SuperComputer draws molecular blueprints to repair damaged DNA
The Summit supercomputer revealed how the damaged strands of DNA are surgically repaired by a molecular pathway called nucleotide excision repair (NER). The protein components of the NER can change shape and perform different repair functions on broken strands of DNA (blue and red helix). Credit: Tanmoypole, Georgia State University Sunburn and aging skin are the obvious effects of exposure…

Unique mRNA delivery method could repair defective genes before birth
In utero delivery of Cas9 mRNA/gRNA by ADP-LNP leads to extensive cell editing in the fetal brain. Credit: University of California, Davis New research shows that biomedical tools can successfully deliver genetic material to edit defective genes in developing fetal brain cells. The technology, tested in mice, could halt the progression of genetically based neurodevelopmental conditions such as Angelman syndrome…
