Researchers want to change the way we warn about natural disasters

Uppsala University
Reports and Proceedings

With extreme weather events, fires and floods growing increasingly common, general warnings are no longer adequate. Researchers at Uppsala University, in collaboration with the World Meteorological Organization and others, now call for change – from mass mailings to personalised warnings that actually persuade people to act.

Artificial intelligence predicts success of hip operations

Karlsruher Institut für Technologie (KIT)
Peer-Reviewed Publication

Artificial intelligence can help to predict how well patients with hip osteoarthritis will be able to walk again after an operation. Researchers at Karlsruhe Institute of Technology (KIT) have developed an AI model to analyze movement patterns. This gait biomechanics analysis also enables rehabilitation programs to be tailored to patients’ personal needs. The researchers consider it possible that this approach, developed for the hip joint, could be extended to other joints in the future. They present their results in the journal Arthritis Research & Therapy. (DOI: 10.1186/s13075-025-03709-2)

Peer-Reviewed Publication

Cooperation exists in board games, among researchers and among bacteria. Working closely together locally, scientists have deciphered how two species of bacteria join forces to avoid being eaten.

Major breakthrough in cardiac electrophysiology

Universitat Politècnica de València
Peer-Reviewed Publication

A team from the Universitat Politècnica de València and the company Corify Care has made a major breakthrough in cardiac electrophysiology with the publication of its patented Global Volumetric Mapping technology in the journal Nature Communications Medicine. The publication validates the first system capable of simultaneously mapping all four chambers of the heart, providing physicians with a comprehensive, real-time view of arrhythmias that current solutions cannot offer.

Study creates most precise map yet of agricultural emissions, charts path to reduce hotspots

Cornell University
Peer-Reviewed Publication

To lower agricultural emissions, policymakers and communities first need to pinpoint the sources. Not just by country but crop by crop, field by field. In a Cornell Unviersity study published Feb. 13 in Nature Climate Change, researchers have synthesized data from multiple ground sources and models to map global cropland emissions at high resolution – down to about 10 kilometers – while breaking down emissions by crop and source and identifying regions for more precise mitigation.

Shaping carbon fiber with electricity

Institute of Physical Chemistry of the Polish Academy of Sciences
Peer-Reviewed Publication

Controlled manipulation of the fibers that are as thin as or even thinner than human hair is a real challenge. Despite the technology development, the precise and reversible change of the microfibers' orientation, like the tweezers, is not easy. The interdisciplinary team of researchers from the Institute of Physical Chemistry, Polish Academy of Sciences, has recently developed a way to control the shape of microfibers with electricity. This brings us closer to a novel technical solution in micromechanics and soft robotics. Their recent work, published in the Nature Communications journal, demonstrates the first proof-of-concept results on the motion of pristine carbon fibers caused by asymmetric electrochemical processes occurring in the material.
