A new type of advanced microscope (wide-field coherent multidimensional microscopy) has been developed. It uses a carefully designed sequence of ultrashort light pulses to study the behavior of high-tech materials, with potential practical applications in the study of innovative materials such as those used to build solar panels. This is the result of work by a research group of physicists from the Faculty of Sciences, Mathematics, Physics, and Natural Sciences at Università Cattolica's Brescia campus who, for the first time, have developed a "multidimensional microscope" that, in a sense, records the behavior of materials.
Researchers at South China University of Technology, in collaboration with the Dongguan Institute of Materials Science and Technology, Chinese Academy of Sciences, have developed a novel supranano multi-precipitate microstructure in amorphous soft magnetic composites using Ar/O₂ plasma treatment. By facilitating magnetic-moment reversal, this approach significantly reduced coercivity while maintaining excellent overall performance.

Modern technological breakthroughs like lasers, MRI scanners, semiconductors and quantum computers rest on the study of quantum mechanics. However, the field has predominantly focused on (sub)atomic phenomena far removed from our human senses.
Unconventional superconductors can host unusual electronic states, but understanding what drives their superconductivity becomes difficult when different forms of order coexist. The kagome metal CsV3Sb5 has become a particularly debated example.
Today, many physicists are actively exploring how light could be used to link objects through quantum entanglement. By fully harnessing the effect, they hope to unlock a wide array of applications, from secure communication networks spanning vast distances to sensitive new tests of the fundamental laws of physics.
While lithium has been used as a first-line treatment for the long-term management of bipolar disorder for more than 70 years, scientists still do not fully understand how it produces its therapeutic effects in the brain.In a new study published in PLOS ONE, Surrey researchers used computational chemistry and quantum simulations to investigate whether part of the answer could lie in "nuclear spin"—a quantum property that makes an atom's nucleus behave like a tiny magnet, allowing it to influence nearby electrons and potentially change the outcome of chemical reactions.
Collisions between particles at high energies can sometimes produce new particles and shed light on interactions between the fundamental constituents of matter. Simulating these collisions and their underlying processes could yield valuable insights into how matter behaves at extremely small scales.

According to stellar evolution models, there should be hundreds of millions of black holes floating around in our galaxy. But so far we’ve only found 70. That’s in large part because they are so hard to find, but a citizen science project from the University of Southampton is actively seeking out these hidden monsters with the help of tens of thousands of amateur astronomers through a project on Zooniverse called [Black Hole Hunters](https://www.zooniverse.org/projects/cobalt-lensing/black-hole-hunters).

According to new research, "wandering" black holes may have left an imprint on the Universe as they traveled for billions of years.
In recent decades, astronomers have found evidence that supermassive black holes can really mess with their galaxies' evolution. They gobble up material intended for star formation, quenching the birth of stars. Conversely, jets streaming away from those hungry monsters can also energize gas-rich regions and enhance the chances of a galaxy birthing batches of stars in those areas.
Fine particulate matter (PM2.5) is commonly associated with both health concerns and poor visibility. However, these two effects do not necessarily improve or worsen at the same time.
Four decades after the 1986 nuclear disaster, researchers at Leibniz University Hannover and the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) examined six tiny, highly radioactive fragments that were released from the destroyed reactor in Ukraine in the wake of the incident. Analyses show that these "hot particles" are far more stable than had previously been assumed. The findings could allow for more precise assessments of the health risks posed by such radioactive particles. The paper is published in the Journal of Hazardous Materials.
Smectites are clay minerals that can contain large amounts of structural iron. Unlike iron oxides, they do not dissolve when their iron is reduced, so they can be reduced and reoxidized many times. This makes them a recyclable pool of redox-active iron that supports microbial respiration, transforms contaminants and influences nutrient and trace element cycling.
Creating a quantum device often begins by intentionally damaging a crystal. Scientists fire an ultrafast laser pulse into a material, knocking atoms out of place and leaving behind tiny imperfections called vacancies. Far from being flaws, these vacancies can behave as qubits—the fundamental building blocks of quantum information.
The world would look radically different without rulers and measuring tapes that fit into a pocket. Carpenters, fashion designers and engineers rely on these trusty tools to check the size of everything from a wooden board to a fabric swatch. But physicists who work with light lack that same convenience for one of the basic measurements of their craft. They routinely need to measure and compare the frequencies—colors—of the light waves they are using.
Astronomers have observed the longest-lasting central engine activity ever recorded from a gamma-ray burst. The burst occurred at a redshift of 0.8577, and the activity lasted about 27 days in the burst's own rest frame—around 20 days longer than the previous record. The paper, posted to the arXiv preprint server on Sept. 18, explores different mechanisms that could be powering this puzzling burst.
A research team led by the University of Osaka has directly observed, for the first time, an unusual heavy-fermion state forming at the boundary between a one-atom-thick material and a metal. Such states are closely linked to exotic quantum phenomena, including unconventional superconductivity, and the finding opens new possibilities for designing quantum materials through their interfaces.
Black holes, despite their extreme nature, are described by surprisingly few basic parameters: their mass, charge and spin. Two black holes may have formed for completely different reasons and passed through very different histories, yet still end up in the same final state. John Wheeler summarized this idea with the famous phrase "black holes have no hair."
Trump's chances of winning the Nobel Peace Prize are reportedly low, but experts warn his influence could still shape the 2026 race. Find out who decides the winner.
Physicists at CERN’s Large Hadron Collider have captured the clearest evidence yet that quark-gluon plasma, the scorching-hot matter that filled the newborn universe, behaves like a true liquid. By tracking individual quarks as they blasted through the plasma, researchers saw them leave behind ripples, splashes, and swirling wakes much like a duck moving through water. The finding suggests this primordial “soup” is so dense that it can slow speeding quarks and respond collectively as a fluid.
Francis Halzen is a leader in the study of neutrinos, ghostly particles from across the universe that hint at exciting new physics
STOCKHOLM — Francis Halzen won the Nobel Prize in physics on Tuesday for his efforts to demystify a rare group of neutrinos, tiny cosmic particles that scientists believe offer clues to how the universe evolved. “It was a great surprise and I obviously didn’t expect it,” Halzen said, speaking to the committee by phone from Italy, in a call broadcast at the news conference to announce the winner. Halzen said it was predicted before that he would win the Nobel Prize but the announcement still made him feel “strange.” “I am working on a proposal, and I hope that this prize will help getting it approved,” he said to chuckles from the audience. Halzen paved the way for a new kind of astronomy The Nobel Committee for Physics also said Halzen’s work was instrumental to the construction of the IceCube Neutrino Observatory in Antarctica. “Francis Halzen realized that the ice at the South Pole could visualize these neutrino messengers from cosmos,” committee member Eva Olsson said during the
Karl Deisseroth, Peter Hegemann, and Georg Nagel have been awarded the 2026 Nobel Prize in Physiology or Medicine for their work in developing optogenetics — a technique which makes it possible to show how nerve cells shape memories, feelings, and behaviors in the living brain.

Galactic black holes are cosmic mitochondria, powerhouses of the universe. Most of the energy these supermassive black holes produce comes from the material surrounding them: superheated plasma in their accretion disks interacting with tremendous magnetic fields. But there is a more direct way to extract energy from a black hole. It's known as the Penrose process, and a new study asks whether we could discover a signature of this process.
The universe may be trapped in its own comfort zone, and a researcher in the College of Engineering and Computer Science has helped explain why it cannot seem to leave. A new study suggests the universe could be locked into its current state by the same kinds of quantum effects that scientists study when trying to preserve fragile information inside a quantum computer.
The bulk photovoltaic effect (BPVE), a photoelectric effect that generates photocurrent without a p–n junction, can persist even when a material's average crystal structure remains centrosymmetric, a study from Institute of Science Tokyo has found. Researchers demonstrated this in CuCrP2S6, a van der Waals material that transitions from a noncentrosymmetric to a centrosymmetric average structure. The finding challenges the conventional view of BPVE and suggests a new strategy for enhancing photoelectric conversion.
Even the most chaotic quantum systems keep a permanent mark of their own past—a "quantum birthmark"—that never fades. Researchers from Tampere University, Harvard University and TU Dresden discovered the feature in their recent study. Their findings shed new light on the elusive relationship between classical and quantum mechanics. Looking ahead, these quantum birthmarks, along with related phenomena known as "scars," could eventually be harnessed to power next-generation nanoelectronics.
For more than 70 years, fusion energy researchers have used a particular equation to judge whether a plasma would stay hot and dense enough—for long enough—to reach a point where it could sustain itself without any more external power added. While that equation marks the finish line, also known as ignition, it says nothing about the best way to reach it. New research from the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) maps a path to ignition conditions using far less energy than any other path.
Carbon quantum dots (CQDs) are fluorescent carbon nanomaterials with potential applications in sensing, optoelectronics, displays, anticounterfeiting and environmental technologies. Their optical properties can be adjusted by modifying the carbon structure and surface chemistry, particularly through defect states and the incorporation of heteroatoms. However, achieving predictable and continuous tuning of photoluminescence from a single carbon precursor remains difficult.
Primordial black holes (PBHs) don't exist as far as we know. But if they did, these hypothetical objects would have formed in the early universe rather than from dying stars, and they may even make up dark matter. That's not the end of the weirdness. Their formation could have been even stranger if it occurred in a universe with a dark dimension, which is another theoretical construct. It posits that our space includes a hidden extra spatial dimension.
Supermassive black holes generate tremendous amounts of energy through their accretion disks and jets. But they can also generate energy through the magnetic Penrose process. A new study looks at how we might observe this process through multimessenger astronomy.

Astronomers analyzed 2,435 galaxies hosting actively feeding black holes using data from the Dark Energy Spectroscopic Instrument (DESI). Among them, they identified 546 "bulgeless" galaxies—systems with little or no central stellar bulge. Their paper, published in Monthly Notices of the Royal Astronomical Society, suggests that galaxies without a central bulge grow black holes just as effectively as galaxies that have one—a surprising sign that black holes don't need galaxy mergers to grow normally.
Aerosols are small particles suspended in our atmosphere. They come in many flavors: Wildfire smoke, pollen, desert dust, sea salt lofted by powerful storms, volcanic sulfates and emissions from engines and industrial processes are all examples.
Once called a "pipe dream," quantum computers are now approaching practical use.

While scientists are known for their dedication to their research, crawling on the floor to avoid electrocution for the sake of a measurement seems a little excessive.

Luckily, their efforts led to their receiving the Nobel Prize in 1951.

An instrument built to study cosmic rays has turned out to be a powerful tool for investigating thunderstorms. Earlier observations with the GRAPES-3 muon telescope revealed that thunderclouds can develop electrical potential differences far greater than those ever measured directly. But they also uncovered a puzzle: the instrument detected many more thunderstorm events in the eastern part of its field of view than in the western part. A new study by the same team, published in the Journal of Cosmology and Astroparticle Physics, has now explained why.

Author(s): V. I. LyashukThere is much interest and activity in identifying transuranium isotopes and determining their cosmological origins, such as neutron star mergers. This paper studies how one could determine the production of transuranium isotopes in pulse nucleosynthesis based on isotopic yield ratios, a process that is very dependent on neutron fluence. The relationship between the neutron flux and abundances is determined in a rather unique way: by looking at yields from nuclear tests conducted during the Plowshares program. Making use of these nuclear tests (indicated in the figure) may help determine whether the periodic table has been extended in natural events in space. [Phys. Rev.
