Mobile trap transports 92 antiprotons by road and stores them for over a month in world first

In March 2026, scientists succeeded in transporting antiprotons by road for the first time in a purpose-built trap loaded on a truck. The BASE collaboration, which realized this experiment at the European Organization for Nuclear Research (CERN) in Geneva under the lead of Professor Dr Stefan Ulmer and Dr Christian Smorra from Heinrich Heine University DΓΌsseldorf (HHU), now presents its findings and experiences from this pioneering experiment in the journal Nature. Among other things, they report that it was possible to store antiprotons in a mobile transport vessel for more than a month for the first time ever.

Roll waves emerge as uniform water flow destabilizes on steep slopes, equations show

When it rains, traveling waves appear on steep asphalt pavement, slowly making their way down the slope. Because these so-called "roll waves" propagate without deforming and are typically characterized by abrupt discontinuities, they play an important role in hydraulic engineering. Understanding unsteady flows like roll waves is crucial for the design, management and safety of hydraulic structures such as dam spillway chutes.

Heating mica to 200Β°C reveals friction independent of sliding speed

Through joint research with the U.S. Geological Survey and the University of Tokyo, NIMS for the first time experimentally demonstrated friction completely independent of sliding velocityβ€”an ideal that had never been realizedβ€”by heating mica, a layered oxide also used as a lubricant material, to 200Β°C (392Β°F). NIMS also clarified that this is caused by the disappearance of defects within crystals at high temperatures.

Ultra-cold quantum sensors cut X-ray uncertainty, improving nuclear material assessments

To monitor the amount and type of nuclear material at power plants and weapons facilities, scientists look for a special signalβ€”the unique pattern of gamma rays emitted by specific radioactive elements. However, some of these elements also emit X-rays in the same energy range as the gamma-ray emissions, masking the signal and making nuclear stockpiles harder to assess.

Bound gravitational waves inspired by photonic systems

When one mentions "waves," we immediately think of a perturbation that propagates. This applies to waves on the shore, sound waves in the air or electromagnetic waves that we use to transmit information via optical fibers. The same idea of propagating perturbations applies to gravitational waves (GWs), which entered the mainstream media a decade ago after their first direct detection. These are perturbations of the elastic fabric that we are all embedded in, called spacetime.

Crossing into a mirror world: Particles turn to wisps of fog, and the magnetic monopole paradox dissolves

In Goethe's ballad "ErlkΓΆnig," immortalized in Schubert's fevered 1815 setting, a dying boy riding through the night sees a spectral king beckoning from the darkness. His father calms him: "Mein Sohn, es ist ein Nebelstreif"β€”my son, it is only a wisp of fog. In the poem, the father's reassurance proves tragically wrong. In the quantum world, however, his words acquire an uncanny new meaning.

Electron cooling tames highly charged ions in Penning trap for first time

Researchers at Technical University of Darmstadt and the GSI Helmholtz Center for Heavy Ion Research have succeeded for the first time in decelerating highly charged ions from the GSI accelerator to low energies and subsequently storing them in a Penning trap. They were also successful in performing the first electron cooling of highly charged ions in such a trap. The results have been published in Physical Review X (PRX).

Long-lived ytterbium states could sharpen quantum computing and atomic clocks

Researchers from the University of Amsterdam and the University of New South Wales have answered a question that has been around for decades: whether ions of the metal ytterbium can enter certain long-lived, nearly stable states and, if so, for how long. The measured long-lived states may find applications in quantum computers and atomic clocks.

Magnetic clues inside atomic nuclei help explain how elements form in stars

A scientific team led by Facility for Rare Isotope Beams, or FRIB, has identified the origin of a mysterious excess of low-energy gamma rays emitted by the nucleus zinc-70. They found that the excess is caused by magnetic transitions within the nucleus. The study, "Magnetic Character of the Low-Energy Enhancement in 70Zn," published in Nature, sheds light on a long-standing puzzle in nuclear physics and has far-reaching implications for astrophysics.
