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 research shows significant variations in B-cells in women with PPD

Jerry Guintivano, PhD, of the University of North Carolina School of Medicine, led an exclusive transcriptome-wide association research that showed substantial changes in B-cells in women with postpartum depression, with pathway observations indicating modified B-cell activation and insulin resistance.

Spatial maps offer insights into the battle between melanoma cells and immune cells

Melanoma is a somewhat unusual cancer-;one that blooms before our very eyes, often on sun-exposed skin, and can quickly become deadly as it turns our own skin against us and spreads to other organs.

Bioprinting bone along with two growth factor encoding genes improves bone repair

Given enough time and energy, the body will heal, but when doctors or engineers intervene, the processes do not always proceed as planned because chemicals that control and facilitate the healing process are missing.

Study advances understanding of gut microbiomes in Alaska's iconic brown bears

A recent study of Alaskan brown bears (Ursus arctos) finds that there is significant variation in the gut microbiome of bear populations, depending on where the bears live.

Single-molecule analysis to study how tetraploid cells replicate DNA from diploid cells

Human cells have two sets of chromosomes (diploid). It is possible, however, that cells have a tetraploid (quadruple) set.

Cryo-EM imaging of STING protein reveals a new binding source for immune attacks

In new research, UT Southwestern scientists report that imaging a key immunity protein known as STING at near-atomic resolution reveals a previously undiscovered binding location that appears to be crucial for launching immunological attacks.

Edinburgh scientists solve century-old evolutionary puzzle about malaria parasites

Scientists have solved a 100-year-old mystery about the evolutionary links between malaria parasites that infect humans and chimpanzees.

Rockefeller scientists reveal how a narrow-spectrum antibiotic selectively targets C. diff

Most antibiotics are double-edged swords. Besides killing the pathogen they are prescribed for, they also decimate beneficial bacteria and change the composition of the gut microbiome.

Researchers discover how an “accordion effect” is vital for switching off genes

In a study that changes the fundamentals of what researchers know about gene silencing, WEHI researchers demonstrated how an “accordion effect” is key to switching off genes.

Transposons are a potential antibiotic resistance, a study reveals

According to biomedical engineers at Duke University, the physical mechanism that enables high doses of antibiotics to encourage the transmission of antibiotic resistance across bacteria is now identified.

Certain RNA molecules may serve as markers of cellular stress in different diseases

The body's ability to respond to various types of stress is essential for maintaining health, and failure of such adaptive stress responses can trigger or worsen numerous diseases.
