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).

From Africa to Eurasia: Genetic insights into human migration and cold adaptation

"Who are we and where do we come from?" This quintessential question has intrigued humanity for millennia.

Modulating gene expression using small molecules

The correct functioning of cells relies heavily on the ability to finely control gene expression, a complex process by which the information contained in DNA is copied into RNA to eventually give rise to all the proteins and most of the regulatory molecules in the cell.

Northwestern researchers propose scalable framework for synthetic biology education

The field of synthetic biology, the science of manipulating biology, has a lot of "cooks in the kitchen," which has both helped it flourish and made it unusually difficult to create a cohesive, consistent curriculum for students at every level of study.

Using liver biopsies to identify predictors of pancreatic cancer metastasis

Researchers at Weill Cornell Medicine with an international team have used liver biopsies to identify cellular and molecular markers that can potentially be used to predict whether and when pancreatic cancer will spread to an individual's liver or elsewhere, such as the lung.

3D-printed chip promises rapid pathogen detection

Every so often, a food product is recalled because of some sort of contamination. For consumers of such products, a recall can trigger doubt in the safety and reliability of what they eat and drink. In many cases, a recall will come too late to keep some people from getting ill.

Cell division's hidden safety mechanism may influence cancer growth

Before a cell commits fully to the process of dividing itself into two new cells, it may ensure the appropriateness of its commitment by staying for many hours-;sometimes more than a day-;in a reversible intermediate state, according to a discovery by researchers at Weill Cornell Medicine. Their revelation of this fundamental feature of biology includes details of its mechanisms and dynamics, which may inform the development of future therapies targeting cancers and other diseases.
