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).

Higher intake of food preservatives linked to increased risk of type 2 diabetes

Higher consumption of food preservatives, widely used in industrially processed foods and beverages to extend their shelf life, has been linked to an increased risk of type 2 diabetes.

New method can help better assess precision genome editing technology

Scientists and physicians can better assess precision genome editing technology using a new method made public today by St. Jude Children's Research Hospital. Significant amounts of time and resources spent improving CRISPR gene editing technology focus on identifying small off-target sites that pose a safety risk, which is also technically challenging.

A mathematical solution for precise control of cellular “noise”

Why does cancer sometimes recur after chemotherapy? Why do some bacteria survive antibiotic treatment? In many cases, the answer appears to lie not in genetic differences, but in biological noise - random fluctuations in molecular activity that occur even among genetically identical cells.

Epigenetic plasticity in germinal center B cells may help explain lymphoma origins

Immune cells called B cells make antibodies that fight off invading bacteria, viruses and other foreign substances. During their preparation for this battle, B cells transiently revert to a more flexible, or plastic, stem-cell-like state in the lymph nodes, according to a new preclinical study from Weill Cornell Medicine investigators.

Researchers explore why Alzheimer's affects men and women differently

More than seven million Americans have Alzheimer's disease, and two-thirds of them are women, according to the Alzheimer's Association. The O'Banion Lab at the Del Monte Institute for Neuroscience at the University of Rochester has long been studying this disease and is looking more closely at the differences between male and female brains.
