Comprehensive map reveals neuronal dendrites in the mouse brain in greater detail Understanding the shape or morphology of neurons and mapping the tree-like branches via which they receive signals from other cells (i.e., dendrites) is a long-standing objective of neuroscience research. Ultimately, this can help to shed light on how information flows through the brain and pin-point differences associated with specific neurological or psychiatric disorders.

Backup DNA repair system could be cancer's weak spot The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break—when both sides of the DNA helix are cut at once. Healthy cells can normally fix these breaks using highly precise repair systems, but when those systems fail, cells sometimes resort to a less accurate backup method.

KRAS-mutant cancers: Potential target could overcome treatment resistance Researchers at The University of Texas MD Anderson Cancer Center have identified a specific protein, RASH3D19, that is responsible for activation of RAS signaling pathways involved in aggressive tumor growth and resistance to KRAS inhibitors in patients with KRAS-mutant cancers.
