Protons take to the road

Physicists at CERN have conducted a test run for transporting antimatter out of the lab, aiming to study antimatter in different settings to understand matter-antimatter differences.
According to the Standard Model, the universe should have equal amounts of antimatter and matter, leading to the mystery of why there is more matter today.
The Baryon-Antibaryon Symmetry Experiment at CERN focuses on measuring the magnetic moment of protons and antiprotons to explore matter-antimatter asymmetry.
To enable more precise measurements, a transportable device named BASE-STEP has been developed to carry antiprotons to better-shielded labs.
The BASE-STEP device, tested successfully with protons, aims to transport antiprotons for further experiments with enhanced precision.
The device, mounted on an aluminum frame, uses a Penning trap and superconducting magnet to trap and shield protons from collisions during transport.
The transport system is designed to withstand accelerations and slopes, enabling the safe movement of particles for experiments at other research facilities.
The team plans to transport the device to a new Penning-trap system in Germany to continue studying matter-antimatter symmetry at higher precision levels.
This advancement in transporting antimatter for experiments may provide insights into fundamental physics principles beyond the Standard Model.
The research at CERN's BASE aims to conduct the most precise matter-antimatter symmetry tests in the baryon sector by transporting particles for improved experiments.

Mapping the Mozambique Channel

The Mozambique Channel is home to turbulent waters driven by mesoscale eddies that impact local biodiversity, sediment mixing, and plastic pollution movement.
Scientists measured a mesoscale dipole in the region, which consisted of a large counterclockwise anticyclonic ring and a smaller clockwise cyclonic eddy.
The anticyclonic ring had uniform waters with low chlorophyll, while the cyclonic eddy had high chlorophyll levels and varying salinity, driving vertical motions up to 40 meters per day.
In situ measurements like these aid in understanding energy flows in the ocean, guiding predictions related to nutrient transport, sediment movement, and the impact of climate patterns on the region.

Five-body recombination could cause significant loss from atom traps

Five-body recombination, particularly at specific 'Efimov resonances', could lead to significant loss from ultracold atom traps, as suggested by calculations from US physicists.
These recombination processes, less understood compared to three- and four-body recombination, have implications for molecule construction and nuclear fusion modeling.
When atoms collide in traps, interactions can be either elastic or inelastic, where kinetic and internal energy states are exchanged.
In ultralow-temperature quantum gas studies like Bose-Einstein condensates, three-body collisions caused atom leakage from the condensate.
Vitaly Efimov's work in the 1970s on resonances allowed for the formation of bound states at specific scattering length resonances.
At these resonances, five-body recombination can occur, with four atoms forming a tetramer and a free particle, identified as a principal loss channel in the recent study.
Researchers aim to observe these resonances experimentally using modern laser box traps to manipulate atomic gases.
Understanding five-body recombination can aid in molecule creation and potentially in modeling fusion reactions, like deuterium/tritium fusion.
There are challenges in analyzing larger bound states beyond five, as the scattering length dynamics change with additional particles.
Greene and Higgins' work has drawn acclaim for extending few-body theory to five-particle collisions, with implications for advancing theoretical approaches in this field.
The study is featured in Proceedings of the National Academy of Sciences, sparking interest in the scientific community for its implications on ultracold physics.

Physicists at the Large Hadron Collider turned lead into gold—by accident

Physicists at the Large Hadron Collider in Switzerland accidentally turned lead into gold while smashing lead atoms into each other.
To transform lead into gold, the scientists fired beams of lead nuclei at each other at near-light speeds to create a powerful electric field that pulls out protons.
The lead nuclei, when narrowly missing each other, release protons due to the huge electric field, converting some lead atoms into gold atoms.
The production of gold at the collider is seen as a nuisance as the transformed nuclei collide with the walls, leading to a decrease in beam intensity over time.

This is what an aurora looks like on Mars

The Mars rover Perseverance has captured the first image of an aurora on the surface of another planet, which appeared greenish during a solar storm on 18 March 2024.
Aurorae on Mars are generated when charged particles from the Sun interact with the planet's magnetic field, despite Mars having a weaker magnetic field due to the loss of its internal magnetic dynamo.
Scientists had previously identified different types of aurorae on Mars through data from orbiting spacecraft at ultraviolet wavelengths.
Observations of Martian aurorae were challenging due to the lack of visible-wavelength instruments on rovers, the focus on geological missions, and the fleeting nature of aurorae.
Improvements in aurora forecasting helped researchers time their observations on Perseverance to capture the aurora, which appeared as a diffuse green haze in all directions.
The discovery allows for the study of Martian aurorae variations over time and space, providing insights into particle transport and magnetosphere dynamics.
The researchers emphasize the potential for visible-light instruments to simplify and reduce the cost of future aurora observations on Mars.
Studying Martian aurorae can offer valuable information on the interaction between solar particles, Mars's magnetosphere, and upper atmosphere.
The findings, published in Science Advances, lay the foundation for further research on Mars's aurorae and their implications in understanding planetary magnetospheres.
This groundbreaking observation presents new opportunities to explore auroral phenomena beyond Earth and advance our understanding of planetary magnetospheres.
