Head and neck squamous cell carcinomas responded better to a combination of two immunotherapies than to one immunotherapy drug, according to a study in Cancer Cell. In addition, an analysis of the tumors after one month of immunotherapy identified which type of immune cells were activated to fight the cancer. These insights could help individualize treatment benefits.

Researchers at Duke University and North Carolina State University have discovered a handful of new CRISPR-Cas systems that could add to the capabilities of the already transformational gene editing and DNA manipulation toolbox. Of the new recruits, one system from bacteria commonly found in dairy cows shows particular promise for human health.
