They are key in scientific discoveries that benefit humans, and along with mice, they make up for 95 percent of all laboratory studies. But most of these animal research subjects are "sacrificed" once ...

In neuroscientist Kelly Lambert's lab at the University of Richmond, rats hop into cars, rev their engines, and skid across the floor of an arena. Once they maneuver their vehicles across the finish ...

The tiny blobs of lab-grown human brain tissue were just specks, each measuring a few millimeters in diameter. Researchers at Stanford University made them by cultivating human stem cells into ...

Scientists have discovered a more robust way of grouping chemicals and using read-across for toxicological data to meet regulatory requirements, which could greatly reduce animal testing. The safety ...

Northwestern Engineering researchers have developed the first full, three-dimensional (3D), dynamic simulation of a rat’s complete whisker system, offering rare, realistic insight into how rats obtain ...
