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).

Lipid pathways driving diabetes and heart disease risk in South Asians

Identifying lipid-linked genetic pathways in Asian Indians offers insights into diabetes and heart disease, crucial for developing ancestry-specific therapies.

Detailed images reveal DNA repair mechanism in cancer-related proteins

Scientists have captured the most detailed structural images to date of a specific type of protein's DNA repair process, a finding that could reveal ways to inhibit the effects of BRCA1 and BRCA2 mutations that heighten the risk for breast, ovarian and other cancers.

Estrogen loss after menopause impacts heart health through gene regulation

Virginia Tech scientists at the Fralin Biomedical Research Institute say the increased risk of cardiovascular disease after menopause may stem not only from declining hormone levels, but also from how those changes influence gene activity.

Newer mail-in stool tests increase colorectal cancer screening completion rates

Colorectal cancer (CRC) is the second most common cause of cancer death in the United States and disproportionally impacts people who receive care in under-resourced settings.

Obesity leaves lasting molecular tags on the immune system

People who live with obesity are 'tagging' a memory of being overweight on a key part of the immune system - leaving people with ongoing risk of obesity-related conditions years after losing weight, according to a 10 year-long study published in EMBO Reports.

New insight into how molecular measures of aging relate to neuroimaging markers of brain health

A new research paper was published in Volume 18 of Aging-US on April 7, 2026, titled "Association of epigenetic age acceleration with MRI biomarkers of aging and Alzheimer's disease neurodegeneration."

Molecular gatekeepers in bacteria prevent the spread of antibiotic resistance

A new study finds that bacteria can actively block the transfer of beneficial genes to neighboring cells, using specialized proteins to specifically destroy shared DNA before it spreads.

Long-term study supports tenofovir alafenamide for chronic hepatitis B

Tenofovir alafenamide (TAF) has demonstrated comparable efficacy to tenofovir disoproxil fumarate (TDF), with improved renal and bone safety, in Chinese participants with chronic hepatitis B enrolled in two Phase 3 trials.

Study identifies epigenetic patterns affecting insulin and glucagon production in type 2 diabetes

Researchers at Lund University in Sweden have carried out the most detailed mapping to date of the epigenome in the cells that regulate the body's blood sugar levels.

Hyperbaric oxygen therapy shows dual effects in glioblastoma treatment

Glioblastoma remains a highly challenging malignancy with a pronounced tendency for recurrence. The hypoxic microenvironment is a key contributor to its therapy resistance.

L-arginine stabilizes protein droplets and prevents harmful fibril formation

Protein droplets serve important biological functions within cells, but in neurodegenerative diseases like Alzheimer's, these liquid-like droplets can form solid-like clumps known as fibrils.

Vitamin D may prevent diabetes in people with certain genes

More than two in five U.S. adults has prediabetes, a condition marked by higher-than-normal blood sugar levels that often leads to type 2 diabetes.

Researchers receive NIH grant to accelerate Alzheimer's drug discovery efforts

Dr. Damian Young, investigator at Texas Children's Duncan Neurological Research Institute (Duncan NRI) and director of the Center for Drug Discovery at Baylor College of Medicine, along with collaborators has been awarded a $6.7 million grant from the National Institute on Aging (NIA), part of the National Institutes of Health (NIH), to develop new approaches to rapidly identify potential treatments for Alzheimer's disease and related dementias with the goal of accelerating the discovery of new therapies.

Restoring gut microbiome may prevent liver cancer in mice

Restoring the gut microbiome to its youthful state may hold the key to slowing aging and preventing liver cancer, one of the fastest-growing cancers worldwide, according to a study to be presented at Digestive Disease Week (DDW) 2026.

Global experts highlight new strategies to target human aging

A new meeting report was published in Volume 18 of Aging-US on April 6, 2026, titled "Toward actionable interventions in human aging (12th ARDD meeting, 2025)."

Study links common herbicide to rising early-onset colorectal cancer risk

Researchers used DNA methylation-based “epigenetic fingerprints” as proxies for lifelong exposome-related patterns and found that early-onset colorectal cancer was associated with lower Mediterranean diet adherence, lower education, smoking-related signatures, and higher picloram-related exposure signals. They then supported the picloram association in nine independent cohorts and with 21 years of US county-level pesticide-use data, while noting that the findings show association rather than proof of causation.

Study reveals genetic factors influencing SYNGAP1 encephalopathy disease severity

SYNGAP1 encephalopathy is a rare genetic disorder for which there is no treatment, causing epilepsy, intellectual disability, psychomotor delay and, frequently, autism.

Breast milk sugars promote beneficial bacterial balance in infant guts

Sugars contained exclusively in breast milk are helping to feed an important balance of bacteria in babies' developing gut microbiomes, a new study has found.

McMaster researchers identify new DNA region linked to frailty

Researchers at McMaster University have identified, for the first time, a novel region of DNA and two associated genes connected to frailty, offering neurological and immune-related insights that might help explain why some older adults are more likely to be frail than others.
