A redditor (Ok_Lingonberry3296) traced $2 billion in nonprofit grants and lobbying records across 45 states to figure out who's behind the age verification bills.

The answer is Meta - a company that profits from your data writing laws that collect more of it.

Excited to share our new preprint on time-lagged F2-statistics, which informs about migration rates from ancient DNA data. Find a preprint here: https://www.biorxiv.org/content/10.64898/2026.03.12.710875v1

The work was driven by Giulio Isacchini and Oskar Hallatschek. Proud to be part of it! Also credit to coauthor and Postdoc @ClemensSchmid for solid support on the ancient DNA analysis and archaeological interpretations!

Inferring Migration Networks with Time-Lagged F2 Statistics

Major demographic events, such as population bottlenecks, founder effects, range expansions, and admixture events, have left lasting imprints on human genetic diversity. Ancient DNA (aDNA) sequencing now makes it increasingly possible to observe these signals across time, opening new avenues to address long-standing questions in human demographic history. Yet, deciphering this genetic archive of demographic history is challenging due to high levels of noise, and the complex ways in which demographic processes shape genetic variation. Here, leveraging the linear time evolution of the expectation of neutral allele frequencies, we develop a method to uncover systematic patterns of gene flow from metapopulation time-series data. We show that directional migration rates can be inferred via linear regression on time-dependent genetic dissimilarity between populations, quantified by an extended F2 statistic evaluated between successive time points. Despite small sample sizes, the method reliably infers migration rates from simulated data by integrating information across multiple time slices. Applied to aDNA sampled from the last 6000 years, we recover signals of well-documented migrations and infer an ancient pan-European migration network. While complementing existing tools that estimate static ancestry proportions, our framework tracks how ancestry is dynamically redistributed through time. ### Competing Interest Statement The authors have declared no competing interest.

Hab ich das jetzt richtig verstanden?

„Aus Angst vor Wärmepumpen, veganem Essen und dem Gendern haben Menschen CDU gewählt.
Jetzt müssen sie lediglich länger arbeiten, müssen mehr für Lebensmittel sowie Heizkosten bezahlen und dürfen nicht mehr krank sein.“

Der positive Trend bei der Berufung von Wissenschaftlerinnen hält an:

Diese Grafik zeigt die Entwicklung bei Direktorinnen, unabhängigen Forschungsgruppenleiterinnen, Gruppenleiterinnen, PostDocs und PhDs in der Max-Planck-Gesellschaft von 2019 bis 2025.

Dennoch bleibt viel Luft nach oben.

Changes over time at the Journal of Applied Ecology "show that editorial diversification is a practical lever for making peer review more inclusive and better aligned with the global distribution of research. These changes make the publication process fairer and improve the quality and global impact of the papers published."
