Princeton’s @yibinkang.bsky.social and Yujiao Han led a new study that explains why patients often experience anemia when cancer metastasizes to the bone.

Their ultimate goal?

Uncovering how to slow down bone metastasis.

Anemia in Bone Metastasis Results When Cancer Cells Hijack Iron-Recycling Macrophages

Researchers say findings offer potential therapeutic implications for both bone metastasis and cancer-associated anemia.

Princeton’s commitment to free expression plays out every day across campus — around seminar tables during class and around dining tables at dinner, among the most senior faculty over afternoon tea and incoming students during Orientation, just to name a few.

Civil and respectful dialogue on difficult topics: A bedrock Princeton commitment

Testing arguments and hypotheses yields stronger ideas, and listening to each other fosters deeper community.

Princeton engineers have created a material that can expand, assume new shapes, and follow electromagnetic commands like a remote-controlled robot even though it lacks any gears.

Princeton Engineering - Material? Robot? It's a metabot

The invention is a metamaterial, which is a material engineered to feature new and unusual properties that depend on the material’s physical structure rather than its chemical composition.

Through funding from the NIH, researchers in the Chang Lab have discovered a copper-transport mechanism in the brain that enables advanced stages of sleep, like Rapid Eye Movement (REM) in which dreaming occurs, that is not activated in less complex organisms.

RAD23B acquires a copper metalloadaptor function in amphibian-to-reptile evolution to increase metabolism and regulate genomic integrity

Xiao et al. identified that RAD23B evolves as metalloadaptor in Amniota to regulate copper homeostasis, thus improving cellular metabolism fitness while protecting cell integrity.

🆕 How to value the time of the self-employed

Today on VoxDev, Daniel Agness (University of Maryland), Travis Baseler (University of Rochester), Sylvain Chassang (Princeton University), Pascaline Dupas & Erik Snowberg (The University of Utah) outline research on Kenya: https://ow.ly/BpjO50XaUQs

How to value the time of the self-employed

Valuing the time of the self-employed is crucial for evaluating interventions and conducting cost-benefit analysis. Yet research often misprices this value at zero or equal to market wages. New evidence from Kenya suggests a practical fix: value unpaid self-employed labour at 60% of the local market wage.

🌧️ Research from Princeton and the South China University of Technology shows that climate change and urbanization both play a role in storm-driven rain with the potential to lead to flooding and landslides.

But — the importance of each depends on how close rain is to the city center.

Climate change and urbanization both increase storms’ flooding threat for coastal cities - High Meadows Environmental Institute

City planners defending against future coastal storms will have to contend with increasing rainfall driven by both climate change and urban buildup. But which is the more important factor? New finding...

📣 New preprint! We know humans are biased against AI-creativity. But what about LLMs, now often judging creativity in various contexts? Do they replicate, transform, or amplify this bias? We tested it. Turns out: AI is 2.5X more biased against its own work than humans. arxiv.org/pdf/2510.08831 🧵
