A groundbreaking system promises to greatly accelerate research on the fundamental properties of antimatter.
By achieving lower temperatures of trapped antiprotons, they aim to uncover why the universe favors matter over antimatter, a pivotal question in physics.
Antimatter Research Enhancements
A new technique employing monochromatic light improves the study of internal structures in materials affected by light scattering, enabling detailed observation of particle concentrations.
When driving through a bank of fog, car headlights are only moderately helpful since the light is scattered by the water particles suspended in the air. A similar situation occurs when trying to observe the inside of a drop of milk in water or the internal structure of an opal gem with white light. In these cases, multiple light scattering effects prevent examination of the interior.
Now, a team of researchers at Johannes Gutenberg University Mainz (JGU) and Heinrich Heine University Düsseldorf (HHU) has overcome this challenge and developed a new method to study the interior of a crystalline drop.
At the center of all leading particle physics labs are the particle accelerators that make the research possible. But just why are particle accelerators necessary? What do they do? In this video, Fermilab’s Dr. Don explains it all.

My name is Artem, I’m a graduate student at NYU Center for Neural Science and researcher at Flatiron Institute (Center for Computational Neuroscience).
In this video, we explore the Nobel Prize-winning Hodgkin-Huxley model, the foundational equation of computational neuroscience that reveals how neurons generate electrical signals. We break down the biophysical principles of neural computation, from membrane voltage to ion channels, showing how mathematical equations capture the elegant dance of charged particles that enables information processing.

Recent studies using advanced supercomputing have focused on the dynamics within copper-based superconductors, aiming to develop materials that are efficient at higher temperatures and could improve electronic devices significantly.
Over the past 35 years, scientists have been studying a remarkable class of materials known as superconductors. When cooled to specific temperatures, these materials allow electricity to flow without any resistance.
A research team utilizing the Summit supercomputer has been delving into the behavior of these superconductors, particularly focusing on how negatively charged particles interact with the smallest units of light within the material. This interaction triggers sudden and dramatic changes in the material’s properties and holds the key to understanding how certain copper-based superconductors function.
Researchers have discovered a way to recycle the tiny particles used to create supraparticle lasers, a technology that precisely controls light at a very small scale. The breakthrough could help manage these valuable materials in a more sustainable way.
Supraparticle lasers work by trapping light inside a tiny sphere made of special particles called quantum dots, which can absorb, emit, and amplify light very efficiently.
They are made by mixing quantum dots in a solution that helps them stick together in tiny bubbles. However, not all attempts succeed, and even successful lasers degrade over time. This leads to wasted materials, which can be expensive.
Challenging physics beliefs: Oxford study shows like-charged particles can attract each other over long distances in certain solvents.
Particle physicists have been looking for so-called “sterile neutrinos” for a few decades now. They are a hypothesized particle that would have a tiny mass like the three known neutrinos but would not interact by the weak force or any other Standard Model force, only through gravitational interactions.
Its existence—or their existence—would solve some anomalies seen in neutrino experiments, help answer questions beyond the Standard Model of particle physics, and, if massive enough, could explain cold dark matter or warm dark matter.
But sterile neutrinos have not been seen in any particle experiments, despite many attempts. Now an experiment by the IceCube Collaboration has used 10.7 years of data from their detector near the Amundsen-Scott South Pole Station to lower the probability that at least one sterile neutrino does not exist. Their paper appears in Physical Review Letters.
When water freezes slowly, the location where water turns into ice—known as the freezing front—forms a straight line. Researchers from the University of Twente showed how droplets that interact with such a freezing front cause surprising deformations of this front. These new insights were published in Physical Review Letters and show potential for applications in cryopreservation and food engineering techniques.
When water freezes, it is often thought of as a predictable, solid block forming layer by layer. But what happens if the progressing freezing front encounters tiny particles or droplets? Researchers from the University of Twente have explored this question, discovering that droplets can cause surprising deformations in the way ice forms.
Understanding these cosmic rays allows us to unveil big particle accelerators in the universe that are often associated with the most violent phenomena.
