Researchers map first-ever proteome of healthy human heart

A healthy heart beats about two billion times during a lifetime – thanks to the interplay of more than 10,000 proteins. Researchers from the Max Planck Institute of Biochemistry and the German Heart Centre at the Technical University of Munich have now determined which and how many individual proteins are present in each type of cell that occurs in the heart.

CRISPR shows potential to reduce diseases spread by mosquitoes

Research at the University of California, Riverside, have shown that it is possible for transgenic mosquitos to stably express the Cas9 enzyme in their germline. Cas9 addition will allow the utilization of the CRISPR gene editing tool to carry out efficient and highly targeted changes to the DNA of the mosquitoes.
