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).

Simple technique to choose the sex of offspring by separating X and Y sperm

A simple, reversible chemical treatment can segregate X-bearing sperm from Y-bearing sperm, allowing dramatic alteration of the normal 50/50 male/female offspring ratio, according to a new study by Masayuki Shimada and colleagues at Hiroshima University, published on August 13 in the open-access journal PLOS Biology. The study was performed in mice, but the technique is likely to be widely applicable to other mammals as well.

Study reveals surprising discoveries about poorly understood glioblastoma

Glioblastoma, a cancer that arises in the brain's supporting glial cells, is one of the worst diagnoses a child can receive. The grade IV, highly malignant tumor aggressively infiltrates healthy brain tissue, and most children die of the disease within one to two years of diagnosis, similar to adults.
