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 develop DNA aptamer to detect Alzheimer's biomarkers

With aging populations on the rise, the need for better tools to diagnose and monitor Alzheimer's disease (AD), the most common cause of dementia, has never been more urgent.

Enzyme helps maintain retinal progenitor cells during eye development

The retina is a thin layer of neural tissue at the back of the eye that detects light and converts it into signals, sent to the brain.

Long-read whole genome sequencing uncovers new genetic variants linked to autism

Researchers at the University of California San Diego have identified new genetic variants associated with autism spectrum disorder (ASD) by using long-read whole genome sequencing (LR-WGS), an emerging approach that reads large sections of the genome at once, making it easier for scientists to find new genetic variants and understand how genetic variants affect the function of a gene.

Scientists simulate complete life cycle of a minimal bacterial cell

By simulating the life cycle of a minimal bacterial cell - from DNA replication to protein translation to metabolism and cell division - scientists have opened a new frontier of computer vision into the essential processes of life.

Daily multivitamin intake linked to slower biological aging in older adults

An analysis led by Mass General Brigham investigators found slower aging in older adults after two years of a daily multivitamin, with greater benefits for those who began the trial with accelerated biological age.

FOXJ3 gene identified as the critical link between abnormal brain development and epilepsy

Researchers have discovered that mutations in the FOXJ3 gene act as a "master switch" failure, disrupting how the brain builds its layers and leading to FCD, a primary cause of drug-resistant epilepsy.

Ketone body can strengthen the fitness and antitumor activity of CAR T cells

A naturally occurring byproduct of liver metabolism–the ketone body, β-hydroxybutyrate (BHB)–can strengthen the fitness and antitumor activity of CAR T cells.

New optovolution technique uses light to guide protein evolution

Evolution is biology's powerful method of engineering. It works by generating many variants of DNA, RNA, and proteins inside cells and letting nature "select" the organism that performs best.

Research reveals nuclear metabolic fingerprint in human cells

More than two hundred metabolic enzymes, many of which are normally tasked with producing energy in the mitochondria, are also found sitting directly on top of human DNA, according to a study published today in Nature Communications.

DNA nanomachine strategy reverses chemoresistance in small cell lung cancer

Professor Chao Zhang's team at Zhujiang Hospital, Southern Medical University, has developed a novel DNA nanomachine-based drug delivery and release strategy aimed at overcoming chemoresistance in small cell lung cancer (SCLC).

Scientists discover how herpes simplex virus softens cells to multiply faster

Herpes simplex virus partially liquifies the tightly packed, gel-like interior of human cell nuclei to copy itself faster, a new study shows.

MSK uncovers how interacting mutations shield breast cancer

Researchers at Memorial Sloan Kettering Cancer Center (MSK) have made an important discovery about how genetic mutations in breast cancer patients can interact and drive resistance to certain drugs called CDK4/6 inhibitors. This finding, published in Nature, suggests a new strategy for predicting and preventing resistance to specific therapies based on the tumor's genetic profile.

AI trained on 9 trillion DNA letters predicts harmful mutations and designs new genomes

Scientists developed Evo 2, a large biological foundation model trained on about 9 trillion DNA base pairs that can analyse genomic sequences across bacteria, plants, and humans. The model predicts functional effects of genetic variants and can generate genome-scale DNA sequences, enabling new approaches to studying and designing biological systems.

Researchers find novel path to treat Rett syndrome

A team of researchers at Texas Children's Duncan Neurological Research Institute (NRI) and Baylor College of Medicine report in Science Translational Medicine a potential new approach to treat Rett syndrome – offering early promise for a rare neurodevelopmental disorder that currently has no cure.

MSU scientists map the neural circuitry of drug compulsion

When a cocaine addict relapses, it isn't a matter of personal failure - it's the biological result of their brain's rewiring, new research finds.

New fragmentome technology can detect early liver fibrosis and cirrhosis

Researchers at the Johns Hopkins Kimmel Cancer Center report that an artificial intelligence (AI)-based liquid biopsy test using genome-wide cell-free DNA (cfDNA) fragmentation patterns and repeat landscapes can detect early liver fibrosis and cirrhosis, and may also reveal signals of broader chronic disease burden.

New strategy targets Porphyromonas gingivalis without harming healthy microbes

For years, treating gum disease has meant scraping away plaque, cutting out damaged tissue or turning to antibiotics that kill bacteria indiscriminately.

Study links gut microbiome health directly to ovarian aging processes

A new study details how fecal transplants from older female mice significantly improve ovarian function and fertility in young mice. The surprising results reveal a direct link between the microbiome (the collection of all bacteria and other microbes present) of the gut and ovarian health and function.
