Rocky Mountain spotted fever is a serious disease spread by ticks. People can develop fever, headache and a rash a few days after a tick bite. Early diagnosis is critical so treatment can start quickly.
New research produced a faster, simpler test that can detect the bacteria in 40 minutes. The method works in two 20-minute steps at room temperature and does not require complex equipment. A color change shows a positive result.
Doctors often give doxycycline while they wait for confirmatory testing. Researchers hope the new test will reach rural and under-resourced clinics so patients get care sooner.

Gene and blood‑vessel damage add to dementia risk
Researchers studied a genetic variant (APOE ε4) and white matter hyperintensities (WMH), a sign of small blood‑vessel damage. They found both factors raise dementia risk additively, and vascular health may be improved to lower that risk.
