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).

Development of mammalian placenta depends upon simple twist of DNA

The development of the mammalian placenta depends upon an unusual twist that separates DNA's classic double helix into a single-stranded form, Yale researchers report July 15 in the journal Nature.

Fewer but larger doses of radiotherapy are safe for patients with early breast cancer

A lower total dose of radiotherapy delivered in fewer but larger doses is as safe in the long term as breast cancer radiotherapy courses giving multiple small doses, according to the final results of a 10-year study.

Human papilloma viruses may play a causal role in prostate cancer

Human papilloma viruses (HPVs) - a common group of viruses known to cause cervical cancers - may also have a causal role in prostate cancer, according to a literature review published in the open access journal Infectious Agents and Cancer, supporting the case for universal HPV vaccination.

Genomics study in Black Americans could lead to precision prostate cancer therapies

Black men in the United States are known to suffer disproportionately from prostate cancer, but few studies have investigated whether genetic differences in prostate tumors could have anything to do with these health disparities.

Study may provide a therapeutically safer strategy for gene editing

The CRISPR gene editing system is a robust tool specifically developed for the targeted editing of genomes. While this tool has considerable therapeutic potential, it is associated with improper editing of “off-target” sites.
