Study links uneven PARP inhibitor exposure in ovarian tumors to lysosomal drug “reservoirs”

Researchers say they have identified a cellular mechanism that may help explain why PARP inhibitors can affect tumor cells unevenly: in lab-grown slices of human ovarian tumors, some of these drugs accumulated inside lysosomes, forming slow-release stores that created patchy drug distribution across tissue and even between neighboring cells. The findings were reported in a 2026 paper in Nature Communications.

Oura's chief medical officer, Dr. Ricky Bloomfield, said the company's Symptom Radar feature has prompted the discovery of multiple lymphoma cases by alerting users to vital sign deviations. The tool, originally developed during the COVID-19 pandemic, has also led to early detections of appendicitis and other conditions. Bloomfield highlighted the feature's role in encouraging timely medical consultations.

Smartphone notifications interrupt users' concentration for about seven seconds, according to new research from the University of Lausanne. The effect is stronger for personally relevant alerts, with frequent checks amplifying the distraction. Researchers warn that these brief interruptions accumulate over hundreds of daily pings.

Researchers at Emory University have discovered that excessive brain and muscle activity during minor balance disruptions contributes to poorer balance recovery in older adults, including those with Parkinson's disease. The study, published in eNeuro, reveals that trying harder to balance may actually increase fall risk. Opposing muscles stiffening simultaneously further impairs stability.
