Artistic depiction of the 3D structure of Nipah virus RNA polymerase in the active state. The structure of the Nipah virus RNA polymerase is shown as a transparent surface representation (L protein in green, P protein in orange). The viral RNA, which serves as a template for the RNA polymerase, is shown in blue, the newly produced product RNA in red. The nucleotide substrate is shown in yellow. © Fernanda Sala / UMG

Molecular 3D structure of viral “copying machine” deciphered

Researchers at the University Medical Center Göttingen (UMG) and the Max Planck Institute (MPI) for Multidisciplinary Sciences have shown, for the first time, how the genetic material of the Nipah virus replicates in infected cells. The virus can cause fatal encephalitis in humans. Using cryo-electron microscopy, the team led by

Optimal and fast online change point estimation in linear regression

Authors Hüselitz A, Li H, Munk A Journal Arxiv Citation arXiv:2503.05270. Abstract We consider the problem of sequential estimation of a single change point in a piecewise linear regression model under a Gaussian setup. We demonstrate that a certain CUSUM-type statistic attains the minimax optimal rates for localizing the change

Structural basis of Nipah virus RNA synthesis

Authors Sala FA, Ditter K, Dybkov O, Urlaub H, Hillen HS Journal Nature Communications Citation Nat Commun. 2025 Mar 6;16(1):2261. Abstract Nipah virus (NiV) is a non-segmented negative-strand RNA virus (nsNSV) with high pandemic potential, as it frequently causes zoonotic outbreaks and can be transmitted from human to human. Its

A mouse oocyte extrudes a polar body. This important step in meiosis ensures that the egg cell contains a single set of chromosomes. Chromosomes are stained in magenta, the spindle apparatus that separates the chromosome pairs is shown in green. © Ninadini Sharma / Max Planck Institute for Multidisciplinary Sciences

Why aged oocytes struggle to repair DNA damage

Egg cells need stamina: They are formed in a women’s body before birth and have to be on standby for decades to possibly be fertilized one day. But as they age, they accumulate more and more DNA damage. Until now, it has been unclear why the cell’s repair mechanisms do

Adaptive monotonicity testing in sublinear time

Authors Li H, Liu Z, Munk A Journal Arxiv Citation arXiv:2503.03020. Abstract Modern large-scale data analysis increasingly faces the challenge of achieving computational efficiency as well as statistical accuracy, as classical statistically efficient methods often fall short in the first regard. In the context of testing monotonicity of a regression
