An unbiased approach for the genome-wide detection of off-target cleavage by CRISPR-Cas9 RNA–guided nucleases reveals wide variability in the off-target activity of different guide RNAs.
Combining four years of field data with computer modeling reveals that development of resistance to Bacillus thuringiensis insecticidal proteins (Bt) in cotton bollworm can be delayed by refuges of non-Bt host plants other than cotton, but that these so-called ‘natural refuges’ are not as effective as non-Bt cotton refuges.
Recent developments in the prosecution of the CRISPR-Cas9 patent in Europe highlight the differences between the intellectual property regimes of Europe and the United States.
