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).

Hyperfunction theory offers fresh insights into mechanisms driving human aging

A new research perspective was published in Volume 18 of Aging on July 24, 2026, titled "A brief history of the hyperfunction theory of aging and future directions."

Long-acting HIV prevention tools could help close the gap before a vaccine arrives

A review of non-vaccine HIV interventions highlights the strong preventive effects of long-acting PrEP, sustained ART, U=U, vertical transmission programs, and voluntary medical male circumcision. Gene editing and multispecific antibodies may expand future options, but safety, cost, access, adherence, and implementation barriers remain.

Air pollution may worsen rheumatoid arthritis symptoms and flare risk

A novel study shows that exposure to air pollution, especially fine particulate matter like dust, soot, and smoke (PM2.5), is associated with increased disease activity and flare risk in rheumatoid arthritis (RA).

Mouse study shows how liraglutide briefly rewires gut bacterial communities

Researchers treated male high-fat-fed mice with liraglutide for 14 days, then tracked fecal bacterial communities after a 7-day washout using 16S rRNA sequencing. Liraglutide shifted the microbiome toward Lactobacillus- and Leptogranulimonas-related taxa while reducing several fermentative taxa, but most changes moved back toward baseline after treatment stopped.

Korean study finds no overall childhood cancer link with maternal diabetes

Researchers followed 549,851 Korean children and found no statistically significant association between maternal diabetes and overall childhood cancer. The analysis linked maternal diabetes to an 81% higher relative risk of urinary tract cancer, but the absolute difference was only 37 additional cases per 100,000 offspring.
