Fewer than 10% of mouse experiments use aged animals, with researchers typically relying on mice that roughly correspond to humans in their early 20s. That gap may help explain why many cancer therapies that...

Scientists found the hidden switch fueling alzheimer’s brain inflammation

The brain has its own built in immune defenses that help detect threats and protect nerve cells. But growing evidence suggests that in Alzheimer's disease, these immune cells become stuck in a state of chronic activation. Instead of helping, they trigger ongoing inflammation that can damage the connections between brain cells. Now, researchers at Scripps Research have identified a molecular...
