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).

Study shows how a toxin produced by algal blooms in saltwater may cause ALS

Can a computer be used to explain why an environmental toxin might lead to neurodegenerative disease? According to Penn State College of Medicine researchers, a computer generated-simulation allowed them to see how a toxin produced by algal blooms in saltwater might cause Amyotrophic Lateral Sclerosis.

Study shows how the immune system achieves antibody diversity

Diversity is good, especially when it comes to antibodies. It's long been known that a gene assembly process called V(D)J recombination allows our immune system to mix and match bits of genetic code, generating new antibodies to conquer newly encountered threats.

Protein messengers from human microbiome shed light on human health

The human body has been studied for centuries, but there are still mysteries that are yet to unfold. For instance, it was discovered that there are trillions of bacteria living inside the body, those that are beneficial for health. Now, studies are focused on studying the human microbiome and how they affect health and well-being.
