New understanding of CRISPR-Cas9 tool could improve gene editing
Of the CRISPR-Cas9 tools created to date, base editors have gotten lots of attention because of their seemingly simple editing: they neatly replace one nucleic acid with another, in many cases all that should be needed to fix a genetic disease. Scientists have now determined the structure of the latest base editor as it swaps out nucleic acids, showing why it can go off target but also how it can be improved.

Smaller habitats worse than expected for biodiversity
Biodiversity's ongoing global decline has prompted policies to protect and restore habitats to minimize animal and plant extinctions. However, biodiversity forecasts used to inform these policies are usually based on assumptions of a simple theoretical model describing how the number of species changes with the amount of habitat. A new study shows that the application of this theoretical model underestimates how many species go locally extinct when habitats are lost.

Study reveals intricate details about Huntington's disease protein
The research focuses on axonal transport -- the way in which vital materials travel along pathways called axons inside nerve cells, or neurons. Scientists found that HTT sometimes journeys along these roadways in cellular vehicles (called vesicles) that also carry freight including a protein called Rab4. The research also identified other materials that may be present in these shipments.

Scientists have now discovered a hypercompact Cas protein, Cas-phi, that should work better. It is half the size of Cas9 and apparently evolved inside a bacteriophage, yet efficiently snips double-stranded DNA.
