Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have partnered with NTNU, the Norwegian University of Science and Technology in Trondheim, and the Institute of Nuclear Physics in the Polish Academy of Sciences to develop a method that facilitates the manufacture of particularly efficient magnetic nanomaterials in a relatively simple process based on inexpensive raw materials. Using a highly focused ion beam, they imprint magnetic nanostrips consisting of tiny, vertically aligned nanomagnets onto the materials. As the researchers have reported in the journal Advanced Functional Materials (DOI: 10.1002/adfm.202513904), this geometry makes the material highly sensitive to external magnetic fields and current pulses.

In collaboration with scientists in Germany, EPFL researchers have demonstrated that the spiral geometry of tiny, twisted magnetic tubes can be leveraged to transmit data based on quasiparticles called magnons, rather than electrons.

Astronomers combined data from two major gamma-ray observatories with further multi-wavelength information to reveal a “nascent outflow” from the most massive young star cluster in the Milky Way, Westerlund 1.

The observations indicate that charged particles – “cosmic rays” – are accelerated in the vicinity of the star cluster and subsequently transported along the outflow.

The nascent outflow is expected to eventually develop into a channel for the transport of cosmic rays into the Galactic halo – a process widely assumed of great importance for galaxy evolution, but with scarce observational support so far.

Researchers have discovered that not all atoms in a liquid are in motion and that some remain stationary regardless of the temperature, significantly impacting the solidification process, including the formation of an unusual state of matter—a corralled supercooled liquid.  

Helical pulses, shaped like flying electromagnetic conches, long predicted but never directly observed, have now been experimentally realized in both optical and microwave bands. The work shows that light can twist through space and time within a single cycle, forming truly space time nonseparable wave packets. This breakthrough confirms a decades old theoretical prediction and opens new paths for ultrafast communication, topological field control, and advanced imaging.

Listening to the "whispers" of electrons and crystals has lead to a quantum discovery with terahertz light that could help us advance technological innovations and life science research.

Researchers have developed new means of recycling a common pollutant associated with groundwater and agricultural runoff: nitrate.  By developing an electrocatalyst that turns nitrate into ammonia, they have also helped make ammonia production more greener.
