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

Hearing triggered by molecular “spring”

Göttingen research team gains new insights into the sense of hearing   Hearing begins with the stretching of elastic molecular “springs” that open ion channels in the sensory hair cells of the ear. For decades, researchers have known that these gating springs must exist, but they could not find them.

Induced Pluripotent Stem Cell Lines as a Model for Studying the Cellular Phase of Parkinson’s Disease

Authors Abdelrasol H, Outeiro TF Journal Journal of the Society of Medical Sciences of Lisbon Citation JSCMed 2025;169(1). Abstract Parkinson’s disease (PD) is a complex neurodegenerative disorder, characterized by the progressive loss of dopaminergic neurons in substantia nigra pars compacta (SNpc) as a result of intraneural deposition of aggregated alpha-synuclein

The keratin cortex stabilizes cells at high strains

Authors Meyer R, Rölleke U, Schwarz N, Perez-Tirado A, Schepers AV, Janshoff A, Köster S Journal BioRxiv Citation bioRxiv 2025.02.24.639846. Abstract The eukaryotic cytoskeleton consists of three filament types: actin filaments, microtubules and intermediate filaments (IFs). IF proteins are expressed in a cell-type specific manner, and keratins are found in
