The LIGO-Virgo-KAGRA (LVK) Collaboration has today released its latest catalog of gravitational-wave detections. The data analysed for this update were collected by the twin Laser Interferometer Gravitational-wave Observatory (LIGO) detectors and the Virgo detectors. They are the world’s premier observatory of gravitational waves, ripples in the fabric of spacetime. 

Living systems such as cells rely on membrane pores and channels to transport molecules, exchange signals, and organize biochemical reactions. These functions emerge from dynamic interactions between molecular components. Researchers at the University of Stuttgart have used DNA nanotechnology to develop a synthetic membrane architecture that mimics such interactions. The new platform enables coordinated molecular transport and programmable biochemical reactions inside an artificial compartment. The study was conducted in collaboration with researchers from the University of Michigan and Arizona State University, and has been published in the journal Nature Chemistry. 

The LIGO–Virgo–KAGRA Collaboration published today a new catalog of gravitational wave events. A total of 161 events, detected between April 2024 and the end of January 2025, have been added to the collection, bringing the total number of gravitational wave signals detected to date to 390. Among the most significant findings are: evidence for the existence of second-generation black holes, the most precise sky localization ever achieved for a gravitational wave source, and the first measurement of three vibrational modes of a black hole. A wealth of results that marks the coming of age of gravitational astronomy.

Efficient mixing of dense solid–liquid suspensions is essential across many industries, yet conventional mixing design rules often fail at high particle concentrations. A recent study at Nagoya Institute of Technology challenges traditional mixing methods and shows that placing the impeller near the solid–liquid interface lowers the minimum speed required to keep particles suspended in dense suspensions. These findings offer new strategies for improving energy efficiency and mixing outcomes for high-density suspensions.

Atoms and molecules are the fundamental building blocks of matter. Spectroscopy identifies and quantifies chemical species through the unique spectral fingerprints they imprint on light. Spectroscopy has many applications, ranging from fundamental tests of quantum electrodynamics and investigations of molecular structure to environmental sensing, biomedical diagnostics and industrial monitoring. A highly promising spectroscopic instrument that has the potential to transform the field has emerged over the years: the dual-comb spectrometer. This relies on the interference of two mode-locked ultrafast lasers that produce broad frequency combs composed of evenly spaced narrow spectral lines. In a tutorial article published in Nature Reviews Methods Primers, Nathalie Picqué and Theodor W. Hänsch review the principles, advances and future opportunities of the rapidly developing field of broadband atomic and molecular science using dual-comb spectroscopy.

Researchers have developed a Pt–CuO_x interfacial catalyst that enables near-quantitative conversion of biomass-derived HMF into FDCA at low voltage (0.75 V), significantly reducing energy consumption while achieving 99.1% selectivity and long-term stability.

Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have developed a new procedure, enabling them to speed up elaborate computer simulations that analyze matter under extreme conditions. In particular, this work improves the evaluation of experiments at large-scale research facilities like the European XFEL – and should facilitate substantial progress, among others, in fusion research and laboratory astrophysics. The team is presenting its results in the journal npj Computational Materials (DOI: 10.1038/s41524-026-02088-9).

Lakes play a vital filtering role in the ecosystem: they remove excess nitrogen from the water. An international research team led by the University of Basel and Eawag has now shown that climate change could weaken this natural purification process. This would have consequences extending all the way to coastal marine ecosystems.
