Researchers discover mechanism disrupting CRISPR-Cas9 gene editing
The discovery of CRISPR-Cas9 has made gene editing very easy. Unfortunately, the molecular tool has recently been found to be less precise than previously assumed. It can lead to unwanted mutations in a cell's DNA. Researchers ...

Genes – way weirder than you thought
Pretty much everyone, at least in societies with access to public education or exposure to media in its various forms, has been introduced to the idea of the gene, but "exposure does not equate to understanding" (see Lanie ...

How does plant DNA avoid the ravages of UV radiation?
If the ultraviolet radiation from the sun damages human DNA to cause health problems, does UV radiation also damage plant DNA? The answer is yes, but because plants can't come in from the sun or slather on sunblock, they ...

New mutations in iPS cells are mainly concentrated in non-transcriptional regions
Induced pluripotent stem cells—stem cell-like cells that have been reprogrammed from normal body cells—are a promising avenue of regenerative medicine, and are currently being tested in several clinical studies. However, ...

Low temperature increases risk of DNA damage from UV radiation
Ultraviolet (UV) radiation exposure can cause DNA damage and may be one of the contributing factors in the global amphibian extinction crisis. New research from Prof Craig Franklin and a team of researchers from The University ...

CRISPR-Cas9 breaks genes better if you disrupt DNA repair
CRISPR-Cas9 is the go-to technique for knocking out genes in human cell lines to discover what the genes do, but the efficiency with which it disables genes can vary immensely.

Sequencing method precise enough to reveal mechanisms by which bacteria resist antibiotics
A new technology can read the order (sequence) of the "letters" making up DNA code with enough accuracy to reveal how bacteria use high-speed evolution to defeat antibiotics. That is the finding of a study led by researchers ...
