A team of professional and amateur Japanese astronomers have found evidence for a thin atmosphere around a small body in the outer solar system. The object is so small that it should not have a sustainable atmosphere, raising questions about when and how the atmosphere formed. Future observations to better characterize the atmosphere will help solve these mysteries.
Quantum technology has promising potential to revolutionize how large and complex amounts of information are processed. While already in use primarily in laboratory and research settings globally, quantum technologies are in a transition phase for broader industry applications across many economic sectors.
In researching fundamental aspects of quantum physics, or the behavior of nature at the smallest scales—involving atoms, electrons and photons—a study led by Cal Poly Physics Department Lecturer Ian Powell analyzed how a changing magnetic field can make matter behave in unusual ways.
Powell and student researcher Louis Buchalter, who graduated with a Cal Poly bachelor’s degree in physics in 2025, published the article “Flux-Switching Floquet Engineering” in the journal Physical Review B, highlighting how changing magnetic fields over time can create quantum states that do not exist in any stationary material (remaining in the same state as time elapses).
Astronomers have finally identified where the Milky Way’s star-making activity fades, uncovering a long-sought boundary in our galaxy.
A new sound-based laser could measure gravity with unprecedented precision and reshape navigation technology.
Since their introduction in the 1960s, lasers have fueled major advances in science and everyday technology, from supermarket scanners to eye surgery. Traditional lasers operate by controlling photons, which are particles of light. Over the past two decades, researchers have expanded this concept to other particles, including phonons, which represent tiny units of vibration or sound. Learning to control phonons could unlock new capabilities, including access to unusual quantum effects such as entanglement.
Squeezed Phonon Laser Advances Precision.
The repeated evolution of similar phenotypes, or convergent evolution, is widespread in nature, but there are few studies investigating the genetic mechanisms across wide evolutionary timescales. This study examines convergent wing pattern evolution across highly divergent Lepidopteran lineages and reports parallel genetic reuse, indicating strong constraints and high predictability in evolutionary outcomes.
