New paper out in PNAS! We show that becoming a grandparent substantially reduces employment and earnings, especially for women. At the same time, grandparents go more to the doctor for respiratory infections, but less for mental health conditions. www.pnas.org/doi/10.1073/...

1/ Research funders cap budgets. They rarely cap the supply of proposals. That is becoming a serious problem. In a new Nature Correspondence, David Bann, Jean-Baptiste Pingault, Matt Keller, Marcus Munafò and I argue that grant funding systems face a tragedy of the commons. rdcu.be/fl0Vv

When does associational language make sense and when does it not? Katrina Kezios and I cover this in "How and when to use causal and associational language" with 3 suggestions for which concepts require causal language and which can be described in associational language.

𝗠𝗼𝗹𝗲𝗰𝘂𝗹𝗮𝗿 𝗘𝗽𝗶𝗱𝗲𝗺𝗶𝗼𝗹𝗼𝗴𝘆 𝗦𝗵𝗼𝗿𝘁 𝗖𝗼𝘂𝗿𝘀𝗲 (𝗨𝗖𝗟, 𝗠𝗮𝘆 𝟮𝟬𝟮𝟲) Molecular genetic data are now widely used in clinical, epidemiological, and population health research. Using them well and interpreting results appropriately requires careful attention to study design, data quality, and population structure.
