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).

Researchers sequence the genome of original penicillin strain

ADHD study reveals genetic differences between African Americans and people of European ancestry

Researchers from Children's Hospital of Philadelphia (CHOP) have shown there may be key genetic differences in the causes of attention-deficit hyperactivity disorder (ADHD) between African Americans and people of European ancestry, which may play an important part in how patients of different ethnic backgrounds respond to treatments for this condition. The findings were published online by the journal Scientific Reports.

Scientists uncover new pathway to protect plants from fungal infection

Widespread fungal disease in plants can be controlled with a commercially available chemical that has been primarily used in medicine until now. This discovery was made by scientists from Martin Luther University Halle-Wittenberg (MLU) and the University of the State of Paraná in Brazil.
