Genome editing procedures optimized

Scientists succeed in boosting the efficiency of CRISPR/Cas9 and related methods and modifying initially inaccessible DNA sequences. They fine-tuned these tools to enable effective genetic screening for modelling specific gene mutations.

New mosquito repellents that work better than DEET

In the age-old battle against mosquitoes, DEET has proven effective at keeping this nemesis at bay, but the repellent is smelly and its protection is short-lived. Now, researchers report that they have designed safe alternatives that have some advantag…
