Scientists pave way for ‘nano bots’ to one day diagnose and treat disease. Through a technique known as DNA origami, scientists have created the fastest, most persistent DNA nano motor yet...

A Northwestern University organic chemist and his team now have developed a promising molecular tool that targets and inhibits one of cell immortality’s underlying gears: the enzyme telomerase.

This enzyme is found overexpressed in approximately 90% of human cancer cells and has become an important subject of study for cancer researchers. Normal cells have the gene for telomerase, but it typically is not expressed. “Telomerase is the primary enzyme that allows cancer cells to live forever,” said Karl A. Scheidt, who led the research. “We want to short-circuit this immortality...

Dietary compounds found to influence gut metabolites, buffering stress. Think dietary fiber is just for digestive health? Think again.

Specific fibers known as prebiotics can improve sleep and boost stress resilience by influencing gut bacteria and the potent biologically active molecules, or metabolites, they produce, new University of Colorado Boulder research shows.

The research could ultimately lead to new approaches to treating sleep problems, which affect 70 million Americans.

“The biggest takeaway here is that this type of fiber is not just there to bulk up the stool and pass through the digestive system,” said Robert Thompson, a postdoctoral researcher in the Depa...

COVID-19’s imaging features are variable and nonspecific, but the imaging findings reported thus far do show...
