Separate research teams offered insight this week into how Ras-driven pancreatic cancers develop, and reported that a small molecule targeting mutated K-Ras led to tumor regression in patient-derived xenograft mouse models of K-Ras-driven cancers.
Kinase inhibitors are collectively one of the most successful drug classes, but they are challenging to develop in part because their activity usually depends on their overall effect on multiple different kinases.
Scientists have the first primates born from embryos created via somatic cell nuclear transfer (SCNT), more commonly known as cloning, described in Cell.
According to the World Health Organization's (WHO's) Global tuberculosis report 2017, "TB is the ninth leading cause of death worldwide and the leading cause from a single infectious agent, ranking above HIV/AIDS.

An estimated 10.4 million people fell ill with TB in 2016."
By looking for a combination of DNA and protein biomarkers, a single experimental blood test could detect eight different cancers, and identify the anatomical location of the majority of tumors it detected.
