An enzyme encircles the double helix to repair a broken strand of DNA.

The long and short of CDK12

A new study linking RNA processing to DNA repair may open new avenues to cancer therapy.

MIT engineers have designed a system that can repeatedly measure cancer cells as they flow through an array of mass sensors. Once the cells reach the end, they are collected for RNA-sequencing.

Measuring cancer cell “fitness” reveals drug susceptibility

Together, cell growth rate and gene expression shed light on why some tumor cells survive treatment.

On ancient Mars, water carved channels and transported sediments to form fans and deltas within lake basins. Examination of spectral data acquired from orbit show that some of these sediments have minerals that indicate chemical alteration by water. In the Jezero Crater delta, sediments contain clays and carbonates. (This image combines information from two instruments on NASA's Mars Reconnaissanc...
