Scientists at CERN have successfully transported antimatter by road for the first time, moving 92 antiprotons around a 4-kilometre loop on the laboratory's campus near Geneva, Switzerland. The 20-minute journey on a truck marks a key test for a planned antimatter delivery service across Europe. Researchers say this breakthrough will enable more precise experiments on the elusive particles.

Scientists led by Fumihiro Naokawa have developed a new method to measure cosmic birefringence more precisely, a subtle rotation in the polarization of the cosmic microwave background. Their analysis indicates the birefringence angle may exceed the earlier estimate of 0.3 degrees due to phase ambiguity. The findings, published in Physical Review Letters, could aid in probing new physics related to dark matter and dark energy.

Nuclear physicists at the University of Tennessee have made three key findings about the rapid neutron-capture process that forms heavy elements like gold in stellar events. Their research, conducted at CERN's ISOLDE facility, clarifies how unstable atomic nuclei decay. The results, published in Physical Review Letters, could refine models of element formation in the universe.

Scientists at the University of Basel and ETH Zurich have reversed the polarity of a specialized ferromagnet with a focused laser beam, without heating the material. This achievement, detailed in Nature, combines electron interactions, topology, and dynamical control in a single experiment. The method hints at future light-based electronic circuits on chips.

Researchers at New York University have developed a method to direct the assembly of microscopic particles into crystals using light. This technique, detailed in the journal Chem, allows for real-time control over crystal growth and dissolution. The approach could enable new responsive materials for applications in optics and photonics.
