development

Hundreds of genes have been linked to autism, yet the precise molecular and cellular mechanisms behind it remain largely unclear.

Developing brain cells routinely repair severe DNA damage during migration

Newborn nerve cells must squeeze through crowded, narrow spaces-through dense tissue, past other cells, between fibers-to reach the areas where they form neural circuits in the brain cortex.

Prehistoric plague killed hunter gatherers 5,500 years ago

Plague is commonly associated with rats, crowded medieval cities, and the epidemics that swept across Europe during and after the Middle Ages.

Targeted vaccination strategies strengthen global biosecurity and biosafety

Biosafety prevents biohazard risks to humans and the environment, biosecurity protects biological assets from misuse, and One Health is an interdisciplinary framework uniting human, animal, and environmental health—all core to global health protection.

Synthetic biology platform unmasks hidden bacterial targets of bacteriophages

An interdisciplinary team of Rice University researchers has uncovered previously unknown relationships between bacteriophages - viruses that infect bacteria - and their bacterial hosts, offering a powerful new tool for next-generation microbiome engineering.

New study reveals cause of chronic inflammation with age

A new study led by researchers at The University of Texas MD Anderson Cancer Center has uncovered a previously unknown connection between nucleic acid structures called R-loops and age-related inflammation – or inflammaging – that could herald new intervention options for chronic inflammation and the subsequent health conditions.
