Unexpected weight loss can have many causes—but cancer is one you don’t want to miss. This open-access study evaluates whether looking at how blood test results change over time performs better than relying on one abnormal result. Hopeful takeaway: with proper adjustment, trend-based interpretation may improve triage for timely investigation.

What if “aging” looked different depending on sex—and our tools were currently averaging it away? A new study develops sex-specific biological aging clocks across 15 organ systems and finds meaningful differences between female and male trajectories. That could change how risk is measured and how preventive strategies are evaluated—especially for conditions like Alzheimer’s disease and systemic illness.

What if “going digital” only lowers costs when communities have the right foundations already in place? This open-access study examines Medicare spending across US counties with FQHCs and RHCs, using the Digital Health Index. Results suggest higher county digital readiness is associated with lower spending—while short-term increases may not move the needle.

What if some of California’s biggest winter rainstorms start thousands of miles away? This study connects record-breaking precipitation in 2016–2017 and 2022–2023 to early-winter warming over the Tibetan Plateau, even during La Niña years when California is often expected to be drier. By improving how the model “sees” Tibetan Plateau temperatures, the researchers reproduce a large fraction of the observed extreme rainfall.

Why do traits differ across populations—and how do we know when genetics is the driver? In this open-access Nature article, researchers use family relationships in a genetically diverse Mexico City cohort to estimate ancestry effects more cleanly. They find within-family associations for height and type 2 diabetes, and not for educational attainment.

How do we move AI from “interesting results” to day-to-day clinical use? In a large real-world NSCLC study (I³LUNG), researchers tested explainable AI decision support and measured performance across internal testing and external validation. They also explored multimodal models using clinical/blood data, CT, digital pathology, and genomics. See what improved—and what still needs validation:

Why do antibody-secreting cells stick around—and where in the bone marrow do they call home? This study uses a human “bone marrow-on-a-chip” to watch these cells migrate through blood vessels, cluster near survival-supporting regions, and respond to signals like CXCR4–CXCL12. It also shows that the endosteal niche can strongly shape cell movement and retention.
