Known as PASTE, the technique holds potential for treating a variety of diseases caused by faulty genes.
With the aid of physics and a minuscule magnet, researchers have discovered a new structure of telomeric DNA. Telomeres are sometimes seen as the key to living longer. They protect genes from damage but get a bit shorter each time a cell divides. If they become too short, the cell dies. The new discovery will help us understand ageing and disease.
It has been known for a long time that human brain disorders such as neurological or psychiatric diseases run in families, suggesting some heritability. In line with this hypothesis, genetic risk factors for developing these illnesses have been identified.
Adding seven new letters to DNA’s molecular alphabet and developing a precise readout method enabled Illinois researchers to transform the double helix into a robust, sustainable data storage platform fit for the Information Age.
A discovery of how to build little blocks out of DNA and get them to stick to lipids has implications for biosensing and mRNA vaccines.
Our DNA is very similar to that of the chimpanzee, which in evolutionary terms is our closest living relative. Stem cell researchers at Lund University in Sweden have now found a previously overlooked part of our DNA, so-called non-coded DNA, that appears to contribute to a difference which, despite all our similarities, may explain why our brains work differently. The study is published in the journal Cell Stem Cell.
