Alzheimer’s may begin with a silent drop in brain blood flow

Subtle changes in brain blood flow and oxygen use are closely linked to hallmark signs of Alzheimer’s, including amyloid plaques and memory-related brain shrinkage. Simple, noninvasive scans may one day help spot risk earlier—by looking at the brain’s vascular health, not just its plaques.

The human exposome could change everything we know about disease

Scientists are launching an ambitious global effort to map the “human exposome” — the lifelong mix of environmental and chemical exposures that drive most diseases. Backed by new partnerships with governments, UNESCO, and international science advisory bodies, the initiative is rapidly expanding across continents. Powered by AI and advanced data tools, the movement seeks to shift medicine beyond genetics and toward the real-world factors shaping human health.

New oxygen gel could prevent amputation in diabetic wound patients

Chronic wounds often spiral out of control because oxygen can’t reach the deepest layers of injured tissue. A new gel developed at UC Riverside delivers a continuous flow of oxygen right where it’s needed most, using a tiny battery-powered system. In high-risk mice, wounds healed in weeks instead of worsening. The innovation could dramatically reduce amputations—and may even open doors for lab-grown organs.

Simple blood test can forecast Alzheimer’s years before memory loss

Scientists have created a blood test that can estimate when Alzheimer’s symptoms are likely to begin. By measuring a protein called p-tau217, the model predicts symptom onset within roughly three to four years. The protein mirrors the silent buildup of amyloid and tau in the brain long before memory loss appears. This advance could speed up preventive drug trials and eventually guide personalized care.
