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 reveals a previously unknown mechanism for DNA folding

A hitherto unknown mechanism for DNA folding is described in a study in Nature published by researchers from Karolinska Institutet and the Max Planck Institute for Biophysics.

Novel imaging method shows link between iron redox and Alzheimer’s disease

There is a growing body of evidence that iron in the brain may play a role in Alzheimer's disease. Lending weight to that idea, a new imaging probe has for the first time shown that in the same regions of the brain where the amyloid beta plaques associated with Alzheimer's occur, there is also an increase in iron redox, meaning the iron in these regions is more reactive in the presence of oxygen.

Environmental exposures during pregnancy can affect obesity risk differently in girls and boys, according to a study

A study published in the journal BMC Medicine describes that the risk of obesity and neurodevelopmental delay can vary between boys and girls concerning certain types of prenatal exposures. The study identifies a combination of four exposure levels that protect girls from developing these complications.
