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).

Review: Diagnostic radiologists at higher risk of burnout

A review co-authored by Dr. Bradley Spieler, Vice-Chair of Scholarly Activity and Research in the Department of Radiology at LSU Health New Orleans School of Medicine, and Dr. Neil Baum, of Tulane's Department of Urology, reports that although burnout affects more than 50% of health care workers, diagnostic radiologists are at even higher risk.

Neural network 'hallucinates' proteins with new, stable structures

Just as convincing images of cats can be created using artificial intelligence, new proteins can now be made using similar tools. In a report in Nature, a team including researchers at the University of Washington, Rensselaer Polytechnic Institute, and Harvard University describe the development of a neural network that "hallucinates" proteins with new, stable structures.
