A new study by scientists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) shows that when a pressure disturbance moves across an ultrasoft elastic material, such as a gel or a biological tissue, it generates a V-shaped wake that’s strikingly similar to the waves that travel behind a boat.
Quantum computers stand to revolutionize research by helping investigators solve certain problems exponentially faster than with conventional computers. Current quantum computers encounter a challenge where they lose stored information in a process known as quantum scrambling. However, scientists at the University of California, Irvine have discovered a method to enable computers to preserve the data that would otherwise be lost during the scrambling process. The research is published in the journal Physical Review Letters.
An international team of scientists, including researchers from Loughborough University, has developed a method to dramatically speed up the discovery and design of advanced materials. The study, published in Physical Review Letters, shows how the new approach can map complex phase diagrams in as little as a day—rather than weeks or months—and pinpoint where important structures, including crystals and quasicrystals, are likely to form.
“This incident is a stark reminder of the dangers our deputies face during everyday tasks that most people might consider routine,” the Collier County Sheriff’s Office stated
The moon is Earth’s only natural satellite, a rocky celestial body that orbits our planet at an average distance of about 384,000 kilometers. The most widely accepted scientific explanation for the moon’s origin is the “giant impact,” a high-energy collision between a Mars-sized proto-planet named Theia with the young “proto-Earth” about 4.5 billion years ago. As the newly formed moon cooled down from a hot magma ocean, layers with varying iron-content and mineral compositions crystallized to form the moon’s structure that we know today.
Superconductors—materials that can conduct electricity without energy loss—are crucial for next-generation high-efficiency, ultrafast electronics. However, most superconductors share a critical limitation: they lose their superconducting properties in strong magnetic fields. In contrast, a class of superconductors containing heavy elements can sustain an unusual type of superconductivity in magnetic fields beyond the conventional limit. Now, new research has demonstrated that this limitation can be overcome by sandwiching atomically thin films of a lightweight element called gallium between two other materials to engineer quantum interactions at the interfaces between the layers.
Researchers have discovered evidence that superconductivity can be controlled by influencing the surrounding environment, a finding that may lead to more efficient electronics down the road, according to a new study published in the journal Nature Physics.
The most realistic picture yet of how galaxies formed and then evolved from the beginning of time has been revealed in a suite of new and unique audiovisual simulations. These data, accepted for publication in the Monthly Notices of the Royal Astronomical Society, show that the standard cosmological model can successfully explain the observed growth of galaxies, from the first billion years after the Big Bang to the present day, when key physics is included.
The simplicity of a hydrogen atom makes it an ideal model for studying atomic structure and interactions. Yet, despite the fact that its simplest form consists of only one proton and one electron, physicists have had a hard time pinning down the exact charge radius of the proton. But a new study, published in the journal Physical Review Letters, outlines a method of measurement that helps to resolve some past discrepancies.
Since July 2025, the European Space Agency’s pair of Proba-3 satellites has already created 57 artificial solar eclipses. So far, the mission has collected more than 250 hours of high-resolution videos of the sun’s atmosphere, called the corona. That’s the same amount of observing time as about 5,000 total solar eclipse campaigns carried out on Earth.
Across Earth, every night, thousands of automated stargazers are waiting to take pictures of shooting stars. I am one of the scientists who study these meteors.
Look up at a full moon on a clear night and you are staring at a face that has been punched, gouged, and battered for 4 billion years. Those dark patches are vast basins blasted open by impacts so colossal they reshaped a world. The lighter highlands are pocked and pitted, crater upon crater, each one a frozen record of a collision that happened long before humans walked Earth. Unlike our own planet, the moon has no weather to smooth things over, no rivers to fill the hollows, and no wind to soften the edges. What hits it stays.
Physicists in China have simulated the effect of “false vacuum decay”: a phenomenon believed to play out constantly in the seemingly empty expanses of space, and which one theory even suggests could bring an abrupt end to the entire universe. In a paper published in Physical Review Letters, Yu-Xin Chao and colleagues at Tsinghua University, Beijing, mimicked the effect using a simple tabletop experiment.
The man was allegedly holding the vehicle’s driver against her will and had stabbed her the day before; he resisted Chino PD officers, claiming to be suffering a heart problem
An international team including the University of Bern (UNIBE) and the University of Geneva (UNIGE), members of the National Center of Competence in Research PlanetS, has succeeded in mapping the climate of rocky exoplanets with masses similar to Earth for the first time. This breakthrough is based on continuous observations using the James Webb Space Telescope.
