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 blood test revolutionizes early cancer detection in Li-Fraumeni Syndrome patients

Canadian researchers develop a cell-free DNA-based multimodal assay for early cancer detection in patients with Li-Fraumeni Syndrome, a high-cancer-risk condition. The assay outperforms conventional methods, promising more sensitive and less invasive cancer surveillance.

Study shows phages can promote mammalian cellular growth and survival

Bacteriophages, also called phages, are viruses that infect and kill bacteria, their natural hosts. But from a macromolecular viewpoint, phages can be viewed as nutritionally enriched packets of nucleotides wrapped in an amino acid shell.

New study challenges long-held belief about how chemotherapy works

A new study from the University of Wisconsin–Madison suggests that chemotherapy may not be reaching its full potential, in part because researchers and doctors have long misunderstood how some of the most common cancer drugs actually ward off tumors.

Boosting brain health with iron and manganese: A dietary defense against cognitive decline

The recent study published in Nutrients explores the link between dietary mineral intake and cognitive impairment in elderly Spanish individuals, finding that increased consumption of iron and manganese significantly reduced cognitive impairment risk in women but showed no effect in men.

Blood test detects cancer earlier in individuals with Li-Fraumeni syndrome

Researchers from The Hospital for Sick Children (SickKids), the Ontario Institute for Cancer Research (OICR) and University Health Network (UHN) have demonstrated that by analyzing patients' blood samples, they are able to detect cancer earlier in individuals with Li-Fraumeni syndrome, an inherited condition with an almost 100 percent life-time risk of developing cancer.
