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).

Green tea may reduce risk of digestive system cancers among women

Women who drink green tea may lower their risk of developing some digestive system cancers, especially cancers of the stomach/esophagus and colorectum, according to a study led by researchers from Vanderbilt-Ingram Cancer Center.

Scientists create new microparticles that self-assemble like atoms into molecules

Scientists have created new kinds of particles, 1/100th the diameter of a human hair, that spontaneously assemble themselves into structures resembling molecules made from atoms. These new particles come together, or "self-assemble," to form structures in patterns that were previously impossible to make and hold promise for manufacturing advanced optical materials and ceramics.

Eliminating bacteria's DNA, boosting antimicrobial proteins may help prevent recurrent ear infections

Eliminating bacteria's DNA and boosting antimicrobial proteins that already exist may help prevent middle ear infections from reoccurring. These are the findings from a Nationwide Children's Hospital study that examined how an immune defense protein common in the middle ear interacts with a structure meant to protect a colony of bacteria.

Scientists decode epigenetic programming of three virulent forms of acute lymphoblastic leukemia

A team of national and international researchers, led by Weill Cornell Medical College scientists, have decoded the key "software" instructions that drive three of the most virulent forms of acute lymphoblastic leukemia (ALL). They discovered ALL's "software" is encoded with epigenetic marks, chemical modifications of DNA and surrounding proteins, allowing the research team to identify new potential biomarkers and therapeutic targets.
